Charles University, Faculty of Pharmacy in Hradec Králové Department: Department of Pharmacology and Toxicology Candidate: Mgr. Marcel Hrubša Supervisor: Prof. PharmDr. Přemysl Mladěnka, Ph.D. Title of dissertation thesis: The influence of metabolites and their parent phenolic compounds on blood platelets Acute cardiovascular events (ACEs), such as stroke and acute coronary syndromes encompassing acute myocardial infarction, are one of the main causes of cardiovascular mortality in the world. Current pharmacotherapy focuses primarily on secondary prevention of their recurrence, where antiplatelet drugs play a key role. These drugs reduce platelet hyperreactivity, which is present in the majority of cardiovascular and metabolic diseases, and significantly decrease the risk of ACEs. However, the palette of currently available drugs faces many issues, such as resistance, high variability in both pharmacokinetics and pharmacodynamics, serious side effects and the route of administration. This thesis firstly briefly summarizes the current knowledge of platelet physiology along with available antiplatelet drugs and their mechanism of action. Second part of the theoretical introduction is dedicated to polyphenolic compounds, as polyphenol-rich diet is associated with many beneficial effects, particularly...

Electrochemistry of Flavonolignans and their Interactions with DNA and Proteins
Pyszková, M. ; Zatloukalová, M. ; Biedermann, David ; Křen, Vladimír ; Ulrichová, J. ; Ramešová, Šárka ; Sokolová, Romana ; Vacek, J.
Electrochemical oxidation of flavonolignans silybin, silydianin, silychristin and their 2,3-dehydroderivatives, was studied using ex situ and in situ cyclic and square wave voltammetry at pyrolytic graphite electrode. The pilot results presented here could be used for further investigation of mechanism of oxidation and reactivity of flavonolignans to DNA and proteins.
