Dočekalová L., Iron-chelating activity of selected alkaloids III, Diploma thesis, Charles University in Prague, Faculty of Pharmacy in Hradec Králové, Department of Pharmaceutical botanic and ecology, Hradec Králové, 2016, 60 pp. Iron is important trace element necessary for human organism. When excess it develops free radicals and structures of organism are harmed. It can lead to organ failure. Excess is solved with chelators, the most used is deferoxamine. But his terapeutic regimen is disadvantageous and it has a lot of side effects. That's reason for searching for substances with better features. This paper focuses on studium of iron-chelating activity of selected alkaloids from family Amaryllidaceae. Concretely, it's galanthamine, undulatine, buphanisine, caranine, 1-O- acetylbulbisine, homolycorine, tazettine, galanthamine, chlidanthine, ambelline, haemanthamine, haemanthidine, hamayne, 9-O-demethylgalanthine and lycoramine. As standard for comparison of activity was used deferoxamine. Activity was measured by spectrophotometer. As indicator was used ferrozine. Chelatation was measured for ferrous ionts and for total iron, where hydroxylamine as reduction agent was used. Ferrous ionts was measured also with pH alteration. Highest activity reached deferoxamine in all executed measurements. In...
