Description
本发明属于医药技术领域,涉及一类靶向蛋白质水解通路的功能分子及其制备和应用,以及其药学上可接受的盐和其药学组合物在治疗肿瘤中的应用。本发明通过使用连接臂将含有过氧桥键的化合物和E3泛素连接酶复合体中的小分子配体连接获得功能化小分子,属于医药技术领域。
泛素-蛋白酶体途径(ubiquitin proteasome pathway,UPP)是细胞内蛋白质降解的主要途径。泛素-蛋白酶体途径由泛素、泛素活化酶E1、泛素结合酶E2、泛素连接酶E3、蛋白酶体及其底物(蛋白质)构成。泛素-蛋白酶体途径特异性降解蛋白质时,首先发生酶催化的蛋白底物泛素化。随后,被泛素化的蛋白分子能够被蛋白酶体识别,并进入蛋白酶体体降解成短链的多肽分子,发生蛋白底物降解。这个蛋白降解系统能够清除老化或者受损蛋白,对维持正常的细胞动态平衡和生理功能发挥重要的作用。
