Protection against cis-diamminedichloroplatinum-induced nephrotoxicity in rats by N-benzyl-D-glucamine dithiocarbamate.

Sodium N-benzyl-D-glucamine dithiocarbamate (BGD) was evaluated for its efficacy as an inhibitor of cis-diamminedichloroplatinum (DDP)-induced nephrotoxicity in a rat model. Treatment with 2.0 mmol/kg of BGD immediately after DDP injection effectively prevented nephrotoxic effects of DDP, but administration of BGD -1 or 1 h after DDP afforded a small protection. Concurrent treatment with 0.5 mmol/kg of BGD could not prevent renal damage. The platinum concentrations in liver and kidney were significantly decreased by BGD treatment. The antitumor efficacy of DDP in the Walker 256 carcinoma-bearing rats was not affected by administration of BGD (2.0 mmol/kg).
