Isoquinolines form one of the largest groups of plant alkaloids and they in clude a number of valuable clinical agents such as codeine, morphine, eme tine and tubocurarine. Research into different aspects of isoquinolines con tinues in profusion, attracting the talents of botanists, chemists, bioche mists, analysts, pharmacists and pharmacologists. Many of these aspects are of an interdisciplinary nature, and in April 1984, The Phytochemical Society of Europe arranged a 3-day symposium on The Chemistry and Bi ology of Isoquinoline Alkaloids in order to provide a forum for scientists of differing disciplines who are united by a common interest in this one class of natural product. Each chapter in this volume is based on a lecture given at this symposium. Attempts have been made to make the aims and objectives, experimental findings and conclusions reached, intelligible to scientists of differing backgrounds. The introductory chapter, which is mainly based on a historical discus sion, stresses that plants containing isoquinolines have proved to be both a boon and a curse to mankind. The Opium Poppy, Papaver somniferum, produces the medicinally used alkaloids morphine, codeine, noscapine and papaverine whilst it also continues to provide drugs of abuse, particularly morphine and its readily prepared O,O-diacetyl derivative, heroin. Numer ous other alkaloids have been isolated from other members of the Papaver acea, and a knowledge of their presence and distribution within the various species has proved a useful adjunct to systematic botanical studies.

The Isoquinoline Alkaloids: A Course in Organic Chemistry is a description of the chemical structures of alkaloids. The book discusses the processes for degradation of isoquinoline alkaloids to recognizable compounds such as oxidation and exhaustive methylation. The associated processes in removing the nitrogen atom are also explained. The commonly used Hofmann process and the interpretation of its result are evaluated in the degradation of alkaloids. The cactus ""pellote"" used by Mexican Indians to induce hallucinatory experiences is examined. The active ingredient is identified as mescaline; its composition is analyzed to contain one primary amino and three methoxyl groups. The different syntheses made to duplicate mescaline are described. The structures of morphine, codeine, and thebain, which are all alkaloids of opium, are also analyzed. Another example of a principal alkaloid found in a plant is emetine found in the root of the ipecac. The pharmacological bases of emetine are isolated and noted as emetamine, cephaeline, psychotrine, and O-methylpsychotrine. The text also traces many other structural relationships within the subgroups of the isoquinoline alkaloids. Chemists, students and professors in organic chemistry, and laboratory technicians whose work is related to pharmacology will find this book informative.

The Isoquinoline Alkaloids: Chemistry and Pharmacology presents an overview of the chemistry, biogenesis, spectroscopy, and pharmacology of the isoquinoline alkaloids. This book examines the significant and interesting aspects of alkaloids. Organized into 32 chapters, this book starts with a discussion of the biogenesis of the isoquinolines and the various pharmacological effects of simple tetrahydroisoquinolines that have stimulant and convulsive properties. This text then explores the infrared absorptions, with emphasis on wavelength and frequency. Other chapters include topics on synthesis, degradation, reactions, absolute configuration, as well as on ultraviolet and nuclear magnetic resonance spectroscopy. This book further explores the various methods available for the preparation of simple tetrahydroisoquinolines, including the Bischler–Napieralski, Pictet–Spengler, and phenolic cyclization, as well as the Friedel–Crafts acylation. The last chapter deals with ancistrocladine, which is the first isoquinoline alkaloid found to possess a methyl group. Biochemists and biophysicists will find this book useful.

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.
