Mono(trifluoroacetato)platinum(IV) complexes of the formula [Pt-IV(dach)L-3(TFAc)] (dach = trans-(+/-)-1,2-diaminocyclohexane, TFAc = trifluoroacetate, L = acetate or propionate) could be prepared from the reaction of [Pt-IV(dach)L-3(OH)] with trifluoroacetic anhydride in the presence of a base and the crystal structure of compound 4 was determined by X-ray crystallography. In vitro antitumor activity of complex 4 (ED50 = 3.1 muM) was found to be much higher than carboplatin (ED50 = 10.2 muM). (C) 2004 Elsevier B.V. All rights reserved.
