PHARMACEUTICAL, MEDICINAL AND NATURAL PRODUCT CHEMISTRY provides an overview of structural features and functional groups of different classes of pharmacologically active natural products, synthetic drugs and drugs from microorganisms, animals and plants and their biological activities. The text presents the concepts which are central to the study of drug action of the natural materials themselves and as lead compounds and drug production (DNA Recombinant Technology) supported by logical chemical, biochemical and mechanistic principles. The material presented guides the reader through biosynthetic and metabolic pathways, which demonstrates their unique integration. The book also contains material on the synthesis of some drugs structure, synthesis, biosynthesis and conformational analysis of some of the more important members of terpenoids, steroids, carotenoid alkaloids, flavanoids, purine and pyrimidines along with their medicinal significance. Students of organic chemistry, pharmacy and medicinal chemistry will find this book an invaluable source.
