MCOPPB Inhibitor

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 only slight sedative side effects.

Small volumes of MCOPPB, inhibitor vial(s) may occasionally become entrapped in the seal of the product vial during shipment and storage. If necessary, briefly centrifuge the vial on a tabletop centrifuge to dislodge any liquid in the container`s cap. Certain products may require to ship with dry ice and additional dry ice fee may apply.
