Centro de Química e Bioquímica, DQB Faculdade de Ciências, Universidade de Lisboa Campo Grande 1749-016 Lisboa, Portugal Phone: (351) 21 750 0000 Fax: (351) 21 750 0088 http://cqb.ciencias.ulisboa.pt/ CQB The Centro de Química e Bioquímica was founded in 2001 aiming at creating an environment oriented toward fruitful collaborations between chemistry and biochemistry. The multidisciplinary teams working in the experimental and theoretical labs within CQB involve approximately sixty PhD members and more than one hundred collaborators, most of them PhD and Master students. The lively and youthful atmosphere of the Faculdade de Ciências extends to CQB and is further amplified by the large number of international collaborations and programs (students from ERASMUS, IAESTE and others). We conduct fundamental research disseminated by recognized peer-reviewed scientific journals, and the high number of citations reflects its relevance to the scientific community worldwide. CQB research is organized in two thematic lines, aligned with the Societal Challenges defined in Horizon 2020 EU, the priorities for the regional development of the Lisbon area, and taking advantage of the consolidated skills of CQB members: Chemistry and Biochemistry for a Clean Environment Healthy Life: Molecular Interventions and Regulation Mechanisms I invite you to read this pages, visit our web pages and know more about us and our research!

M. de Almeida (FCT Principal Investigator) ↘Aligned with H2020 Societal Challenges ↘Aligned with Lisbon area regional priorities 22 Chemistry and Biochemistry for a Clean Environment Overview and goals Chemistry and Biochemistry for a Clean Environment focuses on the European societal challenges to develop methodologies that ensure a clean and healthy environment. To achieve this, new ways of identifying, assessing, preventing, controlling, or efficiently removing contaminants, thereby reducing human health risks, will be addressed. In parallel, we create selective and environment friendly catalyst for industrial relevant processes. CQB has the expertise to synthesize and characterize new molecules and materials able to degrade contaminants, to adsorb pharmaceutical remains, to obtain heterogeneous and homogeneous catalysts to improve industrially relevant reactions. 23 Chemistry and Biochemistry for a Clean Environment Overview and goals These efforts combined with those purveying analytical methods development and biochemists conducting research oriented to the evaluation of their impact on human health will contribute to improve the cleanliness of the environment. The support of groups with expertise in computational studies, determination of properties and characterization of molecules and materials will significantly improve the knowledge needed to live in a Clean Environment, one condition at the heart of the idea of Healthy Ageing! These potentialities will lead to the creation of environment-friendly and decontamination technologies, new methods for decontamination control and residual hazard assessment, and for evaluation of their impact on human health. 24 Chemistry and Biochemistry for a Clean Environment Key publications 2015 - 2016 Layered Double Hydroxide Nanocluster: Aqueous, Concentrated, Stable, and Catalytically-Active Colloids towards Green Chemistry, Y.

The synergies afforded by the multidisciplinary research team of CQB provide optimal conditions to be at the forefront of this research area. Several chemistry oriented labs are proficient in synthesizing or obtaining from natural sources novel molecules with potential high-value bioactive properties. On the other hand, biochemists are conducting research on the biological mechanisms underpinning health and disease. The preventive and therapeutic properties of new molecules obtained by chemists can, therefore, be investigated in the framework of the most advanced and updated biochemical knowledge. Marine Natural Products 27 Healthy Life: Molecular Interventions & Regulation Mechanisms Overview and goals The combined efforts of several labs in this thematic line will be directed towards the promotion of healthy habits in the general population and catalyzing novel collaborations with the business world. In summary, with this thematic line we aim at providing key scientific contributions to a fast incorporation of chemical and biochemical knowledge into the society, thus effectively contributing to a healthier and more active life!

Different products are under study, e.g. carbon materials which are usually obtained from sub products of agricultural or industrial activities or by template methodologies; natural-clay based solids and metalorganic frameworks. Polyurethane matrixes with different compositions, and physical properties (e.g. hydrophobicity), are also developed to be used as supporting adsorbent materials. Applications of these porous materials include the separation of alkenes from alkane/alkene mixtures, the purification (upgrade) of biogas and natural gas by removing carbon dioxide and nitrogen. Special interest has been given to the use of carbon materials as adsorbents for the removal of emergent pollutants (e.g. pharmaceutical compounds) from water. Additionally, functionalization of porous materials with transition metal complexes using different methodologies for encapsulation is a an hot topic within AAM group. The main goal is to obtain heterogeneous complexes which are catalytic active in the homogeneous phase. Regarding catalysis the group has also interests in the modification of zeolites structures aiming the improvement of their performance in refining and petrochemical processes as well as catalysts supports In the drug delivery systems frame, adsorption and release of nitric oxide was evaluated, by storing this compound in porous materials aiming a slow release which could be very helpful for therapeutic applications. http://adsorption.fc.ul.pt/ 33 SAPO Highlight Hierarchical zeolites to higher performance catalysts Hierarchical Zeolites Mesoporosity Intercrystalline Intracrystalline Modification of MCM-22 zeolite through sequential post-synthesis treatments. Implications on the acidic and catalytic behaviour, V. Machado, J. Rocha, A.P. Carvalho, A. Martins, Appl. Catal., A: Gen, 2012, 445, 329-338. Zeolites are crystalline materials with a wide range of applications, especially as heterogeneous catalysts. However, the microporous nature of these materials limits its application in the presence of large molecules with industrial interest The development of hierarchical zeolites (micro + mesopores) aims to increase molecular diffusion and the access to the active sites, extending the range of application for these materials in refining, petrochemistry and fine chemistry reactions. 34 Highlight From biomass to carbon materials to enhance water treatment technologies Processo de produção de carvão activado a partir de material de cortiça S.P.Martins, A.S.

Water contamination with pharmaceutical compounds is a reality worldwide and scientists and governmental entities consider that this kind of contamination may require legislative intervention. In fact, pharmaceutical compounds appear in a Watch List in the 2013/39/EU directive and, for now, activated carbons which are non-specific adsorbents, appear as the best available decontamination technology for the removal of the pollutants that have a recalcitrant behaviour in conventional water treatment plants. The biomass-derived activated carbons developed in the Adsorption and Adsorbent Materials group of CQB outperform commercial samples in the ability to remove even the most recalcitrant pharmaceuticals from water. 35 Highlight Materials for storage and slow release of therapeutic gases L-Histidine Based Organoclays for the Storage and Release of Therapeutic Nitric Oxide, A.C.

