註釋 Drug design is a multi-disciplinary activity involving chemists, biologists, bochemists, mpharmacologists and many others. the chemist's role is central in inventing new compounds which exert a beneficial effect. However, once a lead for a new active drug has been established, its effective delivery has to be demonstrated and extensive toxikological studies undertaken to demonstrate its safety before cinical trials can commence. The metabolic fate of the drug has to be revealed and detailed distribution studies carried out in order to satisfy the regulatory authorities before the new compound can be marketed. Comprehensive Medicinal Chemistry describes all these aspects of the design of a drug whilst centering on the chemical mechanism whereby such agents act. Volume 4 covers quantitaive drug design.
