A series of inhibitors targeting human cathepsins have been designed and synthesized following a combinatorial approach. The compounds bear an α,β-unsaturated phenyl vinyl sulfone or ethyl acrylate warhead and a peptidomimetic portion aligned to the non-primed binding region. Biochemical evaluation toward four human cathepsins was carried out and the kinetic characterization confirmed an irreversible
按照组合方法已经设计和合成了一系列靶向人组织蛋白酶的抑制剂。该化合物带有α,β-不饱和苯基乙烯基砜或丙烯酸乙酯战斗部,其拟肽部分与非引发的结合区域对齐。对四种人组织蛋白酶进行了生化评估,动力学表征证实了不可逆的抑制模式。结合了抑制组织蛋白酶S的最有利结构单元的化合物6c被鉴定为有效的组织蛋白酶S失活剂,其二级速率常数为30600 M-1 s-1。
