chemically more stable than the furano lead, but it was shown to be significantly less antivirally active than its parent nucleoside analogue. It was noted to have a 10-fold lower inhibitory activity against the VZV-encoded thymidine kinase. This reduction of activity may be attributed to the different conformation of the sugar and base, as predicted by computational studies and supported by NMR studies
碳环核苷类似物是分解代谢稳定的,因为它们对嘧啶核苷磷酸化酶的磷酸裂解具有抗性。以碳环2'-脱氧尿苷为起始原料,合成了高效,高选择性的VZV双环核苷类似物(BCNA)6-戊基苯基呋喃[2,3-d]嘧啶-2'-脱氧核糖的碳环类似物(C-BCNA)。 。发现C-BCNA在化学上比呋喃诺铅更稳定,但已证明其抗病毒活性远低于其母体核苷类似物。注意到对VZV编码的胸苷激酶的抑制活性降低了10倍。活性的这种降低可以归因于糖和碱的不同构象,如通过计算研究预测并得到NMR研究支持。然而,
