Search for an efficient cobalt chelator
Nosková, Karolína ; Mladěnka, Přemysl (advisor) ; Smutný, Tomáš (referee)
Charles University Faculty of Pharmacy in Hradec Králové Department of Pharmacology & Toxicology Student: Karolína Nosková Supervisor: prof. Přemysl Mladěnka, PharmD., Ph.D. Consultant: Monika Moravcová, MSc. Title of diploma thesis: Search for an efficient cobalt chelator Cobalt, as part of vitamin B12, is an essential trace element for human organism. However, long-term exposure to high doses leads to toxicity. Chronic cobalt intoxication is currently most commonly observed after the implantation of cobalt-containing prostheses, which in some cases do not work properly and cobalt is released from them by mechanical friction or corrosion. That not only leads to a local reaction, but cobalt ions also enter the blood and lymphatic circulation and thus cause a systemic reaction. The intoxication is then manifested by neurological, cardiovascular and endocrine symptoms, which can lead to irreversible changes or even to the death. However, a chelator that would be able to effectively and selectively bind cobalt and thus effectively treat intoxication is not available in clinical practice. The aim of this thesis was a search for an efficient cobalt chelator among known metal chelators. Chelation was measured in vitro by a method based on spectrophotometric detection of unchelated cobalt ions at...
