产品详情
生物活性:
Birabresib (OTX-015) is a potent bromodomain (BRD2/3/4) inhibitor with IC50s ranging from 92 to 112 nM.

体内研究:
In MDA-MB-231 murine xenografts, tumor mass is significantly (p?< 0.05) reduced by Birabresib (OTX-015) (50 mg/kg) with respect to vehicle-treated animals. Birabresib (OTX-015) in combination with 2 mg/kg RAD001 shows more effective activity than Birabresib alone.

体外研究:
Birabresib (OTX-015) (500 nM) exposure induces a strong decrease of BRD2, BRD4 and c-MYC and increase of HEXIM1 proteins, while BRD3 expression is unchanged. c-MYC, BRD2, BRD3, BRD4?and?HEXIM1?mRNA levels do correlate however with viability following exposure to Birabresib (OTX-015).?Birabresib (OTX-015) (0.1, 1, 5 μM) treatment induces HIV-1 full-length transcripts and viral outgrowth in resting CD4+ T cells from infected individuals receiving suppressive antiretroviral therapy (ART), while exerting minimal toxicity and effects on T cell activation. Birabresib-mediated activation of HIV-1 involves an increase in CDK9 occupancy and RNAP II C-terminal domain (CTD) phosphorylation.
