The design and synthesis of dipeptidyl disulfides and dipeptidyl benzoylhydrazones as selective inhibitors of the cysteine protease Cathepsin S are described. These inhibitors were expected to form a slowly reversible covalent adduct of the active site cysteine of Cathepsin S. Formation of the initial adduct was confirmed by mass spectral analysis. The nature and mechanism of these adducts was explored
描述和设计和合成作为半胱氨酸蛋白酶组织蛋白酶S的选择性抑制剂的二肽基二硫化物和二肽基苯甲酰基hydr。预期这些抑制剂会形成组织蛋白酶S活性位点半胱氨酸的缓慢可逆的共价加合物。通过质谱分析证实了初始加合物的形成。探索了这些加合物的性质和机理。苯甲酰的动力学分析表明,这些抑制剂可作为组织蛋白酶S的不可逆抑制剂。此外,已证明苯甲酰shown在体外和体内均是组织蛋白酶S处理II类相关不变肽的有效抑制剂。