Pires, Journal of the American Chemical Society, 2011, 133, 6396–6402 Nitric oxide (NO) is a small endogenous molecule with particularly interesting effects on biological systems, despite its toxicological potential. The delivery of nitric oxide in controlled amounts to the human body is an attractive therapeutic alternative for a large number of pathologies. NO is involved in neurological functions in synaptic plasticity, neurotransmission, learning, and memory, in addition to having a primary role in non-specific immunity and platelet aggregation inhibition. NO is a gas at room temperature and pressure, unlike more common drug molecules that are usually in a solid or liquid state. Because of the limited utility of genuine NO gas in many experimental systems and the short half-life of NO in vivo, compounds that have the capacity to release NO have been researched. More recently, nanoporous materials were explored for their ability to act as NO delivery platforms, particularly for topical applications in dermatology, wound healing, and organ conservation. 36 Carbohydrate Chemistry Based on a sustainable model, starting from sugars or from natural resources towards new drug candidates or functional food ingredients for pharmaceutical and/or food industries, the Carbohydrate Chemistry Group aims to provide economic and social benefits in terms of prevention of functional decline and ageing, nutrition, health and biosecurity.

Advanced mass spectrometry, ‘Hyphenated’, tandem MS, high resolution (FTICR MS) and spectroscopic techniques, applied to environmental, biochemical/biological, conservation and forensic sciences, enable the structural characterization of compounds, even at trace level, and in complex matrices (as for example degradation products of emerging contaminants in the aquatic environment), of particular importance to the elucidation of chemical and biochemical reaction mechanisms and to the development of decontamination processes encompassed in the strategic area entitled Sustainable Chemistry for Functional Molecules and Materials, defined for CQB. These advanced analytical capabilities are also of major importance and a key issue for characterization and properties evaluation of bioactive molecules that can potentially contribute for the development of novel therapeutic agents and medicines and for evaluation of the effectiveness and safety of these molecules. Theoretical methodologies are also applied as a support for rationalization of molecular ion structure, mechanisms and gas-phase thermochemistry data. https://www.fc.ul.pt/pt/unidade/grupo-de-espectrometriade-massa-ambiental-e-biológica 45 Highlight Intensidade Relativa (%) Infusions can have beneficial health effects and may be useful for lowering cholesterol in the bloodstream and digestive process facilitation 100 79 91 92 100 149 215 165 179 184 50 0 80 120 m/z 160 200 240 Studies on the molecular mechanism of cholesterol reduction by Fraxinus angustifolia, Peumus boldus, Cynara cardunculus and Pterospartum tridentatum infusions, P.L.

The high cholesterol level in the blood can be mentioned as being among the main causes of these diseases. The first and most simple action to reduce cholesterol level is to decrease its ingestion in the diet. When this action is not enough, drugs start to be prescribed. Herbal teas, or infusions, used for a wide range of purposes can also be used to diminish cholesterol in the blood. Although these compounds cannot be sold with claims for health benefits, it is well known that they are sold and consumed in order to improve people's health. Functional foods, among which are herbal teas, of natural origin, have been the subject of our studies. In our laboratory we have long been studying “teas” from plant origin, to determine their composition by mass spectrometry techniques and also in what concerns their initial and final biochemical activity after the gastro-intestinal digestion. The results of these studies, besides highlighting the components of those mixtures, which is important for their quality control, also show that the infusions can have beneficial effects to health and can be used, for example, for lowering cholesterol in the bloodstream and to facilitate the digestive process. 46 Enzymology Enzymes are the core of life. It is our mission to unravel enzyme function and structure, exploring the exquisite complexity of life through a systems biology approach. Our final goal is to shape the rules of life to our defined purposes such as changing enzyme specificity, rewiring pathways and creating novel functional macromolecular structures. Our research comprises the role of protein glycation, the glyoxalase pathway and protein-protein interaction networks in transthyretin amyloidosis as well as a systems biology approach to human infectious diseases, namely leishmaniasis and pneumococcal diseases. We are seeking enzymes and pathways towards novel therapeutic opportunities against these human pathogens. Our tools are a combination of computational methods, mostly implemented through in house designed software, biochemical and molecular biology techniques, as well as advanced analytic tools, including FTICR-MS, enabling research in metabolomics and proteomics. We are continuously improving these tools and expanding the scope of its applications, most notably in the field of mass spectrometry, with the development of native MS, topdown proteomics and 2DFTICR-MS. We spawned and support a biotech start-up, BioMimetx, dedicated to deliver innovative solutions for the control of biological proliferation, most notably, biofouling in marine environments.

We develop new organometallic complexes and materials (porous solids, nanoparticles and ionic liquids) to obtain new homogeneous and heterogeneous catalysts, aiming at improving (enantio)selectivity in industrially relevant reactions. We also immobilize bioactive compounds to get new non-leaching bioactive polymeric materials to protect surfaces against biofouling. Functional nanomaterials and devices of magnetic molecules based on spin crossover to provide polymeric, amphiphilic or nanocrystalline environments are being synthesized, as well as materials for electrochemical CO2 reduction. Bioactive natural products are isolated in the quest for new drug leads from Portuguese marine organisms. New psychoactive substances marketed as recreational drugs in Portugal are identified by NMR. We use Quantum Chemistry to study mechanisms of organometallic reactions, to calculate the properties of molecules and materials in order to improve functionalized materials, and to understand in detail the interactions between bioactive metal complexes and polyoxometalate derivatives with biomolecules an materials. With the help of molecular modeling and simulation, we are interested in the study of the dynamic properties of membranes and proteins, their pHdependence and relation with disease. Additionally, the modeling of non-conventional bonds (such as halogen bonds) in (bio)chemical systems aiming at drug design is also pursued.

