N,N-Dipropyltryptamine (DPT) is a psychedelic entheogen belonging to the tryptamine family. Use as a designer drug has been documented by law enforcement officials since as early as 1968. However, potential therapeutic use was not investigated until the 1970s. It is found either as a crystalline hydrochloride salt or as an oily or crystalline base. It has not been found to occur endogenously. It is a close structural homologue of dimethyltryptamine and diethyltryptamine.
5-MeO-DMT (5-methoxy-N,N-dimethyltryptamine) or O-methyl-bufotenin is a psychedelic of the tryptamine class. It is found in a wide variety of plant species, and also is secreted by the glands of at least one toad species, the Colorado River toad. Like its close relatives DMT and bufotenin (5-HO-DMT), it has been used as an entheogen in South America. Slang terms include Five-methoxy, The power, and Toad venom.
DET, also known under its chemical name N,N-diethyltryptamine and as T-9, is a psychedelic drug closely related to DMT and 4-HO-DET. However, despite its structural similarity to DMT, its activity is induced by an oral dose of around 50–100 mg, without the aid of MAO inhibitors, and the effects last for about 2–4 hours.
5-MeO-DET or 5-methoxy-N,N-diethyltryptamine is a hallucinogenic tryptamine.
4-HO-MiPT is a synthetic substituted aromatic compound and a lesser-known psychedelic tryptamine. It is thought to be a serotonergic psychedelic, similar to magic mushrooms, LSD and mescaline. Its molecular structure and pharmacological effects somewhat resemble those of the tryptamine psilocin, which is the primary psychoactive chemical in magic mushrooms.
N-Methyl-N-isopropyltryptamine (MiPT) is a psychedelic tryptamine, closely related to DMT, DiPT and Miprocin.
N-Methyltryptamine (NMT) is a member of the substituted tryptamine chemical class and a natural product which is biosynthesized in the human body from tryptamine by certain N-methyltransferase enzymes, such as indolethylamine N-methyltransferase. It is a common component in human urine. NMT is an alkaloid derived from L-tryptophan that has been found in the bark, shoots and leaves of several plant genera, including Virola, Acacia, Mimosa, and Desmanthus—often together with the related compounds N,N-dimethyltryptamine (DMT) and 5-methoxy-N,N-dimethyltryptamine (5-MeO-DMT).
2,N,N-trimethyltryptamine, 2,N,N-TMT, or 2-Me-DMT is a tryptamine derivative that is a psychedelic drug. It was invented by Alexander Shulgin and reported in his book TiHKAL (#34). It is claimed to show psychoactive effects at a dosage of 50–100 mg orally, but these are relatively mild compared to other similar drugs, suggesting that while the 2-methyl group has blocked the binding of metabolic enzymes, it is also interfering with binding to the 5HT2A receptor target that mediates the hallucinogenic effects of these drugs.
N,N-Dibutyltryptamine (DBT) is a psychedelic drug belonging to the tryptamine family. It is found either as its crystalline hydrochloride salt or as an oily or crystalline base. DBT was first synthesized by the chemist Alexander Shulgin and reported in his book TiHKAL . Shulgin did not test DBT himself, but reports a human dosage of "1 mg/kg i.m." being active, but less so than DMT or DET. This suggests that an active dosage of DBT will be in the 100 mg range. This compound has been sold as a "research chemical" and has been confirmed to be an active hallucinogen although somewhat weaker than other similar tryptamine derivatives. It produces a head-twitch response in mice.
MBT, or N-methyl-N-butyltryptamine, is a lesser-known psychedelic drug. MBT was first synthesized by Alexander Shulgin. In his book TiHKAL, the minimum dosage is listed as 250-400 mg, and the duration listed as 4–6 hours. MBT produces a heavy body load with dehydration, and causes visuals similar to those of DMT. Very little data exists about the pharmacological properties, metabolism, and toxicity of MBT.
4-MeO-MiPT, or 4-methoxy-N-methyl-N-isopropyltryptamine, is a lesser-known psychedelic drug. It is the 4-methoxy analog of MiPT. 4-MeO-MiPT was first synthesized by Alexander Shulgin and is mentioned in his book TiHKAL. Subsequent testing by Shulgin on human test subjects showed the effective dose as 20-30 mg ; the onset time between ingestion and the first noticeable effects was 45-60 min, with sensations lasting between 2-2.5 hours. The sensation were significantly milder than those of 4-HO-MiPT, with 4-MeO-MiPT producing erotic-enhancing effects, and few of the visuals common with tryptamines. Very little data exists about the pharmacological properties, metabolism, and toxicity of 4-MeO-MiPT.
