Pt(IV) complexes must be reduced to kill cancer cells. While reduction rates correlate with reduction potentials, we wanted to check if the rates of reduction depend on the cell line used. The reduction of cis,trans,cis-PtCl2(OCOCH3)2(NH3)2 by extracts of three cell lines was measured, and the rates follow the order A2780cisR > A2780 > HT-29. The reduction is not carried out by the low molecular weight (MW) antioxidants but primarily by cellular components with MW > 3000.
