the favorable antiviral profiles of 4′-substituted nucleosides, novel 1-(2′-deoxy-2′-fluoro-4′-C-ethynyl-β-d-arabinofuranosyl)-uracil (1a), -thymine (1b), and -cytosine (2) analogs were synthesized. Compounds 1b and 2 exhibited potent anti-HIV-1 activity with IC50 values of 86 and 1.34 nM, respectively, without significant cytotoxicity. Compound 2 was 35-fold more potent than AZT against wild-type
基于 4'-取代核苷的良好抗病毒特性,新型 1-(2'-deoxy-2'-fluoro-4'- C - ethynyl -β- d - arabinofuranosyl)-uracil ( 1a ), -thymine ( 1b) ) 和 -胞嘧啶 ( 2 ) 类似物被合成。化合物1b和2表现出有效的抗 HIV-1 活性,IC 50值分别为 86 和 1.34 nM,没有显着的细胞毒性。化合物2对野生型病毒的效力是 AZT 的 35 倍,并且还保留了对耐药株、NL4-3 (K101E) 和 RTMDR 的纳摩尔级抗病毒活性。因此,2作为一种新型 NRTI 药物值得进一步开发。
