Photo: CQB day – September 2015

The Centro de Química e Bioquímica was founded in 2001 aiming at creating anenvironment oriented toward fruitful collaborations between chemistry andbiochemistry. The multidisciplinary teams working in the experimental andtheoretical labs within CQB involve approximately sixty PhD members and morethan one hundred collaborators, most of them PhD and Master students. Thelively and youthful atmosphere of the Faculdade de Ciências extends to CQBand is further amplified by the large number of international collaborations andprograms (students from ERASMUS, IAESTE and others).

We conduct fundamental research disseminated by recognized peer-reviewedscientific journals, and the high number of citations reflects its relevance to thescientific community worldwide.

CQB research is organized in two thematic lines, aligned with the SocietalChallenges defined in Horizon 2020 EU, the priorities for the regionaldevelopment of the Lisbon area, and taking advantage of the consolidated skillsof CQB members:

Chemistry and Biochemistry for a Clean Environment

Healthy Life: Molecular Interventions and Regulation Mechanisms

Chemistry and Biochemistry for a Clean Environment

Overview and goals

Chemistry and Biochemistry for a Clean Environment focuses onthe European societal challenges to develop methodologies thatensure a clean and healthy environment. To achieve this, newways of identifying, assessing, preventing, controlling, orefficiently removing contaminants, thereby reducing humanhealth risks, will be addressed. In parallel, we create selective andenvironment friendly catalyst for industrial relevant processes.

CQB has the expertise to synthesize and characterize newmolecules and materials able to degrade contaminants, to adsorbpharmaceutical remains, to obtain heterogeneous andhomogeneous catalysts to improve industrially relevant reactions.

23

Overview and goals

These efforts combined with those purveying analytical methodsdevelopment and biochemists conducting research oriented to theevaluation of their impact on human health will contribute to improvethe cleanliness of the environment.

The support of groups with expertise in computational studies,determination of properties and characterization of molecules andmaterials will significantly improve the knowledge needed to live in aClean Environment, one condition at the heart of the idea of HealthyAgeing!

These potentialities will lead to the creation of environment-friendlyand decontamination technologies, new methods for decontaminationcontrol and residual hazard assessment, and for evaluation of theirimpact on human health.

Adsorption and Adsorbent Materials

The main goal of the Adsorption and Adsorbent Materials(AAM) group is to develop porous materials and exploretheir potentialities as adsorbents, catalysts or catalystssupports or as matrixes for drug delivery systems.Different products are under study, e.g. carbon materialswhich are usually obtained from sub products ofagricultural or industrial activities or by templatemethodologies; natural-clay based solids and metal-organic frameworks. Polyurethane matrixes with differentcompositions, and physical properties (e.g.hydrophobicity), are also developed to be used assupporting adsorbent materials.

Applications of these porous materials include theseparation of alkenes from alkane/alkene mixtures, thepurification (upgrade) of biogas and natural gas byremoving carbon dioxide and nitrogen. Special interest hasbeen given to the use of carbon materials as adsorbentsfor the removal of emergent pollutants (e.g.pharmaceutical compounds) from water.

Additionally, functionalization of porous materials withtransition metal complexes using different methodologiesfor encapsulation is a an hot topic within AAM group. Themain goal is to obtain heterogeneous complexes which arecatalytic active in the homogeneous phase.

Regarding catalysis the group has also interests in themodification of zeolites structures aiming the

improvement of their performance in refining andpetrochemical processes as well as catalysts supports

In the drug delivery systems frame, adsorption and releaseof nitric oxide was evaluated, by storing this compound inporous materials aiming a slow release which could bevery helpful for therapeutic applications.

From biomass to carbon materials to enhance water treatment technologies

Water contamination with pharmaceutical compounds is a reality worldwide andscientists and governmental entities consider that this kind of contamination mayrequire legislative intervention. In fact, pharmaceutical compounds appear in aWatch List in the 2013/39/EU directive and, for now, activated carbons which arenon-specific adsorbents, appear as the best available decontamination technologyfor the removal of the pollutants that have a recalcitrant behaviour in conventionalwater treatment plants.The biomass-derived activated carbons developed in the Adsorption and AdsorbentMaterials group of CQB outperform commercial samples in the ability to removeeven the most recalcitrant pharmaceuticals from water.

