SB 242084 hydrochloride is a potent and selective antagonist of the SR-2C (5-HT2C receptor) (pKi = 9.0), with at least 100-fold more selectivity over other serotonin, dopamine or adrenergic receptors. In vivo, it is a brain penetrant and has significant anxiolytic activity, without sedative, proconvulsant, or hyperphagic properties. It increases the basal activity of dopaminergic neurons and affects the behavioral responses mediated by 5-HT2C such as mesolimbic neuron activity and food intake. SB 242084 hydrochloride has been used extensively in animal research to evaluate SR-2C agonists and neurotransmitter receptor interactions in mice.
