HIDE SMILES / InChI
Dihydrocoumarin is a concentrated aromatic and flavor ingredient which may be used in flavor and fragrance compounds according to legal and IFRA or FEMA GRAS/FDA guidelines. Dihydrocoumarin is a common compound found in sweet clover that has been studied as a disruptor of epigenetic processes in cells. Epigenetic processes control gene expression within a cell and are highly influenced by environmental factors. Epigenomic disruptions change which genes are expressed and to what extent and are not linked to DNA mutations. Dihydrocoumarin has been shown to inhibit the sirtuin deacetylase family, specifically Sir2, SIRT1, and SIRT2.
