amphicordin A

Description

Amphicordin A belongs to the class of organic compounds known as pyranochromenes. These are organic heterocyclic compounds containing a pyran ring fused to a chromene (1-benzopyran) moiety. amphicordin A was first documented in 2023 (PMID: 37967166). Based on a literature review very few articles have been published on amphicordin A.
