Prenylflavonoids
Prenylated flavonoids or prenylflavonoids are a sub-class of flavonoids. They are widely distributed throughout the plant kingdom. Some are known to have phytoestrogenic or antioxidant properties. They are given in the list of adaptogens in herbalism. Chemically they have a prenyl group attached to their flavonoid backbone. It is usually assumed that the addition of hydrophobic prenyl groups facilitate attachment to cell membranes. Prenylation may increase the potential activity of its original flavonoid. Monoprenyl isoflavone epoxidase is a key enzyme in fungal ''Botrytis cinerea'' metabolism of prenylated flavonoids. Many prenylflavonoids appear to have anticancer activity in vitro. 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. Of the prenylflavonoids, 8-prenylnaringenin is the most potent phyto ...

Cannflavin
Cannflavins are a group of chemical compounds found in ''Cannabis sativa''. 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. Because cannflavins A and B are inhibitors of prostaglandin E2 production ''in vitro'', the cannflavins have been studied for their potential use as anti-inflammatory agents. Biosynthesis Cannflavins A and B are biosynthesized by prenylation of chrysoeriol Chrysoeriol is a flavone, chemically the 3'-methoxy derivative of luteolin. Related compounds Diosmetin is one of three possible regioisomer In chemistry, a structural isomer (or constitutional isomer in the IUPAC nomenclature) of a compo ....

Isoxanthohumol
Isoxanthohumol is a prenylflavonoid, and it is a phytoestrogen. It is abbreviated as IX or IXN. 8-Prenylnaringenin can be produced from isoxanthohumol by flora in the human intestine, and by fungi in cell cultures. This prenylflavonoid is found in hops and beer. It has limited estrogenic activity. At the concentration found in beer, it is unlikely to have an estrogenic effect in breast tissue. Derivatives of isoxanthohumol are: 7,4′-Di-O-methylisoxanthohumol; 7-O-methylisoxanthohumol; 7-O-n-pentylisoxanthohumol; 7,4′-di-O-n-pentyl-8-isoxanthohumol; 7,4′-Di-O-allylisoxanthohumol; 7,4′-Di-O-acetylisoxanthohumol; and 7,4′-Di-O-palmitoylisoxanthohumol. See also * Xanthohumol Xanthohumol is a natural product found in the female inflorescences of '' Humulus lupulus'', also known as hops.

Morus Australis
''Morus australis'', also called Korean mulberry and Chinese mulberry, is a flowering plant species in the genus '' Morus'' found in East and Southeast Asia. The larvae of the freak ('' Calinaga buddha'') feed on ''M. australis''. The substance "Australone A", a prenylflavonoid, can be found in ''M. australis''. Not a true mulberry (i.e. "Plants of the World Online" gives ''M. australis'' as a synonym of the accepted taxonomic designation, ''Broussonetia papyrifera'', the paper mulberry), its fruits and leaves are edible, and it is used as feed in raising silkworms. It is widely used for fibre production, for paper and cloth. Both the ''Broussonetia'' and the ''Morus'' genera are within Moraceae The Moraceae — often called the mulberry family or fig family — are a family of flowering plants comprising about 38 genera and over 1100 species. Most are widespread in tropical and subtropical regions, less so in temperate climates; however ... family. Reference ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Isoflavone
Isoflavones are substituted derivatives of isoflavone, a type of naturally occurring isoflavonoids, many of which act as phytoestrogens in mammals. Isoflavones are produced almost exclusively by the members of the bean family, Fabaceae (Leguminosae). Although isoflavones and closely related phytoestrogens are sold as dietary supplements, there is little scientific evidence for either the safety of long-term supplementation or of health benefits from these compounds. Some studies have identified potential risks from high intake of isoflavones, such as in women with a history of breast cancer, but this concern has not been substantiated with high-quality clinical research. Organic chemistry and biosynthesis Isoflavone is an isomer of flavone, which is chromone substituted with a phenyl group in the 2-position. In isoflavone, the phenyl group is in the 4-position. Isoflavone is of liminted interest per se, but substituted derivatives are of nutritional interest. Substituted deriv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Millettia Pachycarpa
''Millettia pachycarpa'' (synonym ''M. taiwaniana'' Hayata) is a perennial climbing shrub belonging to the genus ''Millettia''. It is one of the most well known among ~150 species of ''Millettia'', as it is widely used in traditional practices, such as for poisoning fish, agricultural pesticide, blood tonic, and treatments of cancer and infertility.
