| Description | Helicusin E belongs to the class of organic compounds known as azaphilones. These are a structurally variable family of fungal polyketide metabolites possessing a highly oxygenated pyranoquinone bicyclic core, usually known as isochromene, and a quaternary carbon center. Helicusin E is found in Bartalinia and Bartalinia robillardoides. Helicusin E was first documented in 2013 (PMID: 23481677). Based on a literature review very few articles have been published on Helicusin E. |
