In vitro

dBET6 is a highly cell-permeable degrader of BET bromodomains. It is potent in most cancer cell lines. dBET6 features highly increased cellular potency with evident degradation in the sub-nanomolar range. Treatment with 100 nM dBET6 leads to degradation of BRD4 after 1 hr, prompting subsequent downregulation of c-MYC and induction of apoptosis. dBET6 disrupts global productive transcription elongation. dBET6 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[1].

In vivo

dBET6 is well tolerated. Upon dBET6 treatment, a significant reduction of leukemic burden is observed in a disseminated mouse model of T-ALL. Moreover, mice treated with dBET6 (7.5 mg/kg BID) exhibits a significant survival benefit compared to mice treated with vehicle control or JQ1 (20 mg/kg QD)[1].

Protocol (from reference)

Cell Research:


  • Cell lines: MOLT4 cells deficient in CRBN expression
  • Concentrations: 0.05, 0.1, 0.5, 1 μM
  • Incubation Time: 3 hr
  • Method:

    MOLT4 cells deficient in CRBN expression are treated with various concentrations of either dBET1 or dBET6 for 3 hr. Cells are collected by centrifugation, washed once with PBS and transferred into PCR tubes, spun down and incubated at 47.5°C for 3 min. After a subsequent incubation for 3 min on 25°C, cells are lysed by addition of 30 µL lysis buffer and three repeated freeze-thaw cycles using liquid nitrogen.

Animal Research:


  • Animal Models: Male CD-1 mice
  • Dosages: 10 mg/kg
  • Administration: i.p.

Working concentration: mg/ml;

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
