BRD4/FKBP12 ligand 2
BRD4/FKBP12 ligand 2 is a heterobifunctional BRD4 and FKBP12 (Kd of 1.0 nM) ligand. BRD4/FKBP12 ligand 2 has positive cooperativity in BRD4 binding when pre-bound to FKBP12, and FKBP12-dependent cytotoxicity in cancer cells via the CellTrap effect. BRD4/FKBP12 ligand 2 can be used for the research of hematopoietic malignancy, multiple myeloma, prostate carcinoma, acute myeloid leukemia.
