Two series of P1'-extended HIV-1 protease inhibitors comprising a tertiary alcohol in the transition-state mimic exhibiting Ki values ranging from 2.1 to 93 nM have been synthesized. Microwave-accelerated palladium-catalyzed cross-couplings were utilized to rapidly optimize the P1' side chain. High cellular antiviral potencies were encountered when the P1' benzyl group was elongated with a 3- or 4-pyridyl
合成了两个系列的P1'延伸的HIV-1蛋白酶抑制剂,它们在过渡态模拟物中包含叔醇,其Ki值在2.1到93 nM之间。微波加速钯催化的交叉偶联用于快速优化P1'侧链。当P1'苄基被3-或4-吡啶基取代基延长时,会遇到高细胞抗病毒效力(EC50 = 0.18-0.22 microM)。获得了与该酶共结晶的三种抑制剂的X射线晶体学数据。
