title: Lack of cross-resistance between certain platinum coordination compounds in mouse leukemia.
abstract: Two congeners of cis-platinum diamminodichloride, 1,2-diamminocyclohexylplatinum malonate (NSC 224964) and 1,2-cyclohexyldiamminoplatinum sulfate (NSC 250427), show approximately equal inhibitory activity in vitro against leukemia L1210 and a line of L1210 (L1210/PDD) that has developed resistance to cis-platinum diamminodichloride. These compounds are also active against L1210/PDD in vivo. These observations suggest that they be tried clinically in patients whose disease has become resistant to cis-platinum diamminodichloride.
