Seit ihrer Erfindung in den fünfziger Jahren hat die NMR-Spektroskopie ihren festen Platz in der Aufklärung der zweidimensionalen Struktur neu synthetisierter Substanzen sowie von Stoffen natürlichen Ursprungs. Mit der Einführung der Hochfeldgeräte in den achtziger Jahren konnten zweidimensionale Experimente (HETCOR, COSY) durchgeführt werden, mit deren Hilfe sich die dreidimensionale Struktur auch von sehr großen Molekülen, wie Biomolekülen, aufklären ließ. Obgleich jetzt mit der Einführung Hochfeld-NMR-Geräte eine sehr empfindliche Methode zur Verfügung stand, wurden NMR-Spektren nur selten zur quantitativen Analyse von Arzneistoffen herangezogen. Das hier vorliegende Buch hat zum Ziel, die Möglichkeiten und Grenzen der NMR-Spektroskopie in der Analytik rund um den Arzneistoff aufzuzeigen: Dazu zählen die quantitative Bestimmung von Arzneistoffen und der in ihnen enthaltenen Verunreinigungen, die Charakterisierung von polymeren Hilfsstoffen oder Mischungen isomerer Arzneistoffe und von Komplexen aus Arzneistoffen mit kleinen und großen Komponenten (der Hilfsstoffe in der Arzneizubereitung) sowie das Verhalten von Arzneistoffen im Sauren und Basischen. Die Kopplung der NMR-Spektroskopie mit der HPLC bietet die Möglichkeit, sehr einfach Arzneistoffe und ihre Metaboliten in Körperflüssigkeiten zu identifizieren. Die Solid-State-Technik kann dem Pharmazeutischen Technologen wichtige Informationen über die dreidimensionale Struktur von Arznei- und Hilfsstoffen in einer Arzneizubereitung oder einem Pulver geben. Die kürzlich von Fesik beschriebene Möglichkeit der Analyse von Struktur-Wirkungs-Beziehungen mit Hilfe der NMR-Spektroskopie unterstreicht deren Bedeutung in der Arzneistoffentwicklung. Die Charakterisierung von Komplexen aus Arzneistoffen mit großen Molekülen wie Proteinen oder Membranbestandteilen, also mit den Zielstrukturen der Arzneistoffe, ist schon seit längerem ein fester Bestandteil des "Drug Design". Zuletzt wird auf das NMR-Imaging eingegangen, das zur Visualisierung der Arzneistofffreisetzung aus Zubereitungen, aber auch der Verteilung von Substanzen in lebenden Tieren, Menschen, Geweben oder Pflanzen dient. Alles in allem zeigt dieses Buch, daß die NMR-Spektroskopie nicht nur ihre Funktion in der Strukturaufklärung hat, sondern mehr als bisher zur Analyse von Arzneistoffen herangezogen werden kann.

Since the development of the NMR spectrometer in the 1950s, NMR spectra have been widely used for the elucidation of the 2D structure of newly synthesized and natural compounds. In the 1980s, the high-resolution NMR spectrometer (> 300 Mhz) and 2D experiments were introduced, which opens up the possibility to determine the 3D structure of large molecules, especially biomolecules. However, NMR spectroscopy has been rarely applied to drug analysis. This book illustrates the power and versatility of NMR spectroscopy in the determination of impurities in and the content of drugs, the composition of polymer excipients, the characterization of isomeric drug mixtures, the complexity of drugs with small-size components or ions, and the behavior of drugs in acid and basic solution. In addition, NMR spectroscopy and especially the hyphenated technique with HPLC is shown to be a powerful tool to measure a drug and its metabolites in various body fluids. The solid state NMR technique can give information on the structure, especially the conformation of drugs and excipients in drug formulations. Recently, SAR by NMR, introduced by Fesik, impressively demonstrated the potential of NMR spectroscopy in drug development and in the characterization of the interaction between large molecules and ligands. The complexation between proteins, lipids and cyclodextrins with drugs is described. Finally, NMR imaging (MRI and MRS) can be used to characterize the liberation of drugs from a drug formulation. Furthermore, the distribution of substances in plants, in animals, in tissues and in humans can be visualized by imaging. In short, this book covers all aspects of drug analysis.

NMR in Pharmaceutical Sciences is intended to be a comprehensive source of information for the many individuals that utilize MR in studies of relevance to the pharmaceutical sector. The book is intended to educate and inform those who develop and apply MR approaches within the wider pharmaceutical environment, emphasizing the toolbox that is available to spectroscopists and radiologists. This book is structured on the key processes in drug discovery, development and manufacture, but underpinned by an understanding of fundamental NMR principles and the unique contribution that NMR (including MRI) can provide. After an introductory chapter, which constitutes an overview, the content is organised into five sections. The first section is on the basics of NMR theory and relevant experimental methods. The rest follow a sequence based on the chronology of drug discovery and development, firstly 'Idea to Lead' then 'Lead to Drug Candidate', followed by 'Clinical Development', and finally 'Drug Manufacture'. The thirty one chapters cover a vast range of topics from analytical chemistry, including aspects involved in regulatory matters and in the prevention of fraud, to clinical imaging studies. Whilst this comprehensive volume will be essential reading for many scientists based in pharmaceutical and related industries, it should also be of considerable value to a much wider range of academic scientists whose research is related to the various aspects of pharmaceutical R&D; for them it will supply vital understanding of pharmaceutical industrial concerns and the basis of key decision making processes.

This book presents a review of recent developments in NMR applications in pharmaceutical research. Consideration is given to consolidated and emerging techniques and methods, many of which are not yet widely applied but are likely to provide new opportunities for drug design. The first part of the book is dedicated to the description of NMR as a tool for the analysis of chemicals and their interactions with targets. The next seven chapters describe NMR approaches to investigate in vivo models of interest in drug discovery and development, with the attention focused on anatomy, function, metabolism and molecular-cellular aspects. Finally, consideration is given to the application of in vivo NMR to the identification and characterization of biomarkers with the aim of monitoring the outcome of therapeutic intervention in selected human diseases, including the study of drug metabolism and toxicity. Aimed at NMR spectroscopists, pharmacologists, imaging researchers and pharmaceutical scientists, this title is invaluable at putting NMR in context within its role in drug discovery and development. This resource is essential reading for those both new and already active in these areas.

For almost a decade, quantitative NMR spectroscopy (qNMR) has been established as valuable tool in drug analysis. In all disciplines, i. e. drug identification, impurity profiling and assay, qNMR can be utilized. Separation techniques such as high performance liquid chromatography, gas chromatography, super fluid chromatography and capillary electrophoresis techniques, govern the purity evaluation of drugs. However, these techniques are not always able to solve the analytical problems often resulting in insufficient methods. Nevertheless such methods find their way into international pharmacopoeias. Thus, the aim of the book is to describe the possibilities of qNMR in pharmaceutical analysis. Beside the introduction to the physical fundamentals and techniques the principles of the application in drug analysis are described: quality evaluation of drugs, polymer characterization, natural products and corresponding reference compounds, metabolism, and solid phase NMR spectroscopy for the characterization drug substances, e.g. the water content, polymorphism, and drug formulations, e.g. tablets, powders. This part is accompanied by more special chapters dealing with representative examples. They give more detailed information by means of concrete examples. Combines theory, techniques, and concrete applications—all of which closely resemble the laboratory experience Considers international pharmacopoeias, addressing the concern for licensing Features the work of academics and researchers, appealing to a broad readership
