FKBP12 ligand-2

FKBP12 ligand-2 (compound d) is a high affinity ligand targeting FKBP12. FKBP12 ligand-2 can be used to selectively enhance the binding of heterobifunctional molecules to BRD4, enriching the drug intracellularly through the "CellTrap" effect to form a ternary complex of FKBP12-ligand-BRD4. This ternary complex has inhibitory activity against BRD4, thereby inhibiting the expression of BRD4 target genes (such as MYC) and inducing tumor cell death. FKBP12 ligand-2 can be used for selective cancer research based on differences in intracellular presenter protein levels[1].
