| Summary: | Human organism has always been exposed to a vast array of chemicals encountered in the environment. Chemical revolution has significantly influenced biological evolution of humans leading to serious unpredictable toxicities. In response to continual chemical stress they have developed a variety of enzymes to transform these xenobiotics. Xenobiotics are mostly highly lipophilic and cannot readily be excreted from the body without metabolism to more hydrophilic, water-soluble metabolites. Not only environmental chemicals represent xenobiotics but also drugs, dietary components etc. Biotransformation studies play an important role in the drug discovery and development process. Usually data from drug metabolism is required before a new substance can advance towards the development stages of a new therapeutic agent. Data on metabolism is frequently used to optimize drug candidates, suggest more active compounds or support toxicology studies. The increased flux of new chemical entities into drug discovery has placed an increased need for fast and reliable information on the metabolism of these substances. Liquid chromatography coupled with mass spectrometry can meet demands for rapid drugs and metabolites analysis imposed by modern drug discovery strategies. This dissertation thesis presents an evidence... |
