Receptor Chemistry Towards the Third Millennium is the result of papers presented at the 12th Camerino-Noordwijkerhout Symposium, held in Camerino, Italy in September 1999. Although much is known about the way ligands interact with receptors, which have now been isolated, characterized and cloned, many aspects still remain to be explored. In particular, differentiation into distinct subpopulations and the multiplicity of transduction processes offer more specific targets in the search for new drugs. This book will be of interest to medicinal chemists, pharmacologists, biochemists and neurologists and will also be a valuable source of reference for medical students and postgraduate students in related fields.
