Abstract:
As the inhibitory γ-aminobutyric acid–ergic (GABAergic) transmission has a pivotal role in the central nervous system (CNS) and defective forms of its synapses are associated with serious neurological disorders, numerous versions of caged GABA and, more recently, photoswitchable ligands have been developed to investigate such transmission. While the complementary nature of these probes is evident, the mechanisms by which the GABA receptors can be photocontrolled have not been fully exploited. In fact, the ultimate need for specificity is critical for the proper synaptic exploration. No caged allosteric modulators of the GABAA receptor have been reported so far; to introduce such an investigational approach, we exploited the structural motifs of the benzodiazepinic scaffold to develop a photocaged version of diazepam (CD) that was tested on basolateral amygdala (BLa) pyramidal cells in mouse brain slices. CD is devoid of any intrinsic activity toward the GABAA receptor before irradiation. Importantly, CD is a photoreleasable GABAA receptor-positive allosteric modulator that offers a different probing mechanism compared to caged GABA and photoswitchable ligands. CD potentiates the inhibitory signaling by prolonging the decay time of postsynaptic GABAergic currents upon photoactivation. Additionally, no effect on presynaptic GABA release was recorded. We developed a photochemical technology to individually study the GABAA receptor, which specifically expands the toolbox available to study GABAergic synapses.

The crystallographically centrosymmetric zwitterion bis[tris(3,5-dimethyl-2-oxidobenzyl-κO)ammonium]zirconium(IV) crystallizes as the chloroform disolvate, [Zr(C27H31NO3)2]·2CHCl3, with the two molecules of chloroform closely associated with two of the aromatic rings. The Zr atom has a distorted octahedral geometry with three phenoxy O atoms from each of the two ligands coordinated to it. Charge balance is maintained by protonation of each N atom, which then forms intramolecular hydrogen-bonding interactions to all three adjacent O atoms.

Abstract:
The binding of CO to the murine inducible nitric oxide synthase (iNOS) oxygenase domain has been studied by laser flash photolysis. The effect of the (6R)-5,6,7,8-tetrahydro-l-biopterin (BH4) cofactor l-arginine and several Type I l-arginine analogues/ligands on the rates of CO rebinding has been evaluated. The presence of BH4 in the iNOS active site has little effect on the rebinding of protein-caged haem–CO pairs (geminate recombination), but decreases the bimolecular association rates 2-fold. Addition of l-arginine to the BH4-bound complex completely abolishes geminate recombination and results in a further 80-fold decrease in the overall rate of bimolecular association. Three of the Type I ligands, S-ethylisothiourea, l-canavanine and 2,5-lutidine, displaced the CO from the haem iron upon addition to the iNOS oxygenase domain. The Type I ligands significantly decreased the rate of bimolecular binding of CO to the haem iron after photolysis. Most of these ligands also completely abolished geminate recombination. These results are consistent with a relatively open distal pocket that allows CO to bind unhindered in the active site of murine iNOS in the absence of l-arginine or BH4. In the presence of BH4 and l-arginine, however, the enzyme adopts a more closed structure that can greatly reduce ligand access to the haem iron. These observations are discussed in terms of the known structure of iNOS haem domain and solution studies of ligand binding in iNOS and neuronal NOS isoenzymes.

Abstract:
Delivery agents which can carry the {Ru(NO)}6 chromophore (“caged NO”) are desired for vasodilation and for photodynamic therapy of tumors. Toward these goals, complexes derived from [RuCl3(NO)(H2O)2]= (1) have been prepared using dipyridylamine (dpaH) as mono and bis adducts, [Ru(NO)Cl3(dpaH)] = (2) and [Ru(NO)Cl(dpaH)2]Cl2 = (3). The dpaH ligands coordinate cis to the Ru(NO) axis.The mono derivative is a model for a potential DNA groove-spanning binuclear complex {[Ru(NO)Cl3]2(tpada)} = (4) which has two DNA-coordinating RuII centers, photo-labile {Ru(NO)}6 sites, and a groove-spanning tether moiety.The binuclear assembly is prepared from the tethered dipyridylamine ligand N,N,N',N'-tetrakis(2-pyridylmethyl)adipamide (tpada) which has recently been shown to provide a binuclear carrier complex suited to transporting RuII and PdII agents. A related complex, [Ru(NO)Cl(pida)] = (5) with the {Ru(NO)}6 moiety bound to (2-pyridylmethyl) iminodiacetate (pida2-) is also characterized as a potential “caged NO” carrier. Structural information concerning the placement of the pyridyl donor groups relative to the {Ru(NO)}6 unit has been obtained from H1 and C13 NMR and infrared methods, noting that a pyridyl donor trans to NO+ causes “trans strengthening” of this ligand for [Ru(NO)Cl(pida)], whereas placement of pyridyl groups cis to NO+ causes a weakening of the N-O bond and a lower NO stretching frequency in the dpa-based complexes.

