BW-501C67 is a peripherally selective serotonin 5-HT2A and 5-HT2C receptor antagonist which is used in scientific research.[1][2][3][4][5][6] It shows selectivity for the serotonin 5-HT2 receptors over the α1-adrenergic receptor.[1]

The drug antagonizes peripheral but not central effects of serotonin receptor agonists like serotonin.[2][3][7][6] As examples, it has been found to antagonize the sympathomimetic effects of serotonin in animals, including vasoconstriction and pressor effects, but does not block centrally mediated effects like increased corticosterone secretion or myoclonus.[3][7][8][6]

BW-501C67 and analogues were patented for use in combination with serotonin 5-HT2A receptor agonists like serotonergic psychedelics in 2023.[9]
