title: Thiol and thioether suppression of cis-platinum-induced nephrotoxicity in rats bearing the Walker 256 carcinosarcoma.
abstract: An examination of eighteen thiols and thio ethers revealed that the simultaneous administration of several of these with cis-platinum (CDDP) at 7.5 mg/kg (25 mumols/kg) iv, as a single injection to rats bearing the Walker 256 carcinosarcoma led to significant reduction in the nephrotoxicity typically found with cis-platinum, and no apparent interference in its anti-neoplastic action towards this tumor. The thiols and thiol ethers were administered at a twenty-fold molar excess to the CDDP and were combined with the CDDP immediately prior to administration. The most effective compounds in suppression nephrotoxicity were D-, and L-methionine, methyl and ethyl L-methioninate, and N-acetyl-D, L-methionine.
