Chelation of copper ions by thiol containing chelators
Kladivová, Andrea ; Mladěnka, Přemysl (advisor) ; Carazo Fernández, Alejandro (referee)
Charles University Faculty of Pharmacy in Hradec Králové Department of Pharmacology & Toxicology Student: Andrea Kladivová Consultant: Václav Tvrdý, MSc. Supervisor: Assoc. Prof. Přemysl Mladěnka, PharmD., Ph.D. Title of diploma thesis: Chelation of copper ions by thiol containing chelators Copper is an essential trace element that is important for many physiological functions. On the other hand, disruption of copper homeostasis associated with its elevated level is dangerous for the organism, because of the formation of free radicals. Copper chelators can represent an effective tool in the treatment of such conditions. Due to the ability of a thiol group to bind metal ions and form a chelate, thiol containing chelators are promising compounds for the reduction of copper levels. Within this diploma thesis, four compounds containing a thiol group were tested for the ability to chelate copper ions. Spectrophotometric measurement was used for this determination. It is a simple, fast but precise method for determination of the chelation properties in vitro. In addition, the ability of these compounds to reduce cupric ions was examined. When using the basic hematoxylin method, all the tested substances proved they can chelate copper. Their efficacy was practically identical except for the...
