一般描述

D-Pen-Cys-Tyr-D-Trp-Orn-Thr-Pen-Thr-NH2(CTOP)是一种选择性的环状μ-阿片受体拮抗剂。

应用

CTOP已用于:
  • 研究CTOP对小鼠和大鼠的抗焦虑作用。
  • 研究μ-阿片受体拮抗剂CTOP对牛乳源性LF(BLF)镇痛作用的影响。
  • 确定μ-阿片受体是否与5-羟色胺(5-HT1A)受体协同作用,以调节在高架T迷宫(ETM)中产生的行为。

生化/生理作用

μ阿片受体的选择性配体。
D-Pen-Cys-Tyr-D-Trp-Orn-Thr-Pen-Thr-NH2(CTOP)在体内以剂量依赖性方式抑制急性吗啡诱导的运动过度和吗啡的镇痛作用。
