Isorhamnetin
Isorhamnetin is the methylated metabolite of quercetin. Quercetin is an important dietary flavonoid with in vitro antioxidant activity. However, it is found in human plasma as conjugates with glucuronic acid, sulfate or methyl groups, with no significant amounts of free quercetin present. Isorhamnetin prevents endothelial cell injuries from oxidized LDL via inhibition of lectin-like ox-LDL receptor-1 upregulation, interference of ox-LDL-mediated intracellular signaling pathway (p38MAPK activation, NF-kappaB nuclear translocation, eNOS expression) and the antioxidant activity of isorhamnetin. Isorhamnetin prevents endothelial dysfunction, superoxide production, and overexpression of p47phox induced by angiotensin II. Isorhamnetin appears to be a potent drug against esophageal cancer due to its in vitro potential to not only inhibit proliferation but also induce apoptosis of Eca-109 cells. (PMID: 15493462, 17368593, 17374653, 16963021). Isorhamnetin is a monomethoxyflavone that is quercetin in which the hydroxy group at position 3 is replaced by a methoxy group. It has a role as an EC 1.14.18.1 (tyrosinase) inhibitor, an anticoagulant and a metabolite. It is a 7-hydroxyflavonol, a tetrahydroxyflavone and a monomethoxyflavone. It is functionally related to a quercetin. It is a conjugate acid of an isorhamnetin(1-). Isorhamnetin is a natural product found in Lotus ucrainicus, Strychnos pseudoquina, and other organisms with data available. Isorhamnetin is a metabolite found in or produced by Saccharomyces cerevisiae. See also: Peumus boldus leaf (part of). Widespread flavonol found especially in bee pollen, chives, corn poppy leaves, garden cress, fennel, hartwort, red onions, pears, dillweed, parsley and tarragon. Isorhamnetin is found in many foods, some of which are italian sweet red pepper, carrot, yellow wax bean, and lemon balm. A monomethoxyflavone that is quercetin in which the hydroxy group at position 3 is replaced by a methoxy group. Acquisition and generation of the data is financially supported in part by CREST/JST.

Tricin
3,5-di-O-methyltricetin is the 3,5-di-O-methyl ether of tricetin. Known commonly as tricin, it is a constituent of rice bran and has been found to potently inhibit colon cancer cell growth. It has a role as an EC 1.14.99.1 (prostaglandin-endoperoxide synthase) inhibitor and a metabolite. It is a trihydroxyflavone, a dimethoxyflavone and a member of 3-methoxyflavones. It is functionally related to a tricetin. It is a conjugate acid of a 3,5-di-O-methyltricetin(1-). Tricin is a natural product found in Carex fraseriana, Smilax bracteata, and other organisms with data available. See also: Arnica montana Flower (part of); Elymus repens root (part of). The 3,5-di-O-methyl ether of tricetin. Known commonly as tricin, it is a constituent of rice bran and has been found to potently inhibit colon cancer cell growth. Isolated from Triticum dicoccum (emmer). Tricin 5-diglucoside is found in wheat and cereals and cereal products. From leaves of Oryza sativa (rice). 5,7-dihydroxy-2-(4-hydroxy-3,5-dimethoxyphenyl)-4h-chromen-4-one, also known as 3,5-O-dimethyltricetin or 5,7,4-trihydroxy-3,5-dimethoxy-flavone, is a member of the class of compounds known as 3-o-methylated flavonoids. 3-o-methylated flavonoids are flavonoids with methoxy groups attached to the C3 atom of the flavonoid backbone. Thus, 5,7-dihydroxy-2-(4-hydroxy-3,5-dimethoxyphenyl)-4h-chromen-4-one is considered to be a flavonoid lipid molecule. 5,7-dihydroxy-2-(4-hydroxy-3,5-dimethoxyphenyl)-4h-chromen-4-one is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). 5,7-dihydroxy-2-(4-hydroxy-3,5-dimethoxyphenyl)-4h-chromen-4-one can be synthesized from tricetin. 5,7-dihydroxy-2-(4-hydroxy-3,5-dimethoxyphenyl)-4h-chromen-4-one is also a parent compound for other transformation products, including but not limited to, tricin 7-O-glucoside, 4-O-beta-glucosyl-7-O-(6-O-sinapoylglucosyl)tricin, and tricin 7-O-(6-O-malonyl)-beta-D-glucopyranoside. 5,7-dihydroxy-2-(4-hydroxy-3,5-dimethoxyphenyl)-4h-chromen-4-one can be found in barley, common wheat, oat, and rice, which makes 5,7-dihydroxy-2-(4-hydroxy-3,5-dimethoxyphenyl)-4h-chromen-4-one a potential biomarker for the consumption of these food products.
