Structure-activity relationships of new Organotin(IV) anticancer agents and their cytotoxicity profile on HL-60, MCF-7 and HeLa human cancer cell lines

There is a growing interest in the cancer cell growth inhibitory effects of organotin (IV) compounds and, accordingly, a new series of dimethyl-, di-(n-butyl)-, diphenyl- and chloro-phenyl tin(IV) complexes with a Schiff base core were prepared. Their binding to DNA was assessed by UV thermal denaturation showing no interaction and by UV-vis titration exhibiting moderate interaction by intercalation. Complexes having n-butyl substituents were...