Abstract:
L’objectif de ces travaux de thèse est le développement de nouveaux ligand-cages hémicryptophanes pour l’obtention de catalyseurs métalliques confinés. Ces catalyseurs seront utilisés pour l’activation bioinspirée d’O2 et la fonctionnalisation C-H en milieu confiné. Le design des cages cibles vise à introduire des ligands bioinspirés pour la coordination de métaux biologiques (Cu, Fe, Zn). La structure hémicryptophane offre une cavité hydrophobe au voisinage du site actif métallique. Cette structure vise à stabiliser les espèces actives et obtenir des réactivités différentes de celles obtenues avec les modèles ouverts correspondants. Dans ce contexte, l’objectif principale de ce travail a été d’obtenir des complexes de cuivre confinés capable d’activer l’oxygène moléculaire pour accomplir des réactions difficiles de fonctionnalisation C-H. La première partie de cette thèse consiste en étude bibliographique de (i) les précédentes applications des hémicryptophanes et (ii) les progrès récents sur les complexes bioinspirés encagés. Ensuite, nos complexes de cuivres à ligands tris(pyridyl)amine (TPA) ouverts et encagés, ont été étudiés pour l’activation d’O2 et pour des réactions non-usuelle de fonctionalisation de liaisons C-H. Nous avons ensuite préparé et étudié une nouvelle cage TPA-hemicryptophane équipée d’une cavité donneuse de liaisons hydrogène C(triazole)-H. Cette cavité fonctionnalisée vise à reproduire les cavités des métalloprotéines. Enfin, des hémicryptophanes basés sur le ligand triazacyclononane (TACN), ont été préparé pour la première fois. L’objectif de ces nouveaux ligand-cages est de contribuer au développement de complexes bioinspirés à Cu et Fe pouvant, par exemple, activer O2
This thesis aims at developing new hemicryptophane cage-ligands to obtain confined metal-based catalysts for bioinspired O2 activation and C-H bond functionalization in confined space. The design of the targeted cages aims at introducing ligands inspired from metalloproteins active sites, for coordination of biorelevant metals (Cu, Fe, Zn). Importantly, the hemicryptophane structure provide a hydrophobic cavity around the active metal core. This structure aims at stabilizing highly reactive intermediates and reaching different reactivity compare to open model complexes, devoid of cavity. In this context, a major objective of this work was to reach Cu-based bioinspired catalysts able to activate molecular oxygen for challenging C-H bond functionalization. The first part of the thesis consists in a comprehensive literature survey on (i) background of previous applications of hemicryptophane cages and (ii) recent advances in caged bioinspired complexes. The application of our open and caged Cu-complex, based on the tris(pyridyl)amine (TPA) ligand is next described. These catalysts have been used for O2 activation and unusual intramolecular C-H bond functionalization. We then prepare and studied a new TPA-hemicryptophane cage equipped with a C(triazole)-H hydrogen bonding cavity. This functionalized cavity aims at reproducing the binding cavities found in metalloproteins. Finally, hemicryptophane cages based on the triazacyclononane (TACN) ligand have been prepared for the first time. The goal of these cage-ligands is to develop new bioinspired Cu and Fe complexes that could be, for instance, used as O2 activating catalysts

