CP-122,288 is a drug which acts as a potent and selective agonist for the 5-HT_1B, 5-HT_1D and 5-HT_1F serotonin receptor subtypes. It is a derivative of the migraine medication sumatriptan, but while CP-122,288 is 40,000 times more potent than sumatriptan as an inhibitor of neurogenic inflammation and plasma protein extravasation, it is only twice as potent as a constrictor of blood vessels. In human trials, CP-122,288 was not found to be effective as a treatment for migraine, but its selectivity for neurogenic anti-inflammatory action over vasoconstriction has made it useful for research into the underlying causes of migraine.^{[1][2][3][4][5]}
