3-D QSAR studies on new dibenzyltin(IV) anticancer agents by comparative molecular field analysis (CoMFA).
Dibenzyltin(IV)dichloride and dibenzyltin(IV)diisothiocyanate derivatives with N,S-donor ligands show significant cytotoxic activities against human cancer cell lines, and are well compared to analogous dialkyltin(IV) derivatives. CoMFA models were generated for the first time for these organotin derivatives using the cytotoxic activities (against two human tumor cell lines, MCF-7, a mammary carcinoma and WiDr, a colon carcinoma) of 21 complexes. High r(2) and r(2)(cv) values for both CoMFA models indicate good predictive power for the models.
