Mechanism of Action

Targets/IC₅₀/Ki	BRD4 14 nM
In vitro	dBET6 is a highly cell-permeable degrader of BET bromodomains. It is potent in most cancer cell lines. This compound features highly increased cellular potency with evident degradation in the sub-nanomolar range. Treatment with 100 nM of this chemical leads to degradation of BRD4 after 1 hr, prompting subsequent downregulation of c-MYC and induction of apoptosis. It disrupts global productive transcription elongation. Its treatment leads to a widespread decrease in steady-state mRNA levels, but observed an incommensurate impact on expression of members of the core regulatory circuitry of leukemogenic transcription factors. The collapse of the core transcriptional machinery prompted by BET degradation precedes a robust apoptotic response, of apparent translational significance.
In vivo	dBET6 is well tolerated. Upon treatment with this compound, a significant reduction of leukemic burden is observed in a disseminated mouse model of T-ALL. Moreover, mice treated with this chemical (7.5 mg/kg BID) exhibits a significant survival benefit compared to mice treated with vehicle control or JQ1 (20 mg/kg QD).
