Bufotenidine Bufotenidine, also known as 5-hydroxy-"N","N","N"-trimethyltryptammonium (5-HTQ), is a toxin related to bufotenin, serotonin, and other tryptamines which is found in the venom of a variety of toads. It acts as a selective 5-HT receptor agonist, and has been used in scientific research to study the function of the 5-HT receptor, though this use has been limited by the fact that, as a quaternary amine, it is unable to readily cross the blood-brain-barrier.
