A series of novel oxyindole-derived HIV-1proteaseinhibitors were designed and synthesized based upon our X-ray crystal structure of inhibitor 2 (TMC-114) bound to HIV-1protease. The effects of substituents, spirocyclic rings, and ring sizes have been investigated. A number of inhibitors exhibited low nanomolar inhibitory potencies against HIV protease.

The structure-based design, synthesis, and biological evaluation of a series of nonpeptidic macrocyclic HIV proteaseinhibitors are described. The inhibitors are designed to effectively fill in the hydrophobic pocket in the S1′−S2′ subsites and retain all major hydrogen bonding interactions with the protein backbone similar to darunavir (1) or inhibitor 2. The ring size, the effect of methyl substitution
描述了一系列非肽大环 HIV 蛋白酶抑制剂的基于结构的设计、合成和生物学评价。抑制剂旨在有效填充 S1'-S2' 亚位点中的疏水口袋,并保留与蛋白质骨架的所有主要氢键相互作用,类似于地瑞那韦(1)或抑制剂2. 评估了大环结构内的环大小、甲基取代的影响和不饱和度。一般来说,环状抑制剂比它们的非环状同系物更有效,饱和环的活性低于它们的不饱和类似物,并且揭示了对 10 元和 13 元大环的偏好。添加甲基取代基导致效力降低。抑制剂14b和14c均表现出显着的酶抑制和抗病毒活性,并且它们对多重耐药的 HIV-1 变体具有强大的活性。抑制剂2和14c的蛋白质-配体 X 射线结构提供了对配体结合位点相互作用的重要分子洞察。
