5-Bromo-DMT (5-bromo-N,N-dimethyltryptamine) is a psychedelic brominated indole alkaloid found in the sponges Smenospongia aurea and Smenospongia echina , as well as in Verongula rigida (0.00142% dry weight) alongside 5,6-Dibromo-DMT (0.35% dry weight) and seven other alkaloids. [1] [2] [3] [4] It is the 5-bromo derivative of DMT, a psychedelic found in many plants and animals.


5-Bromo-DMT has a pEC50 value of 5.51 for the 5-HT2A receptor. [5]

Animal studies on 5-Bromo-DMT showed that it produces effects suggestive of sedative and antidepressant activity and caused significant reduction of locomotor activity in the rodent FST model. [6]

5-Bromo-DMT was reported to be psychoactive at 20–50 mg via vaporization with mild psychedelic-like activity. [7]


5-Bromo-DMT is specifically listed as a controlled drug in Singapore. [8]

<i>N</i>,<i>N</i>-Dimethyltryptamine Chemical compound

N,N-Dimethyltryptamine is a substituted tryptamine that occurs in many plants and animals and which is both a derivative and a structural analog of tryptamine. It is used as a recreational psychedelic drug and prepared by various cultures for ritual purposes as an entheogen.

Psychedelic drug Hallucinogenic class of psychoactive drug

Psychedelics are a class of hallucinogenic drugs whose primary effect is to trigger non-ordinary states of consciousness via serotonin 2A receptor agonism. This causes specific psychological, visual and auditory changes, and often a substantially altered state of consciousness. The "classical" psychedelics, the psychedelics with the largest scientific and cultural influence, are mescaline, LSD, psilocybin, and DMT.

Psilocin psychedelic substance

Psilocin is a substituted tryptamine alkaloid and a serotonergic psychedelic substance. It is present in most psychedelic mushrooms together with its phosphorylated counterpart psilocybin. Psilocin is a Schedule I drug under the Convention on Psychotropic Substances. The mind-altering effects of psilocin are highly variable, subjective and resemble those of LSD and DMT.


Methylergometrine, also known as methylergonovine and sold under the brand name Methergine, is a medication of the ergoline and lysergamide groups which is used as an oxytocic in obstetrics and in the treatment of migraine. It reportedly produces psychedelic effects similar to those of lysergic acid diethylamide (LSD) at high doses.


2C-B-FLY is a psychedelic phenethylamine of the 2C family. It was first synthesized in 1996 by Aaron P. Monte.

Indole alkaloid

Indole alkaloids are a class of alkaloids containing a structural moiety of indole; many indole alkaloids also include isoprene groups and are thus called terpene indole or secologanin tryptamine alkaloids. Containing more than 4100 known different compounds, it is one of the largest classes of alkaloids. Many of them possess significant physiological activity and some of them are used in medicine. The amino acid tryptophan is the biochemical precursor of indole alkaloids.


5-Fluoro-α-methyltryptamine (5-Fluoro-αMT), also known as PAL-544, is a putative stimulant, entactogen, and psychedelic tryptamine derivative related to α-methyltryptamine (αMT). It has been found to act as a well-balanced serotonin-norepinephrine-dopamine releasing agent, a 5-HT2A receptor agonist, and a potent and specific MAO-A inhibitor. It produces a strong head-twitch response in mice, and this effect is known to correlate with psychedelic effects in humans, which suggests that 5-fluoro-αMT could be an active psychedelic in humans, although it is not known to have been tested in humans and could be dangerous due to its strong inhibition of MAO-A.


AL-34662 is an indazole derivative drug that is being developed for the treatment of glaucoma. It acts as a selective 5-HT2A receptor agonist, the same target as that of psychedelic drugs like psilocin, but unlike these drugs, AL-34662 was designed specifically as a peripherally selective drug, which does not cross the blood–brain barrier. This means that AL-34662 can exploit a useful side effect of the hallucinogenic 5-HT2A agonists, namely reduction in intra-ocular pressure and hence relief from the symptoms of glaucoma, but without causing the hallucinogenic effects that make centrally active 5-HT2A agonists unsuitable for clinical use. In animal studies, AL-34662 has been shown to be potent and effective in the treatment of symptoms of glaucoma, with minimal side effects.


5-Fluoro-N,N-dimethyltryptamine (5-fluoro-DMT) is a tryptamine derivative related to compounds such as 5-bromo-DMT and 5-MeO-DMT. Fluorination of psychedelic tryptamines either reduces or has little effect on 5-HT2A/C receptor affinity or intrinsic activity, although 6-fluoro-DET is inactive as a psychedelic despite acting as a 5-HT2A agonist, while 4-fluoro-5-methoxy-DMT is a much stronger agonist at 5-HT1A than 5-HT2A.


