Natural Products as Anticancer Agents introduces the different types of natural products that have been used for cancer treatment. Divided into four parts, covering anticancer agents derived from terrestrial plants, anticancer agents derived from the marine environment, and anticancer agents derived from microorganisms, as well as evaluation of new anticancer agents, each part includes discussion of the properties, synthesis/extraction, storage, mechanism of action, and usage of the molecules. Discussion of the future prospects in anticancer natural products—including several new trends and an indication of where research in this area is likely to go in the future—is also included.
