GR-127935 is a drug which acts as a selective antagonist at the serotonin receptors 5-HT1B and 5-HT1D.[1] It has little effect when given by itself but blocks the antiaggressive effect of 5-HT1B agonists,[2] and alters release of serotonin in the brain,[3] as well as reducing drug-seeking behaviour in cocaine addicted rats.[4]
