polyprotein to form functional and structural proteins of HCV. The enzyme has a shallow binding pocket at the catalytic site, making development of inhibitors difficult. We have designed, preorganized, and depeptidized macrocyclic inhibitors from P(4) to P(2)' and optimized binding to 0.1 microM. The structure of an inhibitor bound to the enzyme was also solved.
丙型肝炎病毒(HCV)NS3与NS-4A辅因子结合后,可通过催化多蛋白的裂解形成HCV的功能性和结构性蛋白来促进成熟的病毒体的发育。该酶在催化位点处有一个浅的结合袋,使抑制剂的开发变得困难。我们已经设计,预组织和去肽大环抑制剂从P(4)到P(2)',并优化了与0.1 microM的结合。还解决了与酶结合的抑制剂的结构。
