the well-studied halogen-substituted benzyl fragment. With the focus on the mentioned diversity point, a medium-sized library of compounds was selected for synthesis. A biological study revealed that many molecules were highly active INSTIs (EC50 < 10 nM). Two compounds 14} and 126} demonstrated picomolar antiviral activity that was comparable with CAB and were more active than DTG and BIC. Molecular
尽管目前有相对广泛的治疗选择可用于治疗HIV / AIDS,但它仍然是最严重和最致命的疾病之一,并且死亡率很高。整合酶链转移抑制剂(INSTI),例如FDA批准的dolutegravir(DTG),bictegravir(BIC)和cabotegravir(CAB),最近已作为标准的高效抗逆转录病毒疗法(HAART)方案中的五种主要成分之一获得最有益的临床结果。在本文中,我们描述了包含杂芳族生物等位取代而不是经过充分研究的卤素取代的苄基片段的新型INSTI的组合酰胺合成,生物学评估和计算机模拟。着眼于上述多样性点,选择了中等大小的化合物文库进行合成。一项生物学研究表明,许多分子是高活性的INSTI(EC50 <10 nM)。两种化合物1 4}和1 26}表现出与CAB相当的皮摩尔抗病毒活性,并且比DTG和BIC更具活性。进行了分子对接研究以评估化合物在HIV-1 IN活性位点的结合模式。在大鼠中,铅化合物1
