Titelbeschreibung

A comprehensive introduction to inorganic chemistry and, specifically, the science of metal-based drugs, Essentials of Inorganic Chemistry describes the basics of inorganic chemistry, including organometallic chemistry and radiochemistry, from a pharmaceutical perspective. Written for students of pharmacy and pharmacology, pharmaceutical sciences, medicinal chemistry and other health-care related subjects, this accessible text introduces chemical principles with relevant pharmaceutical examples rather than as stand-alone concepts, allowing students to see the relevance of this subject for their future professions. It includes exercises and case studies.

Rezension

“It would be a useful adjunct to more general chemistry texts for students in first and second years of study in pharmacy, pharmaceutical sciences, and medicinal chemistry, providing a framework to structure the more detailed but less contextualised information on inorganic pharmaceuticals they will doubtless be looking up on the internet.” (Chemistry in Australia, 1 October 2015)

Medicinal inorganic chemistry is an area of numerous clinical developments and has become very prominent with the discovery of platinum-based anticancer drugs. Currently used clinical applications are not only limited to platinum-based drugs, but indeed encompass a majority of elements found in the periodic table of elements. Therefore, it is crucial that professionals in a variety of healthcare settings have a basic understanding of inorganic chemistry in order to handle the relevant metal-based therapeutics in the correct manner. Essentials of Inorganic Chemistry For Students of Pharmacy, Pharmaceutical Sciences and Medicinal Chemistry, introduces the basic principles of inorganic chemistry and the science of metal-based drugs, using pharmacy-relevant examples. Each chapter deals with a group of elements, including the relevant chemical basics, and discusses clinically used examples. Within each chapter, the main inorganic principles or definitions are highlighted in feature boxes. Topics covered include: • Lithium based drugs – their role in the treatment of bipolar disorder • Organosilicon drugs – a modern alternative to traditional organic drugs • Salvarsan – the origin of chemotherapy • Platinum and other transition metal-based anticancer agents • Lanthanoids and their clinical use • Radiopharmacy • Chelation therapy Each chapter is complemented by a series of exercises and problem-based learning case studies to support self-directed studies, with additional materials available online at <a href="http://www.wiley.com/go/strohfeldt/essentials"> www.wiley.com/go/strohfeldt/essentials</a> This textbook will provide students of pharmacy, pharmacology, pharmaceutical sciences, and medicinal chemistry with a detailed introduction to inorganic chemistry and the science of metal-based drugs.
