SS47 TFA
SS47 TFA is a PROTAC-based degrader targeting hematopoietic progenitor kinase 1 (HPK1), an immunosuppressive regulatory kinase. It induces proteasome-mediated degradation of HPK1 and significantly enhances the antitumor efficacy of BCMA CAR-T cell therapy in vivo. In addition to its biological function, SS47 TFA is also a click chemistry reagent containing an alkyne group, allowing it to participate in copper-catalyzed azide–alkyne cycloaddition (CuAAC) with azide-functionalized molecules. This dual functionality makes SS47 TFA a valuable tool in both cancer immunotherapy research and chemical biology applications.
