Abstract :

We have investigated the cytotoxic activity, the induction of apoptosis, and the interstrand cross-linking efficiency in the A2780cisR ovarian tumor cell line, after replacement of the two NH3 nonleaving groups in trans-[PtCl2(NH3)(2)] (trans-DDP) by dimethylamine and isopropylamine. The data show that trans-[PtCl2(NH(CH3)(2))(NHCH(CH3)(2))] is able to circumvent resistance to cis-[PtCl2(NH3)(2)] (cis-DDP, cisplatin) in A2780cisR cells.