Abstract:
Cells rely on time-dependent binding and activation by the ECM to initiate downstream signal transduction. It is unknown whether adhesion to a ligand is required throughout various cell processes, or only during a specified time period ("temporal threshold”). Current approaches to ligand presentation often comprise of static, constant densities of ligands. In contrast, natural cell adhesive interactions with ECMs exhibit spatiotemporal patterns of binding and activation. Therefore, a key to future research in controlling cell-material interactions will be the development of materials that can respond to external stimuli. The objective of this project is to engineer biomaterials that present a UV-labile caged-Arginine-Glycine-Aspartic Acid (RGD) ligand and evaluate the effects on cell activities. RGD is the minimal adhesive sequence of fibronectin. By dynamically modulating adhesive ligand presentation, the effects of temporal control on cell processes can be elucidated. In this caged-peptide, a photo-labile group adjacent to the aspartic acid residue of RGD effectively “masks” a cyclo(RGDfk) peptide. Upon UV irradiation (360 nm), the caging group is released thereby restoring the adhesive activity of the peptide. By having unparalleled spatiotemporal control of RGD ligand presentation, we demonstrated two novel tools for discovery: 1) in vivo ligand presentation to probe downstream tissue behavior and cell infiltration to biomaterial implants, and 2) in vitro ligand presentation in situ using confocal-based live cell microscopy to investigate real-time vinculin recruitment and cell traction force generation. These studies represented the first demonstration of triggerable adhesive ligand presentation in vivo and demonstrated the utility of caged-compounds for probing specific receptor-ligand responses on highly defined PEG-based hydrogels. Triggerable in vitro ligand presentation, combined with traction force microscopy, demonstrated a new research tool for investigating focal adhesion formation and downstream force generation. Taken in whole, these results provide previously unknown insights into the importance of spatiotemporal control of adhesive ligands and created novel new research platforms for future discovery.

Abstract:
This thesis details the synthesis and coordination chemistry of twenty-five nitrogencontaining heterocyclic ligands, nineteen of which were previously unreported compounds. These ligands were designed for use as synthons for the formation of molecular cages, so contain multiple coordination sites capable of bridging multiple metal atoms. The majority of molecular cages in the literature are formed by rigid bridging ligands, whereas the ligands studied in this research incorporate a higher level of flexibility, thereby lessening the degree of control over the self-assembly process and increasing the number of possible structures that can be formed upon reaction of these ligands with meal salts. Three of the new ligands synthesised were two-armed bridging ligands, which were reacted with a wide variety of metal salts to investigate what self-assembly products were formed. The complexes characterised include a M₃L₃ cyclic trimer, a range of coordination polymers of varying dimensionality, a range of dimeric products and a series of M₄L₆ cage-like molecular squares. However, the majority of ligands studied were three-armed, potentially tripodal compounds, which were envisaged as potential components of M₃L₂ or M₆L₄ molecular cages. The products of self-assembly of these ligands with various metals salts were shown to include a variety of discrete tri- and tetranuclear complexes, a range of coordination polymers of varying dimensionality and interpenetration, and a complex M₆L₄ assembly that appears to be a collapsed coordination cage. Unfortunately some of the ligands synthesised were shown to decompose in the presence of various metal salts, a phenomenon already identified in the literature. Analogues of these decomposition products were synthesised deliberately to identify the potential of a known tridentate ligand as a metallosupramolecular synthon. ¹H NMR spectroscopy, mass spectrometry, elemental analysis, thermogravimetric analysis and X-ray crystallography were used to study the compounds synthesised. The crystal structures of five ligands and fifty-one complexes are discussed.

Ce travail porte sur les complexes des métaux de transitions pour la catalyse de la réduction des protons en hydrogène. La nature de l'espèce catalytiquement active mise en jeu lors du processus de réduction a été étudiée par voltampérométrie cyclique afin de comprendre le rôle et le mode d'action de ces complexes. Le premier chapitre introduit le contexte et les principaux objectifs de ce travail. Le deuxième chapitre propose une étude électochimique de complexes de cobalt et de nickel à ligands bis(glyoxime) et clathrochélates en phase homogène. Leur comportement en présence d'acide et en condition réductrice est décrit et un mécanisme réactionnel associé est proposé. L'influence des ligands de la sphère de coordination sur le comportement électrochimique de ces complexes a été rationalisé par le biais de substitution des groupements présents sur les ligands bis(glyoxime) et clathrochélates. Le troisième chapitre aborde le rôle de pré-catalyseur que peuvent tenir ces complexes en condition d'électrolyse réductrice et en milieu acide. L'électrosynthèse de nanoparticules catalytiques à partir de ces complexes a mis en évidence le rôle majeur des ligands bis(glyoxime) et clathrochélates dans ce phénomène d'électrodéposition. Ces résultats montrent que ces ligands peuvent être utilisés pour contrôler la nature et l'activité de nanoparticules catalytiques pour la réduction des protons en dihydrogène. Le quatrième chapitre vise à immobiliser les complexes de cobalt à ligand clathrochélate au sein de réseaux de coordination afin d'optimiser leur activité catalytique. Malgré la faible solubilité et l'encombrement stérique de ces complexes, des synthèses en conditions très douces ont abouti à la formation de réseaux mono et bi-dimensionels à base d'ions cadmium(II).

