This volume will cover the natural products as they relate to cancer chemotherapy. The topics will include history and current status , recent launches, new clinical candidates and approved drugs directly derived from natural products, current and future cancer target opportunities for natural products, leveraging natural products as tools for new target generation , new approaches to cancer drug discovery through natural products based lead generation, and enabling technologies which leverage the unique attributes of natural products.

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.

Natural products, with remarkable chemical diversity have played a dominant role in the treatment of human ailments. They are considered as a reservoir of bioactive compounds and are extensively investigated for their therapeutic potentials, most notably in the area of cancer therapy. They cannot function as effective drugs in isolation but they can be converted into a drug through chemical modification. There are a variety of widely-used anticancer agents that originate from natural sources, which are structurally unique and function by novel action mechanisms. Some examples of these natural anticancer agents are camptothecin, irinotecan, vincristine, etoposide and paclitaxel derived from plants; actinomycin D and mitomycin C obtained from bacteria; as well as marine-derived bleomycin. Camptothecin is a naturally occurring quinolone alkaloid isolated from wood and bark of Camptotheca acuminate. It is used as a chemotherapeutic agent for treating leukemia. This book is a compilation of chapters that discuss the most vital concepts and emerging trends in the discovery and development of anti-cancer agents from natural products. It includes contributions of experts and scientists which will provide innovative insights into this area of study.

The reader will discover a comprehensive and multifaceted overview of the history of the development of anticancer drugs deeply influenced by the cell concept of cancer and future directions for the development of new anticancer drugs. First, this book documents the scientific progress in biological science over the last 70 years and the influence this progress had in cancer research. Summaries and charts of important discoveries complete this overview. Furthermore, this book outlines the process of anticancer drug development with a focus on the characteristic drug groups of each era, related to advancements of chemistry and biological sciences. This book also provides brief mechanism of action of drugs, illustrated by comprehensive timelines and conceptual cartoons. This book finally sums up the limitations of the current anticancer drug development and seeks new directions for anticancer drug discovery, considering under the systemic view of cancer.

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

With the publication of these proceedings from the Second Drug Discovery and Development Symposium, this forum has become the main mechanism for bringing together the principal groups involved in both discovering and developing new approaches to the treatment of cancer. This Second Symposium emphasized the types of materials being discovered and their therapeutic activity. This is especially evident in the natural product discovery programs, where unique and active structures are being identified. The major contributors to the meeting were the investigators participating in the National Cooperative (Natural Products) Drug Discovery Groups [NC(NP)DDG]. These groups reflect an association among researchers at universities or cancer centers, pharmaceutical companies and the National Cancer Institute. Their sources of materials are varied, reflecting chemical inventories of pharmaceutical companies, organic synthetic compounds from the laboratory, cytotoxics as well as biologics and their hybrids, and natural products obtained from plants, marine organisms and microorganisms. The models employed in the discovery systems vary from broadly cellular based to specific enzymes to defined cellular functions. Each of them is believed important to the malignant state and will allow for the discovery of compounds which will have efficacy in cancer therapy. The goal of the participants is both to discover new anticancer agents and to develop them as efficiently as possible into clinically useful additions to treatment. Of importance is the fact that there are a number of promising leads which will soon be moving into the clinic thereby testing the effectiveness of this NC (NP) DDG approach.
