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。

Aim: To examine the effects of fentanyl, a potent mu-opioid receptor (MOR) agonist, on-air puff-evoked responses in Purkinje cells (PCs), and molecular layer interneurons (MLIs) using in vivo patch-clamp recordings in anesthetized mice. Methods: Male mice 6-8 weeks-old were anesthetized

Although the classical function of myelin is the facilitation of saltatory conduction, this membrane and the oligodendrocytes, the cells that make myelin in the central nervous system (CNS), are now recognized as important regulators of plasticity and remodeling in the

The decision to perform, or not perform, actions known to lead to a rewarding outcome is strongly influenced by the current incentive value of the reward. Incentive value is largely determined by the affective experience derived during previous consumption of

In addition to analgesia, opioids may also produce paradoxical pain amplification [opioid-induced hyperalgesia (OIH)] either on abrupt withdrawal or during continuous long-term application. Here, we assessed antinociceptive and pronociceptive effects of three clinically used opioids at C-fiber synapses in the
