series of azadipeptide nitriles with different P3 groups. A triaryl meta-phenyl derivative, compound 13, was not only a potent inhibitor for cathepsin K (Ki = 0.0031 nM), but also highly selective over both cathepsins B and S (∼1000-fold). A protein–ligand docking study performed on the series provided a possible explanation why compound 13 could be significantly more potent than the others, especially
我们开发了一系列具有不同P3基团的氮杂二肽腈。三芳基间苯基衍生物(化合物13)不仅是组织蛋白酶K的有效抑制剂(K i = 0.0031 nM),而且对组织蛋白酶B和S都具有很高的选择性(约1000倍)。在该系列上进行的蛋白质-配体对接研究提供了可能的解释,为什么化合物13可能比其他化合物更有效,尤其是同一系列中的化合物12。
