designed accordingly to yield new sulphonamides derivatives. A water based green synthetic approach was adopted to obtain these compounds which were evaluated for their HIV-1 gp120 CD4 binding inhibition. The newly synthesized compounds exhibited remarkable activity (10-fold increase) when compared with the standard BMS 806. Further the stability of newly synthesized derivatives with HIV-1 gp120 was also investigated
包膜糖蛋白gp120与宿主细胞受体CD4的连接是人类免疫缺陷病毒1(HIV-1)进入宿主细胞的第一步,这使其成为有希望的药物设计靶标。为了阐明已报道的HIV-1 gp120 CD4结合抑制剂的关键三维(3D)结构特征,生成了3D药效团,并采用了基于受体的方法来量化这些结构特征。为100个分子的数据集生成了具有良好统计和预测能力的四部分最小平方因子模型。为了进一步确定gp120-CD4结合抑制的结构要求,通过使用Glide 5.6进行分子对接来进行抑制剂与gp120的分子相互作用研究。根据这些研究,提出了结构要求,并相应地设计了新的分子以产生新的磺酰胺衍生物。采用水基绿色合成方法来获得这些化合物,并对其HIV-1 gp120 CD4结合抑制作用进行了评估。与标准BMS 806相比,新合成的化合物显示出显着的活性(增加了10倍)。此外,还通过分子动力学模拟研究了HIV-1 gp120的新合成衍
