Polycyclic hydrocarbons are of interest in many fields of science: theoretical chemistry, physical chemistry, organic chemistry, dyestuff chemistry and biology. With regard to the latter, I am indebted to Dr. Regina Schoental of the Medical Research Council for the review in this present work of carcinogenesis by polycyclic hydrocarbons. This book is designed to present the facts in a simple and clear order and to derive empirical rules from them, but it does not present a com prehensive theory about polycyclic hydrocarbons. An attempt is made instead to extend classical symbolism into modern structural chemistry. Thus extensive use is made of Robinson's aromatic sextet, which is applied in an uncompromising and strict way. This quasi-classical attempt is encouraged further by such completely unexpected dis coveries as those of Dewar benzene and of the electronic asymmetry of formally symmetric hydrocarbons. How difficult it is to break away from any established way of thinking has been admirably expressed by Kekule ("Organische Chemie," 1861, Part 1, page 4, translated from the German): "All our ideas are based, to an extent much greater than we ordinarily believe, on those of our predecessors. Our accumulated experience, the notions of which our training has accustomed us to, of whatever kind they have been, influence the course of our thoughts far more than we are willing to admit; only too frequently the following of our regularly used, well trodden way of thinking leads us to overlook the simplest of correlations."

The field of DNA vaccines has undergone explosive growth in the last few years. As usual, some historical precursors of this approach can be d- cerned in the scientific literature of the last decades. However, the present state of affairs appears to date from observations made discreetly in 1988 by Wolff, Malone, Felgner, and colleagues, which were described in a 1989 patent and published in 1990. Quite surprisingly, they showed that genes carried by pure plasmid DNA and injected in a saline solution, hence the epithet "naked DNA," could be taken up and expressed by skeletal muscle cells with a low but reproducible frequency. Such a simple methodology was sure to spawn many applications. In a separate and important line of experimentation, Tang, De Vit, and Johnston announced in 1992 that it was indeed possible to obtain humoral immune responses against proteins encoded by DNA delivered to the skin by a biolistic device, which has colloquially become known as the "gene gun. " The year 1993 saw the publication of further improvements in the me- ods of naked DNA delivery and, above all, the first demonstrations by several groups of the induction of humoral and cytotoxic immune responses to viral antigens expressed from injected plasmid DNA. In some cases, protection against challenge with the pathogen was obtained. The latter result was - questionably the touchstone of a method of vaccination worthy of the name.

This Adis Pocket Reference presents an up-to-date, succinct, and practical approach to drug therapy for type 2 diabetes.

Combinatorial chemistry and molecular diversity approaches to scientific inquiry and novel product R&D have exploded in the 1990s! For example, in the preparation of drug candidates, the automated, permutational, and combinatorial use of chemical building blocks now allows the generation and screening of unprecedented numbers of compounds. Drug discovery - better, faster, cheaper? Indeed, more compounds have been made and screened in the 1990s than in the last hundred years of pharmaceutical research. This first volume covers: (i) combinatorial chemistry, (ii) combinatorial biology and evolution, and (iii) informatics and related topics. Within each section chapters are prepared by experts in the field, including, for example, in Section I: Coverage of mixture pools vs. parallel individual compound synthesis, solution vs. solid-phase synthesis, analytical tools, and automation. Section II highlights selection strategies and library-based evolution, phage display, peptide and nucleic acid libraries. Section III covers databases and library design, high through-put screening, coding strategies vs. deconvolutions, intellectual property issues, deals and collaborations, and successes to date.

This classic work by Poucher, first published in 1923, was last produced in three volumes titled, respectively The Raw Materials of Perfumery (seventh edition, 1974), The Production, Manufacture and Application of Perfumes (eighth edition, 1974) and Modern Cosmetics (eighth edition, 1974). Its popularity is well demonstrated by there having been three reprints of these editions in 1976, 1979 and 1984, res pecti vel y . The history of events can be traced by reference to the prefaces to earlier editions and those interested should study these with care since they give a fascinating insight into developments in the subject fields covered by Poucher's Perfumes, Cosmetics and Soaps over the years. It is not proposed to provide a resume here. In this Volume I, the current edition attempts to provide data about raw materials in a more formalized way than before, so that not only the history of some compounds can be checked, but also so that useful reference information can be obtained. It is particularly relevant to do this, since it is not always easy to be certain of nomenclature. Moreover, as we move towards 'ingredient labelling' (a trend not welcomed by some), a high level of uniformity will be needed. Whether this will come from adoption of CTFA terminology, use of CAS numbers or some other system is not clear. Where possible, such data have been included so that readers may identify materials more readily. Where given, CAS numbers are located in the top right-hand corner of each entry.

