Webfavors cisplatin cross-linking (20) with inter- and intra-DNA strands (14,17,26). Cisplatin interacts primarily with cytosine- and guanine-rich DNA regions (29) and causes cellular damage. Despite its potent antineoplastic action, cisplatin’s major side effects include nephrotoxicity (2), peripheral neuropathy (33), azoospermia (11). In mammals, WebFeb 21, 2000 · Most simple cis-PtA2G2 complexes that model the G-G cross-link DNA lesions caused by the clinically used anticancer drug cis-PtCl2 (NH3)2 undergo large fluxional motions at a rapid rate (A2 = two amines or a diamine; G = guanine derivative). long valley peony farm

WebThe DNA binding is similar to cisplatin, and the complex forms a highly stereoselective adduct on DNA, but not for reactions with mono- and dinucleotides. 98 In cell lines with previously determined mechanisms of cell resistance, AMD473 showed little cross-resistance compared with cisplatin or carboplatin. WebFeb 28, 2024 · Indeed, while cisplatin probably undergoes an efflux effect, compound 19 shows a time-dependent accumulation in cells and a greater ability to cross the membrane. DNA interaction has been confirmed for both complexes due to the presence of the triphenylphosphine hydrophobic moiety and the trans geometry of bromide groups.
