structure-based design led to the activity enhancements of pyrone and dihydropyrone ring systems (II and V) and amide-based substitution (III). Incorporation of sulfonamide substitution within the dihydropyrone template provided a series of highly potent HIV protease inhibitors, with structure-activity relationships described in this paper. Crystallographic studies provided further information on important
之前,一项广泛的筛查程序将苯丙香酚(1)作为抑制HIV蛋白酶的小分子模板。通过基于结构的设计的迭代循环对该引线的后续修改导致了吡喃酮和二氢吡喃环系统(II和V)以及酰胺基取代(III)的活性增强。在二氢吡喃酮模板中掺入磺酰胺取代基提供了一系列高效的HIV蛋白酶抑制剂,具有本文所述的结构活性关系。晶体学研究提供了有关负责高酶结合的重要结合相互作用的进一步信息。这些研究最终形成了化合物VI,该化合物抑制HIV蛋白酶,其Ki值为8 pM,在抗病毒细胞培养中的IC90值为100 nM。
