MT-7716 free base is a selective non-peptide agonist of nociceptinreceptor (NOP). It is used for promising potential treatment drugs for alcohol abuse and relapse prevention.
Ro 64-6198 is a nonpeptide, high-affinity, and brain penetration N OFQ receptor (NOP) agonist (EC50: 25.6 nM). Ro 64-6198 is at least 100 times more selective for the NOP receptor over the classic opioid receptors.
MCOPPB is a potent and selective agonist for the nociceptinreceptor with a pKi of 10.07, much weaker activity at other opioid receptors. In animal studies, MCOPPB produces potent anxiolytic effects, with no inhibition of motor or memory function, and onl
AT-076 is a noncompetitive antagonist of the κ-opioid receptor (Ki = 1.14 nM) and nociceptinreceptor (Ki = 1.75 nM) and a competitive antagonist of the μ-opioid receptor (Ki = 1.67 nM) and δ-opioid receptor (Ki = 19.6 nM).
SB-612111 is a novel and potent human opiate receptor-like orphan receptor (ORL-1) antagonist with a high affinity for hORL-1 (Ki=0.33 nM). SB-612111 exhibits selectivity for μ-, κ- and δ-receptors with Ki values of 57.6 nM, 160.5 nM and 2109 nM, respecticely. SB-612111 effectively antagonizes the pronociceptive action of Nociceptin in an acute pain model[1]. [1]. Paola F Zaratin, et al.

Ac-RYYRWK-NH2 is a highly effective and specific partial agonist for the nociceptinreceptor (NOP). It demonstrates a remarkable affinity for rat cortical membranes ORL1, with [3H]Ac-RYYRWK-NH2 exhibiting a Kd value of 0.071 nM. However, it shows negligible affinity towards μ-, κ-, or δ-opioid receptors.
