Riassunto

This edition of the Proceedings of the 9th European Symposium on Structure-Activity Relationships: QSAR and Molecular Modelling held from September 7-11, 1992 in Strasbourg, France deals with various areas of structure-activity relationships and their applications in the design of new drugs. The approximately 175 contributions in the book highlight the interdisciplinary approach between QSAR, molecular modelling and databank-based research in the design and development process of new drug candidates, and demonstrates the efficacy of these techniques by introducing rationalization at a very early stage in the discovery of bioactive compounds.
Internationally renowned specialists review methodologies in the field of SAR concepts and computer-assisted drug design, covering such topics as:

• De novo design
• X-ray and NMR-based drug design
• Parameters and interactions.
• Molecular modelling
• Molecular similarity
• 3D QSAR.
