简介内容:SS47, a PROTAC -based HPK1 degrader , exerts proteasome-mediated HPK1 degradation. The degradation of HPK1 via SS47 also significantly enhances the?in?vivo?antitumor efficacy of BCMA CAR-T cell research. HPK1, an?immunosuppressive?regulatory kinase, is a promising target for cancer immunotherapies [1] .
