| 中文摘要:靶向蛋白降解技术（TPD）通过调动细胞内固有的两大蛋白降解机制——泛素-蛋白酶体系统（UPS）或溶酶体途径下调致病靶蛋白，有望克服传统抑制剂的局限性，挑战“难成药”靶点，为药物开发提供新的靶向治疗手段。重点关注多种有前景的靶向蛋白降解技术，包括蛋白水解靶向嵌合体（PROTAC）、分子胶、溶酶体靶向嵌合体（LYTAC）、自噬体绑定化合物（ATTEC）、自噬靶向嵌合体AUTAC和AUTOTAC，分析代表性的案例及其潜在的应用与挑战。 |

| Abstract:Targeted protein degradation (TPD) techniques eliminate pathogenic proteins by hijacking the intracellular proteolysis machinery which includes the ubiquitin-proteasome system (UPS) and the lysosomal degradation pathway, holding promise to overcome the limitations of traditional inhibitors and further broaden the target space including many “undruggable” targets, and provide new targeted treatments for drug discovery. In this review, recent advances in a variety of promising TPD strategies were summarized, such as proteolysis targeting chimera (PROTAC), molecular glue, lysosome-targeting chimaera (LYTAC), autophagosome-tethering compound (ATTEC), autophagy-targeting chimera AUTAC and AUTOTAC, particularly. The representative case studies, potential applications and challenges were analyzed. |
