Kinetic analyses and fluorescent probe binding studies showed that several molecular tongs can inhibit PR dimerization. The best nonpeptidic molecular tongs to date were obtained with an inhibition constant Kid of 50 nM for PR and 80 nM for the multimutated protease ANAM-11. The PR inhibition was selective, the aspartic proteases renin and pepsin were not inhibited.
我们设计和合成了一种基于刚性萘基支架的新型分子钳,并评估了它们对HIV-1蛋白酶(PR)的抗二聚体活性。我们将羰基酰肼和寡酰肼(叠氮化物)片段插入它们的拟肽臂中,以减少疏水性并增加代谢稳定性。这些片段旨在通过复制天然PR中两个单体的N和C端之间形成的反平行β折叠中的氢键模式来破坏蛋白质之间的相互作用。动力学分析和荧光探针结合研究表明,几种分子钳可以抑制PR二聚化。迄今为止,最佳非肽类分子钳具有抑制常数K id对于PR为50nM,对于多突变蛋白酶ANAM-11为80nM。PR抑制是选择性的,天冬氨酸蛋白酶肾素和胃蛋白酶不被抑制。
