excretion of peptide-derived HIV protease inhibitors have limited their utility as potential therapeutic agents. Our broad screening program to discover non-peptidic HIV protease inhibitors previously identified compound I (phenprocoumon, Ki = 1 microM) as a lead template. Structure-based design of potent non-peptidic inhibitors, utilizing crystal structures of HIV protease/inhibitor complexes, provided
肽衍生的HIV蛋白酶抑制剂的低口服生物利用度和快速胆汁排泄限制了它们作为潜在治疗剂的用途。我们广泛的筛选程序旨在发现非肽类HIV蛋白酶抑制剂,先前已将化合物I(苯普鲁蒙,Ki = 1 microM)鉴定为先导模板。利用HIV蛋白酶/抑制剂复合物的晶体结构,有效的非肽类抑制剂的基于结构的设计为先前报道的含羧酰胺的4-羟基香豆素和4-羟基-2-吡喃酮提供了合理的基础。含氨基酸的化合物V(Ki = 4 nM)提供了一个有前途的新系列HIV蛋白酶抑制剂的实例,该酶具有显着改善的酶结合亲和力。在这份报告中,进一步的构效关系研究,其中的羧酰胺被磺酰胺官能团取代,导致鉴定出另一系列的非氨基酸类含有前途的抑制剂,这些抑制剂具有显着增强的酶结合亲和力和体外抗病毒活性。含磺酰胺的吡喃酮XVIII(Ki = 0.5 nM)中活性最高的非对映异构体显示出更高的抗病毒活性(IC50 = 0.6 nM),并且是发现更
