Assuming little previous knowledge of biology, this book aids graduate chemists to close the gap in their knowledge of pharmacology and make the link between medicinal chemistry and the way in which drugs act on the body. The availability of receptor structures has revolutionised drug discovery and development necessitating an up-to-date source of information for chemists entering this new pharmacological world. Chapters explain the history of pharmacology, the relationship between receptor structure and function and receptor pharmacology relevant to drug design. This unique textbook will be an essential resource for chemists planning to work in drug discovery, or postgraduate students and practising chemists interested in expanding their pharmacology knowledge.
