Common Name

8a-methyl-3,5-dimethylidene-3ah,4h,4ah,9h,9ah-naphtho[2,3-b]furan-2,6-dione

Description

Encelin, also known as dehydro-farinosin, belongs to the class of organic compounds known as eudesmanolides, secoeudesmanolides, and derivatives. These are terpenoids with a structure based on the eudesmanolide (a 3,5a,9-trimethyl-naphtho[1,2-b]furan-2-one derivative) or secoeudesmanolide (a 3,6-dimethyl-5-(pentan-2-yl)-1-benzofuran-2-one derivative) skeleton. Encelin is an extremely weak basic (essentially neutral) compound (based on its pKa). Outside of the human body, Encelin has been detected, but not quantified in, herbs and spices. 8a-methyl-3,5-dimethylidene-3ah,4h,4ah,9h,9ah-naphtho[2,3-b]furan-2,6-dione is found in Encelia asperifolia, Montanoa speciosa and Saussurea parviflora. 8a-methyl-3,5-dimethylidene-3ah,4h,4ah,9h,9ah-naphtho[2,3-b]furan-2,6-dione was first documented in 2003 (PMID: 12648535). This could make encelin a potential biomarker for the consumption of these foods.

Chemical Taxonomy

Description

Belongs to the class of organic compounds known as eudesmanolides, secoeudesmanolides, and derivatives. These are terpenoids with a structure based on the eudesmanolide (a 3,5a,9-trimethyl-naphtho[1,2-b]furan-2-one derivative) or secoeudesmanolide (a 3,6-dimethyl-5-(pentan-2-yl)-1-benzofuran-2-one derivative) skeleton.
