The total number of papers, conferences, abstracts and patents dedicated to cyclodextrins by the end of 1995 will be about 12,000 in number. This vast number of publications deals with the chemistry (structure, chemical reactivity), biology (enzymology, metabolism, toxicity, direct therapeutic effects), inclusion complex forming capacity and its consequences, and industrial utilization of cyclodextrins (in drugs, foods, cosmetics, chromatography, catalysis biotechnology, diagnostics etc) in unlimited numbers of products and technologies.This volume pulls all this information together, covering the chemistry, biology and industrial application of cyclodextrins as molecular encapsulating agents in research methods, analytical procedures, industrial technologies and products.

The rapidly growing number of papers and patents on Cyclodextrins and their potential or actual industrial uses raised the idea to organize a Symposium on Cyclodextrins. This Symposium - held in September 1981 in Budapest, with more than 200 participants from 17 countries - proved to be very succesfull in every respect, therefore it has been accepted unanimously to organize the lInd CD-Symposium in 1984, in Tokyo. (The Budapest-Symposium got posteriorly the "First" adjective). The IInd Symposium was held together with the III. Int. Symposium on Chlatrate Compounds and Molecular Inclusion Phenomena. The IIIrd CD-Symposium also was held as a Joint Symposium, with the IVth. Chlatrate Symposium in Lancaster, U. K. ,1986. The limited time however showed, that such a broad field - from calixarenes to zeolites - can not be managed efficiently. Therefore the International Organizing Committee voted for separation of two Symposia in the future. The IVth Int. CD-Symposium was held in the Munich, in April 1988, and the Vth Chlatrate Symposium (called already Vth Int. Symposium on Inclusion Phenomena and Molecular Recognition) was held in Alabama, Sept. 1988. In Munich 220 participants from 21 countries attended 32 verbal lectures and 54 posters. This volume contains the submitted 71 manuscripts of the IVth Cyclodextrin Symposium.

Nearly 3000 papers and patents are dedicated to the actual or potential uses of cyclodextrins in pharmacy and pharmaceutical formulations. This book, written for pharmacists and pharmaceutical technologists, not only critically summarizes the literature available, but can also be used as a handbook when looking for solutions to practical problems. The fundamentals, chemistry of cyclodextrins and their derivatives, their physical and chemical properties are condensed to the most relevant items in Chapters 1 and 2. Chapter 3 deals with the adsorption, metabolism and toxicological properties of cyclodextrins. Chapter 4 explains the formulation, structure, composition and advantageous effects of the cyclodextrin inclusion complexes. Chapter 5 describes the methods for preparation and characterization of drug/cyclodextrin complexes. Chapters 6 and 7 are dedicated to the pharmacokinetics, biopharmaceutical and technological aspects of drug/CD complexes. Chapter 8 treats the application and effects of cyclodextrins in various drug formulations. The Appendix comprises a collection of recipes for any type of drug formulation.This book is aimed at those who use cyclodextrins in drug formulations, to improve the properties of existing drug formulations, or who want to prepare new formulations.

The 147 symposium papers collected here represent a summary of achievement in this field between 1995 and 1997, with applications in such diverse disciplines as pharmaceuticals, food, cosmetics, textiles, plastics, and chromatography. Features of the text include: lipophilicity profiles of cyclodextrins by computer molecular graphics; recent toxicological studies on cyclodextrins; Buckminsterfullerene/cyclodextrin complexes; hydroxypropyl-b-cyclodextrin; pharmacokinetics and toxicology; peracylated cyclodextrins as drug carriers; cyclodextrins in nasal drug delivery; textile fibre surface modification by a reactive cyclodextrin; cyclodextrin-containing fabric care products; drug targeting by cyclodextrin-dimers for photodynamic cancer therapy; cyclodextrins in ophthalmologic drugs; and new cyclodextrin derivatives and their potentials.

Nearly three thousand papers and patents are dedicated to the actual or potential uses of cyclodextrins in pharmacy and pharmaceutical formulations. This is the first book written for pharmacists and pharmaceutical technologists which not only critically summarizes the enormous amount of literature available, but which can be used as a handbook when looking for solutions to practical problems. The fundamentals -- chemistry of cyclodextrins and their derivatives -- their physical and chemical properties are condensed to the most relevant items in Chapters 1 and 2. Chapter 3 deals with the adsorption, metabolism and toxicological properties of cyclodextrins. Chapter 4 explains the formulation, structure, composition and advantageous effects of the cyclodextrin inclusion complexes. Chapter 5 describes the methods for preparation and characterization of drug/cyclodextrin complexes. Chapters 6 and 7 are dedicated to the pharmacokinetics, biopharmaceutical and technological aspects of drug/CD complexes. Chapter 8 treats the application and effects of cyclodextrins in various drug formulations. The Appendix comprises a collection of recipes for any type of drug formulation. This book is aimed at those who use cyclodextrins in drug formulations, to improve the properties of existing drug formulations, or who want to prepare quite new formulations.

Cyclodextrins are galnlng industrial interest owing to their particu- lar structure. These cyclic amyloses are commonly composed of 6, 7 or 8 (named a-, 8-, y-CD) glucose units. They undergo complexation with quite a large number of substances by molecular inclusion. Their potential for in- dustrial application is substantiated by their ability to protect fragile substances from oxygen and UV, to delay the evolution of volatiles and to aid the ancillary processing of dangerous or volatile substances in powder- ed form. Though a-, 8- and y-CD exhibit different inclusion specificity, 8-CD has found more attention than the others. This is due to the fact that most of the cyclodextrin producing enzymes known produce predominantly 8-CD. Fur- thermore 8-CD is by far the least soluble form, leading to a relatively sim- ple production and purification. Consequently 8-CD is already in production on an industrial scale [~] while a- and 8-CD are still more or less re- garded as specialities. A further CD-producing enzyme has been found in the medium of K. pneu- moniae [l], Since this CGT appeared to produce predominantly a-CD [~], it has been chosen to develop a process for the production of a-CD.MATERIALS AND METHODS Analysis of cyclodextrins: HPLC on Lichrosorb-NH . 10 ~m, with acetonitrile 2 water 65/35 per volume. Test for CGT activity: as described by Landert elsewhere in this Volume. Starch: potato starch as obtained from Blattmann, Wadenswil, Switzerland.
