B 85-0040 is a new cisplatin analog with dose-limiting myelosuppression.The maximum tolerated dose ranges between 300 and 525 mg/kg for single i.p. bolus injection in mice.Its toxicity is circadian-stage dependent with optimal tolerance between 16 and 17 h after lights on.B 85-0040 is active in L1210 leukemia.Antitumor activity seems to be unrelated to the circadian stage of treatment.Optimal drug timing can therefore increase its therapeutic index.
