Cannflavin

Cannflavins are a group of chemical compounds found in Cannabis sativa.^[1] Chemically, they are prenylflavonoids and are unrelated to THC and other cannabinoids. Cannflavins A and B were first identified in the 1980s and cannflavin C was identified in 2008.^[2]

Because cannflavins A and B are inhibitors of prostaglandin E2 production in vitro,^[1][3] the cannflavins have been studied for their potential use as anti-inflammatory agents.^[4]

Biosynthesis

Cannflavins A and B are biosynthesized by prenylation of chrysoeriol.^[5]
