3â²-β-Carbamoylmethylcytidine (CAMC) and its derivatives were synthesized using an intramolecular Reformatsky-type reaction promoted by SmI2 as the key step. In vitro tumor cell growth inhibitory activity was evaluated and CAMC was found to exhibit potent cytotoxicity against various human tumor cell lines. From a structureâactivity relationship study it was postulated that the cytotoxic mechanism of action of CAMC did not require phosphorylation at the 5â²-hydroxyl group. This study provides a novel strategy for the development of a new type of antitumor nucleoside.
以 SmI2 促进的分子内 Reformatsky 型反应为关键步骤,合成了 3â²-β-Carbamoylmethylcytidine (CAMC) 及其衍生物。对体外肿瘤细胞生长抑制活性进行了评估,发现 CAMC 对多种人类肿瘤细胞株具有很强的细胞毒性。根据结构与活性关系研究推测,CAMC 的细胞毒性作用机制不需要 5²-羟基上的磷酸化。这项研究为开发新型抗肿瘤核苷提供了一种新策略。
