Book Description
Excerpt from The Foundations of Stereo Chemistry: Memoirs by Pasteur, Van't Hoff, Lebel, and Wislicenus Stereo-chemistry, or as it has sometimes been called. Chemistry in space, or Geometrical chemistry, is that branch of chemistry in which the relative position of the atoms in space is taken into consideration. The stereo-chemical theories, like most useful scientific theories, are the result of the necessary expansion of the older views to explain newly discovered facts. The plane structural formulas based upon conceptions of simple atom linking without regard to the actual arrangement of the atoms with respect to one another, were for a time sufficient to meet the requirements of the known facts. While chemists recognized that the atoms of the molecule must have some definite arrangement with respect to one another, it was believed by most chemists that an actual knowledge of this arrangement lay wholly outside of the field of experimental study. The first suggestion leading to the views now held came from Pasteur, (See Pasteur's article here given) in 1860 when he stated that the difference between the active tartaric acids must be due to the asymmetric nonsuperposable character of their molecules. In 1873 Wislicenus, after a thorough study of the active lactic acid derived from meat and the inactive lactic acid from milk, announced that the difference between these two acids must be accounted for by a difference in the arrangement of their atoms in space. The first definite suggestion as to what this arrangement might be was made by van't Hoff in a Dutch pamphlet (here translated) published in September, 1874. Almost at the same time, in November, 1874, LeBel published a paper (here translated) in which he developed, independently, essentially the same views.

Book Description
Unlike some other reproductions of classic texts (1) We have not used OCR(Optical Character Recognition), as this leads to bad quality books with introduced typos. (2) In books where there are images such as portraits, maps, sketches etc We have endeavoured to keep the quality of these images, so they represent accurately the original artefact. Although occasionally there may be certain imperfections with these old texts, we feel they deserve to be made available for future generations to enjoy.

Book Description
Maintaining and enhancing its focus on key issues in the development, regulatory approval and use of stereoisomeric compounds, this edition continues to cover in detail all aspects of chiral drugs from the academic, governmental, industrial and clinical points of view.;Completely rewritten and updated throughout, Drug Stereochemistry: illustrates current indirect chromatographic methods for the resolution of drug enantiomers; treats the rapidly growing area of enantioselective gas chromatography; discusses the latest in HPLC resolution of enantiomeric drugs; uses verapamil as a model to show how stereoselective pharmacokinetics affect pharmacodynamics; and supplies an in-depth study on the effect of stereoselective plasma protein binding.;This edition offers entirely new chapters that: discuss the recent decisions and present position of the US Food and Drug Administration on the development of stereoisomeric drugs; explicate enzymatic synthesis of stereochemically pure drugs; review the toxicological, pharmacokinetic and pharmacodynamic differences found among stereoisomers; elucidate the stereoselective transport of drugs across epithelia; and give a physician's perspective on the questions and problems caused by stereoisomeric drugs in practice as well as the pharmaceutical industry's collective viewpoint based on a national survey.
