PROTAC FAK degrader 3

PROTACFAKdegrader 3 is a selective FAK PROTAC degrader (DC50 = 1.08 nM) . It induces FAK degradation through the ubiquitin-proteasome system and its interaction with FAK and CRBN. By inhibiting FAK's non-catalytic activity, PROTACFAKdegrader 3 enhances MHC-I gene transcription and tumor cell surface expression, leading to increased antigen presentation and activation of cytotoxic CD8 T cells. Its ability to promote MHC-I expression and boost T cell activation strengthens its antitumor efficacy in vivo. PROTACFAKdegrader 3 is applicable to cancer research targeting FAK degradation, including studies on ovarian cancer and hepatocellular carcinoma.
