What is Ergosterol peroxide?

Plain description, key identifiers and synonyms

Ergosterol peroxide is an ergostanoid that is ergosta-6,22-dien-3-ol with a peroxy group between positions 5 and 8 (the 3beta,5alpha,8alpha,22E stereoisomer). Isolated from Ganoderma lucidum and Cordyceps sinensis, it exhibits antimycobacterial, trypanocidal and antineoplastic activities. It has a role as a metabolite, an antineoplastic agent, a trypanocidal drug and an antimycobacterial drug. It is an organic peroxide, a member of phytosterols, a 3beta-sterol and an ergostanoid. It is functionally related to an ergosterol.
