group on the biological activity of the target molecules. Compounds 7a, b, 8a, b, and 13a, b were evaluated for their antiviral and cytostatic activity using several virus strains and cell lines. Whereas no marked antiviral activity was noticed, 13a and 13b showed a cytostatic activity that ranged between 7 and 23 μM for 13a and 26 and 38 μM for 13b against murine leukemia L1210, human lymphocyte Molt4/C8
本报告描述了作为潜在生物活性剂的不饱和外亚甲基lyxopyranonucleoside 类似物的合成。市售的 1,2,3,4-四-O-乙酰-α-D-lyxopyranose 1 分别与甲硅烷基化胸腺嘧啶和尿嘧啶缩合,脱乙酰和缩醛得到 1-(2,3-O-异亚丙基-α- D-lyxopyranosyl)thymine 4a 和 1-(2,3-O-isopropylidene-α-D-lyxopyranosyl)uracil 4b。新的衍生物 1-(2,3,4-trideoxy-4-methylene-α-pent-2-enopyranosyl)thymine 8a 和 1-(2,3,4-trideoxy-4-methylene-α-pent-2-为了阐明2',3'-不饱和度的影响并阐明酮基和外亚甲基之间的差异,通过两种不同的关键中间体7a、b和13a、b制备了烯吡喃基)尿嘧啶8b。目标分子。化合物
