Medicinal and natural product chemistry is generally considered as a discipline concerned with biological molecules but it is essentially the chemistry of carbon compounds. A large number of organic compounds are either derived or completely synthesized in laboratories. This book discusses many such advanced compounds, their manufacturing processes, structures and properties. Some of the topics included are drug design to combinatorial synthesis and parallel synthesis, applications of compound collections, compound preparation, molecular diversity assessments, etc. The ever growing need for advanced technology is the reason that has fueled the research in this field in recent times. Such selected concepts that redefine medicinal and natural product chemistry have been presented in this book. The extensive content presented in the book provides the readers with a thorough understanding of this subject. It will serve as a resource guide for professionals, researchers and students engaged in this field.
