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
4,5-Dihydroxy-2,3-pentanedione 4,5-Dihydroxy-2,3-pentanedione 4,5-Dihydroxy-2,3-pentanedione (DPD) is an organic compound that occurs naturally but exists as several related structures. The idealized formula for this species is CHC(O)C(O)CH(OH)CHOH, but it is known to exist as several other forms resulting from cyclization. It is not stable at room temperature as a pure material, which has further complicated its analysis. The ("S")-stereoisomer occurs naturally. It is typically hydrated, i.e., one keto group has added water to give the geminal diol. DPD is produced by degradation of "S"-adenosylhomocysteine by the action of the enzyme "S"-ribosylhomocysteinase. The compound probably does not exist as depicted above, but as an