MacDiarmid and Hideki Shirakawa for the discovery that plastic is able to conduct electricity after being conveniently modified. Since then, researchers and their groups have developed efforts to find new polymeric materials with conducting properties. Our work aimed at the preparation of polymers incorporating metal ions in their polymeric backbone. This modification additionally confers both chemical and morphological properties opening possibilities to fine-tune materials for target applications. These materials showed good activity for oxygen reduction in aqueous medium. 51 Highlight Non-Releasing biocidal coatings: A new strategy for biofouling prevention The problem: BIOFOULING ON A SHIP HULL Functionalisation process for the biocides immobilisation in polymeric matrixes, E. R. Silva, O. Ferreira, J. C.M. Bordado, Patent PT Nº 10809, 2015. New Strategy to prevent adhesion of Biofouling to Coatings, E. R. Silva, O. Ferreira, J. C.M. Bordado, Short Communication, J. Adhesion Society of Japan, 2015, 51, 239-240. BIOCORROSION ON A SHIP HULL The potential solution 6 months of exposure in Atlantic seawater (Peniche, Portugal) With immobilised biocides Without biocides 5 cm Biofouling, a spontaneous colonization of surfaces in contact with water by aquatic organisms, is a global problem in water management systems of several industrial activities, and is responsible for serious environmental and economic consequences. For instance, its accumulation on hulls of ships can lead to drag friction increases up to 40 % and subsequent power penalties of up to 86% at cruising speed; when occurring in cooling circuits of power plants, it can lead to efficiency losses of about 5%. The main strategy to combat this biofouling relies on chemical control. However, this strategy has revealed to be harmful for the aquatic ecosystems, mainly owing to the ecotoxicity and cumulative effect of the applied bioactive agents. Therefore, rigid international regulations have been issued (BPD EU Regulation, 2012), and more are expected to come in a near future. New strategies, which can combine more efficiency against biofouling and non-toxic properties for the aquatic systems, are sought. Our Group developed a new antifouling environmental friendly strategy based on the covalent bonding of biocides in polymeric coatings (e.g. silicone based). This nonreleasing biocide strategy evidenced an effective biocide immobilisation, with promising coatings’ antifouling performance, up to 6 months to date, on seawater submerged coated surfaces with biocidal silicone based coatings. 52 Highlight Researchers at FCUL work with the Portuguese Police in the fight against the trade of NPS Compounds identified in seized products in Portugal. 4F-PBP (4’-fluoro--pyrrolidinobutyrophenone), a new substance of abuse: structural characterization and purity NMR profiling H. Gaspar, S. Bronze, S. Ciríaco, C. Leal, A. Matias, J. Rodrigues, C. Oliveira, C. Cordeiro, S. Santos, Forensic Sci. Int., 2015, 252, 168-176. In the last decade, more than 450 new psychoactive substances (NPS) appeared in the market of drugs of abuse. The fast dissemination of these new drugs in the internet created an emerging need for developing new analytical methodologies for their rapid identification. Since May 2014, a team of researchers of FCUL, led by Helena Gaspar, researcher at the Centro de Química e Bioquímica, works in collaboration with the Laboratório de Polícia Científica da Polícia Judiciária in the identification and quantification of NPS in products seized by the Portuguese police. Recently, this team has identified, for the first time in Europe, a new synthetic cathinone, 4F-PBP. The results have already been published in the journal Forensic Science International 2015. This outcome highlights the importance of the academia in supporting the resolution of current problems in our society, as the control of of NPS’s trade. The work developed by the group of FCUL consists in the isolation and structural characterization of NPS, by means of NMR spectroscopy and Mass Spectrometry, from products supplied by the LPC, or in their synthesis, allowing not only their toxicological evaluation, but also the supply of NPS standards to forensic laboratories, to be used in routine analyses. 53 Highlight Biodegradable polymers using monomers from plants Dinuclear Zinc–N-Heterocyclic Carbene Complexes for Either the Controlled Ring-Opening Polymerization of Lactide or the Controlled Degradation of Polylactide Under Mild Conditions, C. Fliedel, D. Vila-Viçosa, M. J. Calhorda, S. Dagorne and T. Avilés, ChemCatChem, 2014, 6, 1357. Polylactide (PLA), a biodegradable thermoplastic polyester derived from lactic acid, is a renewable resource, currently attracting attention for applications ranging from biomedical to food packaging and device applications. It is considered a promising alternative to petrochemical-based plastics and the fast growth of its production capacity (150,000 tons/year currently) suggests it will be a high volume commodity material in the near future. In collaboration with an experimental team, we used a computational approach to calculate the energy of all the intermediates and transition states of the full mechanism of the ring opening polymerization (ROP) of lactide catalyzed by a binuclear Zn(II) complex in mild conditions. We identified the determining steps and the cooperative role of the two zinc centers. Indeed, detailed knowledge of the reaction will allow the optimization of the process, namely improving the catalyst (cheaper, more active), and the reaction (environmentally friendlier). 54 Highlight Intercalation in DNA: Small changes in the structure that become powerful for diseases How the Intercalation of Phenanthroline Affects the Structure, Energetics, and Bond Properties of DNA Base Pairs: Theoretical Study Applied to Adenine-Thymine and Guanine-Cytosine Tetramers, A. Gil, M. Melle-Franco, V. Branchadell, M.J. Calhorda, J. Chem. Theory Comput., 2015, 11, 2714. Since the incorporation of cisplatin in chemotherapy, the interest in the application of metal systems in medicine has grown rapidly. One step beyond was the incorporation of phenanthroline (phen) ligand in metal complexes, these systems showing significant antitumoral activity. Within the interactions of coordination complexes with DNA, intercalation is an important binding mode and the intercalative capacity of molecules is influenced by the planarity of ligand, type of donor atom, and metal coordination geometry. Thus the aim of this work was the comprehension and rationalization of the interaction of phen with DNA strands by means of computational techniques. The results showed that intercalation produces important changes of geometric parameters of the base pairs. For the systems containing guanine and cytosine, hydrogen bond interactions are more important than stacking interactions, whereas for the systems with adenine and thymine these stacking interactions become competitive. Moreover, the contribution of dispersion forces is the most important contribution to explain the interaction. Nevertheless, this contribution is necessary but not sufficient to stabilize the Pauli repulsion contribution originating between electrons of different fragments having the same spin. Thus, charge transfer contribution (small) and the electrostatic contribution (more important) play an important role to stabilize the intercalator and compensate Pauli repulsion. In fact, the values of the electrostatic contribution are roughly similar to the values of the interaction energy. 