DNA interactions of new antitumor aminophosphine platinum(II) complexes.

abstract：:Because cytotoxicity by an alkylating agent such as N-methyl-N'-nitrosoguanidine is markedly increased in adenine methylase-deficient dam-3 Escherichia coli, it was of interest to assess whether mismatch repair was similarly important in the repair of DNA damage induced by cis-diamminedichloroplatinum(II) (CDDP).
