Compounds 10 and 11 exhibited potent anti-HIV-1 activity (EC50: 0.3 and 0.13 nM, respectively) without significant cytotoxicity in concentrations up to 100 μM. Compound 11 exhibited extremely potent anti-HIV activity against NL4-3 (wild-type), NL4-3 (K101E), and RTMDR viral strains, with EC50 values of 0.086, 0.15, and 0.11 nM, respectively. Due to the high potency of 11, it was also screened against
我们制备了 1-(4'-azido-2'-deoxy-2'-fluoro- β - d - arabinofuranosyl)cytosine ( 10 ) 及其盐酸盐 ( 11 ) 作为潜在的抗病毒剂,基于 4' 的良好抗病毒特性。 -取代的核苷。化合物10和11从1,3,5-合成ö -tribenzoyl -2-脱氧-2-氟- d在多个步骤-arabinofuranoside,并明确地通过IR,建立了结构1 H NMR,13 C NMR,和19 F NMR 光谱、HRMS 和 X 射线晶体学。化合物10和11表现出有效的抗 HIV-1 活性(EC 50分别为 0.3 和 0.13 nM),在高达 100 μM 的浓度下没有显着的细胞毒性。化合物11对 NL4-3(野生型)、NL4-3(K101E)和 RTMDR 病毒株表现出极强的抗 HIV 活性,EC 50值分别为0.086、0.15和
