Abstract (sommario):

This thesis describes the results of experiments into the intra and inter-molecular binding of various ligands with dsDNA via the mechanism of intercalation, principally using the technique of atomic force microscopy (AFM). Since the description of the first AFM in the mid 1980’s, AFM has emerged as a sensitive and versatile analytical tool, capable both of detecting and manipulating artefacts at picometer resolutions. In these studies, AFM imaging, supported by circular dichroism, reveals unusual conformational changes in DNA that occur as a result of the binding of ligands that incorporate t

Abstract (sommario):

L’ADN gyrase est une enzyme vitale pour la bactérie grâce à sa capacité de manipuler les molécules d’ADN dans la cellule vivante. Cette capacité fait de l’ADN gyrase une cible idéale pour des composés anti-infectieux. Dans ce travail, l’ADN gyrase a été étudié par des méthodes de modélisatoin moléculaire. Une approche de conception de ligands basée sur la structure a été entreprise sur le sous-domaine N-terminal de 24 kDa de l’ADN gyrase B (domaine GHKL). La flexibilité de deux boucles du site actif du domaine GHKL a été étudiée par des simulations de dynamiques moléculaires en présence de dif

Abstract (sommario):

The binding of 9-hydroxyellipticine (9-OHE), Hocchst-33258 (Hoechst) and trans-bis-(4- N-methylpyridiniumyl)diphenylporphyrin (t-112P) to DNA has been studied by means of spectroscopic techniques. The binding modes of t-H2P to calf thymus DNA (ct-DNA), poly[d(G-C)12 and poly[d(A-T)12 were dependent on ionic strength, ligand load on DNA and the base composition at the binding site. At low ionic strength, flow linear dichroism (LD) data suggested t-H2P binds to ct-DNA and poly[d(A-T)12 in an orientation consistent with groove binding and to poly[d(G-C)12 in an orientation consistent with partial

Abstract (sommario):

Six novel platinum(II) intercalators of the form [Pt(AL)(IL)]Cl2, where AL = ethylenediamine (en), 1R,2R-diaminocyclohexane (R,R-dach), or 1S,2S-diaminocyclohexane (S,S-dach) and IL = 4,7-dihydroxy-1,10-phenanthroline (4,7-dhp) or 4,7-dicarboxy-1,10-phenanthroline (4,7-dcp), were synthesised. All complexes were prepared by the addition of the intercalating ligand followed by the addition of the diamine ancillary ligand. The complexes with 4,7-dhp were soluble in DMSO and were characterised by 1H, 13C, and 195Pt NMR, elemental analysis, UV-vis, ESI-MS, and CD. The complexes with 4,7-dcp were on

Abstract (sommario):

This thesis reports the synthesis and characterisation of two novel metallo-polyamide conjugates; LLSP4-Pt and LLSP4-Ru. Several synthetic strategies were employed in the development of the polyamides, beginning with solution phase chemistry. Construction of the polyamide was attempted via chain elongation with sequential additions of pyrrole monomers, however, solution phase methods were unable to achieve the coupling of four consecutive pyrrole rings. Solid phase chemistry, using a peptide synthesiser, was then used as an alternative. Synthesis using solid phase chemistry required the produc

The dinuclear complex [{trans-PtCl2(NH3)}2-µ-(H2N(CH2)6NH2)]2+ (1,1/t,t) was the first of this series to show promising results, however, it was the trinuclear complex [{trans-PtCl2(NH3)}2-µ-trans-Pt(NH3)2(H2N(CH2)6NH2)2]4+ (1,0,1/t,t,t or BBR3464) that was chosen for clinical trials based on significantly increased cytotoxicity compared to 1,1/t,t and cisplatin.

Ce mécanisme représente une source majeure de chimiorésistance dans certains cancers. Plusieurs études ont ainsi validé la voie BER

The work described in this thesis investigates the mechanisms by which copper complexes catalyse the generation of reactive oxygen species (ROS), including the highly reactive hydroxyl radical (.OH), and induce oxidative damage to DNA.

In contrast, it is suggested that a Cu(III) species may be formed in the reaction of aqueous, unchelated copper ions. The generation of .OH in the copper-Fenton reaction, under biomimetic conditions, was confirmed by analysis of th

Abstract (sommario):

La voie de signalisation du récepteur des androgènes (AR) est impliquée dans la progression du cancer de la prostate, et il a été montré que des mutations dans ce domaine étaient responsables de l'activation constitutive des gènes placés sous le contrôle des hormones androgènes. Une de ces mutations transforme un résidu thréonine du DBD en alanine (T575A). Des expériences permettant de mesurer l'activité de transcription ont permis à l'équipe du Dr. Ceraline à l'IRCAD de montrer que la mutation T575A induit un changement de spécificité du récepteur. Alors que l'activité de promoteurs placés so

Abstract (sommario):

Dans une première partie, nous mesurons l'affinité de l'interaction entre [Ru(pby)2dppz]2+ et l'ADN en utilisant la luminescence induite lors de la complexation. Nous étudions l'évolution de l'affinité lorsque la force ionique de la solution augmente. Dans une deuxième partie, nous modifions les extrémités d'un double brin d'ADN en y greffant des fluorophores. De la mesure de transfert d'énergie non-radiative entre ces fluorophores, nous étudions l'évolution de la longueur du complexe. Nous effectuons un dosage d'un double brin de 15 paires de bases d'ADN par le complexe ruthéné. Nous nous ser

Abstract (sommario):

博士<br>東海大學<br>化學系<br>102<br>The first part of this thesis reports the study of the energetic basis of complex DNA–peptide interactions relating to allosteric interactions. In common with other designed peptides, ten new conjugates incorporating the XPRK or XHypRK motif (Hyp = hydroxyproline) attached to a N-methylpyrrole (Py) tract with a basic tail have been found to display cooperative binding to DNA involving multiple monodentate as well as interstrand bidentate interactions. Quantitative DNase I footprinting show that allosteric communication via cooperative binding to multiple sites on co
