Various 3-substituted 3'-azido-3'-deoxythymidine analogs (2a-i) were prepared by the reaction of 3'-azido-3'-deoxythymidine (1), AZT with N, N-dimethylformamide dialkylacetal or alkyl bromide in the presence of base and their activities against human-immunodeficiency virus type-1 (HIV-1) were evaluated. The corresponding 5'-triphosphate analogs (9) were also synthesized in order to examine inhibition of HIV-1 reverse transcriptase activity. Beyond expectation, some N3-derivatives of AZT were found to reserve the anti-HIV-1 activity to some extent. Among the compounds (2a-i) obtained, 3-allyl-AZT (2e) was the most active against HIV-1 replication in MT-4 cells in vitro with an EC50 value of 0.9μM. 3-Allyl-AZT 5'-triphosphate (9e), however, exhibited no inhibition of HIV-1 reverse transcriptase activity.
通过 3'-azido-3'-deoxythymidine (1)、AZT 与 N, N-二甲基甲酰胺二烷基缩醛或烷基溴在碱存在下的反应,制备了各种 3 取代的 3'-azido-3'-deoxythymidine 类似物(2a-i),并评估了它们对人类免疫缺陷病毒 1 型(HIV-1)的活性。为了研究对 HIV-1 逆转录酶活性的抑制作用,还合成了相应的 5'-三磷酸类似物(9)。超出预期的是,一些 AZT 的 N3 衍生物在一定程度上保留了抗 HIV-1 的活性。在获得的化合物(2a-i)中,3-烯丙基-AZT(2e)对 MT-4 细胞中 HIV-1 的体外复制最有效,EC50 值为 0.9μM。然而,3-烯丙基-AZT 5'-三磷酸酯(9e)对 HIV-1 逆转录酶活性没有抑制作用。
