Book Description
Piperidine-Based Drug Discovery outlines the complexities of Piperidine scaffold use in drug discovery, including derivative chemistry, structural properties, methods of synthesis and practical implementations. Piperidine scaffolds are the cornerstones of over 70 commercialized drugs (including multiple blockbusters). Designed as a guide for both experts and students working in this and related areas, it is hoped that this volume will encourage and inspire the continued design and development of novel pharmaceuticals based on Piperidine and its derivatives. Heterocyclic compounds are of central importance to medicinal chemistry, as demonstrated by the high percentage of marketable drugs that feature heterocyclic fragments in their structures. As starting points for drug discovery they offer a broad range of attractive properties, and a detailed understanding of the particular characteristics of each is of great benefit to researchers. The most commonly used heterocycle among US FDA approved pharmaceuticals, Piperidine is an extremely important building block in the synthesis of medicinal agents. This heterocycle and its derivatives exhibit a number of important functionalities and have been employed variously as CNS modulators, antiaggregants, anticoagulants, antihistamines, anti-cancer drugs and analgesics. - Explores this extremely important heterocycle to a high level of detail - Describes synthesis methods for 70 current drugs based on Piperidine scaffolds - Gives drug designers all the key knowledge required to develop new drugs utilizing Piperidine - Provides pharmacologists a solid overview of the chemical background of existing Piperidine-based drugs

Book Description
Piperidine, one of the simplest heterocyclic systems, is found in nature as part of several alkaloid compounds. Both natural and especially unnatural piperidine derivatives present interesting pharmacological properties. From a structural viewpoint, the conformation of piperidine has been the subject of one of the fiercest controversies in structural organic chemistry in the last few years. As a result of the combined use of several spectroscopic techniques, the conformational behavior of most types of piperidine-related compounds has been clarified. Some piperidine derivatives, namely, N-acylpiperidine, &agr;-cyanopiperidines and piperidones are extremely useful and versatile intermediates in organic synthesis. The present book offers an updated and integrated view of all these topics. The aim of the book is twofold. Firstly, to reveal to the reader the combined use of different spectroscopic data, to facilitate an insight into the structure and conformational properties of any new piperidine derivative. Secondly, to establish a consistent link between conformation and reactivity for a variety of piperidine derivatives. Such a bridge is a key step for stereocontrol when dealing with the application of piperidine derivatives as synthetic intermediates. The book is conceived so that most of the information comes from visual inspection of the very abundant graphic material. An exhaustive subject index of more than 450 entries is also included.

Book Description
The alkaloids were of great importance to mankind for centuries, long before they were recognized as a chemical class. The influence they have had on literature is hinted at by some of the quotations I have used as chapter headings. Their in fluence on folklore and on medicine has been even greater. The scientific study of alkaloids may be said to have begun with the isolation of morphine by SERTURNER in 1804. Since that time they have remained of great interest to chemists, and now in any month there appear dozens of publications dealing with the isolation of new alkaloids or the determination of the structures of previously known ones. The area of alkaloid biochemistry, in comparison, has received little attention, and today is much less developed. There is a certain amount of personal arbitrariness in defining "biochemistry", as there is in defining "alkaloid", and this arbitrariness is doubtless compounded by the combination. Nevertheless, it seems to me that in any consideration of the bio chemistry of a group of compounds three aspects are always worthy of attention pathways of biosynthesis, function or activity, and pathways of degradation. For the alkaloids, treatment of these three aspects is necessarily lopsided. Much has been learned about routes of biosynthesis, but information on the other aspects is very scanty. It would be possible to enter into some speculation regarding the biosyn thesis of all the more than 1,000 known alkaloids.

Book Description
Noting a marked lack of comprehensiveness and/or contemporaneity among typical reference works on chemical etymology, as well as a somewhat spotty coverage of chemical terms and their etymology in comprehensive dictionaries and textbooks the author decided to write an up-to-date desk reference on chemical etymology which would satisfy the needs of casual readers as well as those of more demanding users of etymological lore. Characteristic user-friendly features of the present work include avoidance of cumbersome abbreviations, avoidance of entries in foreign alphabets, and a broad coverage of all chemical disciplines including mineralogy. Biological, medical, geological, physical and mathematical terms are only considered where they appear of interest to mainstream chemists.This book does not provide definitions of terms (unless required in the etymological context) nor guidance as to the timeliness of different nomenclature systems. The typical user will from the outset be well aware of the exact meaning of the terms he or she focuses on and only require the etymological background to be used. Examples of sources which have been drawn upon in the preparation of this book, apart from the extremely useful Internet resource Google, are listed, but an exhausting enumeration would be tiresome and impractical..* an up-to-date desk reference on chemical etymology* characteristic user-friendly features* broad coverage of all chemical disciplines

Book Description
At the request of the Department of Defense and the Environmental Protection Agency, the National Research Council has reviewed the relevant scientific literature compiled by an expert panel and established Acute Exposure Guideline Levels (AEGLs) for several chemicals. AEGLs represent exposure levels below which adverse health effects are not likely to occur and are useful in responding to emergencies, such as accidental or intentional chemical releases in community, workplace, transportation, and military settings, and for the remediation of contaminated sites. Three AEGLs are approved for each chemical, representing exposure levels that result in: 1) notable but reversible discomfort; 2) long-lasting health effects; and 3) life-threatening health impacts. Acute Exposure Guideline Levels for Selected Airborne Chemicals: Volume 13 includes AEGLs for boron trifluoride, bromoacetone, chloroacetone, hexafluoroacetone, perchloryl fluoride, piperidine, propargyl alcohol, trimethoxysilane and tetramethoxysilane, and trimethylbenzenes.
