Cytotoxicity and antitumor activity of bis(platinum) complexes. A novel class of platinum complexes active in cell lines resistant to both cisplatin and 1,2-diaminocyclohexane complexes.

The in vitro cytotoxicity and in vivo antitumor activity of bis(platinum) complexes of general formula [(PtX2-(L))2H2N(CH2)nNH2] (L = NH3, X = Cl or X2 = malonato or where L = py, X = Cl) is reported. Chloride complexes [(PtCl2(NH3]2H2N(CH2)nNH2] may exist as three possible isomers: those containing both coordination units in the cis configuration (2,2/c,c), both coordination units in the trans configuration (2,2/t,t), and the mixed cis,trans species (2,2/c,t), whose synthesis is reported here. The preparation of further complexes with sterically hindered diamine backbones, such as 2,5-dimethyl-2,5-hexanediamine, is exemplified. The biological activity of all complexes were compared. The 2,2/c,c complexes are particularly active in tissue culture in cells resistant both to cisplatin and its 1,2-diaminocyclohexane (dach) analogue. The inhibition of DNA synthesis in L1210/0 cells by the 2,2/c,c complexes is equivalent to that of cisplatin. The presence of at least one cis-[Pt(amine)2] unit appears necessary for activity in cell lines sensitive to cisplatin.[1]