Materials for storage and slow release of therapeutic gases

Nitric oxide (NO) is a small endogenous molecule with particularly interesting effectson biological systems, despite its toxicological potential. The delivery of nitric oxide incontrolled amounts to the human body is an attractive therapeutic alternative for alarge number of pathologies. NO is involved in neurological functions in synapticplasticity, neurotransmission, learning, and memory, in addition to having a primaryrole in non-specific immunity and platelet aggregation inhibition.NO is a gas at room temperature and pressure, unlike more common drug moleculesthat are usually in a solid or liquid state. Because of the limited utility of genuine NOgas in many experimental systems and the short half-life of NO in vivo, compoundsthat 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 organconservation.

The main long-term objective of the Environmental andBiological Mass Spectrometry group is to explore thepotentialities of advanced mass spectrometry andspectroscopy in order to investigate at molecular level, thestructure, reactivity and energetics of compounds with,mainly, environmental and biological interest.

Advanced mass spectrometry, ‘Hyphenated’, tandem MS,high resolution (FTICR MS) and spectroscopic techniques,applied to environmental, biochemical/biological,conservation and forensic sciences, enable the structuralcharacterization of compounds, even at trace level, and incomplex matrices (as for example degradation products ofemerging contaminants in the aquatic environment), ofparticular importance to the elucidation of chemical andbiochemical reaction mechanisms and to the developmentof decontamination processes encompassed in thestrategic area entitled Sustainable Chemistry forFunctional Molecules and Materials, defined for CQB.These advanced analytical capabilities are also of majorimportance and a key issue for characterization andproperties evaluation of bioactive molecules that canpotentially contribute for the development of noveltherapeutic agents and medicines and for evaluation ofthe effectiveness and safety of these molecules.

Theoretical methodologies are also applied as a supportfor rationalization of molecular ion structure, mechanismsand gas-phase thermochemistry data.

Cardiovascular diseases are among the highest cause of death in EU includingPortugal. The high cholesterol level in the blood can be mentioned as being amongthe main causes of these diseases. The first and most simple action to reducecholesterol level is to decrease its ingestion in the diet. When this action is notenough, drugs start to be prescribed. Herbal teas, or infusions, used for a wide rangeof purposes can also be used to diminish cholesterol in the blood. Although thesecompounds cannot be sold with claims for health benefits, it is well known that theyare sold and consumed in order to improve people's health. Functional foods, amongwhich are herbal teas, of natural origin, have been the subject of our studies. In ourlaboratory we have long been studying “teas” from plant origin, to determine theircomposition by mass spectrometry techniques and also in what concerns their initialand final biochemical activity after the gastro-intestinal digestion. The results ofthese studies, besides highlighting the components of those mixtures, which isimportant for their quality control, also show that the infusions can have beneficialeffects to health and can be used, for example, for lowering cholesterol in thebloodstream and to facilitate the digestive process.

Enzymes are the core of life. It is our mission to unravelenzyme function and structure, exploring the exquisitecomplexity of life through a systems biology approach. Ourfinal goal is to shape the rules of life to our definedpurposes such as changing enzyme specificity, rewiringpathways and creating novel functional macromolecularstructures.

Our research comprises the role of protein glycation, theglyoxalase pathway and protein-protein interactionnetworks in transthyretin amyloidosis as well as a systemsbiology approach to human infectious diseases, namelyleishmaniasis and pneumococcal diseases. We are seekingenzymes and pathways towards novel therapeuticopportunities 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 asadvanced analytic tools, including FTICR-MS, enablingresearch in metabolomics and proteomics. We arecontinuously improving these tools and expanding thescope of its applications, most notably in the field of massspectrometry, with the development of native MS, top-down proteomics and 2DFTICR-MS.

We spawned and support a biotech start-up, BioMimetx,dedicated to deliver innovative solutions for the control ofbiological proliferation, most notably, biofouling in marineenvironments.

Our group combines complementary experimental andcomputational approaches to chemistry and biochemistry.

We develop new organometallic complexes and materials(porous solids, nanoparticles and ionic liquids) to obtainnew homogeneous and heterogeneous catalysts, aiming atimproving (enantio)selectivity in industrially relevantreactions. We also immobilize bioactive compounds to getnew non-leaching bioactive polymeric materials to protectsurfaces against biofouling. Functional nanomaterials anddevices of magnetic molecules based on spin crossover toprovide polymeric, amphiphilic or nanocrystallineenvironments are being synthesized, as well as materialsfor electrochemical CO2 reduction. Bioactive naturalproducts are isolated in the quest for new drug leads fromPortuguese marine organisms. New psychoactivesubstances marketed as recreational drugs in Portugal areidentified by NMR.

