warheads. In this study, we have carried out a systematic investigation of described electrophiles by a combination of in vitro, in vivo, and structural methods in order to disclose the implications of altered functionality and chemical reactivity. Thereby, we were able to introduce and characterize the class of α‐ketoamides as the most potent reversible inhibitors with possible applications for the therapy
遍在蛋白-蛋白酶体系统(UPS)已被学术界和制药业成功地靶向用于肿瘤学和免疫学领域。典型的蛋白酶体抑制剂基于肽骨架,该肽骨架具有亲电的C末端,通过它们可与活性蛋白水解位点发生反应。尽管肽部分在亚基选择性方面引起了广泛关注,但化合物的靶标特异性和生物稳定性在很大程度上由反应性战斗部决定。在这项研究中,我们已经通过结合体外,体内和结构方法对亲电子试剂进行了系统的研究,以揭示功能和化学反应性改变的含义。从而,
