their structures were verified by spectroscopic techniques. Nucleosides 8 and 9 had only borderline activity against leukemia L1210 cells grown in culture, whereas nucleoside 11 had activity equal to 1. However, nucleoside 10 proved to be twice as active as either 1 or 11. The antileukemic activity, which was due to the inhibition of cell division, was reversible by transfer of the arrested cells to
基于先前在细胞培养物中发现的9-β-D-岩藻糖基腺嘌呤(1)的抗白血病特性,已从D-岩藻糖中制备了四个含有天然碱基的新核苷。在乙腈或1,2-二氯乙烷中,以氯化锡(IV)为催化剂,将α-D-呋喃葡萄糖四乙酸酯与甲硅烷基化的碱缩合。以结晶形式获得中间体保护的核苷,并用甲醇甲醇钠脱乙酰。将1-β-D-呋喃核糖基尿嘧啶(8),1-β-D-呋喃核糖基胸腺嘧啶(9),作为盐酸盐的1-β-D-呋喃核糖基胞嘧啶(10)和7-β-D-呋喃核糖基鸟嘌呤(11)进行了结晶。 ,并通过光谱技术验证了其结构。核苷8和9仅对培养物中生长的白血病L1210细胞具有临界活性,
