AWD 131-138是一种苯二氮受体的部分激动剂[1]。
苯二氮(BZD)是一种神经药物,是一种抑制性神经递质GABA的正向别构调节剂,可结合GABAA受体氯离子载体复合物的识别位点(BZD受体)[1]。
AWD 131-138是一种苯二氮受体的部分激动剂,具有抗惊厥和抗焦虑活性[1]。在表达重组γ-氨基丁酸A(GABAA)受体ɑ1β2γ2、ɑ1β3γ2、ɑ2β2γ2、ɑ3β2γ2和ɑ5β2γ2的非洲爪蟾卵母细胞中,AWD 131-138可以剂量依赖的方式刺激GABA电流,并作用于苯二氮卓的结合位点。AWD 131-138(10 μM)可刺激GABA电流,是地西泮达到的最大刺激值的12-21%[2]。
在狗惊厥模型中,AWD 131-138可提高戊四唑(PTZ)的惊厥临界值。AWD 131-138(5或40 mg/kg)可引起相对温和的戒断症状,尤其是在低剂量时。在新诊断为癫痫的狗中,AWD 131-138可显著降低惊厥的频率和严重程度[3]。
