Flavonoids as Potent Scavengers of Hydroxyl Radicals.
Jakub Treml,Karel Šmejkal +1 more
TL;DR: Flavonoids, as natural plant antioxidants and essential component of the human diet, are reviewed as compounds interacting with the production of hydroxyl radicals and the structure of the flavonoids is discussed.
Journal ArticleDOI
Cholinesterase inhibitory activities of some flavonoid derivatives and chosen xanthone and their molecular docking studies.
Mahmud Tareq Hassan Khan,Ilkay Erdogan Orhan,Fatma Sezer Senol,Murat Kartal,Bilge Sener,Margita Dvorská,Karel Šmejkal,Tereza Šlapetová +7 more
TL;DR: In vitro inhibitory activities of four flavonoid derivatives of quercetin, rutin, kaempferol 3-O-beta-D-galactoside and macluraxanthone are examined to show a concentration-dependant inhibition of acetylcholinesterase and BChE and several strong hydrogen bonds to several important amino acid residues of both the enzymes were showed.
Journal ArticleDOI
