Description

Kavain, also known as neuronika, 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. kavain is found in Alnus sieboldiana and Piper methysticum. kavain was first documented in 2021 (PMID: 34839465). Based on a literature review a small amount of articles have been published on kavain (PMID: 35278473) (PMID: 35777607) (PMID: 35716919) (PMID: 35703688).
