Small molecule inhibitors have dominated the pharmaceutical landscape for a long time as the primary therapeutic paradigm targeting pathogenic proteins.However,their efficacy heavily relies on the amino acid composition and spatial constitution of proteins,rendering them susceptible to drug resistance and failing to target undruggable proteins.In recent years,the advent of targeted protein degradation(TPD)technology has captured substantial attention from both industry and academia.Employing an event-driven mode,TPD offers a novel approach to eliminate pathogenic proteins by promoting their degrada-tion,thus circumventing the limitations associated with traditional small molecule inhibitors.Hydropho-bic tag tethering degrader(HyTTD)technology represents one such TPD approach that is currently in the burgeoning stage.HyTTDs employ endogenous protein degradation systems to induce the degrada-tion of target proteins through the proteasome pathway,which displays significant potential for medical value.In this review,we provide a comprehensive overview of the development history and the reported mechanism of action of HyTTDs.Additionally,we delve into the physiological roles,structure-activity re-lationships,and medical implications of HyTTDs targeting various disease-associated proteins.Moreover,we propose insights into the challenges that necessitate resolution for the successful development of HyTTDs,with the ultimate goal of initiating a new age of clinical treatment leveraging the immense po-tential of HyTTDs.
