(9) precursors. The oxiranyl nucleoside analogues (8 and 20) were obtained by epoxidation of 1 and 9 with m-chloroperoxybenzoic acid and subsequent coupling with adenine. The new compounds were evaluated for their antiviral and antitumor cell activities. Among the olefinic nucleoside analogues, Z-isomer of adenine containing 4-amino-2-butenyl side chain (6) exhibited the best cytostatic activities, particularly
合成了一系列新颖的嘌呤和嘧啶核苷类似物,其中糖部分被4-氨基-2-丁烯基(2-6和10-18)和环氧乙烷基(8和20)间隔基取代。不饱和无环核苷类似物的Z-(2-6)和E-异构体(10-18)是通过将2和6个取代的嘌呤和5个取代的尿嘧啶碱基与Z-(1)或E-邻苯二甲酰亚胺缩合而合成的(9)前体。环氧乙烷基核苷类似物(8和20)是通过1和9与间氯过氧苯甲酸环氧化并随后与腺嘌呤偶联而获得的。对新化合物的抗病毒和抗肿瘤细胞活性进行了评估。在烯属核苷类似物中,含有4-氨基-2-丁烯基侧链的腺嘌呤的Z-异构体(6)表现出最佳的细胞抑制活性,尤其是对结肠癌的抑制作用(SW 620,IC50 = 26 microM)。它的E-异构体15除了对结肠癌(SW 620,IC50 = 56.5 microM)细胞有轻微抑制作用外,对恶性肿瘤细胞系没有任何抗增殖活性。通常,Z-异构体显示出比相应的E-异构体更好的