We use Quantum Chemistry to study mechanisms oforganometallic reactions, to calculate the properties ofmolecules and materials in order to improvefunctionalized materials, and to understand in detail theinteractions between bioactive metal complexes andpolyoxometalate derivatives with biomolecules anmaterials. With the help of molecular modeling andsimulation, we are interested in the study of the dynamicproperties of membranes and proteins, their pH-dependence and relation with disease. Additionally, themodeling of non-conventional bonds (such as halogenbonds) in (bio)chemical systems aiming at drug design isalso pursued.

Non-Releasing biocidal coatings: A new strategy for biofouling prevention

Biofouling, a spontaneous colonization of surfaces in contact with water by aquaticorganisms, is a global problem in water management systems of several industrialactivities, and is responsible for serious environmental and economic consequences.For instance, its accumulation on hulls of ships can lead to drag friction increases upto 40 % and subsequent power penalties of up to 86% at cruising speed; whenoccurring in cooling circuits of power plants, it can lead to efficiency losses of about5%. 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 tothe ecotoxicity and cumulative effect of the applied bioactive agents. Therefore, rigidinternational regulations have been issued (BPD EU Regulation, 2012), and more areexpected to come in a near future. New strategies, which can combine moreefficiency against biofouling and non-toxic properties for the aquatic systems, aresought.Our Group developed a new antifouling environmental friendly strategy based on thecovalent bonding of biocides in polymeric coatings (e.g. silicone based). This non-releasing biocide strategy evidenced an effective biocide immobilisation, withpromising coatings’ antifouling performance, up to 6 months to date, on seawatersubmerged coated surfaces with biocidal silicone based coatings.

In the last decade, more than 450 new psychoactive substances (NPS) appeared inthe market of drugs of abuse. The fast dissemination of these new drugs in theinternet created an emerging need for developing new analytical methodologies fortheir rapid identification. Since May 2014, a team of researchers of FCUL, led byHelena Gaspar, researcher at the Centro de Química e Bioquímica, works incollaboration with the Laboratório de Polícia Científica da Polícia Judiciária in theidentification and quantification of NPS in products seized by the Portuguese police.Recently, this team has identified, for the first time in Europe, a new syntheticcathinone, 4F-PBP. The results have already been published in the journal ForensicScience International 2015. This outcome highlights the importance of the academiain supporting the resolution of current problems in our society, as the control of ofNPS’s trade.The work developed by the group of FCUL consists in the isolation and structuralcharacterization of NPS, by means of NMR spectroscopy and Mass Spectrometry,from products supplied by the LPC, or in their synthesis, allowing not only theirtoxicological evaluation, but also the supply of NPS standards to forensic laboratories,to be used in routine analyses.

Compounds identified in seized products in Portugal.

Polylactide (PLA), a biodegradable thermoplastic polyester derived from lactic acid, isa renewable resource, currently attracting attention for applications ranging frombiomedical to food packaging and device applications. It is considered a promisingalternative to petrochemical-based plastics and the fast growth of its productioncapacity (150,000 tons/year currently) suggests it will be a high volume commoditymaterial in the near future. In collaboration with an experimental team, we used acomputational approach to calculate the energy of all the intermediates andtransition states of the full mechanism of the ring opening polymerization (ROP) oflactide catalyzed by a binuclear Zn(II) complex in mild conditions. We identified thedetermining steps and the cooperative role of the two zinc centers. Indeed, detailedknowledge of the reaction will allow the optimization of the process, namelyimproving the catalyst (cheaper, more active), and the reaction (environmentallyfriendlier).

Since the incorporation of cisplatin in chemotherapy, the interest in the application ofmetal systems in medicine has grown rapidly. One step beyond was the incorporationof phenanthroline (phen) ligand in metal complexes, these systems showingsignificant antitumoral activity. Within the interactions of coordination complexeswith DNA, intercalation is an important binding mode and the intercalative capacityof molecules is influenced by the planarity of ligand, type of donor atom, and metalcoordination geometry. Thus the aim of this work was the comprehension andrationalization of the interaction of phen with DNA strands by means ofcomputational techniques. The results showed that intercalation produces importantchanges of geometric parameters of the base pairs. For the systems containingguanine and cytosine, hydrogen bond interactions are more important than stackinginteractions, whereas for the systems with adenine and thymine these stackinginteractions become competitive. Moreover, the contribution of dispersion forces isthe most important contribution to explain the interaction. Nevertheless, thiscontribution is necessary but not sufficient to stabilize the Pauli repulsioncontribution originating between electrons of different fragments having the samespin. Thus, charge transfer contribution (small) and the electrostatic contribution(more important) play an important role to stabilize the intercalator and compensatePauli repulsion. In fact, the values of the electrostatic contribution are roughly similarto the values of the interaction energy.