5-MeS-DMT (5-methylthio-N,N-dimethyltryptamine) is a lesser-known psychedelic drug. It is the 5-methylthio analog of dimethyltryptamine (DMT). 5-MeS-DMT was first synthesized by Alexander Shulgin. In his book TiHKAL, the minimum dosage is listed as 15-30 mg. The duration listed as very short, just like DMT. 5-MeS-DMT produces similar effects to DMT, but weaker. Shulgin describes his feelings while on a low dose of this drug as "pointlessly stoned", although at a higher dose of 20 mg he says it is "quite intense" and suggests that a higher dose still might have full activity.
5,6-MDO-MiPT, or 5,6-methylenedioxy-N-methyl-N-isopropyltryptamine, is a lesser-known psychedelic drug. It is the 5,6-methylenedioxy analog of MiPT. 5,6-MDO-MiPT was first synthesized by Alexander Shulgin. In his book TiHKAL, 5,6-MDO-MiPT produces slight paresthesia at low doses. Very little data exists about the pharmacological properties, metabolism, and toxicity of 5,6-MDO-MiPT.
5,6-MDO-DiPT, or 5,6-methylenedioxy-N,N-diisopropyltryptamine, is a lesser-known psychedelic drug. It is the 5,6-methylenedioxy analog of DiPT. 5,6-MDO-DiPT was first synthesized by Alexander Shulgin. It is mentioned in his book TiHKAL, but 5,6-MDO-DiPT was never tested to determine what effects it produces, if any. Very little data exists about the pharmacological properties, metabolism, and toxicity of 5,6-MDO-DiPT.
4,5-MDO-DiPT, or 4,5-methylenedioxy-N,N-diisopropyltryptamine, is a lesser-known psychedelic drug. It is the 4,5-methylenedioxy analog of DiPT. 4,5-MDO-DiPT was first synthesized by Alexander Shulgin. In his book TiHKAL, 4,5-MDO-DiPT produces slight LSD-like effects after several hours. Very little data exists about the pharmacological properties, metabolism, and toxicity of 4,5-MDO-DiPT.
4,5-MDO-DMT, or 4,5-methylenedioxy-N,N-dimethyltryptamine, is a lesser-known psychedelic drug. It is the 4,5-methylenedioxy analog of DMT. 4,5-MDO-DMT was first synthesized by Alexander Shulgin, though in his book TiHKAL it was not tested to determine its psychoactive effects. 4,5-MDO-DMT has been the subject of limited subsequent testing; with behavioral disruption studies performed in male rats indicating that its hallucinogenic potency is less than that of 4,5-MDO-DiPT but greater than that of 5,6-MDO-DiPT.
2,α-Dimethyltryptamine (2,α-DMT) is a tryptamine and a lesser-known psychedelic drug. It is the 2,α-dimethyl analog of DMT. Its synthesis was first reported in 1965. Alexander Shulgin lists the dosage as 300-500 mg, and the duration as 7–10 hours in his book TiHKAL. 2,α-DMT causes mydriasis and paresthesia. It also produces a calm, drunk-like feeling. Very little data exists about the pharmacological properties, metabolism, and toxicity of 2,α-DMT.
Alpha,N-DMT, or α,N-dimethyltryptamine, is a lesser-known psychedelic drug. It is the α,N-dimethyl analog of DMT. α,N-DMT was first synthesized by Alexander Shulgin. In his book TiHKAL, Shulgin lists the dosage as 50-100 mg, and the duration as 6–8 hours. α,N-DMT causes an unpleasant body load. Very little data exists about the pharmacological properties, metabolism, and toxicity of α,N-DMT.
O-Acetylbufotenine is a tryptamine derivative which produces psychedelic-appropriate responding in animal studies. It is an acylated derivative of bufotenine with higher lipophilicity that allows it to cross the blood–brain barrier; once inside the brain, it is metabolised to bufotenine. It also acts directly as an agonist at 5-HT1A and 5-HT1D receptors.
5,6-Dibromo-DMT is a substituted tryptamine alkaloid found in some marine sponges. It is briefly mentioned in Alexander Shulgin's book TiHKAL under the DMT entry and is stated to be found, along with other tryptamines, in Smenospongia aurea and other sponges.
