The design and synthesis of novel HIV-1 protease inhibitors (PIs) (1–22), which display high potency against HIV-1 wild-type and multi-PI-resistant HIV-mutant clinical isolates, is described. Lead optimization was initiated from compound 1, a Phe–Phe hydroxyethylene peptidomimetic PI, and was directed towards the discovery of new PIs suitable for a long-acting (LA) injectable drug application.

描述了新型HIV-1蛋白酶抑制剂(PIs)(1-22)的设计和合成,这些抑制剂对HIV-1野生型和耐多种PI的HIV突变体临床分离株显示出高效力。铅优化从化合物1(一种Phe-Phe羟乙烯拟肽PI)开始,并旨在发现适用于长效(LA)注射药物应用的新PI。引入杂环6-甲氧基-3-吡啶基或6-(二甲基氨基)-3-吡啶基部分(R 3在)对位P1'苄基片段的位置在低个位数纳摩尔范围内具有抗病毒效力的化合物。各种芳香环上新陈代谢热点的卤化或烷基化导致PI对人肝微粒体的降解具有很高的稳定性,并且在大鼠中的血浆清除率较低。更换chromanolamine部分(R 1在P2)蛋白酶由cyclopentanolamine或cyclohexanolamine衍生物的结合位点提供了一系列的高清除率的PI(16 - 22与EC)50的HIV-1中的0.8-范围上野生型S 1.8 nM。效绩指标18和22制成纳米混