Biological membranes are complex systems that have recently attracted significantscientific interest. Experimental techniques are very limited in measuring the physico-chemical processes near membranes. On the other hand, computational methods arevery useful since they allow us to study the molecular details of several lipid bilayerdisorders, associated with diseases like the Barth syndrome. The presence of manycharged lipids, render these membranes sensitive to pH. The protonation states oflipids and the ion distribution close to the bilayer are two of the main challenges inbiomolecular simulations of these systems. In this work, we proposed a new methodbased on the Poisson–Boltzmann equation to estimate the ion concentration near alipid bilayer that avoids the need for neutrality at the microscopic level. This newmethodology allows for an increased realism in our molecular simulations and canhave an important contribution in future studies.

Increasing attention has been dedicated to the development of nanomaterialsrendering green and sustainable processes, which avail in benign aqueousreaction media. Nanocatalysts exhibit a significant contact with reactants andallow separation from products, simultaneously achieving the advantages ofheterogeneous and homogenous catalysts. Layered double hydroxide (LDH),which is a family of lamellar metal hydroxides accommodating anions in theirinterlayers, is a promising candidate as a green catalyst. We demonstrate thesynthesis of a family of green nanomaterials, layered double hydroxide (LDH)nanoclusters, which are concentrated (98.7 g/L in aqueous solvent), stablydispersed (transparent sol for >2 weeks), and catalytically-active colloids ofnano LDHs. LDH nanocluster is available as colloidal building blocks to giveaccess to meso/macroporous LDH materials. Thus obtained LDH NC catalyzeKnoevenagel condensation and olefin epoxidation. The catalytic activity iscomparative or higher compared to the cases of using standard LDHs, andrevealed that the LDH nanocluster works as a solid basic catalyst and isseparable from solvents of catalytic reactions, confirming the nature ofnanocatalysts.

Interfacial Electrochemistry

Interfacial Electrochemistry Group research is focused oninterfacial phenomena involving high performancemodified electrodes and semiconductor nanomaterials, todevelop new platforms for (photo)electrocatalytic, energyproduction, (bio)sensing and protective purposes. This isachieved by a careful and precise combination of materials(conducting polymers, self-assembled monolayers andnanostructures) and preparation methods(electrochemical, chemical coupling/adsorption,modification/sensitization).

In catalysis and sensing is extremely advantageous andchallenging to have active centres stably immobilizedpreserving their identity and function. Association ofelectrochemical and surface sensitive characterizationtechniques greatly contributes to elucidate aboutstructure, properties and reactivity relationships. Benefitsarise from the use of functionalized electrodes, sincereactive entities properties can be tailored and modulatedby electric potential application.

Additionally, the materials evaluation in energy productionand environmental remediation processes, are studied inthe IEG group. Another research line, is the evaluation ofthe effect of bioactive chemicals and proteins onbiomimetic supported lipid bilayers, mainly by highresolution imaging.

Electronically conducting polymers (or conducting plastics) are well knownelectrochromic materials. They undergo reversible colour modifications accordingwith the electrical potential they are submitted. On the other hand, somemetalloporphyrins like the iron-porphyrin - that we can find in hemoglobin – are verysensitive to the presence of oxygen, which induces redox transformations in themolecule. Incorporating the iron porphyrin into a polyaniline (conducting polymer)matrix, resulted in a high sensitive oxygen sensor. In a cooperative work of the Centreof Chemistry and Biochemistry from Ciências and the Chinese Academy of Sciences, anovel oxygen sensor for Biochemical Oxygen Demand assessment with dualtransduction was developed. The interaction of the dissolved gas with the porphyrinprovokes a spontaneous adjustment of the intrinsic electric potential of the polymercausing the modification of the optical properties of the material. In this way, boththe electric signal and the optical response of the polymer reflect to the presenceand amount of dissolved oxygen. The optical monitoring of the electrode isperformed by TIRIE (Total Internal Reflection Imaging Ellipsometry) which is atechnique highly sensitive to changes of the dielectric properties of the samples. Thecombined electrochemical and optical signals strongly corroborate each other,allowing the normalization of the readings in repetitive measurements using thesame modified electrode.