Advances in understanding the molecular mechanisms of disease together with the advent of recombinant DNA and other technologies have opened opportunities for a vast array of novel therapeutic biopharmaceuticals and diagnostic agents. However, even natural biomolecules present a myriad of problems that limit their potential as pharmaceutical agents. Rapid degra- tion and elimination, immunological reactions, and toxicity are often asso- ated with new biopharmaceuticals, much as with conventional agents. Targeted delivery systems have the potential to increase the efficacy of existing diagnostic and therapeutic agents and also create an opportunity for the use of new pharmaceuticals, substances that themselves can be harmful to normal tissues. Both passive and active targeting have been exploited. Most active targ- ing strategies have focused on antibody conjugates since preparation of highly specific monoclonal antibodies is well established. However, a new wave of c- jugates exploiting other ligands is underway. Access to the target tissue remains an obstacle and is an area where passive targeting can be useful. In Drug Targeting: Strategies, Principles, and Applications we have tried to compile a state-of-the-art volume on current targeting approaches. The first section focuses on certain key strategies applied to date, and how to build the antibody- ligand constructs. This is followed by a section on theoretical considerations for t- geting, focusing on approaches relevant to solid tumors. The last section deals with some experimental and clinical applications of targeted drug delivery systems.

This volume summarizes current research on the influence of plant polyphenols on human health, promoting collaboration between chemists and biologists to improve our understanding of their biological significance, and expanding the possibilities for their use.

Volume 4 of the Encyclopedia of the Alkaloids covers the literature to the end of 1981 and includes those compounds which have been discovered since Volume 3 was published in 1977. There is also a small number of entries giving recently determined structure or addi tional information regarding alkaloids given in the preceding three volumes. It is a great pleasure to thank the staff of the John Rylands Science Library of the Univer sity of Manchester for kindly providing me with access to the literature on this subject.

In the pharmaceutical industry, the incorporation of the disciplines of pharma- kinetics, pharmacodynamics, and drug metabolism (PK/PD/DM) into various drug development processes has been recognized to be extremely important for approp- ate compound selection and optimization. During discovery phases, the identifi- tion of the critical PK/PD/DM issues of new compounds plays an essential role in understanding their pharmacological profiles and structure-activity relationships. Owing to recent progress in analytical chemistry, a large number of compounds can be screened for their PK/PD/DM properties within a relatively short period of time. During development phases as well, the toxicology and clinical study designs and trials of a compound should be based on a thorough understanding of its PK/PD/DM properties. During my time as an industrial scientist, I realized that a reference work designed for practical industrial applications of PK/PD/DM could be a very valuable tool for researchers not only in the pharmacokinetics and drug metabolism departments, but also for other discovery and development groups in pharmaceutical companies. This book is designed specifically for industrial scientists, laboratory assistants, and managers who are involved in PK/PD/DM-related areas. It consists of thirteen chapters, each of which deals with a particular PK/PD/DM issue and its industrial applications. Chapters 3 and 12 in particular address recent topics on higher throughput in vivo exposure screening and the prediction of pharmacokinetics in humans, respectively. Chapter 8 covers essential information on drug metabolism for industrial scientists.

This volume was planned to provide a comprehensive survey of the role of the anabolic-androgenic steroids in the vital economy exclusive of the androgenic (sexual) functions. It seemed appropriate to bring together all of this information in an organized fashion in one volume at this time not only to serve as a source of information but also to indicate and suggest areas that need further exploration. The anabolic action of the steroid hormones has gone through a period of great activity in both basic and clinical research. A complete understanding of the manifold anabolic effects still remains to be elucidated and the art of clinical application is only gradually becoming apparent. This volume should be useful not only to the experienced investigator in both basic and clinical research but also for the novice. Furthermore, it should serve as a source of information for the careful use of these steroids in certain metabolic diseases. These steroids have had wide clinical application with variable results. In many instances further careful exploration is suggested. Other instances have demonstrated varying degrees of usefulness.

