There are only very few chemical classes of antibiotics in medical use, and these have originated over a span of more than 60 years of research. Almost half a century ago, the first member of the macrolides, erythromycin, was introduced as a treatment option for bacterial infections. Erythromycin is a very complex fermentation product obtained from the soil bacterium Saccharopolyspora ery thraea (originally named Streptomyces erythreus). The success of erythromycin, based on its efficacy and tolerability, stimulated researchers throughout the world to undertake intense efforts to understand the biology and chemistry of macrolides and to use this experience to improve the properties of this compound class. The second generation of macrolides, based on chemical modifications of erythromy cin, is currently being in broad use, especially for treatment of respiratory tract infections. We presently foresee the introduction of a new generation of macro lides, i. e. the ketolides, which have the potential to overcome rising resistance problems. This monograph is intended to give the interested reader an overview on "macrolide experience", covering important areas from basic research to clinical use. Starting from a historic overview, the essential basic parameters - efficacy, pharmacokinetics, pharmacodynamics, and pharmacology - are highlighted in order to introduce the reader to the rationale for clinical use of macrolides. The following group of chapters cover the complex chemistry of the macro lactone structures, giving historic background, basic structure-activity relation ships of various derivatization strategies, and perspectives for future discovery of new semisynthetic macrolide antibiotics.

Macrolide antibiotics represent a class of natural macrocyclic products, one of the most clinically important antibiotics. Unfortunately, the production and development of new macrolide antibiotics are not represented enough in the pharmaceutical industry today. The intention of the book is therefore not only to be a teaching tool for students and experts, but also to draw the attention of the general public to this extremely useful, cheap and relatively unharmful effective anti-macrobials, and potential anti-malarials. The authors introduce the different classes of macrolides and their derivatives, principles of their biological activity, their structure and interactions with biological targets as well as synthetic methods to produce new macrolide antibiotics of similar or improved properties. Special emphasis was put on conjugates of macrolides with nucleobases or nucleosides with numerous applications; among them the most important remains the attempt to overcome bacterial resistance.

For over 50 years, clinicians have known that macrolide antibiotics have effects on inflammation and the immune system that are not related to their antimicrobial properties. These immunomodulatory properties, best described for treating inflammatory airway diseases, protect the lung and the host and improve clinical status. This book summarizes our current knowledge regarding proposed mechanisms for these properties, established clinical results, and what the future may hold with emphasis on novel clinical applications and the fascinating development of non-antimicrobial macrolides with preserved and enhanced immunomodulatory properties.

Macrolide antibiotics are known as anti-bacterial agents. Erythromycin A, 14-membered macrolide antibiotic is known to exist in two forms-ketone (active) and hemiacetal form (inactive). It shows mild flexibility in silico. Its derivative, clarithromycin, 6-O-methyl erythromycin A, shows rigidity and activity against Gram-positive bacteria. The semisynthetic derivative of erythromycin A, azithromycin, 15-membered macrolide antibiotic, shows flexibility in silico and activity against Gram-negative bacteria. The combination of molecular modelling (molecular mechanics and/or molecular dynamics) with TRNOESY NMR data give us the active conformation of flexible molecules. Constraining the strong intramolecular hydrogen bonds can be helpful in the determination of the active conformation of the drug. We have developed modelling strategy for the construction of new 14- and 15-membered macrolideantibiotics with desired activity. Tylosin A and tylosin B, 16-membered macrolide antibiotics, show rigidity in silico. However, tylosin A is very unstable in aqueous solutions, so precise determination of hydrogen and carbon chemical shifts is extremely difficult. Nobody else before us tried to publish the full assignments of this compound in D2O. Accurate determination of hydrogen and carbon chemical shifts is necessary in order to further explore the properties of this compound. Anti-bacterial activity investigation of tylosin A and its derivative, tylosin B, shows lower activity both against Gram-positives and Gram-negatives compared to clarithromycin and azithromycin. Superposition of two molecules of azithromycin with one molecule of tylosin A reveals that two molecules of azithromycin actually occupy the space of one tylosin A molecule, which can explain found anti-malarial activity of tylosin A (both azithromycin and tylosin A show similar contacts to bacterial ribosomes).Clinical trials show that azithromycin has an anti-malarial activity. In order to investigate the potential anti-malarial activity of macrolide antibiotics, we had to construct the exit tunnel of the apicoplast ribosome from Plasmodium falciparum. Because of the unavailability of the crystal structure of P. falciparum ribosome (it is impossible to separate mitochondria and apicoplast, and both of them contain ribosomes), we used different computational methods and softwares in order to construct it. We used both homology modelling and ab initio modelling server for the construction of L4 (apicoplast-encoded P. falciparum ribosomal protein) and L22 (nuclear genome-encoded P. falciparum ribosomal protein) and RNA_2D3D software to construct the 23S rRNA from apicoplast ribosome of Plasmodium falciparum. Using Pymol software and MOE we have constructed the exit tunnel of apicoplast ribosome from P. falciparum. The model shows that it can bind one azithromycin molecule. It is the first model of the exit tunnel of the apicoplast ribosome from Plasmodium falciparum. Further work can be extended to the docking of other molecules than azithromycin into the modelled exit tunnel of Plasmodium falciparum.

Although the potential for immunomodulation has been recognized for many years there has been an explosion of data in this field with relevance especially to the treatment of chronic airway diseases. Most of the work in this field has been conducted by Japanese investigators but in the last decade there has been a body of work outside of Japan that supports and enhances these findings. The book covers basic research like effects on bacteria, anti-inflammatory and mucoregulatory effects, but also clinical results with up-to-date information for the use of such medications to potentially treat diseases as diverse as chronic airway diseases, arthritis, inflammatory bowel disease, and cancer. The volume is intended for pulmonary physicians, researchers in inflammation research, and pharmaceutical companies interested in the development of such agents. It provides background information for the clinician as well as in depth exploration of cutting edge science.