55 Highlight Adding realism to computer simulations of cell membranes Treatment of ionic strength in biomolecular simulations of charged lipid bilayers D. Vila-Viçosa, V. H. Teixeira, H. A. F. Santos, A. M. Baptista, M. Machuqueiro, J. Chem. Theory Comput., 2014, 10, 5483. Biological membranes are complex systems that have recently attracted significant scientific interest. Experimental techniques are very limited in measuring the physicochemical processes near membranes. On the other hand, computational methods are very useful since they allow us to study the molecular details of several lipid bilayer disorders, associated with diseases like the Barth syndrome. The presence of many charged lipids, render these membranes sensitive to pH. The protonation states of lipids and the ion distribution close to the bilayer are two of the main challenges in biomolecular simulations of these systems. In this work, we proposed a new method based on the Poisson–Boltzmann equation to estimate the ion concentration near a lipid bilayer that avoids the need for neutrality at the microscopic level. This new methodology allows for an increased realism in our molecular simulations and can have an important contribution in future studies. 56 Highlight New generation of green catalyst from known materials Layered Double Hydroxide Nanocluster: Aqueous, Concentrated, Stable, and CatalyticallyActive Colloids towards Green Chemistry Y. Tokudome, T. Morimoto, N. Tarutani, P. D. Vaz, C. D. Nunes, V. Prevot, G. Stenning, M. Takahashia ACS Nano, 2016, 10, 5550–5559. Increasing attention has been dedicated to the development of nanomaterials rendering green and sustainable processes, which avail in benign aqueous reaction media. Nanocatalysts exhibit a significant contact with reactants and allow separation from products, simultaneously achieving the advantages of heterogeneous and homogenous catalysts. Layered double hydroxide (LDH), which is a family of lamellar metal hydroxides accommodating anions in their interlayers, is a promising candidate as a green catalyst. We demonstrate the synthesis of a family of green nanomaterials, layered double hydroxide (LDH) nanoclusters, which are concentrated (98.7 g/L in aqueous solvent), stably dispersed (transparent sol for >2 weeks), and catalytically-active colloids of nano LDHs. LDH nanocluster is available as colloidal building blocks to give access to meso/macroporous LDH materials. Thus obtained LDH NC catalyze Knoevenagel condensation and olefin epoxidation. The catalytic activity is comparative or higher compared to the cases of using standard LDHs, and revealed that the LDH nanocluster works as a solid basic catalyst and is separable from solvents of catalytic reactions, confirming the nature of nanocatalysts. 57 58 Interfacial Electrochemistry Fullerene adsorption on Au Interfacial Electrochemistry Group research is focused on interfacial phenomena involving high performance modified electrodes and semiconductor nanomaterials, to develop new platforms for (photo)electrocatalytic, energy production, (bio)sensing and protective purposes. This is achieved by a careful and precise combination of materials (conducting polymers, self-assembled monolayers and nanostructures) and preparation methods (electrochemical, chemical coupling/adsorption, modification/sensitization). In catalysis and sensing is extremely advantageous and challenging to have active centres stably immobilized preserving their identity and function. Association of electrochemical and surface sensitive characterization techniques greatly contributes to elucidate about structure, properties and reactivity relationships. Benefits arise from the use of functionalized electrodes, since reactive entities properties can be tailored and modulated by electric potential application. 1.001 nm DPPC: Cholesterol : 1-decanethiol Electropolymerisation of EDOT/FcPF6 Additionally, the materials evaluation in energy production and environmental remediation processes, are studied in the IEG group. Another research line, is the evaluation of the effect of bioactive chemicals and proteins on biomimetic supported lipid bilayers, mainly by high resolution imaging. 1201 1177 1153 1129 1105 1081 1057 1033 1009 985 961 937 913 889 865 841 817 793 769 745 721 697 673 649 625 601 577 553 529 505 481 457 433 409 385 361 337 313 289 265 241 217 193 169 145 121 97 73 49 25 1 Titanate nanotubes photosensitization 0 10 TNTs surface absorvance (a.u.) + organic dyes http://electro.fc.ul.pt/ Series1 TNTs/MB 30 40 TNT-dye TNT 50 TNTs 250 350 450 550 wavelength (nm) 59 20 650 750 850 60 Highlight Organometallic/polymer matrices for highly sensitive dual electrochemical and optical assessment of Biochemical Oxygen Demand (BOD) Dual sensor optical and electrochemical response, towards O2 Improved potentiometric and optic sensitivity of polyaniline film to dissolved oxygen by incorporating iron-porphyrin, M. Li, I. M. Ornelas, W. Liu, Y. Niu, J.P.Correia, A. S. Viana, and G. Jin, Electroanal, 2015, 27, 1 – 10. Electronically conducting polymers (or conducting plastics) are well known electrochromic materials. They undergo reversible colour modifications according with the electrical potential they are submitted. On the other hand, some metalloporphyrins like the iron-porphyrin - that we can find in hemoglobin – are very sensitive to the presence of oxygen, which induces redox transformations in the molecule. Incorporating the iron porphyrin into a polyaniline (conducting polymer) matrix, resulted in a high sensitive oxygen sensor. In a cooperative work of the Centre of Chemistry and Biochemistry from Ciências and the Chinese Academy of Sciences, a novel oxygen sensor for Biochemical Oxygen Demand assessment with dual transduction was developed. The interaction of the dissolved gas with the porphyrin provokes a spontaneous adjustment of the intrinsic electric potential of the polymer causing the modification of the optical properties of the material. In this way, both the electric signal and the optical response of the polymer reflect to the presence and amount of dissolved oxygen. The optical monitoring of the electrode is performed by TIRIE (Total Internal Reflection Imaging Ellipsometry) which is a technique highly sensitive to changes of the dielectric properties of the samples. The combined electrochemical and optical signals strongly corroborate each other, allowing the normalization of the readings in repetitive measurements using the same modified electrode. 60 Highlight Titanate nanofibers co-sensitized with ZnS and Bi2S3 nanocrystallites for pollutants removal Synthesis of titanate nanofibers co-sensitized with ZnS and Bi2S3 nanocrystallites and their application on pollutants removal, T.J. Entradas, J.F. Cabrita, B. Barrocas, M.R. Nunes, A.J. Silvestre, O.C. Monteiro, Mater. Res. Bull. 2015, 72, 20-28. The use of nanocrystalline semiconductors as photocatalysts, on the treatment of industrial wastewaters, has generated great interest, due to their unique physicochemical properties. In particular this project aims TNTs manipulation by surface sensitization processes, through the synthesis of nanocomposite materials combining titanate nanofibers (TNF) with nanocrystalline ZnS and Bi2S3, in order to obtain nanocomposite materials with new and improved photocatalytic performances. The TNF were produced via hydrothermal synthesis and sensitized with the semiconductor nanoparticles, through a single-source precursor decomposition method. ZnS and Bi2S3 nanoparticles were successfully grown onto the TNF’s surface and Bi2S3–ZnS/TNF nanocomposite materials with different layouts. The samples’ photocatalytic performance was first evaluated through the production of the hydroxyl radical using terephthalic acid as model molecule. All the tested samples show photocatalytic ability for the production of this oxidizing specie, very important in the photodegradation of organic pollutants. Afterwards, the samples were investigated for the removal of methylene blue. Methylene blue is an industrial dye, used often as model pollutant in photocatalytic degradation studies. From the nanomaterials materials studied, the nanocomposites with best adsorption ability were the ZnS/TNF and Bi2S3ZnS/TNF. The most promising results, for the complete pollutant removal, were obtained considering a sequential combination of an adsorption-photocatalytic degradation process using the Bi2S3ZnS/TNF powder as a highly adsorbent and photocatalyst material. 