Charles University Faculty of Pharmacy in Hradec Králové Department of Pharmaceutical Botany Candidate: Zuzana Lomozová Supervisor: PharmDr. Jana Karlíčková, Ph.D. Title of Thesis: Interactions of tamarixetin and isorhamnetin with copper Keywords: tamarixetin, isorhamnetin, chelation, reduction, copper, bathocuproine, hematoxylin Copper is a biogenic trace element important for proper function of human organism. It is an essential part of several enzymes and is involved in metabolic processes in the body. Excess or lack of serum copper can lead to pathological conditions. Copper chelating agents are used to treat copper toxic effects. Flavonoids are polyphenolic substances belonging to secondary metabolites of various plants. They are part of the human diet and have a positive impact on our health. They exhibit antioxidant and anti-inflammatory effects and are able to chelate transient metals, especially iron and copper. Chelation therapy is currently used in Wilson's disease in which copper is overloaded. In the future, the chelating effects of flavonoids could be used to treat neurodegenerative diseases, cardiovascular diseases or cancer. In this diploma thesis, interactions of two flavonoids (namely tamarixetin and isorhamnetin) with copper ions in different buffers were tested....
