structure-based design and synthesis of a series of novel nonpeptide HIV protease inhibitors are described. The inhibitors were designed based upon the X-ray crystal structure of inhibitor 1 (UIC-94017)-bound HIV-1 protease. The inhibitors incorporated 3-hydroxysalicyclic acid-derived acyclic and cyclic P2 ligand into the (R)-(hydroxyethylamino)sulfonamide isostere. The inhibitors contain only two
描述了一系列新型非肽HIV蛋白酶抑制剂的基于结构的设计和合成。根据抑制剂1(UIC-94017)结合的HIV-1蛋白酶的X射线晶体结构设计抑制剂。抑制剂将3-羟基水杨酸衍生的无环和环状P2配体掺入(R)-(羟乙基氨基)磺酰胺等排物中。抑制剂仅包含两个手性中心,并利用Grubbs催化剂作为关键步骤,利用Sharpless不对称环氧化,区域选择性环氧化物开环和闭环烯烃复分解以旋光形式轻松合成。我们已经合成了13-15元环酰胺,并评估了它们在MT-2细胞中对HIV-1蛋白酶的抑制和抗病毒活性。有趣的是,所有衍生自环酰胺的抑制剂都比相应的无环化合物更有效。研究了环的大小和取代基的影响。事实证明,HIV-1蛋白酶的S(1)-S(2)活性位点优选14元饱和环。Macrocycle 26表现出出色的酶抑制效能,K(i)值为0.7 nM,抗病毒IC(50)值为0.3 microM。考虑到它们的结构简单性和
