I have found the logs that report the error in the docker container. After that I do an internet search dBET1 functions by selectively binding the BET bromodomain and recruits the cereblon-CUL4 ubiquitin ligase complex, leading to BET ubiquitination and.

HEK293 cells were transfected with NanoLuc®-BRD4 and HaloTag®-Ubiquitin plasmids at a 1:100 donor:acceptor ratio, plated in the presence of HaloTag® NanoBRET™ 618 Ligand, and treated with a serial dilution of 10μM dBET1 or MZ1 PROTAC compounds for 1 hour. For both PROTACs, a dose-dependent increase in BRET ratio was observed.

dBET1 treatment down regulates MYC and PIM1 transcription. dBET1 also induces a potent and superior inhibitory effect on MV4;11 cell proliferation at 24 hours (measured by ATP content, IC50= 0.14 μM, compare to IC50= 1.1 μM with JQ1).

Selective degradation of BET proteins with dBET1, a proteolysis-targeting chimera, potently reduces pro-inflammatory responses in lipopolysaccharide-activated microglia Selective degradation of BET proteins with dBET1, a proteolysis-targeting chimera, potently reduces pro-inflammatory responses in lipopolysaccharide-activated microglia dBET1 dBET1 is a potent and selective BRD4 protein degrader. The molecule, dubbed “degronimid”, is harnessed by combining two specific high affinity protein ligands, (+)-JQ1 for BRD4 and Phthalimide for E3 ubiquitin ligase cereblon (CRBN), tethered by a linker. View and buy high purity dBET1. (+)-JQ1 based PROTAC targeting BET bromodomains, active in vivo. The resultant compound, dBET1, induced highly selective cereblon-dependent BET protein degradation in vitro and in vivo and delayed leukemia progression in mice. A second series of probes resulted in selective degradation of the cytosolic protein FKBP12.

1 The JQ1 portion facilitates binding of dBET1 to the bromodomains of BET family transcriptional activators. dBET1 is a potent BRD4 protein degrader based on PROTAC technology with an EC50 of 430 nM. Jul 01, 2019 · dBET1, a proteolysis targeting chimera, degrades BET protein BRD4 in the brain. View and buy high purity dBET1 from Tocris Bioscience. (+)-JQ1 based PROTAC targeting BET bromodomains, active in vivo. dBET1, a proteolysis targeting chimera, degrades BET protein BRD4 in the brain. May 29, 2018 · Comparative study among three BET degraders (dBET1, dBET6, and ARV-825) showed further that equimolar dBET6 was more efficient than the other two to reduce BRD4 (SI Appendix, Fig. S3I).

8. 0.0001. 0.001. 0.01. 0.1. 1. NL-BRD4 HEK293 Stable.

For both PROTACs, a dose-dependent increase in BRET ratio was observed. Besides, dBET1 exhibited greater apoptosis induction than JQ1 both in AML cell-based assays and in a murine xenograft model of AML . Similar to dBET1, another PROTAC coupling OTX015 and pomalidomide, named ARV-825, was discovered to induce the almost-complete degradation of BRD4 at 10 nM in 6 h . Further studies indicated that ARV-825 is Nov 29, 2018 · By contrast, dBET1 induced apoptosis in CML LSC at 1 µM and dBET6 induced apoptosis in CML LSC at 0.1 µM. dBET6 induced apoptosis in CML LSC obtained from patients with imatinib-sensitive CML as well as patients with imatinib-resistant CML harboring BCR-ABL1 T315I or BCR-ABL1 F317L. were incubated in 10-ul reaction with 100 nM dBET1 and 15 nM GST-BRD3 BPS #31033 at room temperature for one hour.
