Interactions of natural phenolic compounds with biogenic metals
Lomozová, Zuzana ; Mladěnka, Přemysl (advisor) ; Bittner Fialová, Silvia (referee) ; Patočka, Jiří (referee)
Charles University, Faculty of Pharmacy in Hradec Králové Department of Pharmacognosy and Pharmaceutical Botany Candidate: Zuzana Lomozová, MSc. Supervisor: Prof. Přemysl Mladěnka, PharmD., Ph.D. Title of Doctoral Thesis: Interactions of natural phenolic compounds with biogenic metals Phenolic compounds are one of the most widely distributed groups of secondary plant metabolites. They are an integral part of the human diet and their consumption is associated with a number of positive effects. They include a wide range of substances, from simple molecules such as phenolic acids to large polymeric compounds such as tannins. Because of their structure, which includes, among others, free hydroxyl groups, they are able to interact with biogenic metals and form metal complexes with them. Under normal conditions, the homeostasis of these transition metals in the body is tightly regulated, but it can be disturbed in pathological conditions such as acute myocardial infarction, when the levels of free iron and copper increase as a result of a significant decrease in pH. Similar metal imbalance is observed as well as in inflammatory and neurodegenerative diseases, tumours, or diabetes mellitus. The aim of this dissertation was to find out how these substances react with biogenic metals using in vitro and ex...
