BW-501C67 is a peripherally selective serotonin 5-HT_2A and 5-HT_2C 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-HT_2A receptor agonists like serotonergic psychedelics in 2023.^[9]
