生物活性

产品描述	一种有效的BET bromodomain抑制剂，靶向BRD2/3/4，EC50范围为10nM到19nM。
靶点/IC50	BRDs (Cell-free assay)
靶点/IC50	10-19nM(EC50)
体外研究	Birabresib (OTX-015) (500nM) 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) (0.1,1,5μM) treatment induces HIV-1 fulllength 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.
体内研究	In MDA-MB-231 murine xenografts,tumor mass is significantly (p<0.05) reduced by Birabresib (OTX-015) (50mg/kg) with respect to vehicle-treated animals.Birabresib (OTX-015) in combination with 2mg/kg RAD001 shows more effective activity than Birabresib alone.

推荐实验方法(仅供参考)

激酶实验：

TR-FRET 试验

为了评估OTX015与BRD2，BRD3，以及BRD4的结合，BRD表达的CHO细胞裂解物(来自感染表达质粒的CHO细胞， Flag标记的BRD2，BRD3，或BRD4 或仅载体)，铕共轭的抗Flag抗体，XL-665共轭的链霉亲和素，和生物素化的OTX015在室温下培育0.2到2小时。荧光性通过TR-FRET使用EnVision 2103多标阅读器测量，结合的EC50使用5.02版PRISM通过非线性回归计算。

细胞实验:

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

动物实验:

Mice are subcutaneously injected in the right flank with 10×106 MDA-MB-231 cells.When average tumor weight is appr 130mg,mice are randomized (nine animals/group) to one of the following experimental groups:vehicle (for Birabresib (OTX015),water,twice daily,oral;for RAD001 vehicle, 5% Tween-80/5% polyethylene glycol 400,thrice weekly,intraperitoneal);50mg/kg Birabresib (OTX-015),twice daily,oral;2mg/kg RAD001,thrice weekly,intraperitoneal;50mg/kg Birabresib (OTX015) +2mg/kg RAD001,according to the single agent dosing schedules.
