This book was released on 2012-01-15 with total page 232 pages. Available in PDF, EPUB and Kindle. Book excerpt: In his thesis, Xiaoyu Sun conducts the first total synthesis of all possible stereoisomers of plakortide E and also confirms the absolute configuration of natural plakortide E. Xiaoyu Sun subsequently converts Plakortide E methyl ester to plakortone B in a biomimetic conversion. Construction and functionalization of cyclic peroxides are notoriously difficult due to the very low O-O bond dissociation energy. Plaktoride E is isolated from the Jamaican marine sponge platorits halichondrioides and contains a five-membered peroxide ring, with oxygen atoms linked to tertiary C4 and C6 centers. The methodology used for synthesizing highly substituted cyclic peroxides is novel and useful, and not only extends the field of Pd-catalyzed reactions, but also provides a convenient synthetic approach for the preparation of the 1,2-dioxolanes series. Plakortide E and plakortone B are bioactive, which means that the synthetic studies on them and their analogs are pivotal in drug discovery.

Download or read book Chemical Synthesis of Nucleoside Analogues written by Pedro Merino and published by John Wiley & Sons. This book was released on 2013-02-12 with total page 859 pages. Available in PDF, EPUB and Kindle. Book excerpt: Compiles current tested and proven approaches to synthesize novel nucleoside analogues Featuring contributions from leading synthetic chemists from around the world, this book brings together and describes tested and proven approaches for the chemical synthesis of common families of nucleoside analogues. Readers will learn to create new nucleoside analogues with desired therapeutic properties by using a variety of methods to chemically modify natural nucleosides, including: Changes to the heterocyclic base Modification of substituents at the sugar ring Replacement of the furanose ring by a different carbo- or heterocyclic ring Introduction of conformational restrictions Synthesis of enantiomers Preparation of hydrolitically stable C-nucleosides Chemical Synthesis of Nucleoside Analogues covers all the major classes of nucleosides, including pronucleotides, C-nucleosides, carbanucleosides, and PNA monomers which have shown great promise as starting points for the synthesis of nucleoside analogues. The book also includes experimental procedures for key reactions related to the synthesis of nucleoside analogues, providing a valuable tool for the preparation of a number of different compounds. Throughout the book, chemical schemes and figures help readers better understand the chemical structures of nucleoside analogues and the methods used to synthesize them. Extensive references serve as a gateway to the growing body of original research studies and reviews in the field. Synthetically modified nucleosides have proven their value as therapeutic drugs, in particular as antiviral and antitumor agents. However, many of these nucleoside analogues have undesirable side effects. With Chemical Synthesis of Nucleoside Analogues as their guide, researchers have a new tool for synthesizing a new generation of nucleoside analogues that can be used as therapeutic drugs with fewer unwanted side effects.
Download or read book Transition States of Biochemical Processes written by R. Gandour and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 625 pages. Available in PDF, EPUB and Kindle. Book excerpt: The transItIOn-state theory has been, from the point of its inception, the most influential principle in the development of our knowledge of reaction mechanisms in solution. It is natural that as the field of biochemical dynamics has achieved new levels of refinement its students have increasingly adopted the concepts and methods of transition-state theory. Indeed, every dynamical problem of biochemistry finds its most elegant and economical statement in the terms of this theory. Enzyme catalytic power, for example, derives from the interaction of enzyme and substrate structures in the transition state, so that an understanding of this power must grow from a knowledge of these structures and interactions. Similarly, transition-state interactions, and the way in which they change as protein structure is altered, constitute the pivotal feature upon which molecular evolution must turn. The complete, coupled dynamical system of the organism, incorporating the transport of matter and energy as well as local chemical processes, will eventually have to yield to a description of its component transition-state structures and their energetic response characteristics, even if the form of the description goes beyond present-day transition-state theory. Finally, the importance of biochemical effectors in medicine and agriculture carries the subject into the world of practical affairs, in the use of transition-state information for the construction of ultra potent biological agents.

Download or read book Structure Correlation written by Hans-Beat Bürgi and published by John Wiley & Sons. This book was released on 2008-07-11 with total page 936 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book leaves the conventional view of chemical structures far behind: it demonstrates how a wealth of valuable, but hitherto unused information can be extracted from available structural data. For example, a single structure determination does not reveal much about a reaction pathway, but a sufficiently large number of comparable structures does. Finding the 'right' question is as important as is the intelligent use of crystallographic databases. Contributions by F.H. Allen, T.L. Blundell, I.D. Brown, H.B. Bürgi, J.D. Dunitz, L. Leiserowitz and others, authoritatively discuss the structure correlation method as well as illustrative results in detail, covering such apparently unrelated subjects as * Bond strength relations in soldis * Crystal structure prediction * Reaction pathways of organic molecules * Ligand/receptor interactions and enzyme mechanisms This book will be useful to the academic and industrial reader alike. It offers both fundamental aspects and diverse applications of what will surely become a powerful branch of structural chemistry.
