Natural compounds, which have evolved their function over millions of years, are often more efficient than man-made compounds if a specific biological activity is needed, e.g. as an enzyme inhibitor or as a toxin to kill a cancer cell. This book comprising of sixteen technical chapters, highlights the chemical and biological aspects of potential natural products with an intention of unravelling their pharmaceutical applicability in modern drug discovery processes. Key features: Covers the synthesis, semi-synthesis and also biosynthesis of potentially bioactive natural products Features chemical and biological advances in naturally occurring organic compounds describing their chemical transformations, mode of actions, and structure-activity relationships 40 expert scientists from around the world report their latest findings and outline future opportunities for the development of novel and highly potent drugs based on natural products operating at the interface of chemistry and biology Forward-looking: Addresses opportunities and cutting-edge developments rather than well-documented basic knowledge, pinpoints current trends and future directions in this rapidly-evolving field Application-oriented: Throughout the book, the focus is on actual and potential applications in pharmacology and biotechnology This book is an essential resource for natural products chemists, medicinal chemists, biotechnologists, biochemists, pharmacologists, as well as the pharmaceutical and biotechnological industries.

Included are descriptions of the cutting-edge nuclear-magnetic-resonance and electron-paramagnetic-resonance spectroscopic techniques, the dynamics of ultra-fast reactions, and the central problem of molecular oxygen activation in biological processes. The roles of chiral auxiliaries in organic synthesis and of photochemistry in natural product synthesis are told, and innovations in combinatorial synthesis approaches are described. Contemporary issues in molecular recognition and modulation of molecular function are addressed, concluding with a missive regarding how the frontiers of medical ethics may be breached by molecular manipulations. The contributors, who number among the finest scientists in the world, including two Nobel Prize winners, are Peter B. Dervan, Jack D. Dunitz, Christian Griesinger, Jean-Marie Lehn, Thomas F. Prisner, Gerhard Quinkert, Peter G. Schultz, Helmut Schwarz, Dieter Seebach, and Ahmed Zewail. Additionally, there is a prologue by Albert Eschenmoser, for whom this collection was conceived, and an epilogue that contains facsimiles of notes from his landmark lecture 'Synthesis of Co-Enzyme B12: A Vehicle for Teaching Organic Synthesis'. This book is definitely a must for all who want to read, or to read again, where we stand in our chemical comprehension of the fascinating relationship between chemical structure and biological processes, how we got here, and what the future might hold.