Dimemebfe (5-MeO-BFE) is a recreational drug and research chemical. It acts as an agonist for the 5-HT1A and 5-HT2 family of serotonin receptors. It is related in structure to the psychedelic tryptamine derivative 5-MeO-DMT, but with the indole nitrogen replaced by oxygen, making dimemebfe a benzofuran derivative. It is several times less potent as a serotonin agonist than 5-MeO-DMT and with relatively more activity at 5-HT1A, but still shows strongest effects at the 5-HT2 family of receptors.


6-Fluoro-N,N-dimethyltryptamine (6-Fluoro-DMT) is a synthetic drug of the tryptamine chemical class.


5-Methoxy-7,N,N-trimethyltryptamine (5-MeO-7,N,N-TMT, 5-MeO-7-TMT), is a tryptamine derivative which acts as an agonist at the 5-HT2 serotonin receptors. In animal tests, both 7,N,N-TMT and 5-MeO-7,N,N-TMT produced behavioural responses similar to those of psychedelic drugs such as DMT and 5-MeO-DMT, but compounds with larger 7-position substituents such as 7-ethyl-DMT and 7-bromo-DMT did not produce psychedelic-appropriate responding despite high 5-HT2 receptor binding affinity, suggesting these may be antagonists or weak partial agonists for the 5-HT2 receptors. The related compound 7-MeO-MiPT (cf. 5-MeO-MiPT) was also found to be inactive, suggesting that the 7-position has poor tolerance for bulky groups at this position, at least if agonist activity is desired.


7,N,N-Trimethyltryptamine (7-methyl-DMT, 7-TMT), is a tryptamine derivative which acts as an agonist of 5-HT2 receptors. In animal tests, both 7-TMT and its 5-methoxy derivative 5-MeO-7-TMT produced behavioural responses similar to those of psychedelic drugs such as DMT, but the larger 7-ethyl and 7-bromo derivatives of DMT did not produce psychedelic responses despite having higher 5-HT2 receptor affinity in vitro (cf. DOBU, DOAM). 7-TMT also weakly inhibits reuptake of serotonin but with little effect on dopamine or noradrenaline reuptake.

<i>N</i>-Methylserotonin Chemical compound

N-Methylserotonin is a tryptamine alkaloid. Chemically, it is a derivative of serotonin in which a methyl group resides at its alkyl amine. It is also called Nω-methylserotonin (Nω-methyl-5-hydroxytryptamine) to distinguish it from tryptamine-derived compounds in which a methyl group is bonded to the nitrogen atom of the indole group.


CP-132,484 is a tryptamine derivative which acts as a potent and selective agonist for the 5-HT2 family of serotonin receptors. It has reasonable selectivity for 5-HT2A and 5-HT2C subtypes over 5-HT2B, but is only slightly selective for 5-HT2A over 5-HT2C. This compound and several related analogues have been shown to have ocular hypotensive activity in animal models, suggesting they may be useful for the treatment of glaucoma.


5-Chloro-α-methyltryptamine (5-Chloro-αMT), also known as PAL-542, is a tryptamine derivative related to α-methyltryptamine (αMT) and one of only a few known specific serotonin-dopamine releasing agents (SDRAs). It has been investigated in animals as a potential treatment for cocaine dependence. The EC50 values of 5-chloro-αMT in evoking the in vitro release of serotonin (5-HT), dopamine (DA), and norepinephrine (NE) in rat synaptosomes were reported as 16 nM, 54 nM, and 3434 nM, with an NE/DA ratio of 63.6 and a DA/5-HT ratio of 3.38, indicating that it is a highly specific and well-balanced SDRA. However, 5-chloro-αMT has also been found to act as a potent full agonist of the 5-HT2A receptor, with an EC50 value of 6.27 nM and an efficacy of 105%, and almost assuredly acts as a potent agonist of other serotonin receptors as well.

Barettin Chemical compound

Barettin is a brominated alkaloid made of a dehydrogenated brominated derivative of tryptophan linked by two peptide bonds to an arginine residue, forming a 2,5-diketopiperazine nucleus. It is a cyclic dipeptide.

Smenospongia echina is a species of sea sponge in the class Demospongiae. The scientific name of the species was first validly published in 1934 by Max Walker de Laubenfels, as Polyfibrospongia echina.


AAZ-A-154 is an isotryptamine derivative which acts as a 5-HT2A receptor agonist. Animal studies suggest that it produces antidepressant effects without the psychedelic action typical of drugs from this class.
