In order to find correlations between chemical reactivity and biological activity, we have started an investigation on the mutagenic activity of different platinum-chloro-amine complexes towards different strains of Salmonella Typhimurium. The first class of compounds examined includes complexes of general formula cis-[PtCI2(amine)(L)] in which L represents a strong frmw-Iabilizing ligand. Using dimethylsulphoxide as solvent these compounds were not toxic or mutagenic, on the contrary in acetone they were toxic towards all strains of bacteria independently from their excision-repair ability. An entirely different behaviour was exhibited by a second class of compounds having general formula cis-[PtCl2(amine)2] which includes also cis-dichlorodi-ammoniaplatinum(ll) (ds-DDP). These compounds were much less toxic than the previous ones in acetone and were mutagenic; moreover they were able to discriminate between different bacteria strains. Therefore some complexes were active only towards hisG46/pKM101 strain, others towards both hisG46/pKM101 and hisD3052/pKM101 bacteria. Furthermore some compounds (particularly those with H2N-But and H2NCHMePh), differently from ds-DDP, were mutagenic only towards excision-repair deficient strains indicating that they can cause only a specific and well reparable damage.
