J-113,397 is an opioiddrug which was the first compound found to be a highly selective antagonist for the nociceptin receptor, also known as the ORL-1 receptor.[1][2] It is several hundred times selective for the ORL-1 receptor over other opioid receptors,[3][4] and its effects in animals include preventing the development of tolerance to morphine,[5] the prevention of hyperalgesia induced by intracerebroventricular administration of nociceptin (orphanin FQ),[6] as well as the stimulation of dopamine release in the striatum,[7] which increases the rewarding effects of cocaine,[8] but may have clinical application in the treatment of Parkinson's disease.[9][10][11]
