Effects of certain antitumor platinum compounds on kidney esterases

Abstract

In a study of the biochemical mechanism of renal toxicity of certain antitumor platinum compounds, particularly cis-dichlorodiammineplatinum(II) (NSC-119875), qualitative and quantitative studies of the soluble nonspecific kidney esterases were carried out using (C57BL/6 x DBA/2) mice. There was a major suppression of the testosterone-dependent esterases of treated male mice; these levels dropped to levels below those found in untreated females within 72 h after certain of the drugs were administered. This effect appeared to be in inverse relationship to the numerical value of the LD₅₀ values of the compounds investigated.
