Vasorelaxant activity of selected metabolites of quercetine on isolated rat aorta
Horáčková, Markéta ; Vopršalová, Marie (advisor) ; Pourová, Jana (referee)
Charles University in Prague Faculty of Pharmacy in Hradech Králové Department of Pharmacology and Toxicology Candidate: Mgr. Markéta Horáčková Supervisor: PharmDr. Marie Vopršálová, CSc. Title of rigorous thesis: The vasorelaxing effect of selected quercetin metabolites on isolated rat aorta Quercetin with its metabolites belongs into wide group called flavonoids, which are polyphenolic secondary metabolites of plants. This work, that is part extensive research ongoing in Department of Pharmacology and Toxicology of Faculty of Pharmacy in Hradec Králové, is focused on selected metabolites of propionic acid. In theoretical part I included characterisation of flavonoid group and their pharmacological effect. I also described morphology of blood-vessels and mechanisms of regulation of systemic circulation, because this work is about effect on blood-vessels. In experimental part we observed vasorelaxation effect of selected metabolites on isolated thoracic aorta of strain Wistar rat first. We compared effects of tested metabolites with quercetin, which was also included in experiment. As the most efficient metabolite was found 3-(3-hydroxyphenyl)propionic acid (3-HPPA). Its vasorelaxing effect was about one order bigger than quercetin and its other tested metabolites. 3-HPPA was selected for the...
