Description SB408124 is a non-peptide antagonist for OX1 receptor with Ki of 57 nM and 27 nM in both whole cell and membrane, respectively, exhibits 50-fold selectivity over OX2 receptor.
In vitro SB-408124与下丘脑促觉醒素1型受体(HcrtR1)结合,具有7.57的pKi值。通过钙离子动员研究表明,SB-408124是OX1受体的功能性拮抗剂,相对于OX2受体具有大约50倍的选择性。最近的研究指出,施予大鼠星形胶质细胞原代培养前用SB-401824处理,可以显著降低Orexin A对于基础状态及forskolin激活的cAMP产生的刺激作用。
In vivo SB-408124(30 μg/10 μL,经脑室内给药)能降低Wistar大鼠因Orexin-A诱导的饮水量。脑室内给药的Orexin-A(30 μg/10 μL)能阻断由组胺或2.5% NaCl给药引起的加压素(VP)水平上升,SB-408124的预处理可以缓和这一阻断效果。[3] 脑室内预处理SB-408124(50 mM, 5 μL/h)可防止Bicuculline(BIC)引起的内源性葡萄糖产生(EGP)增加。[4]