61 Highlight A platform to study membrane nanodomains and redox processes of bioactive molecules in different lipid environments A Biomimetic Platform to Study the Interactions of Bioelectroactive Molecules with Lipid Nanodomains, J. T. Marquês, A.S. Viana, and R. F. M. de Almeida, Langmuir 2014, 30, 12627−12637. Supported lipid bilayers (SLB) are a very useful model system of biological lipid membranes to study membrane-related phenomena, since it allows the use of a great variety of very sensitive surface techniques. In particular, if SLB are prepared on metallic surfaces, electrochemical and optical methods can be employed expanding their applications, namely on biosensing. There has been a great effort in the development of SLB on gold surfaces, though most of the studies only concern single-component or single-phase lipid systems, then failing to mimic the mammalian plasma membrane. This work results from a close collaboration with the Molecular Biophysics group and is focused on the design of planar, continuous and stable multicomponent lipid platforms on gold with distinct phase behavior. Such lipid interfaces enable to detect, with high sensitivity, redox processes of molecules interacting with membranes, such as ubiquinones, flavonoids, and cathecolamine hormones or proteins. Currently, we are developing lipid-based biointerfaces for immunosensing, which combine a number of important characteristics in a biosensor, namely: biomimetic environment, ability to block nonspecific interaction with serum proteins, a robust arrangement regarding a continuous flow of buffer solutions (even in the presence of surfactant), and high sensitivity. 62 Molecular Biophysics The main goal of our group is to advance the state-of-the art of membrane lipid domains, providing means for improved assessment of their involvement in drug mechanisms of action, pointing directions to develop new drugs/drug-formulations. Biological membranes are organized into (micro)domains consisting of regions with different lipid and protein composition, properties and functions. Furthermore, several pathologies, including cancer and neurodegenerative conditions, are characterized by specific alterations in lipid composition and hence membrane biophysical properties. Moreover, the molecular mechanism of action of many drugs involves at some point their effect on membrane lipid organization (the membrane-lipid therapy principle). Thus, fundamental research on membrane domains in both physiological and pathological situations will take place in parallel with the study of compounds that can potentially promote health and prevent functional decline. Several molecular biophysical approaches are used to tackle the complex interactions between these agents and biomembranes, proteins and DNA, with potential benefits for society. We use design-and-synthesis approaches to develop new compounds, bio-inspired and from natural origin, namely, essential oils from aromatic and medicinal plants, seeking the valorization of Portugal and CPLP countries natural resources. In addition, we address the following important topics: • Development of synthetic receptors for chiral resolution of drugs and for the transmembrane transport of anions. • Research of natural pesticide for control of insect vectors of human pathogens (e.g. malaria and dengue). http://bmn.cqb.fc.ul.pt/ 63 Highlight Ecofriendly Biolarvicide for mosquito control Ae. aegypti larvae morphological alteration Larvicidal Activity Against Aedes aegypti of Foeniculum vulgare Essential Oils from Portugal and Cape Verde, D.K.Rocha, O.Matos , M.T.Novo, A.C.Figueiredo, M.Delgado, C.Moiteiro; Nat. Prod. Commun., 2015, 10(4), 677-682. Dengue has recurrent epidemics in Latin America and occurred recently in Cape Verde and Madeira Island. The lack of anti-viral treatment or vaccine makes the control of mosquito vectors a high option to prevent virus transmission. The use of plants for insect control has increased worldwide, with particular emphasis on search of essential oils (EOs) obtained by hydrodistillation. The present study evaluated the potential use of Foeniculum vulgare (fennel) EO in the control of the dengue vector Aedes aegypti. EOs isolated from fennel aerial parts collected in Cape Verde and from a commercial fennel EO of Portugal were analyzed by NMR, GC and GC-MS. trans-Anethole (32 and 30%, respectively), limonene (28 and 18%, respectively) and fenchone (10% in both cases) were the main compounds identified in the EOs isolated from fennel from Cape Verde and Portugal, respectively. The larvicidal activity of the EOs and its major constituents were evaluated, using WHO procedures, against third instar larvae of Ae. aegypti for 24 h. Pure compounds, such as limonene isomers, were also assayed. The lethal concentrations LC50, LC90 and LC99 were determined by probit analysis using mortality rates of bioassays. A 99% mortality of Ae. aegypti larvae was estimated at 37.1 and 52.4 μL L-l of fennel EOs from Cape Verde and Portugal, respectively. Bioassays showed that fennel EOs from both countries displayed strong larvicidal effect against Ae. aegypti, the Cape Verde EO being as active as one of its major constituents, (-)-limonene. These results suggest the potential application of fennel EO as a possible natural larvicidal for the control of the major dengue mosquito vector. 64 Highlight A New Lipid Order: Advancing Our Knowledge on Biomembranes and Using It to Improve Human Health Biological membranes are generally believed to exist in a fluid regime, where a liquid disordered (ld) phase with low lipid packing and fast lateral diffusion of molecules coexists with a liquid ordered (lo) one displaying higher lipid packing and slightly slower lateral diffusion. In recent years, however, our studies have challenged the dogma that another lipid phase, the gel or solid ordered phase, is not physiologically relevant, due to the very slow lateral diffusion of its components. We have proved that gel domains are present in the plasma membrane of growing yeast cells through the use of fluorescent probes that exhibit different fluorescence parameters in each lipid phase [1]. This finding is now supported by independent studies in other laboratories. More recently, in an attempt to understand the formation and properties of gel domains in biomembranes, we undertook a series of experiments using a common glycerophosphospholipid, the phosphatidylcholine (POPC) and phytoceramide, the backbone of the complex sphingolipids found in plants and fungi, also present in several human tissues such as skin [2]. Our findings using fluorescent probes and liposome suspensions pointed to the formation of POPC : phytoceramide stoichiometric complexes (with stoichiometries 3:1 and 1:2) that display unique biophysical properties [2]. Experiments using atomic force microscopy in supported lipid bilayers, confocal fluorescence microscopy in giant liposomes and X-ray scattering in multibilayers corroborated the supramolecular organization of the lipids into complexes. Interestingly, the fluorescent parameters (anisotropy and lifetimes), exhibited by fluorescent probes in liposome suspensions [2] were identical to the ones obtained for living yeast cells [1], which show that the gel domains identified in vivo may share important properties with the stoichiometric complexes formed in the POPC/phytoceramide mixtures. 65 Recently, our group has contributed with a hypothesis/theory paper, proposing a model “whereby seeds comprised of oligomerised proteins and/or lipids would serve as crystal nucleation centers for the formation of diverse gel/crystalline nanodomains”, the nanodocks model [3]. Moreover, we presented a book chapter, where the literature reports pointing for the formation of highly ordered lipid domains in vivo was critically reviewed [4]. The relevance that ordered domains may play in the organization and function of biomembranes, and their implication in drug modes of action, and antidrug mechanisms of resistance, both in infectious agents and in cancer cells, were discussed.

