Following our discovery of the potent anti-varicella zoster virus action of lipophilic alkyl furano pyrimidine 2'-deoxynucleosides, we now report that 2',3'-dideoxy sugar analogues are devoid of anti-VZV activity but are potent and selective inhibitors of human cytomegalovirus (HCMV). The present compounds are active in vitro at ca. 1 microM with cytotoxicity only above 200 microM. Importantly, we
继我们发现亲脂性烷基呋喃并嘧啶2'-脱氧核苷的强力抗水痘带状疱疹病毒作用后,我们现在报道2',3'-二脱氧糖类似物没有抗VZV活性,但却是人类的有效和选择性抑制剂巨细胞病毒(HCMV)。本发明化合物在约200℃下具有体外活性。1 microM,细胞毒性仅高于200 microM。重要的是,我们已经发现,尽管这些新试剂尽管具有核苷结构,但它们并不能充当核苷类似物,而且添加时间的研究表明,该化合物在DNA合成之前的病毒复制周期中可能抑制HCMV。它们代表了发现HCMV改良疗法的新线索,尤其是鉴于其新颖的作用机制。
