中文名 1,2-二氢-N-[(3-内)-8-[(2R)-2-羟基-3-[甲基(甲磺酰基)氨基]丙基]-8-氮杂双环[3.2.1]辛-3-基]-1-(1-甲基乙基)-2-氧代-3-喹啉甲酰胺
英文名 N-[8-[(2R)-2-hydroxy-3-[methyl(methylsulfonyl)amino]propyl]-8-azabicyclo[3.2.1]octan-3-yl]-2-oxo-1-propan-2-ylquinoline-3-carboxamide
描述 Velusetrag(TD-5108)是5-羟色胺5-HT4受体(5-HT4R)的口服活性、强效和选择性激动剂,pKi为7.7。Velusetrag对5-HT2A和5-HT2B受体没有亲和力(Ki>10μM)。Velusetrag可用于胃肠道疾病和帕金森病的研究[1][2][3][4][5]。

5-HT4 Receptor:7.7 (pKi)

体外研究 Velusetrag(10μM-100μM)浓度依赖性地增加稳定转染h5-HT4(c)受体的HEK-293细胞中的cAMP,pEC50为8.3[1]。Velusetrag(100μM-1μM)产生豚鼠结肠纵肌/肌间神经丛(LMMP)的浓度依赖性收缩,pEC50为7.9[1]。Velusetrag(0.001-10μM)对卡巴胆碱(3μM)预收缩的大鼠食管产生浓度依赖性舒张,pEC50为7.9[1]。
体内研究 Velusetrag(3 mg/kg;单次腹腔注射)显著改善PD小鼠情境恐惧消除的促进作用[3]。Velusetrag(3 mg/kg;单次腹腔注射)可增加1-甲基-4-苯基-1,2,3,6-四氢吡啶(MPTP)治疗小鼠的海马cAMP水平[3]。Velusetrag(0.003-3 mg/kg;单次皮下注射)以剂量依赖性方式增加结肠转运,并减少豚鼠排泄染料所需的时间[2]。Velusetrag(0.003-1 mg/kg;单次静脉注射)剂量依赖性地增加晶体间距离,与大鼠食道松弛一致[2]。动物模型:雄性C57BL/6小鼠(7-8周龄)注射MPTP[3]剂量:3 mg/kg给药:单次腹腔注射。结果:改善了情境恐惧消除的便利性。没有改善PD小鼠受损的rotarod性能。
