Prenylflavonoid
Prenylated flavonoids or prenylflavonoids are a sub-class of
Monoprenyl isoflavone epoxidase is a key enzyme in fungal Botrytis cinerea metabolism of prenylated flavonoids.[3]
Many prenylflavonoids appear to have anticancer activity in vitro.[4]
Prenylchalcones, prenylflavones, prenylflavonols and prenylflavanones are classes of prenylflavonoids.
Examples
6-Prenylnaringenin, 6-geranylnaringenin, 8-prenylnaringenin and isoxanthohumol can be found in hops and beer.[5][6] Of the prenylflavonoids, 8-prenylnaringenin is the most potent phytoestrogen known.
Australone A can be found in Morus australis.[7]
6,8-Diprenyleriodictyol, dorsmanin C and dorsmanin F can be found in Dorstenia mannii.[1]
Epimedium wushanense contains a number of flavanoids. 37 compounds were characterized from the underground and aerial parts of the plant. Among them, 28 compounds were prenylflavonoids. The predominant prenylated flavonoid, epimedin C,[8] ranged from 1.4 to 5.1% in aerial parts and 1.0 to 2.8% in underground parts.[9]
Artocarpus nobilis contains prenylated flavonoids in its root bark.[10]
8-Prenylkaempferol can be found in Sophora flavescens.[11]
Cannflavins are prenylflavonoids found in Cannabis sativa.[12]
Prenylated isoflavonoids
A number of bio-active chemicals have been reported from
7-O-Methylluteone is a prenylated isoflavone. It can be found in the bark of Erythrina burttii.
Luteone is another prenylated isoflavone found in the pods of Laburnum anagyroides.
Wighteone (6-prenylgenistein), isowighteone (3′-prenylgenistein), and lupiwighteone (8-prenylgenistein) are genistein prenylated derivatives.[2]
