Opposite effects of intraventricular and intracisternal administration of vasopressin on blood pressure in rats.

abstract：:The heptadecapeptide, orphanin FQ or nociceptin (Phe-Gly-Phe-Thr-Gly-Ala-Arg-Lys-Ser-Ala-Arg-Lys-Leu-Ala-Asn-Gln), originally isolated from rat brain has been identified as an endogenous ligand for the orphan opioid-like receptor. Although orphanin FQ shares some sequence and structural homology with kappa-opioid pept...

abstract：:Recent studies have identified compounds with reduced efficacy relative to nociceptin/orphanin FQ at the opioid-like receptor ORL1. Utilizing stimulation of [(35)S]GTPgammaS binding as in vitro assays, it was determined that both [Phe(1)psi(CH(2)-NH)Gly(2)]N/OFQ(1-13)NH(2) and the hexapeptide Ac-RYYRIK-NH(2) act as pa...
