| Questions And Answer | Back Directory | [Description]
OTX015 is a potent BET bromodomain inhibitor with EC50 ranging from 10 to 19 nM for BRD2, BRD3, and BRD4 in cell-free assays. Phase 1. | [Features]
Orally bioavailable BRD2/3/4-selective inhibitor that has been tested in Phase I clinical trials for treatment of Haematological Malignancies. | [In vitro]
OTX015 inhibits the binding of BRD2, BRD3, and BRD4 to AcH4 with IC50 ranging from 92 to 112 nM, and inhibits the growth of a variety of human cancer cell lines with GI50 ranging from 60 to 200 nM. OTX015 results in rapid down-regulation of c-MYC expression, and show the synergistic anti-proliferative effects in combination with ALK inhibitors in ALKpos ALCL cell lines.
| [In vivo]
OTX015 (p.o.) significantly inhibits the growth of Ty82 BRD-NUT midline carcinoma tumors in nude mice by 79% at 100 mg/kg qd and 61% at 10 mg/kg bid, respectively.

ChEBI: 6h-thieno[3,2-f][1,2,4]triazolo[4,3-a][1,4]diazepine-6-acetamide, 4-(4-chlorophenyl)-n-(4-hydroxyphenyl)-2,3,9-trimethyl-, (6s)- is an organonitrogen heterocyclic compound and an organosulfur heterocyclic compound. | [Biochem/physiol Actions]
It binds to bromodomain and extra-terminal domain (BET) proteins and inhibits their binding to the chromatin. This in turn prevents gene transcription. OTX015 has been shown to inhibit proliferation of cells in haematological malignancies. | [target]
