Book Description
Enediynes are natural products with highly active cytotoxicity and antibacterial activity, and thus have significant potential in the development of anti-cancer treatments. However, they are not readily available and can degrade rapidly during isolation; one solution is to produce them using total synthesis.Dynemicin A and uncialamycin are two such enediynes, with similar structures, for which total synthesis has been achieved. This book presents the isolation and preparation of these two compounds and their analogues through various synthesis strategies. Details of the structural elements essential to their anti-cancer activity are presented, with the objective of explaining and optimizing their biological activities and potential development as drugs. - Presents two natural ènediynes with similar structures whose total syntheses have been accomplished - Explores structural analogs of preparation for purposes of optimizing the anti-cancer activity - Describes the total syntheses of dynemicin A, the uncialamycine, as well as analogs by emphasizing the synthesis strategies adopted - Features studies of the biological activities and data to bring out the structural elements of these essential compounds

Book Description
Biphasic Chemistry and The Solvent Case examines recent improvements in reaction conditions, in order to affirm the role of chemistry in the sustainable field. This book shows that those who work within the chemistry industry support limits for the use of toxic or flammable solvents, since it reduces the purifications to simple filtrations. Thanks to commercial scavengers, solid phase syntheses are now available to all. Fluorine biphasic catalysis enables extremely efficient catalyst recycling and has a high applicability potential at the industrial level. This book also reviews the many studies that have shown that water is a solvent of choice for most synthetic reactions. Particular traits can be obtained and the effects on thermodynamics make it possible to operate at lower temperatures, thereby achieving energy savings. Finally the great diversity of application of the reactions without solvents is illustrated.

Book Description
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

Book Description
Demonstrates the advantages of catalytic cascade reactions for synthesizing natural products and pharmaceuticals Riding the wave of green chemistry, catalytic cascade reactions have become one of the most active research areas in organic synthesis. During a cascade reaction, just one reaction solvent, one workup procedure, and one purification step are needed, thus significantly increasing synthetic efficiency. Featuring contributions from an international team of pioneers in the field, Catalytic Cascade Reactions demonstrates the versatility and application of these reactions for synthesizing valuable compounds. The book examines both organocatalysis and transition-metal catalysis reactions, bringing readers up to date with the latest discoveries and activities in all major areas of catalytic cascade reaction research. Catalytic Cascade Reactions begins with three chapters dedicated to organocatalytic cascade reactions, exploring amines, Brønsted acids, and the application of organocatalytic cascade reactions in natural product synthesis and drug discovery. Next, the book covers: Gold-catalyzed cascade reactions Cascade reactions catalyzed by ruthenium, iron, iridium, rhodium, and copper Palladium-catalyzed cascade reactions of alkenes, alkynes, and allenes Application of transition-metal catalyzed cascade reactions in natural product synthesis and drug discovery Engineering mono- and multifunctional nanocatalysts for cascade reactions Multiple-catalyst-promoted cascade reactions All chapters are thoroughly referenced, providing quick access to important original research findings and reviews so that readers can explore individual topics in greater depth. Drawing together and analyzing published findings scattered across the literature, this book provides a single source that encapsulates our current understanding of catalytic cascade processes. Moreover, it sets the stage for the development of new catalytic cascade reactions and their applications.
