Plants, marine organisms, and microorganisms have evolved complex chemical defense and signaling systems that are designed to protect them from predators and provide other biological benefits. These organisms thus produce substances containing novel chemotypes that may have beneficial effects for humans. As collection methods improve and new screen

The approach to drug discovery from natural sources has yielded many important new pharmaceuticals inaccessible by other routes. In many cases the isolated natural product may not be an effective drug for any of several reasons, but it nevertheless may become a drug through chemical modification or have a novel pharmacophore for future drug design. In summarizing the status of natural products as cancer chemotherapeutics, Anticancer Agents from Natural Products, Second Edition covers the: History of each covered drug—a discussion of its mechanism on action, medicinal chemistry, synthesis, and clinical applications Potential for novel drug discovery through the use of genome mining as well as future developments in anticancer drug discovery Important biosynthetic approaches to "unnatural" natural products Anticancer Agents from Natural Products, Second Edition discusses how complex target-oriented synthesis—enabled by historic advances in methodology—has enormously expanded the scope of the possible. This book covers the current clinically used anticancer agents that are either natural products or are clearly derived from natural product leads. It also reviews drug candidates currently in clinical development since many of these will be clinically used drugs in the future. Examples include the drugs etoposide and teniposide derived from the lead compound podophyllotoxin; numerous analogs derived from taxol; topotecan, derived from camptothecin; and the synthetic clinical candidates, E7389 and HTI-286, developed from the marine leads, halichondrin B and hemiasterlin.

Medicinal Chemistry of Anticancer Drugs, Second Edition, provides an updated treatment from the point of view of medicinal chemistry and drug design, focusing on the mechanism of action of antitumor drugs from the molecular level, and on the relationship between chemical structure and chemical and biochemical reactivity of antitumor agents. Antitumor chemotherapy is a very active field of research, and a huge amount of information on the topic is generated every year. Cytotoxic chemotherapy is gradually being supplemented by a new generation of drugs that recognize specific targets on the surface or inside cancer cells, and resistance to antitumor drugs continues to be investigated. While these therapies are in their infancy, they hold promise of more effective therapies with fewer side effects. Although many books are available that deal with clinical aspects of cancer chemotherapy, this book provides a sorely needed update from the point of view of medicinal chemistry and drug design. - Presents information in a clear and concise way using a large number of figures - Historical background provides insights on how the process of drug discovery in the anticancer field has evolved - Extensive references to primary literature

While drug therapies developed in the last 80 years have markedly improved treatment outcomes and the management of some types of cancers, the lack of effectiveness and side effects associated with the most common treatment types remain unacceptable. However, recent technological advances are leading to improved therapies based on targeting distinct biological pathways in cancer cells. Chemistry and Pharmacology of Anticancer Drugs is a comprehensive survey of all families of anticancer agents and therapeutic approaches currently in use or in advanced stages of clinical trials, including biological-based therapies. The book is unique in providing molecular structures for all anticancer agents, discussing them in terms of history of development, chemistry, mechanism of action, structure–function relationships, and pharmacology. It also provides relevant information on side effects, dosing, and formulation. The authors, renowned scientists in cancer research and drug discovery, also provide up-to-date information on the drug discovery process, including discussions of new research tools, tumor-targeting strategies, and fundamental concepts in the relatively new areas of precision medicine and chemoprevention. Chemistry and Pharmacology of Anticancer Drugs is an indispensable resource for cancer researchers, medicinal chemists and other biomedical scientists involved in the development of new anticancer therapies. Its breadth of coverage, clear explanations, and illustrations also make it suitable for undergraduate and postgraduate courses in medicine, pharmacy, nursing, dentistry, nutrition, the biomedical sciences, and related disciplines. Key Features: Summarizes the fundamental causes of cancer, modes of treatment, and strategies for cancer drug discovery Brings together a broad spectrum of information relating to the chemistry and pharmacology of all families of anticancer agents and therapies Includes up-to-date information on cutting-edge aspects of cancer treatments such as biomarkers, pharmacogenetics, and pharmacogenomics Features new chapters on the "Evolution of Anticancer Therapies", "Antibody-Based Therapies", and "Cancer Chemoprevention"

This book is a printed edition of the Special Issue "Natural Products for Cancer Prevention and Therapy" that was published in Nutrients

Evolutionary Diversity as a Source for Anticancer Molecules discusses evolutionary diversity as source for anticancer agents derived from bacteria, algae, bryophytes, pteridophytes, and gymnosperms. The book goes over the isolation of anticancer agents and the technologyenabled screening process used to develop anticancer drugs. The book also includes discussion of the nutraceuticals and natural productsderived from invertebrates that can be used as part of cancer treatment. Evolutionary Diversity as a Source for Anticancer Molecules also deals with some of the current challenges in the prevention of cancer as well as the side effects of conventional drugs used for cancer patients.This book is a valuable resource for cancer researchers, oncologists, biotechnologists, pharmacologists, and any member of the biomedicalfield interested in understanding more about natural products with anticancer potential. - Discusses the application of natural products in place of conventional drugs to minimize the side effects in cancer treatment - Explains the relation between evolutionary mechanisms and climate change for production of secondary metabolites
