PROTAC(Proteolysis Targeting Chimera)技术,即蛋白降解靶向嵌合体技术,是一种全新的药物研发策略。该技术通过利用细胞内天然的蛋白降解体系——泛素蛋白酶体系统(UPS),实现对目标蛋白(POI,protein of interest)的特异性降解。 PROTAC分子由三个主要部分组成:靶蛋白配体、连接子(Linker)和E3连接酶配体。靶蛋白配体能够...
转发:PROTAC(Proteolysis-targeting chimera)全称蛋白降解靶向嵌合体,即利用泛素-蛋白酶体系统诱导靶向蛋白降解。与传统小分子药物不同,PROTAC无需与目标蛋白长时间和高强度的结合,便可捕获蛋白并将其降解,因此有望突破传统难以成药的靶点并克服耐药性问题。 PROTAC作为一项全新的小分子药物技术,可作用于传统靶向药物无...
每日一学:蛋白质水解靶向嵌合体(Proteolysis Targeting Chimera, PROTAC)技术应运而生。PROTAC就是靶向蛋白降解的小分子联合体,联合体分子包括三部分:一头是靶向目标蛋白的结构;另一头是可以招募蛋白降解体系比如E3连接酶的结构;中间则通过合适的连接器(linker)连接!蛋白降解疗法形象的比喻为给癌基因添加了叛军的标签,...

Proteolysis targeting chimeras (PROTACs) are heterobifunctional small molecules that utilize the ubiquitin proteasome system (UPS) to degrade proteins of interest (POI). PROTACs are potentially superior to conventional small molecule inhibitors (SMIs) be
Proteolysis-targeting chimera (PROTAC) has been developed to be a useful technology for targeted protein degradation. A bifunctional PROTAC molecule consists of a ligand (mostly small-molecule inhibitor) of the protein of interest (POI) and a covalently linked ligand of an E3 ubiquitin ligase (E3...
