PharmDr. Jana Pourová, Ph.D. Consultant: Mgr. Petr Jošt. Ph.D. Title of diploma thesis: Study of the cytostatic effects of sulfur mustard Sulfur mustard (HD) belongs to blistering agents used in chemical warfare. It is a bifunctional alkylating agent that covalently modifies DNA. The cytostatic effect of HD is characterized by halting cell division without cell death. The duration for which a cell can remain in this state depends on the extent of DNA damage, which can subsequently be converted into a cytotoxic effect leading to cell death. The aim of the study was to determine the concentration range of HD gas that exhibits cytostatic effects and to investigate the sensitivity of HaCaT skin keratinocyte cells synchronized in the G1, S, and G2/M phases of the cell cycle to alkylating damage induction following release from cell cycle blockage. The cytostatic effect was observed only at very low concentrations, in the range of units of µmol.l-1 . In our experiments, a concentration of 2 µmol.l-1 of HD prevented cell proliferation for 2 days. Lower, submicromolar concentrations, had a stimulatory effect on cell proliferation, while higher concentrations of HD...