"Der wichtigste Schritt in der Fortentwicklung aller Naturwissenschaften ist mit der Einfuhrung der Messung von Grossen gemacht worden. " (J. C. MAXWELL, Theorie der Warme, Dt. uber- setzung nach der 4. Aufl. , 1877) Die Analyse des Elektrolyt- und Wasserhaushaltes bei Patienten mit generali- sierten Odemen hat ergeben, dass die Unfahigkeit des Organismus, die mit der Nahrung zugefuhrten Natriumionen quantitativ zu eliminieren, ein gemeinsames Merkmal dieser Erkrankungen ist. Die Ansammlung von Wasser im extracellularen Raum ist lediglich die Folge dieser Natriumretention. Der Anteil der Niere an der Entstehung solcher Storungen des Elektrolyt- und Wasserhaushalts beruht auf der I mbalance glomerular-tubularer Funktionen, die renale und extrarenale Ursachen haben kann. Die Minderung der glomerularen Filtration ist fur die Entstehung der Odeme sicher von geringerer Bedeutung als die zu intensive Ruckgewinnung des Primarharns unter den pathologischen Bedingungen, die den Ausgleich der gestorten Salz- und Wasserbilanz verhindert. Prinzipiell kann eine Vermehrung der Harnausscheidung sowohl durch Ver- grosserung der glomerularen Filtration als auch durch Hemmung der tubularen Ruckgewinnung des Primarharns erreicht werden. Die heute gebrauchlichen Diuretica verandern ganz uberwiegend tubulare Funktionen und beeinflussen daher den an zweiter Stelle genannten Prozess.

Consumer interest in diet and nutritional supplements is increasing dramatically. Patients and members of the public are seeking advice from health professionals, nutritionists and food scientists. This book is designed to meet the needs of those professionals who are called upon to advise patients and the general public. It provides also a valuable text for those who are researchers or decision makers in the food and pharmaceutical industries. The text presents a thorough account of this topical subject and enables the reader to appreciate the functions of nutrients in health and common disease states, to understand the current debates over the roles of nutrients and supplements in the diet, and to answer those questions frequently asked by patients and consumers.

Founded in 1959 by its current Editor, the series has moved from its initial focus on medicinal chemistry to a much wider scope. Today it encompasses all fields concerned with the development of new therapeutic drugs and the elucidation of their mechanisms of action, reflecting the increasingly complex nature of modern drug research. Invited authors present their biological, chemical, biochemical, physiological, immunological, pharmaceutical, toxicological, pharmacological and clinical expertise in carefully written reviews and provide the newcomer and the specialist alike with an up-to-date comprehensive list of prime references. Each volume of Progress in Drug Research contains fully cross-referencing indices which link the books together, forming a virtually encyclopaedic work. The series thus serves as an important, time-saving source of information for researchers concerned with drug research and all those who need to keep abreast of the many recent developments in the quest for new and better medicines.

In the past few years, antisense methodology has moved from in vitro studies to in vivo studies and first human trials. While the basic concept of antisense technology is simple, the methodological problems associated with its use are numerous and complex. Antisense- based methods have proven to be a field of research where careful attention to experimental protocols and appropriate controls is necessary. The Manual of Antisense Methodology emphasizes the application of antisense oligonucleotides, and is a guide for the identification of antisense and non-antisense effects in different experimental settings. The work is organized into three sections: antisense application in vitro, antisense application in vivo (animal models) and finally, clinical antisense studies. Where at all possible, the methods are described in sufficient detail to allow reproduction of a given experiment. The Manual of Antisense Methodology will be of interest to researchers in immunology, cancer research, pharmacology and internal medicine; and physicians conducting clinical studies in these fields.

This collection takes the perspective that the historiography of science, technology, and medicine needs a broader approach toward regulation. The authors explore the distinct social worlds involved in regulation, the forms of evidence and expertise mobilized, and means of intervention chosen to tame drugs in factories, consulting rooms and courts.

If the antibody industry is to achieve its full potential in the next decade, the individual technical potentials must be exploited, the limitations must be addressed, and lessons learned must be applied both to current purification methods and to the new technologies that continue to emerge. This book presents an overview of the current advances applied in the manufacture of monoclonal antibody including: -concepts in development of manufacturing strategies, -importance of antibody fragments, -application of chromatography method development, -quality control, -effect of expression on antibody properties, -virus removal and safety, -pharmacokinetics, -regulatory aspects.

