series of potent HIV-1 protease inhibitors are described. Various polar functionalities have been incorporated on the tetrahydropyranyl-tetrahydrofuran-derived P2 ligand to interact with the backbone atoms in the S2-subsite. The majority of the inhibitors showed very potent enzyme inhibitory and antiviral activity. Two high-resolution X-ray structures of 30b- and 30j-bound HIV-1 protease provide insight
描述了一系列有效的 HIV-1 蛋白酶抑制剂的设计、合成、生物学和 X 射线晶体学研究。四氢吡喃基-四氢呋喃衍生的 P2 配体上已引入各种极性官能团,以与 S2 子位点中的主链原子相互作用。大多数抑制剂表现出非常有效的酶抑制和抗病毒活性。30b和30j结合的 HIV-1 蛋白酶的两个高分辨率 X 射线结构提供了对配体结合位点相互作用的深入了解。特别是,P2-配体上的极性官能团似乎与瓣区中的 Gly48 酰胺 NH 和酰胺羰基形成独特的氢键。
