Common Name4-[(2e)-but-2-en-2-yl]-6,14-dihydroxy-7,12-dimethyl-2,9-dioxatricyclo[9.4.0.0³,⁸]pentadeca-1(15),3(8),4,6,11,13-hexaen-10-one
DescriptionUnguinol belongs to the class of organic compounds known as depsides and depsidones. These are polycyclic compounds that is either a polyphenolic compound composed of two or more monocyclic aromatic units linked by an ester bond (depside), or a compound containing the depsidone structure (depsidone). Thus, unguinol is considered to be an aromatic polyketide. 4-[(2e)-but-2-en-2-yl]-6,14-dihydroxy-7,12-dimethyl-2,9-dioxatricyclo[9.4.0.0³,⁸]pentadeca-1(15),3(8),4,6,11,13-hexaen-10-one is found in Aspergillus unguis. 4-[(2e)-but-2-en-2-yl]-6,14-dihydroxy-7,12-dimethyl-2,9-dioxatricyclo[9.4.0.0³,⁸]pentadeca-1(15),3(8),4,6,11,13-hexaen-10-one was first documented in 2018 (PMID: 29634062). Based on a literature review a small amount of articles have been published on Unguinol (PMID: 30177651) (PMID: 34208698) (PMID: 33443509) (PMID: 31788435).
