Pelletier and you can download with pub, pdf, txt, doc, and more file format with free account. volume 11 of this series presents five timely reviews on current research on alkaloids. chapter 1 by paul l. schiff, jr. is a monumental survey of research that has been carried out over the past decade on the thalictrum alkaloids. forty-six new alkaloids are described from fifteen species of the genus thalictrum, as well as 116 alkaloids of known structure from thirty-six species and subspecies of the genus. the chapter includes discussions of isolation and structure elucidation, analysis, biosynthesis, cell culture, and pharmacology. also featured are inclusive compilations of botanical sources, alkaloids by alkaloid types, and calculated molecular weights of the thalictrum alkaloids. chapter 2 by giovanni appendino provides a fascinating treatment of taxine, a collective name referring to a mixture of diterpenoid alkaloids from the yew tree (genus: taxus). taxine is responsible for the toxic properties of the yew tree that has been documented in historical and fictional literature, from julius caesar to shakespeare, and from agatha christie to t.s. eliot. the chapter treats the history, isolation techniques, structure elucidation, chemistry, and pharmacology of taxine. chapter 3 by mary d. menachery surveys the alkaloids of south american menispermaceae (moonseed family). many different structural types are included in this family. the alkaloid-bearing plants are woody-vines, shrubs, or small trees. several of these species possess potent curare activity. the chemistry as well as pharmacology of these alkaloids is summarized. chapter 4 by russell j. molyneux, robert j. nash, and naoki asano treats the chemistry and biological activity of the calystegines and related nortropane alkaloids. these polyhydroxylated bicyclic alkaloids represent another class of compounds that inhibit glycosidases, producing profound effects in biological systems by disrupting the essential cellular function of glycoprotein processing. chapter 5, a related chapter by robert j. nash, naoki asano, and alison a. watson, reviews polyhydroxylated alkaloids that inhibit glycosidases. topics covered include distribution, ecological significance and toxicity, isolation, synthesis, and biosynthesis.

Description : Read Now Natural Products Chemistry by Raymond Cooper, George Nicola and you can download with pub, pdf, txt, doc, and more file format with free account. notoriously cumbersome to isolate and challenging to synthesize, the path of natural products to viable drugs is an arduous journey. yet compounds isolated from nature may possess fascinating structures, biological profiles and pharmaceutical potential far greater than anything made by man. natural products chemistry: sources, separations and structures presents a practical guide to sourcing, isolating, and discovering new compounds from nature many of which become pharmaceutical drugs. this book emphasizes the challenges and advantages of products acquired from nature, compared to those obtained from combinatorial chemistry. a basic introduction, the book describes the whole cycle from farm to final compound, backed up by case studies drawn from industry and research applications. it broadens the scope of applications and draws upon examples from various sources. natural products chemistry, as taught today, draws its examples mainly from marine chemistry or plant chemistry; however, there is also a fascinating and rich world of fermented (microbial and algal) products leading to complex structures. thus, the book draws upon examples from the microbial world and from insects too. therefore, this is a source of bioactive metabolites, not traditionally available in academic settings, more the mainstay of the pharmaceutical industry. providing a roadmap of the process of collecting a compound from nature, isolating the active ingredient, and determining the chemical structure, this book provides a unique approach to the world of natural products.

Description : Read Now Handbook Of Naturally Occurring Compounds by T.K. Devon and you can download with pub, pdf, txt, doc, and more file format with free account. handbook of naturally occurring compounds, volume ii: terpenes is a handbook of naturally occurring compounds to which structures have been assigned, with particular reference to terpenes. each structure is stored in the handbook with its name, molecular formula, molecular weight, optical rotation, melting point, literature reference, and classification number. comprised of 10 chapters, this volume begins with an overview of terpenes and their classification schemes, followed by terpenoid classes and their structural/biogenetic categories as well as skeletons: monoterpenes, sesquiterpenes, diterpenes, sesterterpenes, triterpenes, steroids, carotenoids, and polyprenoids. miscellaneous compounds of terpenoid origin are also considered, including the ionones and fraxinellone. this final category for miscellaneous compounds of terpenoid origin arises through the somewhat frequent occurrence of oxidative degradation in terpenoid biosynthesis. in general these compounds have degraded structures such that there exists some ambiguity as to their precise biosynthetic precursors. each individual compound possesses a compound sequence number which, in combination with the classification code number, supplies a unique address for that compound. this book should be a valuable resource for chemists as well as students and researchers of chemistry.

Description : Read Now Stereochemistry Of Radical Reactions by Dennis P. Curran, Ned A. Porter, Bernd Giese and you can download with pub, pdf, txt, doc, and more file format with free account. as little as a decade ago, radicals were regarded as interesting reactive intermediates with little synthetic use. however, recent results show that radicals have an enormous potential for applications in stereoselective reactions - it's all a matter of knowing what method to use and how to apply it. three world experts in the field have combined their expertise and present the concepts to understand and even to predict the course of stereoselective radical reactions. in addition, guidelines are established which will enable the readers to plan and carry out their own stereoselective syntheses with radicals. a comprehensive list of references provides an easy access to the primary literature. the stereochemistry of radical reactions is a highly topical introduction to this burgeoning field of research. both advanced students and researchers active in the field will welcome this book as a source of concepts and ideas.
