The design, synthesis, and crystallographic analysis of protein-inhibitor complexes is described for a novel series of nonpeptidic HIV protease (HIV Pr)inhibitors. Beginning with a cocrystal structure of a Phe-Pro peptidomimetic bound to the HIV Pr, design was initiated that resulted in the substituted 2-butanol compound 8 as the lead compound (Ki = 24.5 microM, racemic mixture). Modifications on the
蛋白质抑制剂复合物的设计,合成和晶体学分析描述了一系列新型非肽类HIV蛋白酶(HIV Pr)抑制剂。从与HIV Pr结合的Phe-Pro拟肽的共晶体结构开始,开始设计,最终得到取代的2-丁醇化合物8作为前导化合物(Ki = 24.5 microM,外消旋混合物)。然后根据其与HIV Pr的共晶结构和抑制数据对初始化合物进行修饰,从而产生具有增强的针对该酶的效力的化合物(化合物18,Ki = 0.48 microM)。发现这些抑制剂基本上根据原始设计假设所预测的与酶结合。单个对映异构体的立体特异性合成证实了对S醇立体化学的结合偏好的预测。在感染了HIV-1的CEM-SS细胞系中,对几种更有效的HIV Pr抑制剂表现出了适度的抗病毒活性。
