As part of our anti-hepatitis C program, we recently discovered 2'-C-methylcytidine (1) and 2'-C-methyluridine (2), which are potent inhibitors in cell culture of several viruses (bovine viral diarrhea virus (BVDV), yellow fever virus (YFV)) closely related to HCV. In order to characterize structure-activity relationships, we introduced some structural and functional modifications into the 3'-position of 2'-C-methylcytidine and 2'-C-methyluridine. All these hitherto unknown compounds thus synthesized were tested for the activity against a wide range of viruses and found to be inactive.
作为我们的抗丙型肝炎计划的一部分,我们最近发现了2'-C-甲基胞苷(1)和2'-C-甲基尿苷(2),它们在细胞培养中是几种与HCV密切相关的病毒(牛病毒性腹泻病毒(BVDV)、黄热病病毒(YFV))的有效抑制剂。为了表征结构活性关系,我们对2'-C-甲基胞苷和2'-C-甲基尿苷的3'-位置进行了一些结构和功能修饰。这些迄今为止未知的合成化合物被测试其对广泛病毒的活性,结果发现它们均无效。