Abstract:
[Truncated abstract] Chapter 1 provides an introduction to the 'sarcophagine' class of ligands and the field of metallopolymers. The synthesis, stereochemistry, physical properties and functionalisation of 'sarcophagines' and their metal complexes are discussed. A brief overview of the burgeoning field of metallopolymers is given with specific mention of the synthetic routes to pendant metallopolymers, and how these could be employed to prepared cage amine containing metallopolymers. Chapter 2 deals with the synthesis, characterisation and reactivity of cinnamylamino and styrylamido derivatives of the cage amines [Co((NH2)2sar)]3+, [Co((CH3)(NH2)sar)]3+ and [Cu((NH2)2sar)]2+. The cinnamylamino derivatives were prepared using reductive alkylation of the aforementioned amines with cinnamaldehyde. Procedures were developed to isolate the complexes without causing unwanted additions to the double bond. The cinnamylamino derivatives displayed unexpected reactivity towards a range of reducing agents, resulting in unexpected reduction of the double bond and cleavage of the cinnamyl group, but ultimately in the preparation of phenylpropylamino derivatives of [Co((NH2)2sar)]3+ and [Co((CH3)(NH2)sar)]3+. Attempts to rationalise the reactivity of the double bond have been explored based upon the physical properties and reactivity of the double bond. The styrylamido derivatives were prepared by treatment of the cage amines with 4-vinylbenzoyl chloride, and the complexes isolated in a similar manner to those of the cinnamylamino derivatives to ensure the amide linkage remained intact. Most of the complexes have been structurally characterised. ... Both the 2-thienyl and 3-thienyl derivatives of [Co((NH2)2sar)]3+ and [Co((CH3)(NH2)sar)]3+ have been prepared using reductive alkylation with the respective carboxaldehydes of thiophene. One of the optically pure isomers has been prepared. The complexes have been fully characterised including structural characterisation. Polymerisation of the thiophene-cage amine complexes was investigated under a range of chemical and electrochemical conditions, though polymerisation was never observed. Cleavage of the thienyl groups was observed when ceric ammonium nitrate in nitric acid was used as the oxidant. The attachment of oligothiophenes and mixed pyrrole-thiophene oligomers to cage amines were investigated using reductive alkylation and various pyrrole ring-forming reactions about the apical amino groups, though none of the desired complexes were isolated, reasons for the lack of reactivity were discussed. An efficient synthesis of N-(4-benzoic acid)- 2,5-di(2-thienyl)pyrrole was developed and was shown to the electropolymerisable, albeit the polymer films were non-conducting. Attempts to couple N-(4-benzoic acid)- 2,5-di(2-thienyl)pyrrole with a cage amine via its acid chloride were complicated by decomposition reactions, the nature of one of these products is discussed. Chapter 5 presents investigations into the preparation of simple complexes containing multiple cage amines using alkylation and acylation procedures with aromatic substrates. The complexes were found to exhibit some interesting electrochemical and chemical properties, demonstrating that even simple multiple cage amine species can display complicated and interesting behaviour.

Abstract:
Ce @ travail est consacré à l'association d'une propriété de complexation sélective et d'une propriété tensioactive au sein d'une même molécule. Nous cherchons à moduler et à contrôler chacune des ces deux propriétés indépendamment l'une de l'autre. L'approche utilisée est la synthèse de molécules dibloc : Les molécules cages tensioactives développées résultent du greffage covalent d'un ou plusieurs motifs tensioactifs glucosyles sur un composé macro cyclique ether-couronne azote. Deux molécules cages tensioactives ont été étudiées. Elles diffèrent par le nombre de motifs tensioactifs greffes. Leurs propriétés de complexation vis-à-vis des ions na + et k + ont été mises en évidence par spectrométrie de masse. Nous avons caractérisé les micelles formées par ces différents tensioactifs par ajustements simultanés des spectres de diffusion de rayons-x et de neutrons aux petits angles. Lorsque la longueur de sa chaîne aliphatique croit, le motif tensioactif forme des agrégats ellipsoi͏̈daux puis cylindriques et enfin des bicouches. Les molécules cages tensioactives forment par contre des micelles ellipsoi͏̈dales. Ces micelles sont très peu modifiées lorsqu'un cation est complexe par le macro cycle et semblent peu dissociées de leurs contre-ions. Leur forme et leur taille sont contrôlées par des contraintes stériques, imposées par la nature et le nombre de motifs tensioactifs ainsi que par le macro cycle. Enfin, un montage de flottation ionique a été réalisé à une échelle adaptée à une faible quantité de produit. La technique de flottation consiste à faire mousser un tensioactif dans une colonne. Elle permet d'étudier les équilibres d'adsorption d'ions à une interface eau/air recouverte d'un tensioactif. Il peut s'agir de l'adsorption de contre-ions d'un tensioactif ionique ou également de la complexation du cation par un ligand macro cyclique situe à l'interface. Nous avons alors appliqué cette technique à une molécule cage tensioactive pour évaluer ses propriétés extractantes.

