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.
Cancer is a great challenge to efficient therapy due to biological diversity. Disturbed oxidative homeostasis in cancer cells certainly contributes to differential therapy response. Further, one of the hallmarks of cancer cells is adaptation which includes fine tuning of the cellular metabolic and signalling pathways as well as transcription profiles. There are several factors which contribute to the tumor diversity and therapy response, and oxidative stress is certainly one of them. Changes in oxygen levels due to hypoxia/reoxygenation during tumor growth modulate antioxidative patterns finally supporting increased cell diversity and adaptation to stressing conditions. Additionally, cancer chemotherapy based on ROS production can also induce also adaptation. To counteract these negative effects natural products are often used for their antioxidant activities as well as photodynamic therapy supported by novel chemosensitizers. Understanding of possible pathways which can trigger antioxidant defence at a certain time during cancer development can also provide possible strategies in fighting cancer.
This eBook is a collection of articles from a Frontiers Research Topic. Frontiers Research Topics are very popular trademarks of the Frontiers Journals Series: they are collections of at least ten articles, all centered on a particular subject. With their unique mix of varied contributions from Original Research to Review Articles, Frontiers Research Topics unify the most influential researchers, the latest key findings and historical advances in a hot research area! Find out more on how to host your own Frontiers Research Topic or contribute to one as an author by contacting the Frontiers Editorial Office: frontiersin.org/about/contact.

This volume investigates the various ways in which writers comment on, present, and defend their own works, and at the same time themselves, across early modern Europe. A multiplicity of self-commenting modes, ranging from annotations to explicatory prose to prefaces to separate critical texts and exemplifying a variety of literary genres, are subjected to analysis. Self-commentaries are more than just an external apparatus: they direct and control reception of the primary text, thus affecting notions of authorship and readership. With the writer understood as a potentially very influential and often tendentious interpreter of their own work, the essays in this collection offer new perspectives on pre-modern and modern forms of critical self-consciousness, self-representation, and self-validation. Contributors are Harriet Archer, Gilles Bertheau, Carlo Caruso, Jeroen De Keyser, Russell Ganim, Joseph Harris, Ian Johnson, Richard Maber, Martin McLaughlin, John O’Brien, Magdalena Ożarska, Federica Pich, Brian Richardson, Els Stronks, and Colin Thompson.
