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 specific topic, “Isoquinolines And Beta-Carbolines As Neurotoxins And Neuroprotectants – New Perspectives In Parkinson`S Disease Therapy,” was chosen in light of accumulating neurobiological evidence indicating that, in addition to exogenous neurotoxins (e.g., 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine [MPTP]), endogenous compounds may play an important role in the most common neurodegenerative disorders (e.g., Parkinson`s disease). Two groups of amine related compounds, which appeared chemically like MPTP, were detected in human brain and cerebrospinal fluid (CSF): ß-carbolines (BCs) and tetrahydroisoquinolines (TIQs). These are heterocyclic compounds formed endogenously from phenylalanine/tyrosine (TIQs) and tryptophan, tryptamine, and 5-hydroxytryptamine (BCs), respectively and exert a wide spectrum of psychopharmacological and behavioral effects. The TIQs and BCs may bind to their own high affinity sites on neuronal membranes associated with or located close to the receptors of neurotransmitters. Research on TIQs and BCs is stimulated also by their possible role in pathological conditions, especially parkinsonism and alcoholism. Recently, clinical interest has been spurred by their role as neuroprotective, and even neurorestorative, anticonvulsant and antiaddictive, substances. In this book we are going to summarize, for the first time, the results from behavioral, neurochemical and molecular experiments, which demonstrate a wide spectrum of TIQs and BCs effects - from their rather mild neurotoxic actions to the important neuroprotective and antiaddictive properties. Additionally, the recent results of experimental studies in vivo have allowed a much better understanding and simultaneous comparison of the neurochemical and molecular mechanisms underlying the neuroprotective and neurotoxic actions of endogenous TIQs and BCs and have pointed to the possibility of their therapeutic applications in neurodegenerative diseases such as Parkinson's disease.

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.

Molecular toxicology is on the way to setting a new standard in toxic risk assessment, with the powerful help of concepts and methods developed in the fields of molecular and cellular biology. The methods of molecular toxicology are endowed with qualities not always secured in more traditional approaches to toxicity assessment. These methods are easily standardized, reliable, reproducible and require only tiny amounts of the xenobiotic. They are much simpler, faster and less costly than current tests on animals and can be implemented with modest laboratory resources. This volume of Advances in Molecular Toxicology represents a collection of invited papers presented at the First European Workshop on Molecular Toxicology in Sophia Antipolis, France, The book covers 8 selected topics in molecular toxicology. The first two are devoted to ''physics'', dealing respectively with advanced instrumentation enabling location and quantification of xenobiotics in cells and organs with ultimate precision, and computer-assisted assessment of risk (QSAR). A comprehensive and up-to-date survey of molecular toxicology in the pharmaceutical industry is contributed by a pioneer in this field. The third section addresses the effect of xenobiotics on cell-cycle actors. Sections 4--6 deal with molecular toxicology in skin, kidney, nerve, liver and pancreatic cells. The last two sections describe methods to probe DNA damage and repair, and immunotoxicity.
