This book was released on 2012-12-06 with total page 808 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of antibiotics in the treatment by antibacterial and antifungal chemo therapy, has become standard practice since the end of World War Two and has had an enormous impact on healthcare throughout the world. Compounds belonging to this class have also reached an important place in the medical treatment of human cancer. Although, the discovery of most of these agents came from more or less sophisticated screening programs of soil microrganisms, many of the important antibiotics used today in clinical practice are derived from the original biosynthetic products by the application of often novel and generally elaborated chemical synthetic methodologies. In fact the antibiotics have represented (and still represent) for a generation of organic chemists an endless source of molecular structures whose varied assemblage of carbon atom backbones and chemical functions was beyond any possibility of imagination. Perhaps a similar repertoire of chemotypes was formerly offered by the natural products, namely the alkaloids, the terpenes, the vitamins and hormones as well as the pigments of the animal and plant kingdoms, albeit the chemical arrange ments of the antibiotic molecules appeared much more surprising and diverse to the admiring eyes of cultivated organic chemists. The idea of this book, certainly a landmark in the field, came during the Symposium of EUCHEM on Chemical Synthesis of Antibiotics, that was held at Aussois in Savoy, France (May 2-6, 1988), the initiative being taken by Gabor Lukacs to whom Masaji Ohno readily associated as a co-editor.

Book excerpt: There are only very few chemical classes of antibiotics in medical use, and these have originated over a span of more than 60 years of research. Almost half a century ago, the first member of the macrolides, erythromycin, was introduced as a treatment option for bacterial infections. Erythromycin is a very complex fermentation product obtained from the soil bacterium Saccharopolyspora ery thraea (originally named Streptomyces erythreus). The success of erythromycin, based on its efficacy and tolerability, stimulated researchers throughout the world to undertake intense efforts to understand the biology and chemistry of macrolides and to use this experience to improve the properties of this compound class. The second generation of macrolides, based on chemical modifications of erythromy cin, is currently being in broad use, especially for treatment of respiratory tract infections. We presently foresee the introduction of a new generation of macro lides, i. e. the ketolides, which have the potential to overcome rising resistance problems. This monograph is intended to give the interested reader an overview on "macrolide experience", covering important areas from basic research to clinical use. Starting from a historic overview, the essential basic parameters - efficacy, pharmacokinetics, pharmacodynamics, and pharmacology - are highlighted in order to introduce the reader to the rationale for clinical use of macrolides. The following group of chapters cover the complex chemistry of the macro lactone structures, giving historic background, basic structure-activity relation ships of various derivatization strategies, and perspectives for future discovery of new semisynthetic macrolide antibiotics.

Available in PDF, EPUB and Kindle. Book excerpt: Provides both fundamentals and new and emerging applications Advanced Drug Delivery brings readers fully up to date with the state of the science, presenting the basics, formulation strategies, and therapeutic applications of advanced drug delivery. The book demonstrates how core concepts of pharmaceutical sciences, chemistry, and molecular biology can be combined and applied in order to spark novel ideas to design and develop advanced drug delivery systems for the treatment of a broad range of human diseases. Advanced Drug Delivery features contributions from an international team of pharmaceutical scientists. Chapters reflect a thorough review and analysis of the literature as well as the authors' firsthand experience developing drug delivery systems. The book is divided into four parts: Part I, Introduction and Basics of Advanced Drug Delivery, explores physiological barriers, stability, transporters, and biomaterials in drug delivery Part II, Strategies for Advanced Drug Delivery, offers tested and proven strategies for advanced delivery of both small molecules and macromolecules Part III, Translational Research of Advanced Drug Delivery, focuses on regulatory considerations and translational applications of advanced drug delivery systems for the treatment of cardiovascular diseases, cancer, sexually transmitted diseases, ophthalmic diseases, and brain diseases Part IV, Future Applications of Advanced Drug Delivery in Emerging Research Areas, examines stem cell research, cell-based therapeutics, tissue engineering, and molecular imaging Each chapter provides objectives and assessment questions to help readers grasp key concepts and assess their knowledge as they progress through the book. Advanced Drug Delivery is recommended for graduates and upper-level undergraduates in the pharmaceutical sciences who need a solid foundation in the basics. It is also recommended for pharmaceutical professionals who want to take advantage of new and emerging applications in advanced drug delivery systems.
