Flavonols and cardiovascular disease

Molecular Aspects of Medicine, 2010
Flavonols, and specially quercetin, are widely distributed in plants and are present in considerable amounts in fruits and vegetables. In addition to their anti-oxidant effect, flavonols interfere with a large number of biochemical signaling pathways and, therefore, physiological and pathological processes.

Flavonols: Direct new synthesis of 6-hydroxy-flavonols

Proceedings of the Indian Academy of Sciences - Section A, 1950
The synthesis of 6-hydroxy-flavonols has been effected by the Algar and Flynn oxidation of 2∶5-dihydroxy-, 2∶5∶2′-trihydroxy-, 2∶5∶4′-trihydroxy-chalkones and 6∶3′-dihydroxy- and 6∶4′-dimethoxy-flavanones by means of alkaline hydrogen peroxide. The flavonols obtained have been characterised by preparing their acetyl or methoxy derivatives.

The flavonols of tea

Journal of the Science of Food and Agriculture, 1956
AbstractThe flavonols quercetin‐3‐glucoside (isoquercitrin), kaempferol‐3‐glucoside (astragalin), quercetin‐3‐rhamnoglucoside (rutin), kaempferol‐3‐rhamnoglucoside, quercetin‐3‐rhamno‐diglucoside, and kaempferol‐3‐rhamnodiglucoside, previously isolated and characterized in Japanese green teas, have also been detected in unprocessed tea‐leaf and black ...

Flavones and flavonols

1982
Most reports on the identification of known flavonoids in new plant sources as well as those on novel flavonoids naturally deal with the two most abundant classes, the flavones and flavonols. For this chapter we have listed all references to the occurrence of flavone and flavonol aglycones which have appeared from 1975 to 1980, and also include such ...

New Genera of Flavonols and Flavonol Derivatives As Therapeutic Molecules

Journal of the Korean Society for Applied Biological Chemistry, 2011
Natural products from plants and microorganisms traditionally have provided the pharmaceutical industry with one of the most important sources of “lead” compounds in the search for new drugs and medicines. The diversity of polyphenol structure is enormous.

Antinociceptive effect of flavonol and a few structurally related dimethoxy flavonols in mice

Inflammopharmacology, 2019
Previous reports suggest flavonoids as potent analgesic compounds. Based on these observations, the present study investigated the antinociceptive action of flavonol, 3', 4'-dimethoxy flavonol, 6, 3'-dimethoxy flavonol, 7, 2'-dimethoxy flavonol, and 7, 3'-dimethoxy flavonol and the possible mechanisms involved in these effects.

Flavonols from Bauhinia malabarica

Journal of Natural Medicines, 2008
Bauhinia malabarica Roxb. has been used in Thai traditional medicine for wound healing, as a diuretic, to fight dysentery and as an emmenagogue. Seven flavonols, including 6,8-di-C-methylkaempferol 3-methyl ether, kaempferol, afzelin, quercetin, isoquercitrin, quercitrin, and hyperoside were isolated from the methanol extract of leaves.

Synthesis of Flavonols via Pyrrolidine Catalysis: Origins of the Selectivity for Flavonol versus Aurone

The Journal of Organic Chemistry, 2020
A novel synthetic method for flavonol from 2'-hydroxyl acetophenone and benzaldehyde promoted by pyrrolidine under an aerobic condition in water is established. This protocol was supported by efficient synthesis of 44 common examples and three natural products.

INHERITANCE OF FLAVONOL GLYCOSIDES IN SOYBEANS

Canadian Journal of Genetics and Cytology, 1973
Genetic analysis detected three genes that are involved in the formation of various flavonol glycosides in the leaves of soybeans (Glycine max (L.) Merrill). Eight flavonol classes were observed with each gene showing dominance for glycoside formation. The gene symbols Fg1and fg1, Fg2and fg2, and Fg3and fg3are proposed.

Understanding the Cardioprotective Effects of Flavonols: Discovery of Relaxant Flavonols without Antioxidant Activity

Journal of Medicinal Chemistry, 2008
3',4'-Dihydroxyflavonol (DiOHF) is a cardioprotective flavonol that can reduce injury after myocardial ischemia and reperfusion and thus is a promising small molecule for the treatment of cardiovascular disease. Like all vasoactive flavonols reported to date, DiOHF is both relaxant and antioxidant, hindering investigation of the relative contribution ...
