Several CD4 mimics have been reported as HIV-1 entry inhibitors that can intervene in the interaction between a viral envelope glycoprotein gp120 and a cell surface protein CD4. Our previous SAR studies led to a finding of a highly potent analogue 3 with bulky hydrophobic groups on a piperidine moiety. In the present study, the aromatic ring of 3 was modified systematically in an attempt to improve
据报道,有几种CD4模拟物是HIV-1进入抑制剂,它们可以干预病毒包膜糖蛋白gp120与细胞表面蛋白CD4之间的相互作用。我们以前的SAR研究导致发现了高效有效的类似物3,在哌啶部分带有大量疏水基团。在本研究中,系统地修饰了3的芳香环,以试图改善其抗病毒活性和CD4模仿性,从而诱导gp120的构象变化,从而使包膜对中和抗体更加敏感。合成化合物的生物学分析表明,氟基团作为间位基团的引入芳环的取代基引起抗HIV活性的增加和CD4拟态的增强,并导致新型化合物13a的抗HIV活性是3的两倍,甚至在CD4拟态上也有显着提高在较低的浓度。
