Charles University in Prague Faculty of Pharmacy in Hradec Králové Department of Biochemical Sciences Candidate: Mgr. Eliška Potůčková Supervisor: Doc. PharmDr. Tomáš Šimůnek, Ph.D. Title of Doctoral Thesis: Study of antiproliferative effects of novel iron chelators Recent studies demonstrate that iron chelators possess marked potential as anticancer agents and also as substances protecting sensitive tissues against oxidative stress. This thesis is dealing mainly with design and synthesis of new antiproliferative iron chelators based on the structure of salicylaldehyde isonicotinoyl hydrazone (SIH) and with a characterization of their pharmacological and toxicological properties. Antiproliferative effects of these substances were studied on human breast adenocarcinoma cell line and human leukemic cell line and the non-specific toxicity on neonatal rat cardiac tissue-derived cells. During these studies some novel structure- activity relationships have been found. Furthermore, the suitability of simultaneous administration of iron chelators with antineoplastic agents used in breast cancer treatment was studied. In this project the anthracycline antibiotic, doxorubicin, and, in particular, the estrogen receptor antagonist, tamoxifen, were identified as the most suitable agents for potential treatment...
