KD2400 Bioactive Molecules 6.0 credits

Bioaktiva molekyler

Course on bioactive molecules, including their chemical characterization and mechanisms of action. The aim of the course is to work with natural products and give students experience in practical use of preparative and analytical separation methods including GC-MS and LC andLC-MS. Bioactivity of fractions obtained will be tested on various organisms such as insects and microbes.  

Offering and execution

Course offering missing for current semester as well as for previous and coming semesters

Course information

Content and learning outcomes

Course contents *

  • Methods how to determine bioactivity
  • Chemical, farmacological, biological tools for determining bioactive molecules
  • The wide structural range of bioactive molecules
  • Natural products as an important area for new lead compounds in the development of new drugs
  • Selected mechanisms of bioactivity, e.g. electrophysiology, ion channels,
  • Applications in pharmacology, chemical ecology,environmental toxicology, atompheric chemistry

Intended learning outcomes *

After the course the student should be able to:

  • Give examples of important areas where bioctive compounds are involved
  • give examples of the diversity in structure and bioactivity
  • follow the general route how to identify bioactive molecules
  • practically use the main instruments for identifying molecules
  • practically use main methods to test bioactivity
  • understand the evolutionary and molecular background for bioactivity (selected cases)
  • evaluate the importance of doses in relation to bioactivity
