Students will be given an introduction to the principles of drugs design. This will include an analysis of the principles of identification of new compounds with the potential to be drugs, and their development for therapeutic use, and quantification of drug efficacy. Students will develop the ability to critique the importance of drug-receptor affinity and selectivity. The economic, social and ethical aspects of drug discovery will be analysed and discussed. Lectures in specialised areas will be given by experts in their field, providing a sense of the frontiers of their subject. In addition to formal lectures, the course will provide seminars and tutorials with opportunities to critically examine research papers.
