Abstract (sommario):

The general aim of the project is predict and select small molecule ligands which may bind to 3D protein templates. Proteins from the Immunophilin family were used. The putative ligands were selected by two different methods, by structure similarity and using the docking program LIDAEUS, which was developed in house by Dr. P. Taylor. Twenty nine small molecules were selected from a small molecule database and were tested with a fluorescence assay, a PPIase assay and x-ray crystallography for binding activity. Six new ligands have been discovered which bind to Cyp-A. In this work the IC<sub>50<

The known ruthenium pincer complex RuCl(eta3-dcpx)(PPh 3) (7) (PCP = eta3-2,6-(PCy2CH 2)2C6H3) was transformed into several different hydride products under standard transfer hydrogenation conditions. In situ 31P NMR analysis during thermolysis of 7 in basic isopropanol permitted identification of RuH(eta3-dcpx)(PPh 3)(N2) (8a/b), RuH(eta3-dcpx)(PPh 3) (10), and RuH(eta3-dcpx)(PPh3 )(H2) (9a/b).

Strong and selective binding to iron(III) oxide/hydroxide surfaces, e.g. goethite, over unwanted silicaceous material was considered essential criteria for such new cocollectors.

Abstract (sommario):

Elastase is irreversibly inhibited by compounds incorporating a β-lactam ring and this thesis describes structural studies on three classes of β-lactam inhibitor. The mechanism of inhibition begins with nucleophilic attack by the catalytic serine on the carbonyl which is at position 2 of all the β-lactams. In all cases this results in the opening of the ring between position one and two and the departure of the position four substituents. X-ray crystal structures and mass spectra obtained of elastase in complex with each of the ligands described the bound products of each reaction. β-lactams h

For the purpose of incorporating indoles into organometallic complexes for catalysis, as well as in the generation of new heterocyclic systems, various reactions have been carried out at C2, C6 and C7 of the indole system. In order to achieve this, 3-substituted 4,6-dimethoxyindoles and 6-hydroxy- 4-methoxyindoles were necessary as starting materials. Consequently, a lithium-bromide-templated one-pot procedure for the synthesis of some 3-substituted 4,6-dimethoxyindoles and a selective demethylation procedure for 3-substituted 6-hydroxy-4-methoxyindoles were developed.

Given that the former can be formed by the reductive elimination of Cp*H from Cp*2AlH, a process common to transition metals yet rare with light main-group elements, using the Cp* ligand could unlock an abundance of unexpected reactivity for aluminium.

Computational methods have been extensively developed at various levels of approximation in recent years to model biomolecular interactions and for rational drug design.

Most characterised protein-small molecule interactions that display a change in heat capacity (\bigtriangleupCp) occur with a negative \bigtriangleupCp value.

Positive \bigtriangleupCp values have not been widely reported and could typically be attributed to an increased solvent accessible apolar surface area, desolvation of polar surface area or structural transitions in the biomolecular complex.

Abstract (sommario):

Molecular simulations approaches are powerful tools for structural biology and drug discovery. They provide additional and complementary information on structure, dynamics and energetics of biomolecules whose structures have been determined experimentally [1,2,3,4,5,6,7]. In particular, Molecular Dynamics (MD) simulations [8], along with elastic network analysis [9], offer insights into molecular fluctuations, conformational changes and allosteric mechanisms. In addition, molecular simulation can be used to design novel and potent ligands to a specific target (either a protein or DNA) as well

Abstract (sommario):

Ligand design in general enables the formation of coordination compounds with multiple functionalities within a single framework. To date, two of the most widely studied ligands are 2,2′:6′,2′′-terpyridine (terpy) and acetylacetone (acac), whose tridentate and bidentate coordination pockets, respectively, enables the formation of metallic complexes with various geometries. The Brusso group had been incorporating imidoyl amidine (ImAm) ligands to build different materials such as organic radicals and fluorescent materials. In particular, the ligands N-2-pyridylimidoyl-2-pyridylamidine (Py2ImAm)

Abstract (sommario):

Nous proposons un ensemble de méthodes pour la conception de systèmes moléculaires. Notre stratégie consiste à utiliser comme modèle des machines naturellement optimisées, les protéines. Les protéines peuvent être des briques structurales, des transporteurs d'informations ou des catalyseurs chimiques. Nous utilisons ici des approches computationnelles, complémentaires aux voies expérimentales, pour concevoir de tels systèmes.Nous avons d'abord entièrement redessiné un domaine PDZ impliqué dans des voies métaboliques. Nous utilisons une approche physics-based basée sur la mécanique moléculaire,
