ofuranosylcytosines (9–17) were prepared by Cu(I)-mediated [3 + 2] cycloaddition reactions (CuAAC) of 1-(4′-azido-2′-deoxy-2′-fluoro-β-d-arabinofuranosyl)cytosine (1) with appropriate alkynes in good yields. Their structures were fully established by 1H NMR, 13C NMR, HRMS, and elemental analysis. Most of these nucleoside analogs exhibited potent anti-HIV-1 activity with no cytotoxicity observed at
一系列的4' - [1,2,3]三唑基-2'-脱氧-2'-氟-β- d -arabinofuranosylcytosines(9 - 17)由铜制备(I)介导的[3 + 2]环加成1-(4'-叠氮基-2'-脱氧-2'-氟-β - d-阿拉伯呋喃糖基)胞嘧啶(1)与合适的炔烃的反应(CuAAC)具有良好的收率。它们的结构通过1 H NMR,13 C NMR,HRMS和元素分析完全确定。这些核苷类似物中的大多数都显示出有效的抗HIV-1活性,在最高25μM的最高测试浓度下未观察到细胞毒性。其中,化合物9,10和13由于其具有极强的抗病毒活性,因此作为治疗HIV-1感染的新型核苷逆转录酶抑制剂(NRTIs)具有巨大的发展潜力。此外,化合物的抗HBV活性10,11和17进行了调查。
