    生物活性

    Birabresib (OTX-015) is a potent bromodomain (BRD2/3/4) inhibitor with IC50s ranging from 92 to 112 nM.

    IC50 & Target

    IC50: 92-112 nM (BRD2, BRD3, BRD4)[1]

    體外研究
    (In Vitro)

    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)[2].?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[3].

    MCE has not independently confirmed the accuracy of these methods. They are for reference only.

    體內(nèi)研究
    (In Vivo)

    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[4].

    Cell Assay
    [2]

    For the MTT assay, cells are seeded in 24-well plates at 1×106?per well and treated with Birabresib (OTX-015) (0.01 nM-10 μM) for 72 h. Cells are transferred to 96-well plates and incubated with 0.5 mg/mL 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) in the dark at 37°C for 4 h. Cells are then lysed with 25% sodium dodecyl sulfate (SDS) lysis buffer and absorbance is read at 570 nm using a Microplate Reader. Three independent experiments are run for each cell line and untreated cells are used as negative controls.

    MCE has not independently confirmed the accuracy of these methods. They are for reference only.

    Animal Administration
    [4]

    Mice are subcutaneously injected in the right flank with 10×106 MDA-MB-231 cells. When average tumor weight is appr 130 mg, mice are randomized (nine animals/group) to one of the following experimental groups: vehicle (for Birabresib (OTX-015), water, twice daily, oral; for RAD001 vehicle, 5% Tween-80/5% polyethylene glycol 400, thrice weekly, intraperitoneal); 50 mg/kg Birabresib (OTX-015), twice daily, oral; 2 mg/kg RAD001, thrice weekly, intraperitoneal; 50 mg/kg Birabresib (OTX-015) + 2 mg/kg RAD001, according to the single agent dosing schedules.

    Help & FAQs
    • Do most proteins show cross-species activity?

      Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
