Luteone (isoflavone)
Luteone is a prenylated 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) ..., a type of flavonoid. It can be found in the pods of '' Laburnum anagyroides'' and can be synthesized. References Isoflavones Prenylflavonoids Resorcinols {{aromatic-stub ...

Prenyl
Prenylation (also known as isoprenylation or lipidation) is the addition of hydrophobic molecules to a protein or a biomolecule. It is usually assumed that prenyl groups (3-methylbut-2-en-1-yl) facilitate attachment to cell membranes, similar to lipid anchors like the GPI anchor, though direct evidence of this has not been observed. Prenyl groups (also called isoprenyl groups, having one hydrogen atom more than isoprene) have been shown to be important for protein–protein binding through specialized prenyl-binding domains. Protein prenylation Protein prenylation involves the transfer of either a farnesyl or a geranylgeranyl moiety to C-terminal cysteine(s) of the target protein. There are three enzymes that carry out prenylation in the cell, farnesyl transferase, Caax protease and geranylgeranyl transferase I. Farnesylation is a type of prenylation, a post-translational modification of proteins by which an isoprenyl group is added to a cysteine residue. It is an important ...

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] |
Laburnum Anagyroides
''Laburnum anagyroides'' ( syn. ''Cytisus laburnum''), the common laburnum, golden chain or golden rain, is a species of flowering plant in the subfamily Faboideae, and genus ''Laburnum''. '' Laburnum alpinum'' is closely related. It is native to Central and Southern Europe. The plant grows and flowers in damp and mild habitats, especially in the calcareous soils of Southern Europe. Description The plant is a small deciduous tree or large shrub up to tall. It has smooth bark, dark green spreading branches and pendulous and pubescent twigs. The leaves are generally trifoliate and oval with long petioles, smooth on the upperside and hairy on the underside. It flowers during May and June. ''Laburnum anagyroides'' blooms in late spring with pea-like, yellow flowers densely packed in pendulous racemes 10–25 cm (4–10 in) long. The flowers are golden yellow, sweet scented, and typically bloom in May. The seeds are legumes with large numbers of black seeds that contain ...

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 ...
