Manganese and iron flavonolates as flavonol 2,4-dioxygenase mimics

Chemical Communications, 2007
Mononuclear manganese(II) and iron(III) flavonolates were synthesized as synthetic enzyme-substrate complexes, and their oxygenation reactions as biomimetic functional models with relevance to flavonol 2,4-dioxygenases are briefly described.

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.

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.

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 ...
