Amino Acid Sequence

Phe-Cys-Tyr-Trp-Orn-Thr-Pen-Thr-NH2 [Disulfide Bridge: 2-7]

Description générale

D-Pen-Cys-Tyr-D-Trp-Orn-Thr-Pen-Thr-NH2 (CTOP) is a selective cyclic μ-opioid receptor antagonist.

Application

CTOP has been used:
  • to study the anxiogenic effects induced by CTOP in mice and rat.
  • to study the effect of μ-opioid antagonist, CTOP on the bovine milk-derived LF (BLF)-induced analgesia.
  • to determine whether μ-opioid receptors act cooperatively with 5-hydroxytryptamine (5-HT1A) receptors to regulate the behaviors generated in the elevated T-maze (ETM).

Actions biochimiques/physiologiques

D-Pen-Cys-Tyr-D-Trp-Orn-Thr-Pen-Thr-NH2 (CTOP) inhibits acute morphine-induced hypermotility and analgesic effect of morphine in a dose-dependent manner in vivo.
Selective ligand for μ-opioid receptors.

Liaison