The use of nanocrystalline semiconductors as photocatalysts, on the treatment ofindustrial wastewaters, has generated great interest, due to their uniquephysicochemical 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 materialswith new and improved photocatalytic performances. The TNF were produced viahydrothermal 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/TNFnanocomposite materials with different layouts. The samples’ photocatalyticperformance was first evaluated through the production of the hydroxyl radical usingterephthalic acid as model molecule. All the tested samples show photocatalyticability for the production of this oxidizing specie, very important in thephotodegradation of organic pollutants. Afterwards, the samples were investigatedfor the removal of methylene blue. Methylene blue is an industrial dye, used often asmodel pollutant in photocatalytic degradation studies. From the nanomaterialsmaterials studied, the nanocomposites with best adsorption ability were the ZnS/TNFand Bi2S3ZnS/TNF. The most promising results, for the complete pollutant removal,were obtained considering a sequential combination of an adsorption-photocatalyticdegradation process using the Bi2S3ZnS/TNF powder as a highly adsorbent andphotocatalyst material.

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.

The main goal of our group is to advance the state-of-theart of membrane lipid domains, providing means forimproved assessment of their involvement in drugmechanisms of action, pointing directions to develop newdrugs/drug-formulations.

Biological membranes are organized into (micro)domainsconsisting of regions with different lipid and proteincomposition, properties and functions. Furthermore,several pathologies, including cancer andneurodegenerative conditions, are characterized byspecific alterations in lipid composition and hencemembrane biophysical properties. Moreover, themolecular mechanism of action of many drugs involves atsome point their effect on membrane lipid organization(the membrane-lipid therapy principle). Thus,fundamental research on membrane domains in bothphysiological and pathological situations will take place inparallel with the study of compounds that can potentiallypromote health and prevent functional decline.

Several molecular biophysical approaches are used totackle the complex interactions between these agents andbiomembranes, proteins and DNA, with potential benefitsfor society. We use design-and-synthesis approaches todevelop new compounds, bio-inspired and from naturalorigin, namely, essential oils from aromatic and medicinalplants, seeking the valorization of Portugal and CPLPcountries 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).

Dengue has recurrent epidemics in Latin America and occurred recently in CapeVerde and Madeira Island. The lack of anti-viral treatment or vaccine makes thecontrol of mosquito vectors a high option to prevent virus transmission. The use ofplants for insect control has increased worldwide, with particular emphasis on searchof essential oils (EOs) obtained by hydrodistillation.The present study evaluated the potential use of Foeniculum vulgare (fennel) EO inthe control of the dengue vector Aedes aegypti.EOs isolated from fennel aerial parts collected in Cape Verde and from a commercialfennel EO of Portugal were analyzed by NMR, GC and GC-MS. trans-Anethole (32 and30%, respectively), limonene (28 and 18%, respectively) and fenchone (10% in bothcases) were the main compounds identified in the EOs isolated from fennel fromCape Verde and Portugal, respectively.The larvicidal activity of the EOs and its major constituents were evaluated, usingWHO 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 andLC99 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 EOsfrom Cape Verde and Portugal, respectively. Bioassays showed that fennel EOs fromboth countries displayed strong larvicidal effect against Ae. aegypti, the Cape VerdeEO being as active as one of its major constituents, (-)-limonene.These results suggest the potential application of fennel EO as a possible naturallarvicidal for the control of the major dengue mosquito vector.

Biological membranes are generally believed to exist in a fluid regime, where a liquiddisordered (ld) phase with low lipid packing and fast lateral diffusion of moleculescoexists with a liquid ordered (lo) one displaying higher lipid packing and slightlyslower lateral diffusion.In recent years, however, our studies have challenged the dogma that another lipidphase, the gel or solid ordered phase, is not physiologically relevant, due to the veryslow lateral diffusion of its components. We have proved that gel domains arepresent in the plasma membrane of growing yeast cells through the use offluorescent 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 geldomains in biomembranes, we undertook a series of experiments using a commonglycerophosphospholipid, the phosphatidylcholine (POPC) and phytoceramide, thebackbone of the complex sphingolipids found in plants and fungi, also present inseveral human tissues such as skin [2]. Our findings using fluorescent probes andliposome suspensions pointed to the formation of POPC : phytoceramidestoichiometric complexes (with stoichiometries 3:1 and 1:2) that display uniquebiophysical properties [2]. Experiments using atomic force microscopy in supportedlipid bilayers, confocal fluorescence microscopy in giant liposomes and X-rayscattering in multibilayers corroborated the supramolecular organization of the lipidsinto complexes. Interestingly, the fluorescent parameters (anisotropy and lifetimes),exhibited by fluorescent probes in liposome suspensions [2] were identical to theones obtained for living yeast cells [1], which show that the gel domains identified invivo may share important properties with the stoichiometric complexes formed in thePOPC/phytoceramide mixtures.