The thermodynamic stability of molecules, as measured by standard enthalpies of formation and “bond strengths”, can, for example, be rationalized by investigating the relationships between those properties and bond lengths and angles, steric and electronic parameters, activation energies, etc. The energetics of intermolecular interactions regulates phenomena such as the dissolution of a solute in a solvent and the structural organization of molecules in crystals. By probing these interactions it is possible, for example, to understand many aspects of polymorphism occurrence and to elucidate the role of solvents in chemical reactivity. Monitoring the production of heat by living organisms can also provide important clues about their adaptation to environmental changes. The research carried out at the Molecular Energetics group relies on a variety of experimental techniques, such as X-ray diffraction, microscopy, reaction and combustion calorimetry, Calvet-drop microcalorimetry, flowcalorimetry, time-resolved photoacoustic calorimetry, differential scanning calorimetry, thermogravimetry, crystallization reactors, and Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR-MS), along with quantum chemical methods and molecular dynamics simulations. The group has a long tradition in instrument building and database development. http://molenergetics.fc.ul.pt/ 67 Highlight Size Matters: The Stability of NaCl, the Most Abundant Salt on Earth, Considerably Changes on Entering the Nano World Size Matters: An Experimental and Computational Study of the Influence of Particle Size on the Lattice Energy of NaCl, S. Range, C. E. S. Bernardes, R. G. Simões, M. Epple, M. E. Minas da Piedade, J. Phys. Chem. C, 2015, 119, 4387-4396. One of the most interesting features of nanomaterials is the change in properties that normally accompanies a decrease in particle size. Using calorimetric experiments and atom-atom pair potential calculations, we were able to show, for the first time, that the stability of sodium chloride, the most abundant salt on earth, considerably decreases (>30%) with the decrease of the crystal size up to the single molecule dimension. The decrease is particularly steep for crystal sizes below 100 nm. The results further suggested that the cohesive energy within each crystal layer varies from site to site, with the energy differences between adjacent sites decreasing on moving from the periphery to the centre of the crystal. As expected, the atoms at the outmost surface layer exhibit the lowest cohesive energies. 68 Highlight The Thermochemistry of Cubane 50 Years after Its Synthesis The Thermochemistry of Cubane 50 Years after Its Synthesis: A High- Level Theoretical Study of Cubane and Its Derivatives, F. Agapito, R.C. Santos, R.M. Borges dos Santos, J.A. Martinho Simões, J Phys Chem A, 2015, 119, 2998-3007. Cubane is a unique molecule for its extraordinary C8 cage, where all the sp3 hybridized carbon atoms have C–C–C bonds angles of 90°. It is therefore one of the most strained compounds known and, until its synthesis in 1964, there was doubt that such a molecule could even hold together. But cubane turned out to be a surprisingly stable molecule, since no kinetically viable paths exist for its thermal decomposition. The synthesis of cubane was driven by the curiosity and fascination of organic chemists in obtaining the molecular equivalent of a platonic solid. Nevertheless, its derivatives have many important potential applications, such as in high-energy fuels, explosives and propellants (e.g., octanitrocubane), and as an intermediates in pharmaceutical preparations. Because the cubane frame is rigid, substituents will have precise spatial relationships to each another. This offers fascinating substituent positioning possibilities for the synthesis of novel pharmaceuticals. To assess viable synthetic pathways, knowledge on the energetics of the cubane molecule and its reactive intermediates is needed. In general, this kinetic modeling requires “chemical accuracy” of about ±4 kJ mol-1. We used highaccuracy state of the art computational methods to determine the enthalpies of formation of cubane and related compounds. 69 70 Redox Biology Group The Redox Biology group research focuses on hydrogen peroxide (H2O2), the main cellular oxidant now considered a key redox regulator. The long-term goal is to understand signalling pathways and molecular mechanisms by which H2O2 regulates physiological processes that, when unbalanced, lead to disease. H2O2, is continuously produced intracelullarly, as a byproduct of aerobic metabolism, and extracelullarly as a result of phagocyte activation. Our group uses an interdisciplinary approach, as the team is composed of people with a strong background in molecular biology, free radical biochemistry, cell biology and mathematical modeling, with a combination of both experimental and mathematical modelling approaches to study cellular redox regulation by hydrogen peroxide and its involvement in physiological cellular processes and in disease. The group expects to establish quantitative and cause/effect relationships between H2O2 levels and regulation of gene expression, organelle dynamics and disease. These studies will allow to identify molecular targets of H2O2 with possible therapeutic use in diseases, such as cancer and inflammation, and in aging. In addition, we aim at assessing the biological effects of emerging contaminants at sub-lethal concentrations. Our efforts will be focused on the biological adaptation induced by contaminants. For that we will use our knowhow on H2O2 adaptation acquired over the last decade. http://redox.fc.ul.pt/ 71 Highlight From oxidative stress to redox biology: understanding the cellular mechanisms of redox regulation by hydrogen peroxide Hydrogen peroxide sensing, signaling and regulation of transcription factors H.S.Marinho, C. Real, L. Cyrne, H. Soares, F. Antunes, Redox Biol. 2014, 2, 535-562. Top 10% Hydrogen peroxide (H2O2), a reactive oxygen species (ROS), is a ubiquitous oxidant present in all aerobic organisms. Since its first identification in a living cell, H2O2 was considered a toxic by-product of aerobic metabolism, something that cells had to remove. If H2O2 detoxification catalyzed by catalases and peroxidases was not adequate, H2O2 would diffuse and oxidize biological targets causing cellular malfunctions, i.e. oxidative stress, responsible for several pathologies and aging. Starting in the 90s this paradigm of hydrogen peroxide as toxic started to change to a paradigm where hydrogen peroxide acts in cellular regulation and is involved in cellular signalling – redox signalling – through the oxidation of thiols in proteins that act as redox sensors. Nowadays, redox biology is an established field and the essential regulating role played by H2O2 in vivo with important implications in health and disease is unquestionable. In this work it was shown that the complexity of redox regulation increases along the phylogenetic tree and that H2O2 modulates gene expression at all steps from transcription to protein synthesis. Also, some of the unanswered questions regarding our understanding of redox-dependent regulation of gene expression were addressed: What makes a good H2O2 sensor? What are the common chemical and kinetic principles that govern H2O2 signaling? Is it possible to obtain an integrative view of H2O2 regulation of transcription factors? 72 Separation Science & Technology Group The Separation Science & Technology (SS&T) group is composed by two research laboratories, namely, the Chromatography & Capillary Electrophoresis Lab. and the Hydrometallurgical Separations Lab. The common goal of our group is the development of new approaches to implement chemical separation techniques. The research work carried out by our group is based on two different research lines: The Chromatography and Capillary Electrophoresis line is involved on the development of new analytical methodologies to monitor trace levels of several classes of emergent compounds (e.g. EDC’s, PPCP’s, POP’s, DBP’s, etc.) from many type of priority matrices. Most of our analytical work has been focused on the implementation of novel sorption-based microextraction methodologies in combination with modern instrumental systems, in particular as analytical alternatives to monitor environmental, pharmaceutical, food, forensic and biological samples. The Hydrometallurgical Separations line focuses research on the development and characterization of new functional organic molecules to efficiently and selectively recover metal species from feed industrial complex aqueous solutions, and / or effluents. One of the aims is to contribute to the decontamination of the environment, through innovative processes for the hydrometallurgical recycling of end-of-life materials, and profiting from the economic value several metals in industrial wastes have. http://sepscitech.fc.ul.pt/ 73 Highlight New microextraction technologies for trace analysis of priority compounds PPCPs Drugs of abuse Pesticides Desinfection by-products Flavonoids Phenolic compounds Bar Adsorptive Microextraction (BAµE) Coated with Mixed Sorbent Phases - Enhanced selectivity for the determination of non-steroidal anti-inflammatory drugs in real matrices in combination with capillary electrophoresis, S.M.