Abstract:
This chapter has targeted the features of inorganic cage compounds, their classification, and their overabundant applications. The term ‘Cage’ is utilized as a specific term for three-dimensional structures which have a definite and rigid geometry. There can be various atomic positions in the cage, these positions can operate as branching origins and additional ligands can be introduced at these positions. Recent advances in the synthetic chemistry and strategies adopted for the synthesis of cage compounds with special attention to Calixarenes and Cryptophanes have played an analytical role in the development of Biomedical Applications, drug freightage systems, sensing, bio-imaging, and other smart materials. The adsorption of dye from industrial wastewater by the functionalized Calixarene cage e.g. Dinitro Calix [4] arene cage (DNCC) was tested for the first time [1]. Recent research indicates that Cryptophane cages can also adopt different configurations and demonstrate various applications [2]. During the 1970s, a founding work by Corbett and Simon on rare-earth halides led to the establishment of the fact that these highly cluster skeleton electron-deficient clusters always involve an interstitial atom inside the metal cluster cage. A novel development in the field of coordination chemistry of integral cage molecules and their ligand complexes has been extensively researched for their budding application as building blocks in polymers [3]. Caged structure complexes, one of its kind in supramolecular chemistry have always garnered the attention of the scientific community worldwide. This book chapter is an initiative to instill the essence of the caged compound with its striking features and a plethora of applications.

Abstract:
This chapter discusses clusters that contain higher oxidation state metals from the early to mid d-block metals with π-donor ligands, focusing on metal halide clusters and their derivatives. It considers three cluster cores or metal centres in a closed framework: triangle, square-based pyramid, and octahedron. It cites an example of a semi-interstitial atom that is partially surrounded by metal centres and is rather exposed. The chapter describes the structural features common to niobium and tantalum halide clusters. These generally consist of an octahedral metal core supported by edge-bridging and terminal ligands. It reviews the crucial role of an interstitial atom as it provides valence electrons for the stabilization of an electron-poor compound from within the cage without imposing steric demands among the ligands around the outside of the cage.

Abstract:
Em 1961, convidado a participar de uma publicação coletiva em homenagem a John Cage, o artista Robert Morris escreveu um texto intitulado Blank Form. Breve, enigmático e sarcástico, esse texto revela, porém, a referência a um terceiro artista, Marcel Duchamp, central para a conformação da cena vanguardista nova-iorquina em que se deram as trocas entre Morris e Cage. Neste artigo pretendemos refletir sobre o conceito de blank form introduzido por Morris, buscando entendê-lo do ponto de vista de uma recepção específica da obra de Duchamp, através do qual Morris deflagrava o que se constituiria a seguir numa estética minimalista. Propomo-nos a pensar blank form como um conceito operativo de uma certa leitura minimalista de Duchamp, ligada à construção histórica deste artista pela geração dos anos 1960 nos Estados Unidos. Ao apresentar e comentar tal conceito – que poderíamos traduzir livremente por forma vazia, branca, neutra ou inexpressiva –, Morris sugere questões que nos parecem cruciais para a identificação do que se convencionou chamar de Duchamp effect na arte contemporânea, especialmente o particular viés cético, até solipsista, enfatizado sob as óticas minimal e pop. Assim, podemos indicar no texto de Morris um desvio da leitura cageana de Duchamp, vigente à época sobretudo através dos happenings e event scores de artistas como Allan Kaprow e George Maciunas, e a produção de uma outra leitura, um novo registro para duas importantes premissas duchampianas: a indiferença do artista e a arte-como-recepção. Esse novo registro da blank form nos ajudaria a compreender a emergência de obras tão distintas quanto as de Robert Morris e Andy Warhol.
