Focusing on visible light-driven organic synthesis, this comprehensive volume explores cutting-edge research and methodologies in the field. It details over 100 synthetic strategies, emphasizing reactions that form carbon-carbon and carbon-heteroatom bonds under mild conditions. Each chapter is dedicated to specific photocatalysts, presenting reaction types, conditions, mechanisms, and examples in a structured format. Additionally, it covers self-sensitized transformations that require no external photocatalysts. This resource is invaluable for students, researchers, and industry professionals seeking the latest advancements in organic synthesis.

The book explores the evolution of organic synthesis in the chemical industry, highlighting the shift towards sustainable practices. It addresses the historical reliance on hazardous substances in producing organic compounds and emphasizes the need for safer alternatives. By focusing on efficient methods that minimize toxic reagents, harsh conditions, and costly catalysts, the text advocates for a more environmentally friendly approach to organic synthesis, reflecting a growing awareness of safety and sustainability in chemical processes.

Focusing on the molecular mechanisms of powerful naturally occurring agents and their implication for drug discovery, this timely book presents an overview of the most recent research advances in the field of bioactive natural products and natural drug formulations to combat today's destructive diseases. To this extent, the authors discuss the most severe neurological disorders in our modern civilization, such as Alzheimer's, Parkinson's and Huntington's disease, as well as ischemic brain stroke and depression. The emerging diversity of active compounds is covered in detail, including flavonoids, cannabinoids and oleanolic acid, while experts in the field explain the chemistry, mode of action and clinical aspects of novel neuroprotective natural products. In each case, the benefits of treatments using natural products are addressed from the perspective of modern as well as traditional medicine. With its multidisciplinary viewpoint, this is the ideal companion for medicinal and natural products chemists as well as neuroscientists, biochemists, pharmacologists, neurobiologists, and phytotherapists.

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. The synthesis, semi-synthesis and also biosynthesis of potentially bioactive natural products are covered. It also 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. This book is aimed at natural products chemists, medicinal chemists, biotechnologists, biochemists, pharmacologists, as well as the pharmaceutical and biotechnological industries.

In a classical alphabetical format, this two-volume reference covers more than 1000 painstakingly screened natural product structures. For each compound or compound class, a basic chemical characterization is given, followed by a description of the biological source and a discussion of their pharmaceutical potential as lead molecules for new drugs. The latter takes into account the documented uses of many of these compounds in Asian traditional medicine. By way of its clearly structured, single-page articles, and with the aid of classification tables in the appendix, this dictionary is easy to use and provides quick and reliable information researchers as well for scholars and students.
