HIV integrase is one of the three enzymes encoded by HIV genome and is essential for viral replication, but integrase inhibitors as marketed drugs have just very recently started to emerge. In this study, we show the evolution from the N-methylpyrimidinone structure to bicyclic pyrimidinones. Introduction of a suitably substituted amino moiety modulated the physical-chemical properties of the molecules
HIV整合酶是HIV基因组编码的三种酶之一,对于病毒复制至关重要,但是作为上市药物的整合酶抑制剂是最近才开始出现的。在这项研究中,我们显示了从N-甲基嘧啶酮结构向双环嘧啶酮的演变。引入适当取代的氨基部分可调节分子的物理化学性质,并在抑制HIV-1感染在细胞培养中扩散方面赋予纳米摩尔活性。广泛的SAR研究导致了磺酰胺(R)-22b,它以7 nM的IC50抑制了链转移,并以44 nM的CIC95抑制了MT4细胞中的HIV感染,
