Epigenetic Reader Domain Degrader

MMH1 is a novel BRD4 molecular glue degrader. MMH1 functions by recruiting the CUL4 DCAF16 ligase to the second bromodomain of BRD4 (BRD4 BD2). MMH1 binds to the JQ1-binding site of BRD4 BD2, acts as a template to covalently modify Cys58 of DCAF16, stabilizes the BRD4-DCAF16 ternary complex, and thereby promotes BRD4 degradation via the CRL4_DCAF16 ubiquitin ligase pathway. Using BRD4 BD2 as a structural template, MMH1 covalently modifies Cys87 of GAK and induces the GAK-BRD4 BD2 interaction. Through its covalent mechanism, MMH1 exhibits sustained BRD4 degradation activity, and shows selective degradation activity for BRD4 BD2 over BRD4 BD1.

BD-9136 is a selective BRD4 PROTAC degrader with a DC₅₀ of 1.2 nM, and exhibits a selectivity of ≥1000-fold over BRD2 and BRD3.

BD-9136 depletes BRD4 protein in tumor tissues, inhibits tumor growth, reduces B7-H4 protein expression, increases CD8+ T cell infiltration, and enhances tumor sensitivity to anti-PD-L1. Degradation of BRD4 by BD-9136 rescues the erythroid differentiation block induced by LSD1 inhibition, and transient administration restores erythroid output while retaining HbF induction. BD-9136 causes no adverse effects in mice at effective doses. BD-9136 can be used in studies related to acute myeloid leukemia, acute lymphoblastic leukemia and breast cancer.
