  Human cathepsin B (CatB) is an important biological target in cancer therapy. In this work, we performed a knowledge-based design approach and the synthesis of a new set of 19 peptide-like nitrile-based cathepsin inhibitors. Reported compounds were assayed against a panel of human cysteine proteases: CatB, CatL, CatK, and CatS. Three compounds (7h, 7i, and 7j) displayed nanomolar inhibition of CatB

  人组织蛋白酶 B (CatB) 是癌症治疗中的重要生物学靶点。在这项工作中，我们采用了一种基于知识的设计方法，并合成了一组新的 19 种肽样腈基组织蛋白酶抑制剂。针对一组人半胱氨酸蛋白酶对报告的化合物进行了分析：CatB、CatL、CatK 和 CatS。三种化合物（7h、7i和7j）显示出对 CatB 的纳摩尔抑制以及对 CatK 和 CatL 的选择性。的选择性通过使用的组合来实现对位联苯环在P 3，卤代苯丙氨酸P 2和Thr-O-BZ组在P 1。同样地，化合物7I和7J在所研究的酶组中显示出选择性 CatB 抑制作用。我们还描述了一个成功的例子，用生物等排置换磺酰胺 [ 7e  →  6b ]的酰胺键，我们观察到 CatB 的亲和力和选择性增加，同时降低了化合物的亲脂性 (ilogP)。我们基于知识的设计方法和各自的结构-活性关系为治疗相关组织蛋白酶的特定配体-靶标相互作用提供了见解。
