protease, are believed to be highly effective in suppressing the viral replication. Among the HIV-1 integrase inhibitors, the beta-diketo acids (DKAs) represent a major lead for anti-HIV-1 drug development. In this study, novel bifunctional quinolonyl diketo acid derivatives were designed, synthesized, and tested for their inhibitory ability against HIV-1 integrase. The compounds are potent inhibitors
病毒编码的整合酶蛋白是HIV-1病毒生命周期中必不可少的酶,并且在开发抗HIV感染的疗法中代表了有吸引力且经过验证的目标。当与逆转录酶和蛋白酶的抑制剂联合使用时,选择性抑制该酶的药物被认为在抑制病毒复制方面非常有效。在HIV-1整合酶抑制剂中,β-二酮酸(DKA)代表了抗HIV-1药物开发的主要线索。在这项研究中,新型双功能喹啉基二酮酸衍生物被设计,合成并测试了其对HIV-1整合酶的抑制能力。该化合物是整合酶活性的有效抑制剂。尤其是,衍生物8对反应的两个步骤都是有效的IN抑制剂(3' -加工和链转移),并且对HIV-1感染的细胞显示出高抗病毒活性,并且细胞毒性也低。分子建模研究提供了一种可行的作用机理,这与配体SAR和酶光交联实验相符。
