Ames test in the drug development
Klaučová, Martina ; Pávek, Petr (advisor) ; Konečná, Klára (referee)
Charles University Faculty of Pharmacy in Hradec Králové Department of Pharmacology and Toxicology Student: Martina Klaučová Supervisor: prof. PharmDr. Petr Pávek, Ph.D. Consultant: PharmDr. Ivona Pávková, Ph.D. Diploma thesis title: Ames test in the drug development Background: Thesis objective is the determination of potential genotoxicity of newly developed drugs within primary testing and the introduction of the Ames microfluctuation test which can be used in common laboratory conditions. Methods: I used commercially supplied kit based on the principles of Ames test which detects reverse mutation through colour changes of the samples using bacterial strains S. typhimurium. At first I had to study literary sources and then I could design the procedures of the Ames microfluctuation test, preparation of the chemicals and storage of the strains which are optimal for all laboratories. Results: The drug samples T6445 and T6447 with 30 µM concentration tested by metabolic activation S9 on bacterial strain ST TA 98 show genotoxicity. The sample UOCHB1 with 30 µM concentration tested without activation shows possible genotoxicity on both strains ST TA 98 and ST TA 100. Other samples do not show any toxicity. I used 3 different procedures during the designation of assay. The most suitable version of the...
