Download or read book Drug Discovery and Design Using Natural Products written by Jorddy Neves Cruz and published by Springer Nature. This book was released on 2023-08-28 with total page 541 pages. Available in PDF, EPUB and Kindle. Book excerpt: Historically, natural products have great relevance for the development of new drugs. Natural molecules, in addition to directly providing new compounds with different therapeutic functions have provided scaffolds and a great diversity of structures that serve as inspiration for the design and discovery of new drugs. The great structural complexity and the significant number of natural compounds that can be obtained and their advantages also present some historical problems that need to be overcome. Issues such as difficulty in isolation, difficulty in synthesizing compounds found in nature in the laboratory, screening to evaluate the biological properties of these compounds, and structural optimization to enhance the pharmacological properties of biomolecules; are some of the main difficulties encountered in research with natural products and in the design/discovery of new medicines. Therefore, this book addresses the great scientific advances that provide practical solutions to using natural products to develop new drugs. We address topics related to the genesis of research projects that use natural products to design new drugs. We address the discovery of new species, initial processes for identification and extraction of compounds, isolation and identification of these structures, techniques, and advances in vitro and in vivo methods that support the discovery of new natural drugs, synthesis of new compounds from natural molecules, in silico optimization processes of potentially promising compounds.

This book was released on 2002-12-11 with total page 314 pages. Available in PDF, EPUB and Kindle. Book excerpt: Research in the pharmaceutical industry today is in many respects quite different from what it used to be only fifteen years ago. There have been dramatic changes in approaches for identifying new chemical entities with a desired biological activity. While chemical modification of existing leads was the most important approach in the 1970s and 1980s, high-throughput screening and structure-based design are now major players among a multitude of methods used in drug discov ery. Quite often, companies favor one of these relatively new approaches over the other, e.g., screening over rational design, or vice versa, but we believe that an intelligent and concerted use of several or all methods currently available to drug discovery will be more successful in the medium term. What has changed most significantly in the past few years is the time available for identifying new chemical entities. Because of the high costs of drug discovery projects, pressure for maximum success in the shortest possible time is higher than ever. In addition, the multidisciplinary character of the field is much more pronounced today than it used to be. As a consequence, researchers and project managers in the pharmaceutical industry should have a solid knowledge of the more important methods available to drug discovery, because it is the rapidly and intelligently combined use of these which will determine the success or failure of preclinical projects.

Download or read book Organic Syntheses Based on Name Reactions and Unnamed Reactions written by Alfred Hassner and published by Elsevier. This book was released on 2013-10-22 with total page 462 pages. Available in PDF, EPUB and Kindle. Book excerpt: Synthetically useful organic reactions or reagents are often referred to by the name of the discoverer(s) or developer(s). Older name reactions are described in text books, but more recently developed synthetically useful reactions that may have been associated occasionally with a name are not always well known. For neither of the above are experimental procedures or references easy to find. In this monograph approximately 500 name reactions are included, of which over 200 represent newer name reactions and modern reagents. Each of these reactions are extremely useful for the contemporary organic chemistry researcher in industry or academic institutions. This book provides the information in an easily accessible form. In addition to seminal references and reviews, one or more examples for each name reaction are provided and a complete typical experimental procedure is included, to enable the student or researcher to immediately evaluate reaction conditions. Besides an alphabetical listing of reactions and reagents, cross references permit the organic practitioner to find those name reactions or reagents that enable specific transformations, such as, conversion of amines to nitriles, stereoselective reduction, fluoroalkylation, phenol alkynylation, asymmetric syntheses, allylic alkylation, nucleoside synthesis, cyclopentanation, hydrozirconation, to name a few. Emphasis has been placed on stereoselective and regioselective transformations as well as on enantioselective processes. The listing of reactions and reagents is supported by four indexes.
Download or read book New Horizons of Process Chemistry written by Kiyoshi Tomioka and published by Springer. This book was released on 2017-03-17 with total page 285 pages. Available in PDF, EPUB and Kindle. Book excerpt: The methodologies and technologies adaptable to process chemistry are the focus of this unique book, as new catalysts, reactions, and methods for the synthesis of functional materials are dealt with in depth for the first time. Those materials take in pharmaceuticals, agrochemicals, functional materials, chemical raw materials, and other substances in the field of process chemistry including green chemistry. Process chemistry underpins the competitiveness of chemical and pharmaceutical industries, but its stagnation is estimated to cause industrial depression and excessive loss. For that reason, chemists focus on process chemistry consistently so that the development of novel and efficient new reactions and technologies provides an essential stimulus. In addition, this volume describes the important development of selected new synthetic devices for process development and the process design for a larger scale, thus furnishing a valuable source for all who are engaged in process chemistry.
Download or read book Templated Organic Synthesis written by François Diederich and published by Wiley-VCH. This book was released on 2000 with total page 438 pages. Available in PDF, EPUB and Kindle. Book excerpt: Templated Organic Synthesis Edited by F. Diederich and P. J. Stang Located at the borderline of supramolecular and organic chemistry, template-controlled reactions allow the synthesis of complex molecules which would hardly be achievable through classical methods. This handbook offers authorative information on how noncovalent and covalent templates can be effectively applied to control reaction rates as well as regio- and stereo-selectivity. From the concepts of template control such as molecular imprinting, self-replication, and reversible tether-directed remote functionalization, the reader is led to template-based ring-closing reactions, oligomerizations, and multiple functionalizations and their application in the synthesis of supramolecular scaffolds and natural products. The editors and authors, all internationally recognized experts in their area, succeeded in presenting the manifold aspects of template-controlled synthesis in a didactic way, making this methodology accessible to a broad readership of organic synthetic chemists. Well-selected, reliable key experimental protocols and an up-to-date reference list underline the practical approach of this valuable handbook. Being the first book of its kind, it will serve as a pacemaker and stimulate future research.
