Trimethoxyamphetamine Trimethoxyamphetamine TMAs, also known as trimethoxyamphetamines, are a family of isomeric psychedelic hallucinogenic drugs. There exist six different TMAs that differ only in the position of the three methoxy groups: TMA, TMA-2, TMA-3, TMA-4, TMA-5, and TMA-6. The TMAs are analogs of the phenethylamine cactus alkaloid mescaline. The TMAs are substituted amphetamines, however, their action does not resemble that of the unsubstituted compound "amphetamine", which is a stimulant and not a psychedelic. It is reported that some TMA's elicit a range of emotions ranging from sadness to empathy and euphoria. TMA was first synthesized by Hey, in 1947. Synthesis data
Isoproscaline mechanism of action shared by all of the hallucinogenic tryptamines and phenethylamines. The toxicity of isoproscaline is not known. Isoproscaline is unscheduled and unregulated in the United States, however because of its close similarity in structure and effects to mescaline, possession and sale of isoproscaline may be subject to prosecution under the Federal Analog Act. In the UK its highly likely that this compound would be covered by the "phenylethylamine amendment" to the misuse of drugs act likely rendering it (probably) a Class A controlled drug. Isoproscaline Isoproscaline or 4-(i)-propoxy-3,5-dimethoxyphenethylamine is an analogue of mescaline. It is closely related to
