Insights into Ganoderma fungi meroterpenoids opening a new era of racemic natural products in mushrooms

Abstract

AbstractGanoderma meroterpenoids (GMs) containing 688 structures to date were discovered to have multiple remarkable biological activities. 65.6% of meroterpenoids featuring stereogenic centers from Ganoderma species are racemates. Further, GMs from different Ganoderma species seem to have their own characteristics. In this review, a comprehensive summarization of GMs since 2000 is presented, including GM structures, structure corrections, biological activities, physicochemical properties, total synthesis, and proposed biosynthetic pathways. Additionally, we especially discuss the racemic nature, species‐related structural distribution, and structure–activity relationship of GMs, which will provide a likely in‐house database and shed light on future studies on GMs.
