Amino Acid Sequence

D-Phe-Cys-Tyr-D-Trp-Arg-Thr-Pen-Thr-NH2

Application

CTAP has been used as a μ-opioid receptor (MOR) antagonist:
  • to study the anti-hyperalgesic effect of dipeptidyl peptidase 4 (DPP4) inhibitor isoleucine-proline-isoleucine (IPI) and vildagliptin in carrageenan-induced inflammation
  • to study the role of MOR in glutamate and gamma-aminobutyric acid (GABA) efflux during predator stress in rats
  • to determine the endogenous opioid peptide involved in blocking pain induced by activated gastrin-releasing peptide (Grp+) neurons

Actions biochimiques/physiologiques

CTAP is a peptide antagonist produced from somatostatin analogs.

D-Phe-Cys-Tyr-D-Trp-Arg-Thr-Pen-Thr-NH2 (CTAP) is a cyclic, penicillamine-containing octapeptide that is structurally similar to somatostatin and displays greater antagonist potency and selectivity for mu-opioid receptors, compared with the classical mu-selective antagonist D-Phe-Cys-Tyr-D-Trp-Orn-Thr-Pen-Thr-NH2. The aim of this study was to determine whether CTAP
