  Peptidyl human heart chymase inhibitors. 1. Synthesis and inhibitory activity of difluoromethylene ketone derivatives bearing P′ binding subsites

  摘要：

  Peptidyl difluoromethylene ketone derivatives were designed to take advantage of probable additional interactions with the S' subsite of human heart chymase. They showed potent inhibitory activities against human heart chymase and were more efficient than bovine chymotrypsin. (C) 1998 Elsevier Science Ltd. All rights reserved.

  二氟酮类肽模拟物提示阿尔茨海默氏病的γ-分泌酶有较大的S1口袋：这对抑制剂设计具有重要意义。

  摘要：

  与阿尔茨海默氏病的病因有关的淀粉样β蛋白（Abeta）的生成的最后一步是通过γ-分泌酶在淀粉样前体蛋白（APP）的跨膜区域内进行蛋白水解。尽管γ-分泌酶被认为是治疗设计的重要目标，但尚未被充分表征或确定。我们实验室中先前使用基于底物的二氟酮和二氟醇过渡态类似物抑制剂的研究表明，γ-分泌酶是天冬氨酰蛋白酶，具有宽松的序列特异性。为了进一步表征γ-分泌酶的活性位点，我们制备了一系列在P1位置具有不同空间体积的二氟酮肽类似物，并测试了这些化合物抑制APP转染细胞中Abeta产生的能力。庞大的脂肪族P1侧链（如仲丁基或环己基甲基）的引入导致增加的γ-分泌酶抑制能力，这表明一个大的S1口袋可容纳这些取代基，并为松散的序列特异性提供了进一步的证据。环己基甲基P1取代基可将N端截短为低分子量化合物（<600 Da），该化合物有效地阻断了Abeta的产生（IC（50）约为5 microM）。该发现表明，最

  Peptides that contain difluorostatine and difluorostatone residues have been shown to be potent inhibitors of the aspartyl protease renin. The readily hydrated fluoro ketone is proposed to mimic the tetrahedral intermediate that forms during the enzyme-catalyzed hydrolysis of a peptidic bond. It is suggested that the sp3-hybridized ketal acts as a transition-state analogue renin inhibitor. The fluoro

  A series of primate renin inhibitors containing difluorocarbinol and difluoroketone groups at the P1-P1' position have been synthesized and studied both in vitro and in vivo. In vitro, the compounds were evaluated as inhibitors of monkey renin and the closely related aspartic proteinase, cathepsin D (bovine), as a measure of enzyme selectivity. Interestingly, the difluoroketone derivatives showed greatly reduced selectivity compared with the corresponding alcohols. However, selectivity could be enhanced by judicious choice of other substituents. Sites influencing selectivity, included not only P2, Which is well-known to strongly affect selectivity, but also the P4, P1-P1', and P2' sites. These results make possible the design of inhibitors with a greater selectivity for either renin versus cathepsin D. In vivo several of the compounds in the difluoroketone series have shown good oral activity in the salt depleted normotensive cynomolgus monkey model.

  Appropriate structural modification of the difluoromethylene ketone derivatives at both P3 and P' positions led us to the discovery of peptidyl human heart chymase inhibitor 12h which shows potent activity with Ki = 6 nM and high selectivity against closely related serine protease bovine alpha-chymotrypsin (chymotrypsin Ki = >100 mu M). Using the compound 12b, a docking study with human heart chymase was carried out to presume probable interactions, (C) 1998 Elsevier Science Ltd. All rights reserved.
