Synthetic Studies on 2′-Substituted-4′-thiocytidine Derivatives as Antineoplastic Agents
摘要:
As potential antineoplastic agents, we have synthesized 4'-thioFAC and 4'-thiocytarazid by developing an alternative synthetic method. 4'-ThioFAC showed potent antineoplastic activities in vivo as well as in vitro.
