Available in PDF, EPUB and Kindle. Book excerpt: Medicinal Chemistry, Volume 19: Quantitative Structure-Activity Relationships of Drugs is a critical review of the applications of various quantitative structure-activity relationship (QSAR) methodologies in different drug therapeutic areas and discusses the results in terms of their contribution to medicinal chemistry. After briefly describing the developments in QSAR research, this 12-chapter volume goes on discussing the contributions of QSAR methodology in elucidating drug action and rational development of drugs against bacterial, fungal, viral, and other parasitic infections of man. Other chapters explore the mode of action and QSAR of antitumor, cardiovascular, antiallergic, antiulcer, antiarthritic, and nonsteroidal antiinflammatory drugs (NSAID) agents. The discussion then shifts to the pharmacologic effects and QSAR analysis of central nervous system agents, steroids, and other hormones. A chapter examines the major chemicals affecting insects and mites, with particular emphasis on the parameters of binding correlation and reactivity for insect and mite enzymes. The concluding chapters cover the limitations of the QSAR approach in the quantitative treatment of drug absorption, distribution, and metabolism. This volume is of great value to medicinal chemists, scientists, and researchers.

Download or read book 3D QSAR in Drug Design written by Hugo Kubinyi and published by Springer Science & Business Media. This book was released on 2006-04-11 with total page 413 pages. Available in PDF, EPUB and Kindle. Book excerpt: Significant progress has been made in the study of three-dimensional quantitative structure-activity relationships (3D QSAR) since the first publication by Richard Cramer in 1988 and the first volume in the series. 3D QSAR in Drug Design. Theory, Methods and Applications, published in 1993. The aim of that early book was to contribute to the understanding and the further application of CoMFA and related approaches and to facilitate the appropriate use of these methods. Since then, hundreds of papers have appeared using the quickly developing techniques of both 3D QSAR and computational sciences to study a broad variety of biological problems. Again the editor(s) felt that the time had come to solicit reviews on published and new viewpoints to document the state of the art of 3D QSAR in its broadest definition and to provide visions of where new techniques will emerge or new appli- tions may be found. The intention is not only to highlight new ideas but also to show the shortcomings, inaccuracies, and abuses of the methods. We hope this book will enable others to separate trivial from visionary approaches and me-too methodology from in- vative techniques. These concerns guided our choice of contributors. To our delight, our call for papers elicited a great many manuscripts.

Download or read book A Primer on QSAR QSPR Modeling written by Kunal Roy and published by Springer. This book was released on 2015-04-11 with total page 129 pages. Available in PDF, EPUB and Kindle. Book excerpt: This brief goes back to basics and describes the Quantitative structure-activity/property relationships (QSARs/QSPRs) that represent predictive models derived from the application of statistical tools correlating biological activity (including therapeutic and toxic) and properties of chemicals (drugs/toxicants/environmental pollutants) with descriptors representative of molecular structure and/or properties. It explains how the sub-discipline of Cheminformatics is used for many applications such as risk assessment, toxicity prediction, property prediction and regulatory decisions apart from drug discovery and lead optimization. The authors also present, in basic terms, how QSARs and related chemometric tools are extensively involved in medicinal chemistry, environmental chemistry and agricultural chemistry for ranking of potential compounds and prioritizing experiments. At present, there is no standard or introductory publication available that introduces this important topic to students of chemistry and pharmacy. With this in mind, the authors have carefully compiled this brief in order to provide a thorough and painless introduction to the fundamental concepts of QSAR/QSPR modelling. The brief is aimed at novice readers.
