Internet has emerged as a powerful medium for storage, retrieval and dissemination of information on the web and the user of the information growing rapidly. Information Communication ant Technology has changed the concept of library, where the print and paper media are the main components to the new system called digital library.Digital libraries can be viewed as a new form of information institution or as an extension of the services of libraries currently provided. Multimedia is one of the components ofthe information technology that is being used in digital libraries in the handling and dissemination of information. The librarian needs to be aware of the many characteristicsof the multitude of communication forms available. This book organizes and investigates the prevalent information communication technologies and multimedia for themanagement of digital library is an effort to assist the professionals in becoming more knowledgeable about them.…

Taschenbuch. Zustand: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Indole based alkaloids are well known in the literature for their diverse biological properties. Polysubstituted optically active tetrahydro-beta-carboline derivatives functionalized on C-1 position are the common structural motif in most of the indole based alkaloids as well as highly marketed drugs. The stereoselective Pictet-Spengler reaction is one of the currently most important synthetic techniques used for the preparation of these privileged tetrahydro-beta-carboline scaffolds. To date there are numerous research reports that have been published on the synthesis of the tetrahydro-beta-carboline scaffold both on solid phase as well as in solution phase. Moreover rapid growth has been observed for the enantioselective synthesis of tetrahydro-beta-carboline scaffold using chiral organocatalysts. In this book, efforts have been taken to shed light on the latest information available on different strategies to synthesize tetrahydro-beta-carboline both on solid phase and in solution phase during the last 20 years. 84 pp. Englisch.…

Taschenbuch. Zustand: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Heterocyclic compounds with nitrogen atom play a key role in the normal life cycle of a cell. Pyrazolopyrimidine is a privileged class of nitrogen containing fused heterocyclic compound contributing to a major portion of all lead molecules in medicinal chemistry. The thumbprint of pyrazolopyrimidine as a pharmacophore is always noticeable due to its analogy with the adenine base in DNA. Pyrazolopyrimidines are divided into five types [I, II, III, IV, V] based on the mechanism of action on the specific target conferring a wide scope of research which has accelerated the interest of researchers to investigate its biological profile. In 1956, the anti-cancer activity of pyrazolopyrimidine was evaluated for the first time with appreciable activity. Since then, medicinal chemists centered their work on various methods of synthesis and evaluating the biological profile of pyrazolopyrimidine isomers. This book consists of novel methodologies followed to synthesize pyrazolopyrimidine isomers along with a note on their anticancer activity. 152 pp. Englisch.…
