an even more potent HIV-1proteaseinhibitor (Ki = 0.8 nM, EC50 = 0.04 μM). According to X-rayanalysis, the new class of inhibitors did not fully succeed in forming two symmetric hydrogen bonds to the catalytic aspartates. The crystal structures of the complexes further explain the difference in potency between the shorter inhibitors (two-carbon spacer) and the longer inhibitors (three-carbon spacer)
为了确定一类新的类药物 HIV-1 蛋白酶抑制剂,已合成、生物学评估和共结晶四种不同的立体纯 β-羟基 γ-内酰胺抑制剂。还研究了中央间隔物(两个或三个碳)的系绳长度的影响。具有较短系链和 (3 R ,4 S ) 绝对构型的化合物表现出高活性,K i为 2.1 nM,EC 50为 0.64 μM。通过修饰 P1' 侧链进一步优化提供了更有效的 HIV-1 蛋白酶抑制剂(K i = 0.8 nM,EC 50= 0.04 μM)。根据 X 射线分析,新型抑制剂并没有完全成功地与催化天冬氨酸盐形成两个对称的氢键。复合物的晶体结构进一步解释了较短抑制剂(双碳间隔基)和较长抑制剂(三碳间隔基)之间效力的差异。
