biliary excretion of peptide-derived HIV protease inhibitors have limited their utility as potential therapeutic agents. Our broad screening program to discover nonpeptidic HIV protease inhibitors had previously identified compound II (phenprocoumon, K(i) = 1 muM) as a lead template. Crystal structures of HIV protease complexes containing the peptide-derived inhibitor I (1-(naphthoxyacetyl)-L-histidyl
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。我们广泛的发现非肽类HIV蛋白酶抑制剂的筛选程序先前已将化合物II(苯普鲁蒙,K(i)= 1μM)鉴定为先导模板。包含肽衍生抑制剂I(1-(萘氧基乙酰基)-L-组氨酸5(S)-氨基-6-环己基-3(R),4(R)-二羟基-2(R)的HIV蛋白酶复合物的晶体结构)-异丙基己酰基-L-异亮氨酸N-(2-吡啶基甲基)酰胺)和非肽类抑制剂(如苯丙香酚(化合物II))为更多活性类似物的基于结构的设计提供了合理的基础。这项研究报告了重要的发现,即在功能上适当地添加到4-羟基香豆素和4-羟基-2-吡喃酮模板中的羧酰胺可产生一系列新的有希望的具有改善的酶结合亲和力的非肽类HIV蛋白酶抑制剂。含羧酰胺的化合物XXIV中活性最高的非对映异构体抑制HIV-1蛋白酶,其K(i)值为0.0014μM。这项研究为发现更有效的HI
