Turmerone

Turmerones are a group of related chemical compounds of the sesquiterpene class. They are found in turmeric (Curcuma longa),^[1] from which they derive their name, as well as other related plants such as Curcuma caesia.^[2] There are multiple structural types of turmerones which differ in the number and placement of double bonds including α-tumerone, β-turmerone (also known as curlone), and ar-turmerone. Each of these types consists of multiple stereoisomers.

A number of in vitro biological activities of turmerones have been reported, including antiinflammatory, immunomodulatory, antiproliferative, and antifungal activities.^[3][4][5]
