4-Phosphoryloxytryptamines

Psilocybin, also known as '4-phosphoryloxy-N,N-dimethyltryptamine (4-PO-DMT'), is a naturally occurring tryptamine alkaloid and investigational drug found in more than 200 species of mushrooms, with hallucinogenic and serotonergic effects. Effects include euphoria, changes in perception, a distorted sense of time, and perceived spiritual experiences. It can also cause adverse reactions such as nausea and panic attacks.

Baeocystin, also known as norpsilocybin or '4-phosphoryloxy-N-methyltryptamine (4-PO-NMT'), is a zwitterionic alkaloid of the tryptamine family and an analogue of psilocybin (4-PO-DMT). It is found as a minor compound in most psilocybin mushrooms together with psilocybin, psilocin (4-HO-DMT), norbaeocystin (4-PO-T), and aeruginascin (4-PO-TMT). The compound is the N-demethylated derivative of psilocybin and the 4-phosphorylated derivative of norpsilocin (4-HO-NMT).

Norbaeocystin, also known as 4-phosphoryloxytryptamine (4-PO-T), is a psilocybin mushroom alkaloid of the tryptamine family and an analogue of psilocybin (4-PO-DMT). It is found as a minor compound in most psilocybin mushrooms, together with psilocybin, psilocin (4-HO-DMT), aeruginascin (4-PO-TMT), and baeocystin (4-PO-NMT), from which it is a derivative.

Ethocybin also known as '4-phosphoryloxy-N,N-diethyltryptamine (4-PO-DET) or as CEY-19', is a psychedelic drug of the tryptamine and 4-hydroxytryptamine families related to the psilocybin-containing mushroom alkaloid psilocybin. It is assumed to act as a prodrug of 4-HO-DET (CZ-74) analogously to how psilocybin (4-PO-DMT) acts as a prodrug of psilocin (4-HO-DMT). The drug was first described in the literature by Albert Hofmann and colleagues at Sandoz by 1963.

Aeruginascin, also known as '4-phosphoryloxy-N,N,N-trimethyltryptamine (4-PO-TMT'), is an indoleamine derivative which occurs naturally within the mushrooms Inocybe aeruginascens, Pholiotina cyanopus, and Psilocybe cubensis. It was discovered by Jochen Gartz.