Advances in molecular biology and recombinant DNA technology have accelerated progress in many fields of life science research, including gene therapy. A large number of genetic engineering approaches and methods are readily available for gene cloning and therapeutic vector construction. Significant progress is being made in genomic, DNA sequencing, gene expression, gene delivery and cloning. Thus gene therapy has already shown that it holds great promise for the treatment of many diseases and disorders. In general it involves the delivery of recombinant genes or transgenes into somatic cells to replace proteins with a genetic defect or to transfer with the pathological process of an illness. The viral and non-viral delivery systems may hold the potential for future non-invasive, cost-effective oral therapy of genetically-based disorders. Recent years have seen considerable progress in the discovery and early clinical development of a variety of gene therapeutic products. The availability, validation, and implementation of gene therapeutic products has also enabled success in testing and evaluation. New challenges will need to be overcome to ensure that products will also be successful in later clinical development and ultimately for marketing authorisation. These new challenges will include improvements in delivery systems, better control of in-vivo targeting, increased level transduction and duration of expression of the gene, and manufacturing process efficiencies that enable reduction in production costs. Perhaps profound understanding of regulated gene design may result in innovative bioproducts exhibiting safety and efficacy profiles that are significantly superior to those achieved by the use of naturally occurring genes. This procedure may contribute considerably to fulfilling standards set by regulatory authorities. This book provides an overview of the current advances in the field of gene therapy and the methods that are being successfully applied in the manufacture of gene therapeutic products, and hopefully will stimulate further progress and advancement in this field to meet the ever-increasing demands.

Seven review articles and original papers provide a representative overview of the research work done in hydrogen bond research at Austrian universities. The topics covered by the contributions are: state-of-the-art of understanding hydrogen bonding in biopolymers; recent NMR techniques for studying hydrogen bonding in aqueous solutions; intramolecular hydrogen bonding and proton transfer in a class of Mannich bases derived from substituted phenols and naphthols; competition between intramolecular hydrogen bonds in ortho-disubstituted phenols; molecular dynamic simulations on proton transfer in 5,8-dihydroxynaphthoquinone and in the formic acid dimer; accurate calculations of the intermolecular interactions in cyanoacetylen dimers; correlation between OH...O bond distances and OH stretching frequencies as derived from structural and spectroscopic data of minerals.

Protein Glycosylation provides clear, up-to-date, and integrated coverage of key topics in this field. Particular emphasis is placed on the biosynthetic pathways that result in a wide variety of identified protein-bound oligosaccharides. Protein Glycosylation begins with an overview of the chemical structures of mono- and oligosaccharides, to provide a scientific basis for the later chapters. The book includes discussions on the purification, function, and enzyme kinetics of selected glycosidases and glycotransferases, as well as a review of the roles of oligosaccharides in glycoprotein function and the in vivo role of glycoproteins themselves. Finally, the in vitro synthesis of glycoproteins is presented, together with future directions in glycobiology. Protein Glycosylation serves as an excellent text for upper-level undergraduate and graduate students as well as a reference for those scientists whose training is not in glycobiology but who are moving into this field.

This useful work presents a current overview of key genes involved in the control of apoptosis research together with thoughts on future prospects and clinical applications. While there are several books written on apoptosis, this one deals specifically with its regulation.

Much of chemistry, molecular biology, and drug design, are centered around the relationships between chemical structure and measured properties of compounds and polymers, such as viscosity, acidity, solubility, toxicity, enzyme binding, and membrane penetration. For any set of compounds, these relationships are by necessity complicated, particularly when the properties are of biological nature. To investigate and utilize such complicated relationships, henceforth abbreviated SAR for structure-activity relationships, and QSAR for quantitative SAR, we need a description of the variation in chemical structure of relevant compounds and biological targets, good measures of the biological properties, and, of course, an ability to synthesize compounds of interest. In addition, we need reasonable ways to construct and express the relationships, i. e. , mathematical or other models, as well as ways to select the compounds to be investigated so that the resulting QSAR indeed is informative and useful for the stated purposes. In the present context, these purposes typically are the conceptual understanding of the SAR, and the ability to propose new compounds with improved property profiles. Here we discuss the two latter parts of the SARlQSAR problem, i. e. , reasonable ways to model the relationships, and how to select compounds to make the models as "good" as possible. The second is often called the problem of statistical experimental design, which in the present context we call statistical molecular design, SMD. 1.
