Charles University Faculty of Pharmacy in Hradec Králové Department of Pharmacology and Toxicology Candidate: Lukáš Konečný Supervisor: prof. Přemysl Mladěnka, Pharm.D., Ph.D. Title of Thesis: Preparation of a method for detection of the extent of chelation of calcium and magnesium ions Calcium and magnesium are biogenic elements belonging to the second group of the periodic table. Calcium is the fifth most abundant element in the human body. In addition to its important role in bone homeostasis, calcium is involved in other processes such as blood clotting, muscle contraction and regulation of nerve excitability Magnesium is the cofactor of many enzymatic reactions essential for a row of physiological functions. The aim of this work was to propose a novel screening method for determination of the degree of calcium and magnesium chelation. In the first step the UV-vis spectra of the selected indicator o-cresolphthalein complexone and its complexes with calcium and magnesium were measured. This was followed by verification of the linearity and the determination of the sensitivity of the method. Concurrently the stability of the indicator and its complexes with both ions was measured. In the last step, the suitability of the method was verified on a standard chelator ethylenediaminetetraacetic acid...
