5-Bromo-DMT (5-bromo-N,N-dimethyltryptamine) is a brominated indole alkaloid found in certain marine invertebrates. It is the 5-bromo analogue of DMT, a psychedelic found in many plants and animals.[1] Other naturally occurring 5-substituted analogues of DMT include bufotenin and 5-MeO-DMT, both of which, like DMT, are psychoactive and found in plants and animals. Animal studies on 5-bromo-DMT showed it to produce effects suggestive of sedative and antidepressant activity.[2]

Anecdotal reports published by Hamilton Morris indicate that 5-Bromo-DMT freebase is psychoactive in humans when smoked at doses between 20 and 50 milligrams.[3]

This compound is soluble in ethanol and methanol. It has been found in Verongula rigida (0.00142% dry wt.) along with 5,6-diBr-DMT (0.35% dry wt.) and seven other alkaloids. 5-Br-DMT caused significant reduction of locomotor activity in the rodent FST model (suggested to indicate a potential sedative action). It did not show any antidepressant activity in either test. [4]