A, 2010, 1217, 7303-7310 Recently, we have been involved in the development of new generation of microextraction devices, which are much more effective as sample preparation technologies, presenting easy and fast manipulation and are in compliance with the green analytical chemistry principles. In the analytical point of view they have been tested in monitoring trace and ultratrace levels of priority and emerging organic compounds, such pharmaceutical and personal care products, drugs of abuse, pesticides, disinfection by-products, flavonoids, phenolic compounds etc., in matrices from areas with impact in society at large. 74 Highlight Investigating the composition of the extracted species when sulfur-containing extractants are used for Pd(II) extraction from concentrated HCl solutions 0.19 1.47 4.0 6.03 3.5 0 0,0005 0,001 [Pd(II)] extracted / M 1.5 1.0 0.5 0 3 CH O 0,0015 1.09 0.89 1.07 0.88 0.86 6.51 5.64 3.28 5.74 2.01 2.28 0.42 3.0 2.5 2.0 Chemical Shift (ppm) MCHTA MPHTA 0 1.35 1.80 2.43 2.35 1.48 1.71 4.5 0,0005 1.66 1.64 2.89 0 2.95 0.25 y = 1.52x + 0.0005 R² = 0.983 0,001 0.50 3.54 3.49 3.45 0,0015 0.75 4.53 4.50 4.47 4.43 4.39 4.28 4.22 4.18 4.14 4.06 0,002 2.87 DMDCHTDGA 1.25 2.80 y = 2.07x + 0.0004 R² = 0.998 0,0025 Normalized Intensity Initial [extractant] / M 0,003 N O C H3 S N Palladium(II) Extraction from Concentrated Chloride Media – Reactions Involving Thioamide Derivatives, O.

Palladium(II) and N,N′-Dimethyl-N,N′-dicyclohexylthiodiglycolamide – the Extracted Species from Concentrated Chloride Solutions, O. Ortet, M.S.C.S. Santos, A.P. Paiva, Sep. Purif. Technol., 170, 1-9, 2016. A thiodiglycolamide and two thioamide derivatives have been developed for the liquid-liquid extraction of Pd(II) from concentrated HCl solutions. In addition to a remarkable efficiency towards Pd(II) extraction, these compounds are selective for this platinum-group metal (PGM) when this is part of complex metallic solutions coming from the hydrometallurgical treatment of spent industrial catalysts, e.g., containing excess concentrations of aluminum and iron. The crossed information between equilibrium, spectroscopic and molar volume data allowed proposals for the composition of the Pd(II) extracted species until 4.5 M HCl: (L – organic extractants) Thioamides: [PdCl2L2] Thiodiglycolamide: {[PdCl2L2]. ≈ 0.3 LH+ Cl-} 75 76 Solid State Chemistry The main goal of the Solid State Chemistry group is related to the preparation and characterization of environmental / energy / biocompatible materials with high economic and social benefit. Solid State Chemistry Group interests are focused on functional inorganic materials, namely binary and ternary oxides. These materials can be designed, tailoring its properties and improving its functionality through solid state chemistry, solution chemistry, hydrothermal and/or electrochemical synthesis routes. Applications of these materials include: Environment protection – Development of new catalysts for toxic pollutants and pharmaceutical drugs degradation, by means of photocatalysis or photoelectrocatalysis processes. The group combines different materials composition with specific methods of synthesis to design the catalyst surface, which is crucial to improve the catalytic activity. Energy conversion – The manufacture and improvement of photoanodes for dye-sensitised solar cells (DSSC) is an area where the SSC group has been working. The main objective of our work is the enlargement of metal oxide based nanostructures that maximize the electron transport, enhancing the power conversion efficiencies of the DSSC device, using low-cost and soft processing methods. Biomedicine – One of the biomedical applications of magnetic iron oxide nanoparticles is magnetic hyperthermia for cancer therapy, a technique which allows to destroy cancer cells, also increasing the efficiency of chemo- or radiotherapy. Our group is particularly interested in the development of new biocompatible materials with magnetic properties suitable to make them good candidates for magnetic hyperthermia for cancer therapy. http://ssc.ciencias.ulisboa.pt/ 77 Highlight New materials for wastewater treatment Hierarchically grown CaMn3O6 nanorods by RF magnetron sputtering for enhanced visible-lightdriven photocatalysis, B. Barrocas, S. Sério, M. E. Melo Jorge, J Phys Chem C, 2014, 118, 24127−24135. Annealed Ti/Zn-TiO2 nanocomposites tested as photoanodes for the degradation of Ibuprofen, A. Gomes, T. Frade, K. Lobato, M. E. Melo Jorge, M. I. da Silva Pereira, L. Ciriaco, A. Lopes, J. Solid State Electr, 2012, 16, 2061-2069. The removal of organic pollutants and pharmaceutical drugs from wastewater is currently one of the major concerns in environmental control. In order to address these problems, considerable efforts have been devoted to develop techniques more effective than the conventional processes to eliminate these pollutants. Removal of organic pollutants: For the first time the growth of immobilized CaMn3O6 nanorods (NRs) by RF magnetron sputtering onto quartz glass substrates was carried out. It was found that the immobilized CaMn3O6 NRs exhibit much higher photocatalytic activity than the TiO2 films on the degradation of Rh6G under visible light irradiation. This study further revealed that the high catalytic efficiency of CaMn3O6 NRs probably arises as a result of the complex interaction between the double chains of edge-shared MnO6 octahedra, the mixture between Mn3+ and Mn4+, and/or the higher surface-tovolume ratio (surface morphology) afforded by the nanorods geometry, together with a process of dye self-sensitization. Furthermore, it is reported here the importance of this new nanostructured material in obtaining active visible-light photocatalysts. Pharmaceutical drugs degradation: Photoactive annealed Ti/Zn-TiO2 electrodes were successfully prepared and used for the first time on the photoelectrochemical degradation of Ibuprofen. We demonstrated that Ibuprofen was efficiently degraded probably due to high area of the films, as a consequence of their morphology: ZnO needle-shaped grains. 78 Highlight Tailoring one-dimensional nanostructured metal oxides and their application in energy conversion technology 1 m Nucleation and growth of ZnO nanorod arrays onto flexible substrates, D. Siopa, A. Gomes, J. Electrochem. Soc. 2013, 160, D476-484. A possible growth mechanism for ZnO-TiO2 composite nanostructured films prepared by electrodeposition, T. Frade, M. E. Melo Jorge, B. Fernández, R. Pereiro, A. Gomes, J. Electrochem. Soc. 2014, 161, D125-D133. The general use of solar energy harvesting is still limited by two significant challenges, conversion efficiency and cost. Among novel PV technologies, the highest efficiency was attained, up to now, with solid-state perovskite solar cells (PSC) with an overall efficiency of 20 %. The manufacture and improvement of electron-transporting materials for PSC is an important subject which has been developed in recent years by our group, contributing to the progress of new technologies for applications in energy conversion. Our principal aim is to develop metal oxides based nanostructures that maximize the electron transport, enhancing the power conversion efficiencies of the solar cells device, using low-cost and soft processing methods, combining electrochemicalchemical deposition routes. This work is developed in straight collaboration with DEGGE/FCUL, CEFITEC/FCT/UNL and CIDETEC. 