dBET1

dBET1 is a CRBN-based BET degrader with an IC50 of 20 nM, showing highly selectivity. Out of 7,429 proteins, only the expression of the oncoproteins MYC and PIM1, as well as BRD2, BRD3 and BRD4 are significantly downregulated by dBET1 treatment.

Treatment with dBET1 elicits a comparable, modest effect on MYC and PIM1 expression. Its treatment downregulates MYC and PIM1 transcription, suggestive of secondary transcriptional effects and transcription of BRD4 and BRD3 are unaffected, consistent with post-transcriptional effects. Transcription of BRD2 is affected by dBET1 and protein stability of the BRD2 gene product is influenced by dBET1. dBET1 induces a potent and superior inhibitory effect on MV4;11 cell proliferation at 24 hours (measured by ATP content, IC50 = 0.14 μM). Exposure of primary leukemic patient blasts to dBET1 elicits dose-proportionate depletion of BRD4 and induction of apoptosis[1]. dBET1-mediated targeted degradation of BET proteins robustly dampens pro-inflammatory responses in LPS-stimulated microglia, that is, depletion of BRD2 and BRD4 with dBET1 is associated with dramatically reduced LPS-induced COX-2 and iNOS protein levels and pro-inflammatory gene transcription of Nos2, Il-1β, Il-6, Tnfα, Ccl2, Ptgs2, and Mmp9[2].

Administration of dBET1 attenuates tumor progression and decreases tumor weight assessed post-mortem in murine xenograft model of human MV4;11 leukemia cells. Pharmacokinetic studies of dBET1 (50 mg/kg IP) corroborate adequate drug exposure in vivo (Cmax = 392 nM, Tmax=0.5 hr, terminal t1/2=6.69 hr, AUClast=2109 hr*ng/ml, AUCINF=295 hr*ng/ml). Two weeks of dBET1 is well tolerated by mice without a meaningful effect on weight, white blood count, hematocrit or platelet count[1].

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.
