The aim of the subject Bioorganic chemistry is to broaden the PhD students´ knowledge of drug interactions with natural compounds and possibilities to influence these interactions through chemical modifications. The subject includes two main topics: chemistry of natural compounds (proteins, saccharides, nucleic acids and lipids) and drug development and their behavior in the organism (for example, structure optimization, drug behavior in the organism, physicochemical properties of drugs and non-covalent interactions between drug and its target).