79 Highlight Synthesis of magnetic nanoparticles for magnetic hyperthermia Hyperthermia studies of ferrite nanoparticles synthesized in the presence of cotton S.G. Mendo, A. F. Alves, L. P. Ferreira, M.M. Cruz, M.H. Mendonça, M. Godinho and M. Deus Carvalho, New J. Chem., 2015, 39, 7182 – 7193. Magnetic hyperthermia therapy can be a valuable aid in cancer treatment, with less harmful side effects to the patient. It relies on the heat released by magnetic nanoparticles under the influence of an alternate magnetic field. Magnetite (Fe3O4) and maghemite (-Fe2O3) are by far the most explored nanoparticles for hyperthermia applications, but other ferrites, nanocomposites and core@shell structures are also being investigated, in order to improve their ability to act as nanoheaters, making them useful for magnetic hyperthermia. The Solid State Group from CQB, working in straight collaboration with BioISI Biosystems and Integrative Sciences Institute, has been especially involved in the search of new synthesis and processing methods that can improve the magnetic properties of the nanoparticles. We intend to pursue this route since, in spite of the large efforts deployed by various research groups, the thermal efficiency of biocompatible nanoparticles have not yet reached the threshold required to allow regular efficient clinical use of magnetic hyperthermia. 80 Structure and Reactivity The major long term goal of the Structure and Reactivity group (SRG) is the development of rigorous and wellvalidated quantitative structure-property/activity relationships (QSPR/QSAR) to interpret and predict biological and physicochemical phenomena, as well as to assist in the design, synthesis and assessment of new molecules. The group’s expertise in structural characterization of either newly synthesized molecules (designed on the basis of various QSAR methodologies) or of isolated compounds from natural sources (e.g., marine invertebrates from Portuguese exclusive waters), has also been focused on the evaluation of antimicrobial activities, in particular antitubercular activities against wild and resistant strains, or on the identification of new leads to target cancer and Central Nervous System disorders (e.g., IDO, β-amyloid and TAU proteins), within the scope of several collaborations. Also central to the group’s work is the structural and physicochemical characterization of conventional and/or non-conventional solvents and their mixtures, for solvent tuning in dynamic and equilibrium processes, in view of greener future applications in synthetic, separation and/or CO2 capture processes. SRG integrates researchers with diverse backgrounds and skills ranging from Physical to Organic Chemistry. It has a consolidated know-how in spectroscopic characterization, in the study of solute and solvent effects and in the accurate evaluation of kinetic, thermodynamic, interfacial and solvatochromic properties, as well as in the use of statistical and machine learning techniques such as Multiple Linear Regressions and Neural Networks. http://structreact.fc.ul.pt/ 81 Highlight Unraveling antitubercular drug activities using experimental and in silico approaches Molecular details of INH-C10 binding to wt KatG and to its S315T mutant, V. H. Teixeira, C. Ventura, R. Leitão, C. Rafols, E. Bosch, F. Martins, M. Machuqueiro, Mol. Pharmaceutics, 2015, 12, 898. Isoniazid (INH) is still one of the two most effective antitubercular drugs and is part of all recommended multitherapeutic regimens. Due to the increasing resistance of Mycobacterium tuberculosis to INH, new INH-based compounds have been proposed to circumvent this problem. Among the most promising compounds, a new, QSAR-based designed, INH derivative with an alkyl chain in C10 (INH-C10), showed a six-fold increase in activity against a katG S315T mutated strain of Mtb. Continuing our efforts to rationalize this unexpected result, molecular dynamics simulations over wild type and mutated strains were carried out with ITC group, in order to explore the conformational space of both proteins. Also, molecular docking studies were used to determine the preferred modes of binding of the two substrates, INH and INH-C10, with the enzymes. Results showed that the increase in activity of INH-C10 could not be assigned to changes in the steric environment of the access channel to the heme site, since they were found to be negligible, but rather to subtle electrostatic changes in the vicinity of the heme pocket which will influence its reactivity. On the other hand, the C10 chain seems to be able to counterbalance most of the conformational restrictions introduced by the mutation thus leading to an activity enhancement. Further research involving soaking experiments with INH-C10 in KatG, assays to assess the amount of produced free radicals, and computational studies to calculate energy barriers of radical formation are being performed within the scope of a recently set collaboration with Prof. P. Loewen in Canada to try to shed some light into these “drug”target interactions. 82 Highlight Hybrid indoles as antitubercular agents 9 Synthesized cpds Model I Predicted log(1/MIC) 8 7 6 5 4 3 2 2 4 6 8 Observed log(1/MIC) Design, synthesis and biological evaluation of hybrid indoles as potentially new antitubercular agents., A.

Martins., 2016 (submitted) In line with our QSAR-oriented design of new antitubercular compounds, we have pursued with our partners, as foreseen in project PTDC/QUI/67933/2006, our modeling studies of a 4th target family – the indole family. Based on classification and regression models built using Random Forests and Associative Neural Networks, four compounds were actually synthesized and assessed against the H37Rv strain of Mycobacterium tuberculosis (Mtb). One of them ranks among the top range of known antitubercular indole-based derivatives. 83 Highlight Thermodynamic studies of CO2 absorbent solvents C C N Thermodynamics of {water + a new generation sterically hindered amine} for CO2 capture C C C O O Thermodynamic study of aqueous 2-(isopropylamino)ethanol. A sterically hindered new amine absorbent for CO2 capture, I.M.S. Lampreia, Â.F.S. Santos, M.L.C.J. Moita, L.C.S. Nobre, J. Chem.Therm., 2015, 81, 167–176. CO2 emissions generated by fossil fuel combustion are the major source of greenhouse gases. Among the technologies available for CO2 capture, solvent absorption has been the most widely used. Aqueous amines and alkanolamines are important chemicals used by industry for this purpose, as they present low regeneration energy costs. In this respect, a complete thermodynamic characterization of these solvent systems is crucial to gather information on changes in aggregation and hydration patterns which might have an impact on their absorption efficiency. Studies involving e.g., aqueous mixtures of 2isopropylamino)ethanol, a member of a hindered new generation of amine absorbents, have been systematically carried out in different composition ranges and temperatures within the scope of an ongoing collaboration with Centro de Química Estrutural – Ciências. 84 Highlight Other research contributions for the Clean Environment thematic line Enhanced clofibric acid removal by activated carbons: water hardness as a key parameter., A.S. Mestre, A.Nabiço, P.L. Figueiredo, M.L. Pinto, M.S.C.S. Santos, I.M. Fonseca., Chemical Engineering Journal 2016, 286, 538–554. Effects of aggregation in solution have proven to be relevant in the adsorption of various pharmaceuticals. Clofibric acid is a persistent polluent (blood lipid regulator) and its adsorption behavior on activated carbons, depends on carbon textures and water hardness (coordination), a phenomenon which is determinant for sewage plant removal efficiency [1]. This work was carried out in collaboration with the Adsorption and Adsorbent Materials group. The recovery of spent catalytic converters stands as an important milestone for the design of efficient extractants, as well as for the comprehension of the extraction mechanisms, and our collaboration with the Separation, Science & Technology group deals with both these aspects[2]. 85 86 87 88 Publications Synthesis of glucopyranos-6ʹ-yl purine and pyrimidine isonucleosides as potential cholinesterase inhibitors.