Recently, our group has contributed with a hypothesis/theory paper, proposing amodel “whereby seeds comprised of oligomerised proteins and/or lipids would serveas crystal nucleation centers for the formation of diverse gel/crystallinenanodomains”, the nanodocks model [3]. Moreover, we presented a book chapter,where the literature reports pointing for the formation of highly ordered lipiddomains in vivo was critically reviewed [4]. The relevance that ordered domains mayplay in the organization and function of biomembranes, and their implication in drugmodes of action, and antidrug mechanisms of resistance, both in infectious agentsand in cancer cells, were discussed.

Molecular Energetics

Understanding the relationships between thermochemicalinformation and the structure and dynamics of moleculesand complex molecular systems (e.g. crystals, living cells)is the main long-term objective of the MolecularEnergetics group.

The thermodynamic stability of molecules, as measured bystandard enthalpies of formation and “bond strengths”,can, for example, be rationalized by investigating therelationships between those properties and bond lengthsand angles, steric and electronic parameters, activationenergies, etc.

The energetics of intermolecular interactions regulatesphenomena such as the dissolution of a solute in a solventand the structural organization of molecules in crystals. Byprobing these interactions it is possible, for example, tounderstand many aspects of polymorphism occurrenceand to elucidate the role of solvents in chemical reactivity.Monitoring the production of heat by living organisms canalso provide important clues about their adaptation toenvironmental changes.

The research carried out at the Molecular Energeticsgroup relies on a variety of experimental techniques, suchas X-ray diffraction, microscopy, reaction and combustioncalorimetry, Calvet-drop microcalorimetry, flow-calorimetry, time-resolved photoacoustic calorimetry,differential scanning calorimetry, thermogravimetry,crystallization reactors, and Fourier transform ioncyclotron resonance mass spectrometry (FT-ICR-MS),along with quantum chemical methods and moleculardynamics simulations.

One of the most interesting features of nanomaterials is the change inproperties that normally accompanies a decrease in particle size. Usingcalorimetric experiments and atom-atom pair potential calculations, we wereable to show, for the first time, that the stability of sodium chloride, the mostabundant salt on earth, considerably decreases (>30%) with the decrease ofthe crystal size up to the single molecule dimension. The decrease isparticularly steep for crystal sizes below 100 nm. The results furthersuggested that the cohesive energy within each crystal layer varies from site tosite, with the energy differences between adjacent sites decreasing on movingfrom the periphery to the centre of the crystal. As expected, the atoms at theoutmost surface layer exhibit the lowest cohesive energies.

The Thermochemistry of Cubane 50 Years after ItsSynthesis: A High- Level Theoretical Study of Cubaneand Its Derivatives, F. Agapito, R.C. Santos, R.M.Borges dos Santos, J.A. Martinho Simões, J Phys ChemA, 2015, 119, 2998-3007.

Cubane is a unique molecule for its extraordinary C8 cage, where all the sp3hybridized carbon atoms have C–C–C bonds angles of 90°. It is therefore one of themost strained compounds known and, until its synthesis in 1964, there was doubtthat such a molecule could even hold together. But cubane turned out to be asurprisingly stable molecule, since no kinetically viable paths exist for its thermaldecomposition. The synthesis of cubane was driven by the curiosity and fascinationof organic chemists in obtaining the molecular equivalent of a platonic solid.Nevertheless, its derivatives have many important potential applications, such as inhigh-energy fuels, explosives and propellants (e.g., octanitrocubane), and as anintermediates in pharmaceutical preparations. Because the cubane frame is rigid,substituents will have precise spatial relationships to each another. This offersfascinating substituent positioning possibilities for the synthesis of novelpharmaceuticals. To assess viable synthetic pathways, knowledge on the energeticsof the cubane molecule and its reactive intermediates is needed. In general, thiskinetic modeling requires “chemical accuracy” of about ±4 kJ mol-1. We used high-accuracy state of the art computational methods to determine the enthalpies offormation of cubane and related compounds.

