AMDA (9-Aminomethyl-9,10-dihydroanthracene) is an organic compound which acts as a potent and selective antagonist for the 5-HT2A receptor.[1] It has been used to help study the shape of the 5-HT2A protein,[2] and develop a large family of related derivatives with even higher potency and selectivity.[3][4][5][6][7]
