7-substituted 4-aminopyrrolo[2,3-d]pyrimidines related to the nucleosides toyocamycin and thiosangivamycin were prepared and tested for their activity against human cytomegalovirus (HCMV). The nucleosides 2'-deoxytoyocamycin (1), xylo-toyocamycin (2), 3'-deoxytoyocamycin (3), 2',3'-dideoxy-2',3'-didehydrotoyocamycin (4), 2',3'-dideoxytoyocamycin (5), ara-toyocamycin (6), 2'-deoxy-2'-amino-ara-toyocamycin
制备了一系列与核苷丰卡霉素和硫代桑奇霉素有关的7-取代的4-氨基吡咯并[2,3-d]嘧啶,并测试了它们对人巨细胞病毒(HCMV)的活性。核苷2'-脱氧代代霉素(1),木糖-代代霉素(2),3'-脱氧代代霉素(3),2',3'-脱氧代代-2',3'-脱氢代代代霉素(4),2',3'-用就地生成的硫化氢处理二脱氧代代霉素(5),阿拉伯代代霉素(6),2'-脱氧-2'-氨基-代代代霉素(7)和5'-脱氧代代霉素(8)。 thiosangivamycin类似物(9-16)。通过修改文献方法合成氰基衍生物1-8。所有的硫代酰胺衍生物(9-16)均具有抗HCMV的活性,IC50为0.5至6 microM。大多数还对1型单纯疱疹病毒(HSV-1)具有活性,但浓度较高。在两种人类细胞系中,抗病毒活性并未与细胞毒性完全分开。糖基上修饰的位置强烈影响抗增殖活性。与在2',5'或2',3'位置进行修饰的木糖基和
