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.^[1][2]

Norbaeocystin is generally thought to be non-psychoactive, although this has not been confirmed.^[3]

Norbaeocystin (4-PO-T) is thought to be a prodrug of 4-hydroxytryptamine (4-HT), analogously to how psilocybin (4-PO-DMT) is a prodrug of psilocin (4-HO-DMT) and baeocystin (4-PO-NMT) is thought to be a prodrug of norpsilocin (4-HO-NMT).^[4][5] 4-HT is a potent and centrally penetrant serotonin 5-HT_2A receptor agonist and also interacts with other serotonin receptors.^[4] In spite of this however, 4-HT and norbaeocystin do not produce the head-twitch response, a behavioral proxy of psychedelic effects, in animals, and hence are putatively non-hallucinogenic.^[4][5] The reasons for this are unknown, but may be due to β-arrestin2-preferring biased agonism of the serotonin 5-HT_2A receptor.^[4]

Norbaeocystin is an N–demethylated derivative of baeocystin (itself an N-demethylated derivative of psilocybin), and a phosphorylated derivative of 4-hydroxytryptamine (4-HT).^{[citation needed]} The latter is notable as a positional isomer of serotonin, which is 5-hydroxytryptamine (5-HT).^{[citation needed]}

Derivatives of norbaeocystin (4-PO-T), also known as substituted 4-phosphoryloxytryptamines, include baeocystin (4-PO-NMT), psilocybin (4-PO-DMT), ethocybin (4-PO-DET), 4-PO-DiPT, 4-PO-MET, and aeruginascin (4-PO-TMT), among others.

Norbaeocystin was found to be sold as an analytical standard in 2023.^[3]