Redox Biology Group

http://redox.fc.ul.pt/

The Redox Biology group research focuses on hydrogenperoxide (H2O2), the main cellular oxidant now considereda key redox regulator. The long-term goal is to understandsignalling pathways and molecular mechanisms by whichH2O2 regulates physiological processes that, whenunbalanced, lead to disease.

H2O2, is continuously produced intracelullarly, as a by-product of aerobic metabolism, and extracelullarly as aresult of phagocyte activation. Our group uses aninterdisciplinary approach, as the team is composed ofpeople with a strong background in molecular biology, freeradical biochemistry, cell biology and mathematicalmodeling, with a combination of both experimental andmathematical modelling approaches to study cellularredox regulation by hydrogen peroxide and itsinvolvement in physiological cellular processes and indisease.

The group expects to establish quantitative andcause/effect relationships between H2O2 levels andregulation of gene expression, organelle dynamics anddisease. These studies will allow to identify moleculartargets 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 ofemerging contaminants at sub-lethal concentrations. Ourefforts will be focused on the biological adaptationinduced by contaminants. For that we will use our know-how on H2O2 adaptation acquired over the last decade.

Hydrogen peroxide (H2O2), a reactive oxygen species (ROS), is a ubiquitous oxidantpresent in all aerobic organisms. Since its first identification in a living cell, H2O2 wasconsidered a toxic by-product of aerobic metabolism, something that cells had toremove. If H2O2 detoxification catalyzed by catalases and peroxidases was notadequate, H2O2 would diffuse and oxidize biological targets causing cellularmalfunctions, 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 aparadigm where hydrogen peroxide acts in cellular regulation and is involved incellular signalling – redox signalling – through the oxidation of thiols in proteins thatact as redox sensors. Nowadays, redox biology is an established field and theessential regulating role played by H2O2 in vivo with important implications in healthand disease is unquestionable. In this work it was shown that the complexity of redoxregulation increases along the phylogenetic tree and that H2O2 modulates geneexpression at all steps from transcription to protein synthesis. Also, some of theunanswered questions regarding our understanding of redox-dependent regulationof 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 transcriptionfactors?

Separation Science & Technology Group

The Separation Science & Technology (SS&T) group iscomposed by two research laboratories, namely, theChromatography & Capillary Electrophoresis Lab. and theHydrometallurgical Separations Lab. The common goal ofour group is the development of new approaches toimplement chemical separation techniques. The researchwork carried out by our group is based on two differentresearch lines:

The Chromatography and Capillary Electrophoresis line isinvolved on the development of new analyticalmethodologies to monitor trace levels of several classesof emergent compounds (e.g. EDC’s, PPCP’s, POP’s,DBP’s, etc.) from many type of priority matrices. Most ofour analytical work has been focused on theimplementation of novel sorption-based microextractionmethodologies in combination with modern instrumentalsystems, in particular as analytical alternatives tomonitor environmental, pharmaceutical, food, forensicand biological samples.

The Hydrometallurgical Separations line focuses researchon the development and characterization of newfunctional organic molecules to efficiently and selectivelyrecover metal species from feed industrial complexaqueous solutions, and / or effluents. One of the aims isto contribute to the decontamination of theenvironment, through innovative processes for thehydrometallurgical recycling of end-of-life materials, andprofiting from the economic value several metals inindustrial wastes have.

The removal of organic pollutants and pharmaceutical drugs from wastewater iscurrently one of the major concerns in environmental control. In order to addressthese problems, considerable efforts have been devoted to develop techniques moreeffective than the conventional processes to eliminate these pollutants.Removal of organic pollutants:

For the first time the growth of immobilized CaMn3O6 nanorods (NRs) by RFmagnetron sputtering onto quartz glass substrates was carried out. It was found thatthe immobilized CaMn3O6 NRs exhibit much higher photocatalytic activity than theTiO2 films on the degradation of Rh6G under visible light irradiation. This studyfurther revealed that the high catalytic efficiency of CaMn3O6 NRs probably arises asa 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-to-volume ratio (surface morphology) afforded by the nanorods geometry, together witha process of dye self-sensitization. Furthermore, it is reported here the importance ofthis new nanostructured material in obtaining active visible-light photocatalysts.Pharmaceutical drugs degradation:

Photoactive annealed Ti/Zn-TiO2 electrodes were successfully prepared and used forthe first time on the photoelectrochemical degradation of Ibuprofen.

