A series of 2′-C-methyl branched purine and pyrimidine C-nucleosides were prepared. Their anti-HCV activity and pharmacological properties were profiled, and compared with known 2′-C-Me N-nucleoside counterparts. In particular, 2′-C-Me 4-aza-7,9-dideazaadenosine C-nucleoside (2) was found to have potent and selective anti-HCV activity in vitro as well as a favorable pharmacokinetic profile and in vivo
制备了一系列2'- C-甲基支链嘌呤和嘧啶C-核苷。对它们的抗 HCV 活性和药理特性进行了分析,并与已知的 2'- C- Me N-核苷对应物进行了比较。特别是,发现 2' - C -Me 4-aza-7,9-dideazaadenosine C -nucleoside ( 2)在体外具有有效和选择性的抗 HCV 活性以及良好的药代动力学特征和体内潜力效力优于相应的N-核苷。
