Design, synthesis, and evaluation of a new class of exceptionally potent HIV-1 protease inhibitors are reported. Inhibitor 5 displayed superior antiviral activity and drug-resistance profiles. In fact, this inhibitor showed several orders of magnitude improved antiviral activity over the FDA approved drug darunavir. This inhibitor incorporates an unprecedented 6–5–5 ring-fused crown-like tetrahydropyranofuran
据报道,设计,合成和评估了一类新型的特别有效的HIV-1蛋白酶抑制剂。抑制剂5显示出优异的抗病毒活性和耐药性。实际上,与FDA批准的药物darunavir相比,该抑制剂的抗病毒活性提高了几个数量级。这种抑制剂结合了前所未有6-5-5的稠环冠状tetrahydropyranofuran作为P2配体和氨基苯并噻唑作为P2'配体与(- [R)-羟乙基磺酰胺等排物。该手性抑制剂的冠状P2配体已使用手性Diels-Alder催化剂以光学活性形式高效合成,提供了高对映体纯度的关键中间体。抑制剂结合的HIV-1蛋白酶的两个高分辨率X射线结构揭示了与HIV-1蛋白酶的骨架原子的广泛相互作用,并提供了对这些新抑制剂结合特性的分子洞察力。
