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
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
Transformations using enzymes have been extensively investigated in the last two decades and the results promise great potential for this growing field, especially in the area of synthetic organic chemistry mainly due to of its many advantages. Accordingly, this book has attempted to bring out the advantages of using enzymes involving complex underivatized and unprotected substrates in non-polar media under homogenous and heterogeneous reaction conditions. Merits and demerits of using enzymes in terms of yields and selectivity/specificity are presented without any prejudice. Almost all the reactions dealt with are from the author’s laboratory comprising diverse substrates, and the catalysis involves two important hydrolyzing enzymes, extensively examined for the reverse reactions. Thus, esterification involving lipses and glycosylation involving glycosidases were investigated with respect to various strategies like optimization of reaction conditions, response surface methodology and kinetics, carrying out reactions under solvent, non-solvent and super critical carbon dioxide conditions. In short, the work presented is to ensure the comprehension of the problems faced by the researchers in this area so as to work out further efficient strategies for carrying out enzymatic transformations in the laboratory successfully with better yields and specificity.

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
Recent developments in genetic engineering and protein chemistry are bringing ever more powerful means of analysis to bear on the study of enzyme structure. This volume reviews the most important types of industrial enzymes. In a balanced manner it covers three interrelated aspects of paramount importance for enzyme performance: three-dimensional protein structure, physicochemical and catalytic properties, and the range of both classical and novel applications.

Book Description
Die Suche nach Medikamenten mit neuen oder verbesserten Eigenschaften hat das Interesse am pharmazeutischen Potenzial von Kohlenhydraten enorm verstärkt. Dies gilt insbesondere für die Entwicklung von Antibiotika, Impfstoffen und Anti-Krebs-Mitteln. Carbohydrate-based Drug Discovery stellt mit mehr als 50 Beiträgen der weltweit führenden Experten die neuesten Entwicklungen in der Kohlenhydrat- und Biochemie vor. Dabei liegt der Schwerpunkt der Darstellung auf der pharmazeutischen Anwendung. In jüngster Zeit sind wirksame, auf Kohlenhydraten basierende Medikamente gegen HIV, Grippe, Epilepsie, Diabetes und Krebs auf den Markt gekommen bzw. werden in Studien klinisch erprobt. Doch das gesamte Potenzial dieser Substanzklasse kann man bislang wohl nur erahnen. Die pharmazeutische Industrie investiert bereits große Summen in die Forschung und Entwicklung. So kommt dieses Handbuch genau zur richtigen Zeit. Umfassend und kompetent behandelt es den gesamten Bereich der Kohlenhydratchemie. Es führt ein in die chemische Synthese, in Biosynthese und Metabolismus und informiert über die Analyse und die zellulären Funktionen von Kohlenhydraten. Einen weiteren Schwerpunkt bildet die Entwicklung von Medikamenten auf Kohlenhydrat-Basis, wie z.B. synthetischer Impfstoffe oder Thrombosemittel auf Basis synthetischer Oligosaccharide. Erschlossen wird das mit einem umfangreichen bibliographischen Anhang versehene Werk durch einen thematischen Index. Sein Herausgeber, Chi-Huey Wong, hat bereits mehrere internationale Preise für sein wissenschaftliches Werk erhalten, darunter den "Presidential Award" und den "Presidential Young Investigator Award".

Book Description
Chemistry and chemical engineering have changed significantly in the last decade. They have broadened their scopeâ€"into biology, nanotechnology, materials science, computation, and advanced methods of process systems engineering and controlâ€"so much that the programs in most chemistry and chemical engineering departments now barely resemble the classical notion of chemistry. Beyond the Molecular Frontier brings together research, discovery, and invention across the entire spectrum of the chemical sciencesâ€"from fundamental, molecular-level chemistry to large-scale chemical processing technology. This reflects the way the field has evolved, the synergy at universities between research and education in chemistry and chemical engineering, and the way chemists and chemical engineers work together in industry. The astonishing developments in science and engineering during the 20th century have made it possible to dream of new goals that might previously have been considered unthinkable. This book identifies the key opportunities and challenges for the chemical sciences, from basic research to societal needs and from terrorism defense to environmental protection, and it looks at the ways in which chemists and chemical engineers can work together to contribute to an improved future.
