BI-3663 is a highly selective PTK2 FAK PROTAC that utilizes cereblon ligands to hijack E3 ligases for PTK2 degradation, with an IC50 of 18 nM. It is composed of BI-4464 linked to Pomalidomide with a linker[1]. Anti-cancer.
PROTAC BRD2 BRD4 degrader-1 (compound 15) serves as a potent, selective degrader of BET proteins BRD4 and BRD2, achieving rapid, reversible, and unexpectedly selective elimination of BRD4 and BRD2 compared to BRD3. Its efficacy in suppressing solid tumors manifest with minimal cytotoxic effects. This compound comprises a BET inhibitor, a connecting linker, and thalidomide as the ligand for cereblon (CRBN) cullin 4A[1].
