Book Description
This third edition is a comprehensive and extended study about the best known approaches for preparing the main types of glycosides, covering the classic and more recent glycosylation reactions used for preparing simple and challenging glycosides currently used as potent antiviral and antineoplastic drugs, or fluorogenic substrates used for enzymatic detection in cell biology. Besides, this new edition provides more examples of the glycosidic methodologies followed for preparing complex glycoconjugates such as glycoproteins and glycosphingolipids and gangliosides used as adjuvants or as synthetic vaccines candidates. Also, additional mechanistic evidence is presented for better understanding of the glycosylation reaction, trying to identify the variables mainly depending on protecting and leaving groups, as well as catalyst and reaction condition which altogether directs the anomeric stereo control. A chapter on the glycoside hydrolysis is included in view of the increasing interest in the use of biomass as a natural and renewable source for obtaining important intermediates or products used in food or valuable materials. The author includes information in the characterization of glycosides section with the aim of giving additional tools for the structural assignment through NMR, X-Ray and mass spectra techniques.

Book Description
This book contains the best known approaches for preparing the main types of glycosides in a short and comprehensive study. It also includes synthetic pathways of challenging glycosides known as antiviral or antineoplasic drugs, or synthetic substrates used for enzymatic detection including those used as substrates for detection of gene markers in plant biotechnology. Special attention is made on the structural characterization, providing the basic tools for the structural assignment through NMR, X-Ray and mass spectra techniques. Some of the chapters cover strategies for preparation of antiviral and antineoplasic drugs included in a drug design course.

Book Description
Carbohydrate Chemistry in the Total Synthesis of Naturally Occurring Glycosides Revolutionize your manufacturing processes and more with this groundbreaking introduction Carbohydrates and complex glycosides are important classes of molecules. The ubiquitous glycosides are extremely diverse in structure and functions, and many of them are of pharmacological significance. Purification of a homogeneous glycoside from the nature sources, especially in an appreciable amount, is always difficult. Chemical synthesis provides a feasible access to the homogenous glycosides and their congeners. Carbohydrate Chemistry in the Total Synthesis of Naturally Occurring Glycosides presents about 10 families of naturally occurring glycoside natural products, including about 150 molecules that organic chemists have devoted a lot of effort toward their synthesis. In each example, the background of each natural glycoside, including its natural resources, its isolation process and its bioactivities have been described; the total synthesis of the natural glycoside is presented with special emphasis on the glycosylation reaction, the strategy on saccharides assembly, the protecting group manipulation, and the method for the synthesis of the rare saccharide units. Readers can clearly see the progress of total synthesis of naturally occurring glycosides, from early to current arts, from simple to complex molecules, and from tedious strategy to highly efficient and economical methodologies in this book. It will highly benefit the further developments in the total synthesis of naturally occurring glycosides and synthetic carbohydrate chemistry. Carbohydrate Chemistry in the Total Synthesis of Naturally Occurring Glycosides is ideal for Organic Chemists, Biochemists, Pharmaceutical and Medicinal Chemists, Natural Products Chemists, and Pharmaceutical Industry

Book Description
This reference book originates from the interdisciplinary research cooperation between academia and industry. In three distinct parts, latest results from basic research on stable enzymes are explained and brought into context with possible industrial applications. Downstream processing technology as well as biocatalytic and biotechnological production processes from global players display the enormous potential of biocatalysts. Application of "extreme" reaction conditions (i.e. unconventional, such as high temperature, pressure, and pH value) - biocatalysts are normally used within a well defined process window - leads to novel synthetic effects. Both novel enzyme systems and the synthetic routes in which they can be applied are made accessible to the reader. In addition, the complementary innovative process technology under unconventional conditions is highlighted by latest examples from biotech industry.

Book Description
Resin glycosides are part of a very extensive family of secondary metabolites known as glycolipids or lipo-oligosaccharides and are constituents of complex resins (glycoresins) (1) unique to the morning glory family, Convolvulaceae (2). These active principles are responsible for the drastic purgative action of all the important Convolvulaceous species used in traditional medicine throughout the world since ancient times. Several commercial purgative crude drugs can be prepared from the roots of different species of Mexican morning glories. Their incorporation as therapeutic agents in Europe is an outstanding example of the assimilation of botanical drugs from the Americas as substitutes for traditional Old World remedies (3). Even though phytochemical investigations on the constituents of these drugs were initiated during the second half of the nineteenth century, the structure of their active ingredients still remains poorly known for some examples of these purgative roots. During the last two decades, the higher resolution c- abilities of modern analytical isolation techniques used in conjunction with pow- ful spectroscopic methods have facilitated the elucidation of the active principles of these relevant herbal products. This chapter describes the ethnobotanical information associated with the p- gative morning glory species and how traditional usages were instrumental in plant selection for chemical studies. The advantages and limitations of available analy- cal techniques for the isolation, puri?cation, and structure characterization of the individual constituents of these complex glycoconjugates are also discussed.
