OTX015

Описание

The bromodomain and extra terminal domain (BET) family of proteins, including BRD2, BRD3, and BRD4, play a key role in many cellular processes, including inflammatory gene expression, mitosis, and viral/host interaction by controlling the assembly of histone acetylation-dependent chromatin complexes. OTX015 is an orally bioavailable, small molecule inhibitor of BRD2, BRD3, and BRD4 (EC₅₀s = 10-19 nM). It displays antiproliferative effects at a sub-micromolar range in vitro in a wide range of solid tumor types and leukemias, downregulating c-Myc expression and inducing cell cycle arrest and apoptosis. At 100 mg/kg, OTX015 has been shown to inhibit the growth of Ty82 BRD-NUT midline carcinoma tumors in nude mice by 79%.

(S)-2-(4-(4-Chlorophenyl)-2,3,9-trimethyl-6H-thieno[3,2-f][1,2,4]triazolo[4,3-a][1,4]diazepin-6-yl)-N-(4-hydroxyphenyl)acetamide is an orally bioavailable, inhibitor of BRD2, BRD3, and BRD4 to AcH4 and shows anti-tumor activity in vitro and in vivo tumor models.

Биохимия/физиол Действия

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.
