Ernst and Lloyd M. Jackman

Solving Problems with NMR Spectroscopy, Second Edition, is a fully updated and revised version of the best-selling book. This new edition still clearly presents the basic principles and applications of NMR spectroscopy with only as much math as is necessary. It shows how to solve chemical structures with NMR by giving many new, clear examples for readers to understand and try, with new solutions provided in the text. It also explains new developments and concepts in NMR spectroscopy, including sensitivity problems (hardware and software solutions) and an extension of the multidimensional coverage to 3D NMR. The book also includes a series of applications showing how NMR is used in real life to solve advanced problems beyond simple small-molecule chemical analysis. This new text enables organic chemistry students to choose the most appropriate NMR techniques to solve specific structures. The problems provided by the authors help readers understand the discussion more clearly and the solution and interpretation of spectra help readers become proficient in the application of important, modern 1D, 2D, and 3D NMR techniques to structural studies. Explains and presents the most important NMR techniques used for structural determinations Offers a unique problem-solving approach for readers to understand how to solve structure problems Uses questions and problems, including discussions of their solutions and interpretations, to help readers understand the fundamentals and applications of NMR Avoids use of extensive mathematical formulas and clearly explains how to implement NMR structure analysis Foreword by Nobel Prize winner Richard R.

Drug Design and Discovery in Alzheimer's Disease includes expert reviews of recent developments in Alzheimer's disease (AD) and neurodegenerative disease research. Originally published by Bentham as Frontiers in Drug Design and Discovery, Volume 6and now distributed by Elsevier, this compilation of the sixteen articles, written by leading global researchers, focuses on key developments in the understanding of the disease at molecular levels, identification and validation of molecular targets, as well as innovative approaches towards drug discovery, development, and delivery. Beginning with an overview of AD pharmacotherapy and existing blockbuster drugs, the reviews cover the potential of both natural and synthetic small molecules; the role of cholinesterases in the on-set and progression of AD and their inhibition; the role of beta-site APP clearing enzyme-1 (BACE-1) in the production of ?-amyloid proteins, one of the key reasons of the progression of AD; and other targets identified for AD drug discovery.

The inhibition of angiogenesis is an effective mechanism of slowing down tumor growth and malignancies. The process of induction or pro-angiogenesis is highly desirable for the treatment of cardiovascular diseases, wound healing disorders, and more. Efforts to understand the molecular basis, both for inhibition and induction, have yielded fascinating results.

Originally published by Bentham and now distributed by Elsevier, Anti-Angiogenesis Drug Discovery and Development, Volume 2 is an compilation of well-written reviews on various aspects of the anti-angiogenesis process. These reviews have been contributed by leading practitioners in drug discovery science and highlight the major developments in this exciting field in the last two decades. These reader-friendly chapters cover topics of great scientific importance, many of which are considered significant medical breakthroughs, making this book excellent reading both for the novice as well as for expert medicinal chemists and clinicians.
