As part of an ongoing program to develop novel antitumor agents over the years, we have synthesized and evaluated a number of 4′-C-substituted nucleosides. A few years ago, we reported the first synthesis of 4′-C-hydroxymethyl-2′-fluoro arabino nucleosides, which did not exhibit any cytotoxicity. In our exploration of related compounds, we synthesized and evaluated the 4′-C-methyl-2′-fluoro arabino
作为多年来开发新型抗肿瘤剂的持续计划的一部分,我们合成并评估了许多 4'-C 取代的核苷。几年前,我们报道了 4'-C-羟甲基-2'-氟阿拉伯核苷的首次合成,该核苷没有表现出任何细胞毒性。在我们对相关化合物的探索中,我们合成并评估了嘌呤和嘧啶系列中的 4'-C-甲基-2'-氟阿拉伯核苷。在嘧啶系列中,发现 1-(4-C-methyl-2-fluoro-β-D-arabinofuranosyl) 胞嘧啶 (13) 具有高度细胞毒性,并且在植入人类肿瘤异种移植物的小鼠中具有显着的抗肿瘤活性。报道了该系列核苷的合成和抗癌活性。
