体内活性

Talnetant 在人类重组受体上竞争性拮抗神经激肽B(NKB)诱导的反应，展现于钙离子和磷酸肌醇二级信使测定系统中(pA2分别为8.1和7.7)。在豚鼠脑切片中，talnetant拮抗了NKB在内侧缰核诱导的神经元放电增加(pKB=7.9)，以及senktide在黑质紧凑部诱导的神经元放电增加(pKB=7.7)，且未减少最大激动剂的效能，提示其在NK3受体上表现出竞争性拮抗作用。Talnetant(3-30 mg/kg, i.p.)在豚鼠中以剂量依赖性方式显著减轻了senktide诱导的“湿狗抖动”行为。微透析研究显示，talnetant的急性给药(30 mg/kg, i.p.)在自由移动的豚鼠中显著增加了内侧前额叶皮层中的外细胞多巴胺和去甲肾上腺素水平，并减轻了氟哌啉醇诱导的伏隔核多巴胺水平增加。
