斯佩西亭（英語：Speciociliatine）^[2]是存在于卡痛树中主要生物碱，其为哥冬树中的另一种主要生物碱帽柱碱（英语：Mitragynine）的立体异构体。在干叶片中含量为0.00156- 2.9%。^[3]^[4]为一种阿片样肽受体配体。

药理作用

已知斯佩西亭是μ-阿片样肽受体（英语：μ-opioid receptor）和κ-阿片样肽受体（英语：κ-opioid receptor）的配体，但其起到激动剂还是竞争拮抗剂作用目前存在争议。^[5]^[6]

在雄性实验大鼠身上测试表明，口服20 mg/kg斯佩西亭后，斯佩西亭的消除半衰期为2.6 - 5小时，绝对生物利用度为20.7%^[7]。
