A selective, nonpeptidic, high-affinity nociceptin receptor ORL-1 (ORL1) agonist that elicits anxiolytic-like effects in vivo.
Ro 65-6570 is a nonpeptidic, high-affinity (Ki = 0.52 against 0.1 nM OFQ for binding human ORL1) nociceptin/orphanin FQ (N/OFQ) receptor ORL-1 (KOR-3, NOP) agonist (EC50 = 40 nM by GTPγS binding assay; IC50 = 0.28 nM against 1 μM forskolin-stimulated cellular cAMP accumulation) with good selectivity over opioid receptors μ, k, δ (Ki = 5.9, 26, 250 nM against 1.5 nM naloxone, 3 nM naloxone, 0.3 nM [Ile5,6]-deltorphin II for binding respective receptors), dopamine and serotonin receptors (Ki = 520 nM/D2, 1210 nM/D3,350 nM/D4.4; Ki ≥1 μM for 5HT 1Dα, 2A, 2C, 6, 7). Ro 65-6570 elicits ORL1-dependent anxiolytic-like effects in rats in vivo (0.32-3.2 mg/kg i.p.; elevated plus maze) without affecting spontaneous locomotion. Unlike OFQ, Ro 65-6570 does not affect cocaine-induced conditioned place preference (CPP) in rats.

The discovery of 8-(5,8-dichloro-1,2,3,4-tetrahydro-naphthalen-2-yl)-1-phenyl-1,3,8-triazaspiro[4.5]decan-4-one, 1a, as a high-affinity ligand for the human ORL1 (orphanin FQ/nociceptin) receptor led to the synthesis of a series of optimized ligands. These compounds exhibit high affinity for the human ORL1 receptor, exhibit moderate to good

Nociceptin/orphanin FQ (N/OFQ) receptor (NOP) agonists produce anxiolytic-like effects in rodents while antagonists promote antidepressant-like effects. The aim of this study was to investigate the effect on anxiety and depression of NOP receptor partial agonists such as the peptides [F/G]N/OFQ(1-13)NH2

The aim of the study was to investigate the in vitro and in vivo pharmacological profile of cebranopadol, a novel agonist for opioid and nociceptin/orphanin FQ (N/OFQ) receptors (NOP). In vitro cebranopadol was assayed in calcium mobilization studies in cells coexpressing NOP

Nociceptin/orphanin FQ (N/OFQ) controls several biological functions by selectively activating an opioid like receptor named N/OFQ peptide receptor (NOP). Biased agonism is emerging as an important and therapeutically relevant pharmacological concept in the field of G protein coupled receptors including

The present study investigated the effect of orphanin FQ/nociceptin (OFQ/N), the endogenous ligand of the opioid receptor-like 1 (ORL-1) receptor on the expression of cocaine-induced conditioned place preference (CPP) in rats. To extend this study, the new non-peptidic compound Ro
