The process of inventing and finding new medications on the basis of the knowledge of a biological target is called drug design. The chemical substances which activate or inhibit the functions of a biomolecule, and consequently result in therapeutic benefits to the patients are called drugs. They are usually obtained through extraction from several medicinal plants or by organic synthesis. Drug design is a process involving the design of such molecules which are similar in the shape and charge to the biomolecular target with which they interact, in order to bind to it. This book brings forth some of the most innovative concepts and elucidates the unexplored aspects of drug design and analysis. Different approaches, evaluations, methodologies and advanced studies on drug design and analysis have been included in it. The extensive content of this book provides the readers with a thorough understanding of the subject.
