Course content
Content of lectures: 1. Introduction, definition of xenobiotic and xenobiochemistry, history, the fate of xenobiotics in the organism, transport, distribution, accumulation, metabolism and elimination. 2. I., II., and III. Phase of biotransformation, reactions and enzymes. 3. Cytochromes P450, FMO and other oxidative enzymes. 4. Reductive enzymes. 5. Reactions of II. phase of biotransformation. 6. Reactions of II. phase of biotransformation. 7. Factors influencing biotransformation. 8. Activation and inactivation of biotransformation enzymes (Ah receptors and other nuclear receptors). 9. Biotransformation in organs, organ toxicity. 10. Biotransformation in organs, organ toxicity. 11. Biotransformation in the foetus and placenta, toxicity and accumulation of xenobiotics in the foetus. 12. Examples of biotransformation of specific xenobiotics (drugs etc.). Ecotoxicology. Content of practicals: DNA damage detection, methods for detection of mutations, determination of activity of biotransforming enzymes, determination of mutations affecting the activity of biotransforming enzymes (e.g. CYP2D6, ADH, ALDH). Analytical methods in toxicology - LC-MS, GC-MS etc.
