5‐b]pyridin‐2‐ylthioacetanilides were designed, synthesized, and evaluated for their antiviral activities through combining bioisosteric replacement and structure‐based drug design. Almost all of the title compounds displayed moderate to good activities against wild‐type (wt) HIV‐1 strain with EC50 values ranging from 0.059 to 1.41 μm in a cell‐based antiviral assay. Thereinto, compounds 12 and 13 were the most
随着我们为发现有效的HIV-1 NNRTIs的不懈努力,我们设计了一系列新型咪唑并[4,5-b]吡啶-2--2-基硫代乙酰胺,并通过生物等排代用品和生物等效性评估了它们的抗病毒活性。基于结构的药物设计。几乎所有的标题化合物显示中等至对野生型(wt)HIV-1毒株具有EC良好活动50个值范围从0.059到1.41μ米在基于细胞的抗病毒测定。到其中,化合物12和13是最活跃2代的类似物具有的EC 50 0.059 0.073μ值米对抗WT HIV-1,分别,这比对照药物奈韦拉平更有效(EC 50 = 0.26μ米)并且与地拉呋啶(EC 50 = 0.038μ米)。另外,与奈韦拉平和依曲韦林相比,一种选择的化合物显示出显着的逆转录酶抑制活性。在本文的最后,详细讨论了初步的结构-活性关系(SAR)和分子建模研究,这可能为进一步优化提供有价值的见解。
