5-Bromo-DMT, scientifically known as 5-Bromo-N, N-dimethyltryptamine, is a psychedelic compound in the class of brominated indole alkaloids. This particular alkaloid can be found in sponges like Smenospongia aurea and Smenospongia echina, as well as in Verongula rigida, where it constitutes a minute fraction of the dry weight (approximately 0.00142%). It is found alongside 5,6-Dibromo-DMT (at about 0.35% dry weight) and seven other alkaloids in Verongula rigida. Notably, 5-Bromo-DMT is the 5-bromo derivative of DMT, another well-known psychedelic compound in various plants and animals.
Regarding its pharmacological properties, 5-Bromo-DMT exhibits a pEC50 value of 5.51 for the 5-HT2A receptor.
Animal studies conducted on 5-Bromo-DMT suggest that it may produce effects indicative of sedative and antidepressant activity. Additionally, it was observed to cause a significant reduction in locomotor activity in a rodent model called the FST (Forced Swim Test).
Reportedly, 5-Bromo-DMT can be psychoactive when vaporized at 20 to 50 mg doses, resulting in mild psychedelic-like experiences.
