| Uses | CTAP acts as a selective μ-opioid receptor antagonist with a multitude of applications including the regulation of aggressive behavior in mammals. Activation of μ-opioid receptors in the central nucleus of the amygdala, is responsible for mechanisms related to the control of sodium appetite and regulation of sodium intake. | | Uses | 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
| | Biochem/physiol Actions | CTAP is a peptide antagonist produced from somatostatin analogs. | | in vivo | CTAP (0-1 mg/kg, IP, single) blocks morphine’s antinociceptive effect[1].
CTAP (10 mg/kg; IP, single) has no effect on L-DOPA-induced limb, axial, orolingual, or locomotor abnormal involuntary movements[1].
CTAP is stable in the blood and serum of rats (T1/2 > 500 min), showing that the structure of this peptide offers enzymatic resistance[2].
CTAP is extensively protein-bound to albumin in the perfusion medium (68.2%) and to proteins in rat serum (84.2%)[2]. | Animal Model: | Male Sprague-Dawley rats[1] | | Dosage: | 0, 0.1, 0.5, 1 mg/kg | | Administration: | IP, single | | Result: | Completely blocked morphine’s antinociceptive effect at 0.5 or 1 mg/kg. |
