Summary
Psilocybin, a potent alkaloid and hallucinogen found in certain mushrooms, exhibits unique chemistry causing psychotomimetic effects like hallucinations and nerve excitation. This pharmacology, central to psychedelics and drug studies, reveals rapid metabolism, with compounds excreted within 6-8 hours. Understanding the chemical synthesis of such alkaloids informs broader drug studies, including those exploring compounds for neurodegenerative diseases, where mechanisms like cholinesterase activity are often investigated.
Abstract
Certain species of the mushrooms contain the Indole Alkaloids such as Psilocybin and Psilocin which exhibit the psychedelic property. These types of mushrooms can be identified by their unique property known as the blue bruising. These alkaloid compounds may cause the hallucinations and other symptoms. The psilocybin and Psilocin are synthesized from the amino acid Tryptophan and resemble the structure of the hormone Serotonin. They also act as an agonist for the 5-HT2A receptors. Intoxication of these compounds can lead to excitation of the nerves which can eventually cause the hallucination, tachycardia, dilated pupils and dysuria in certain cases which may lead to adverse effects. The metabolic product of the Psilocin is psilocin-o-glucuronide which is excreted in the urine within 6-8 hours of ingestion. Psilocybin and psilocin can be analyzed by preliminary color tests with Ehrlich reagent, Marquis reagentand Mandelin’s reagent. In this review, brief reports are presented about the chromatographic analysis of these compounds. This articlealso discusses the overview of the psychoactive alkaloids present in certain species of mushrooms
