  Tri- and tetrapeptide analogs of kinins as potential renal vasodilators

  摘要：

  Tri- and tetrapeptide analogues were synthesized and evaluated as renal vasodilators. These peptides were prepared by standard coupling reactions, which also provided good yields with hindered alpha-methyl amino acid derivatives. Preliminary evidence of renal vasodilator activity was determined in anesthetized dogs by measuring the effects on renal blood flow and calculating the accompanying changes in renal vascular resistance. The most potent compounds contained, in their basic structure, the L-prolyl-DL-alpha-methylphenylalanyl-L-arginine and L-prolyl-DL-alpha-methylphenylalanylglycyl-L-proline arrays. Substitution on the N-terminal proline with 4-phenylbutyryl and 4-(4-hydroxyphenyl)butyryl side chains produced enhanced renal vasodilator activity and, in certain cases, selectivity for the renal vasculature.

  trazolylpyrrolidines were studied as prolyl oligopeptidase inhibitors. The compounds were more potent than expected from the assumption that the tetrazole would also here be a bioisostere of the carboxylic acid group and the corresponding carboxylic acids are at their best only weak inhibitors. The aminoacyl groups l-prolyl and l-alanyl gave potent inhibitors with IC50 values of 12 and 129 nM, respectively

  研究了4-苯基丁酰基-氨基酰基-2（S）-四唑基吡咯烷酮作为脯氨酰寡肽酶抑制剂。从四唑也将是羧酸基团的生物等排体并且相应的羧酸在其最佳状态下仅是弱抑制剂的假设出发，这些化合物比预期的更有效。氨酰基1-脯氨酰基和1-丙氨酰基产生了有效的抑制剂，IC50值分别为12和129 nM。这与典型的脯氨酰寡肽酶抑制剂是一致的。但是，我们确实观察到了与N-甲基-1-丙氨酰的区别，后者在典型的脯氨酰寡肽酶抑制剂中提供了有效的抑制剂，但在我们的新型化合物系列中却没有。此外，所有研究的4-苯基丁酰基-氨基酰基-2（S）-四唑基吡咯烷酮在10μM的浓度下均会降低α-突触核蛋白的二聚作用，当它们只是酶的蛋白水解活性的弱抑制剂时，IC50值为205μM。分子对接研究表明，与本研究中以4-苯基丁酰基-氨基酰基-2（S）-氰基吡咯烷酮为代表的典型脯氨酰寡肽酶抑制剂相比，该化合物与酶的结合方式可能不同。

  By chemical modification of a known prolyl endopeptidase (PEP) inhibitor (N-[N-(4-phenylbutanoyl)-L-prolyl]pyrrolidine; SUAM-1221), several arylalkanoyl derivatives (V-1-27) were synthesized and tested for in vitro inhibitory activity towards PEP from canine brain. Among them, 4-(2-thienyl)butanoyl derivatives (V-24-27) showed more potent PEP-inhibitory activity than SUAM-1221. The structure-activity relationships of these compounds are discussed.

  通过对一种已知的脯氨酰内肽酶（PEP）抑制剂（N-[N-（4-苯基丁酰基）-L-脯氨酰]吡咯烷；SUAM-1221）进行化学修饰，合成了几种芳基烷酰基衍生物（V-1-27），并测试了其对犬脑中 PEP 的体外抑制活性。其中，4-（2-噻吩基）丁酰衍生物（V-24-27）显示出比 SUAM-1221 更强的 PEP 抑制活性。本文讨论了这些化合物的结构-活性关系。

  Different five-membered nitrogen-containing heteroaromatics in the position of the typical electrophilic group in prolyl oligopeptidase (PREP) inhibitors were investigated and compared to tetrazole. The 2-imidazoles were highly potent inhibitors of the proteolytic activity. The binding mode for the basic imidazole was studied by molecular docking as it was expected to differ from the acidic tetrazole

  研究了脯氨酰寡肽酶 (PREP) 抑制剂中典型亲电子基团位置的不同五元含氮杂芳烃，并将其与四唑进行了比较。2-咪唑是蛋白水解活性的高效抑制剂。通过分子对接研究碱性咪唑的结合模式，因为它预计与酸性四唑不同。对于 2-咪唑，发现了一种与 His680 相互作用的新假定非共价结合模式。蛋白水解活性的抑制与对 PREP 的蛋白质-蛋白质相互作用衍生功能（即 α-突触核蛋白的二聚化和自噬）的调节作用无关。在抑制 2-咪唑的高效 PREP 中，只有一种也是 PREP 催化的 α-突触核蛋白二聚化的有效调节剂，
