Cell Proliferation Assay Cell Line: H929 cells Concentration: 100nM Incubation Time: 72 hours Result: Caused a significant dose- and time-dependent decrease in the proportion of myeloma cells in S/G2 phase. 体内研究 -BET151 demonstrates low blood clearance in the rat (~20% liver blood flow) and good oral systemic exposure which resulted in good oral bioavailability.High clearance is observed in the dog (~95% liver blood flow).The systemic exposure in the dog is low,resulting in a poor oral bioavailability of 16%.The high blood clearance in dog correlates well with the high intrinsic clearance observed in dog microsomes and hepatocytes,whereas the low intrinsic clearances seen in rat and mouse (mouse IVC 1.6mL/min/g;CLb 8mL/min/kg) correlate with lower in vivo blood clearances in these species.Due to the low systemic exposure observed in the dog,I-BET151 is investigated in the mini-pig as a potential second species for toxicological evaluation where it showed low clearance (~32% liver blood flow) and good bioavailability (65%).I-BET151 (30mg/kg;i.p.;daily for 21 days)-treats mice has four- to five fold smaller myeloma tumors and a significantly reduces rate of tumor size doubling than vehicle-treated mice. Animal Model: Mice (model of subcutaneous myeloma) Dosage: 50mg/kg Administration: I.p.; daily for 21 days Result: Reduced rate of tumor size doubling than vehicle-treated mice. 推荐实验方法(仅供参考) 激酶实验: 荧光各向异性(FP)的配体位移检测 所有组分溶解在50mM HEPES pH 7.4,150mM NaCl和 0.5mM CHAPS组成的Buffer中,BRD 2/3/4终浓度为75nM,荧光配体为5nM。在Greiner 384孔黑色的低量微孔板中,使用Micro Multidrop 将10μL反应混合物加入到含100nL各种浓度I-BET151或DMSO空白对照(1%最终)的孔中,并在黑暗中室温下平衡60分钟。使用 Envision (lex=485nm,lEM=530nm;Dichroic=505nM)读取荧光各向异性。 细胞实验: 细胞系 MV4;11,MOLM13,NOMO1,RS4;11,HEL,HL60 和 K562 浓度 溶于DMSO,终浓度为~100μM 处理时间 24,或72小时 方法 使用多种不同浓度I-BET151在384孔或96孔板中处理细胞24或72小时。细胞生长抑制实验中,实验板每孔中加入与细胞培养基同等体积的CellTiter-Glo试剂,震荡约2分钟,然后在Analyst GT 或EnVision酶标仪上读取化学发光信号。细胞增殖实验中,每孔加入CellTiter-Aqueous One,然后实验板在37°C下温育4小时。在SpectraMax Gemini酶标仪上490 nm处读取吸光度。 动物实验: 动物模型 静脉注射MV4;11细胞的NOD-SCID小鼠,静脉注射MLL-AF9细胞的C57BL/6小鼠 剂量 ~30mg/kg/day 给药处理 腹腔注射 |
