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.
Use and effects
Norbaeocystin is generally thought to be non-psychoactive, although this has not been confirmed.
Pharmacology
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-HT is a potent and centrally penetrant serotonin 5-HT<sub>2A</sub> receptor agonist and also interacts with other serotonin receptors.
