Nephrotoxic potential of cis-diamminedichloroplatinum and four analogs in male Fischer 344 rats.

Cis-diamminedichloroplatinum [cis-DDP; NSC-119875] and four analogs (NSC-241240, NSC-271674, NSC-263158, and NSC-268252) were evaluated for their acute nephrotoxic potential in male F344 rats following iv administration. Indices of nephrotoxicity included blood urea nitrogen, serum creatinine, kidney weights, and microscopic examination. Results indicated that renal function, organ weights, and histology are important criteria for assessing the nephrotoxic potential of cis-DDP analogs, although alterations in these parameters may have been influenced by severe body weight loss. cis-DDP appeared to be the most nephrotoxic compound studied, and NSC-241240 demonstrated minimal renal damage. Ranking of compounds in order of their nephrotoxic potential (most to least) was cis-DDP, NSC-263158, NSC-268252, NSC-271674, and NSC-241240.
