Selective and competitive nociceptin receptor antagonist, devoid of any agonist activity. Binds selectively to recombinant nociceptin receptors (pKi = 8.4), and competitively antagonizes the actions of nociceptin in vitro and in vivo.
Potent agonist of the nociceptin (ORL1) receptor, demonstrated both in vitro and in vivo. Selective, competitive antagonism at the nociceptin receptor has also been reported (pA2 = 7.02 and 6.75 in the guinea pig ileum and mouse vas deferens respectively)
Highly potent and selective NOP receptor agonist (EC50 = 1 nM). Displays > 875-fold selectivity over opioid receptors (IC50 values are 0.32, 280, > 10000 and 1500 for NOP, μ, δ and κ receptors respectively). Longer lasting and 30-fold more potent than noc
MT-7716 free base is a selective non-peptide agonist of nociceptin receptor (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 nociceptin receptor 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
