    Development of peptidyl α-keto-β-aldehydes as new inhibitors of cathepsin L — comparisons of potency and selectivity profiles with cathepsin B
    摘要:
    We have utilized previously known substrate and inhibitor specificity profiles for the lysosomal cysteine protease, cathepsin L, to design a new series of putative inhibitors of this enzyme, based on di- and tri-peptidyl alpha-keto-beta-aldehydes. Kinetic evaluation of those compounds revealed Z-Phe-Tyr(OBut)-COCHO, with a K-i=0.6 nM, to be the most potent, synthetic reversible inhibitor of cathepsin L reported to date.

    游离和结合亮肽素类似物的抑制特性
    摘要:
    亮肽素是各种蛋白酶,特别是丝氨酸蛋白酶的天然抑制剂。在发现之后,研究了其他几种肽基精氨酸的抑制特性。亮抑酶肽的特异性最有可能是由于 Leu-Leu-精氨酸序列,其 C 端醛基被认为可以提高结合效率并对功能至关重要。末端醛基使结构不易受到羧肽酶的影响。在这里,我们研究了亮抑酶肽对丝氨酸蛋白酶的抑制功能在醛基氧化或还原后是否保留。与天然前体相对应的氧化形式在抑制特性方面优于还原形式。然而,与氧化形式相比,原始亮抑酶肽具有增强的抑制特性。基于这些结果,使用 Fmoc 策略通过固相肽合成制备了新的合成亮肽素类似物,6-氨基己酸 (Ahx)-Phe-Leu-Arg-COOH 和 Ahx-Leu-Leu-Arg-COOH。在这些类似物中,N 端的乙酰基被 6-氨基己酰基取代以允许结合。修饰的亮抑酶肽和合成肽的结构通过质谱法确认。对胰蛋白酶抑制特性的测定(IEC 3.4.21.4,糜蛋白酶 IEC 3.4
