The lysozyme binding affinity of new Au(III) complexes, bearing pyridylbenzimidazole ligands, was studied by ESI-MS and UV/visible. Metalation of lysozyme happened mainly by {Au}n+, {AuCl}0/n+ and {AuCl2}n+/-. The appendage sulfonate group of pyridylbenzimidazole ligand system played a role in determining the products of interaction of HEWL with Au(III) complexes. The hydrophilic sulfonate group inhibited the ligand cleavage via the participation in several coulombic and H-bond interactions giving several AuLn+ containing adduct peaks (L = 1-[(pyridin-2-yl) benzimidazole]-propyl-sulfonic acid). The stability of the complexes in presence of ascorbic acid was examined by UV/visible and 13C NMR. To recognize if His15 side-chain is the metalation site of HEWL, the interactions between the complexes and imidazole, as a simple model of histidine, were studied by 1H and 13C NMR. The DNA binding studies of the complexes are reported. For this class of Au(III) complexes, it is preferred to decorate the pyridylbenzimidazole system with Et group rather than sulfonate and phthalimido group to have a complex with interesting antifungal activity against Candida albicans and Cryptococcus neoformans var. grubii. Au(III) complex, having sulfonate group, is noncytotoxic to non-malignant cells (human embryonic kidney cells (HEK293)), shows negligible Hb release and is safe to the normal cells if applicable. In the experiment, the researchers used many compounds, for example, N-(5-Bromopentyl)phthalimide (cas: 954-81-4Related Products of 954-81-4).
N-(5-Bromopentyl)phthalimide (cas: 954-81-4) belongs to organobromine compounds. Most organobromine compounds, like most organohalide compounds, are relatively nonpolar. The principal reactions for organobromides include dehydrobromination, Grignard reactions, reductive coupling, and nucleophilic substitution.Related Products of 954-81-4
