Background | Apabetalone is a potent BET bromodomain inhibitor that acts on BD2. |
Biological Activity | Apabetalone (RVX-208) 是一种 BET 转录抑制剂,作用于 BD1 和 BD2,IC50 分别为 87±10 μM 和 0.51±0.041 μM。[1-3] |
IC50 | 510±41nM(BD2),87±10μM(BD1)[1] |
In Vitro | Apabetalone(RVX-208)与乙酰化组蛋白肽与四种BET蛋白的串联BD1 BD2蛋白构建体的结合竞争,IC50介于0.5和1.8μM之间。 Apabetalone在体外增加肝细胞中ApoA-I的产生,这导致高密度脂蛋白胆固醇(HDL-C)的增加。 Apabetalone选择性地结合BET(Bromodomain和Extra Terminal)家族的溴结构域,竞争由内源配体,乙酰化赖氨酸结合的位点,并且这解释了其药理学活性。 Apabetalone通过表观遗传机制增加载脂蛋白AI(ApoA-I)的产生,并表明BET抑制可能是治疗动脉粥样硬化的一种有前途的新方法。 Apabetalone增加肝细胞中ApoA-I的表达[2]。 |
In Vivo | 在动脉粥样硬化预防性治疗研究设计中,给小鼠喂食西方饮食,同时以150mg / kg /剂量bid治疗12周。处理后12周处死小鼠。在所治疗的媒介物以及Apabetalone(RVX-208)治疗组中,体重逐渐增加。然而,在Apabetalone治疗组的西方饮食12周后,体重仅增加4g(从24g到28g),而在车辆中发现这种增加为9g(25g-34g)。治疗组。 Apabetalone处理的小鼠体重增加显著减少不是由于饲料消耗减少,这表明该分子的正面属性。在用载体或Apabetalone处理6周和12周时进行血浆脂质测量。与载体对照动物相比,Apabetalone处理的小鼠在治疗6周时显示HDL-C水平显著增加(~200%),持续至研究结束(12周)[3]。 |
Cell Experiment | 将Huh7细胞以23,000 /孔接种在96孔板中的DMEM + 10%FBS中,然后使其生长过夜。将细胞用化合物在含有或不含有5μM放线菌素D的0.1%DMSO中处理48小时.U937细胞在60ng / mL PMA中分化3天,以96孔形式在32,000细胞/孔中分化。然后用在0.1%DMSO中的化合物在RPMI培养基+ 10%FBS中处理细胞,1小时后,将脂多糖以1μg/ mL加入细胞中3小时[2]。 |
Animal Experiment | 小鼠[3]使用七至八周大的雄性ApoE - / - 小鼠。根据体重和脂质值,将小鼠分为2组(n = 12):第1组,载体;和第2组,测试代理,Apabetalone。然后将小鼠转换为西方饮食(0.15%胆固醇和42%卡路里的脂肪)并同时通过管饲法用载体或试验药物Apabetalone(150mg / kg /剂量bid)口服治疗12周。治疗6周后,进行中期抽血以监测血清脂质水平。处理12周后,处死小鼠以测量血脂参数,主动脉损伤以及肝和主动脉RNA。 8只小鼠用于enface(主动脉斑块)分析,4只小鼠用于组织收集mRNA,所有12只小鼠用于主动脉窦病变区域测量。 |
