Vasodilatory effects of 4-methyl catechol: ex vivo mechanism of action
Kuzdřalová, Kateřina ; Pourová, Jana (advisor) ; Smutná, Lucie (referee)
Charles University Faculty of Pharmacy in Hradec Králové Department of Pharmacology and Toxicology Student: Kateřina Kuzdřalová Supervisor: doc. PharmDr. Jana Pourová, Ph.D. Title of diploma thesis: The mechanism of vasodilation effect of 4-methylcatechol ex vivo Keywords: rat, aorta, flavonoids, 4-methylcatechol, vascular smooth muscle, vasodilation Flavonoids belong to the group of polyphenolic bioactive substances found abundantly in plants, fruits and vegetables. Thanks to their pharmacological and biochemical effects, they play a crucial role for human health, especially in the prevention of numerous diseases - metabolic syndrome, osteoporosis, atherosclerosis and also diseases of a cardiovascular system. The aim of the diploma thesis was to determine the mechanism of the vasorelaxant effect of one of the most important metabolites of flavonoids - 4-methylcatechol. For the research we used a standardized ex vivo method on isolated Wistar rat aortic rings. We were able to confirm the vasodilatory effects of 4-methylcatechol. We also confirmed the fact that the flavonoid metabolite directly affects a vascular smooth muscle. Furthermore, we found that the tested compound potentiates the vasodilatory activity of sodium nitroprusside and forskolin, and that vasodilation depends on the activity of...