Synthesis of magnetic nanoparticles for magnetic hyperthermia

Magnetic hyperthermia therapy can be a valuable aid in cancer treatment, with lessharmful side effects to the patient. It relies on the heat released by magneticnanoparticles under the influence of an alternate magnetic field. Magnetite (Fe3O4)and maghemite (-Fe2O3) are by far the most explored nanoparticles forhyperthermia applications, but other ferrites, nanocomposites and core@shellstructures are also being investigated, in order to improve their ability to act as nano-heaters, 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 thesearch of new synthesis and processing methods that can improve the magneticproperties of the nanoparticles. We intend to pursue this route since, in spite of thelarge efforts deployed by various research groups, the thermal efficiency ofbiocompatible nanoparticles have not yet reached the threshold required to allowregular efficient clinical use of magnetic hyperthermia.

Structure and Reactivity

The major long term goal of the Structure and Reactivitygroup (SRG) is the development of rigorous and well-validated quantitative structure-property/activityrelationships (QSPR/QSAR) to interpret and predictbiological and physicochemical phenomena, as well as toassist in the design, synthesis and assessment of newmolecules.

The group’s expertise in structural characterization ofeither newly synthesized molecules (designed on the basisof various QSAR methodologies) or of isolated compoundsfrom natural sources (e.g., marine invertebrates fromPortuguese exclusive waters), has also been focusedon the evaluation of antimicrobial activities, in particularantitubercular activities against wild and resistant strains,or on the identification of new leads to target cancer andCentral Nervous System disorders (e.g., IDO, β-amyloidand TAU proteins), within the scope of severalcollaborations.

Also central to the group’s work is the structural andphysicochemical characterization of conventional and/ornon-conventional solvents and their mixtures, for solventtuning in dynamic and equilibrium processes, in view ofgreener future applications in synthetic, separation and/orCO2 capture processes.

SRG integrates researchers with diverse backgrounds andskills ranging from Physical to Organic Chemistry. It has aconsolidated know-how in spectroscopic characterization,in the study of solute and solvent effects and in theaccurate evaluation of kinetic, thermodynamic, interfacialand solvatochromic properties, as well as in the use ofstatistical and machine learning techniques such asMultiple Linear Regressions and Neural Networks.

Isoniazid (INH) is still one of the two most effective antitubercular drugs and is part of allrecommended multitherapeutic regimens. Due to the increasing resistance ofMycobacterium tuberculosis to INH, new INH-based compounds have been proposed tocircumvent this problem. Among the most promising compounds, a new, QSAR-baseddesigned, INH derivative with an alkyl chain in C10 (INH-C10), showed a six-fold increase inactivity against a katG S315T mutated strain of Mtb. Continuing our efforts to rationalize thisunexpected result, molecular dynamics simulations over wild type and mutated strains werecarried 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 ofthe two substrates, INH and INH-C10, with the enzymes. Results showed that the increase inactivity of INH-C10 could not be assigned to changes in the steric environment of the accesschannel to the heme site, since they were found to be negligible, but rather to subtleelectrostatic changes in the vicinity of the heme pocket which will influence its reactivity. Onthe other hand, the C10 chain seems to be able to counterbalance most of theconformational restrictions introduced by the mutation thus leading to an activityenhancement. Further research involving soaking experiments with INH-C10 in KatG, assaysto assess the amount of produced free radicals, and computational studies to calculateenergy barriers of radical formation are being performed within the scope of a recently setcollaboration with Prof. P. Loewen in Canada to try to shed some light into these “drug”-target interactions.

In line with our QSAR-oriented design of new antitubercular compounds, wehave pursued with our partners, as foreseen in project PTDC/QUI/67933/2006,our modeling studies of a 4th target family – the indole family. Based onclassification and regression models built using Random Forests and AssociativeNeural Networks, four compounds were actually synthesized and assessedagainst the H37Rv strain of Mycobacterium tuberculosis (Mtb). One of themranks among the top range of known antitubercular indole-based derivatives.

CO2 emissions generated by fossil fuel combustion are the major source ofgreenhouse gases. Among the technologies available for CO2 capture, solventabsorption has been the most widely used. Aqueous amines and alkanolaminesare important chemicals used by industry for this purpose, as they present lowregeneration energy costs. In this respect, a complete thermodynamiccharacterization of these solvent systems is crucial to gather information onchanges in aggregation and hydration patterns which might have an impact ontheir absorption efficiency. Studies involving e.g., aqueous mixtures of 2-isopropylamino)ethanol, a member of a hindered new generation of amineabsorbents, have been systematically carried out in different compositionranges and temperatures within the scope of an ongoing collaboration withCentro de Química Estrutural – Ciências.
