Common Name

6-[2-(3,4-dimethoxyphenyl)ethyl]-4-methoxy-5,6-dihydropyran-2-one

Description

11,12-Dimethoxydihydrokawain, also known as 7,8-dihydro-11,12-dimethoxykawain, belongs to the class of organic compounds known as kavalactones. These are lactones, which is structurally characterized by a benzene ring and a pyranone moiety, linked to each other to form a 4-methoxy-6-(2-phenylethyl)-2H-pyran-2-one skeleton. 11,12-Dimethoxydihydrokawain is an extremely weak basic (essentially neutral) compound (based on its pKa). Outside of the human body, 11,12-Dimethoxydihydrokawain has been detected, but not quantified in, beverages. 6-[2-(3,4-dimethoxyphenyl)ethyl]-4-methoxy-5,6-dihydropyran-2-one is found in Aniba hostmanniana and Piper methysticum. This could make 11,12-dimethoxydihydrokawain a potential biomarker for the consumption of these foods.
