Modern medicine is impossible without antibiotics, but global antibiotic usage has led to the development of increasing numbers of multi-drug resistant (MDR) bacteria. Thus, we still have problems with infectious disease treatment despite an arsenal of antibiotics. This has forced researchers to develop new drugs that will be effective against resistant bacteria. Some of these prospective molecules are antimicrobial peptides (AMPs), which are an important component of the innate immune system of various organisms in nature. Currently, more than 3,000 AMPs have been reported with different activities against different bacterial species including resistant phenotype bacteria. AMPs display remarkable structural and functional diversity that is not completely understood. As such, this book presents a comprehensive overview of AMPs and their mechanism of action against MDR bacteria.

In this text, the small team of expert authors presents the field in a comprehensive and accessible manner that is well suited for students and junior researchers. The result is a highly readable and systematically structured introduction to antimicrobial peptides, their structure, biological function and mode of action. The authors point the way towards a rational design of this potentially highly effective new class of clinical antibiotics on the brink of industrial application. They do this by discussing their design principles, target membranes and structure-activity relationships. The final part of the book describes recent successes in the application of peptides as anticancer agents.

The emergent resistance of bacteria against the conventional antibiotics has motivated the search for novel antimicrobial agents. Nature abounds with a number of antimicrobial peptides that are a part of our innate immune system and protect us against a variety of pathogenic bacteria. While they are broad-spectrum in their activity and show less drug-resistance induction, their intrinsic metabolic stability limits their potential therapeutic applications. Herein we describe the development of novel broad-spectrum bioactive antimicrobial peptidomimetics AA-peptides. AApeptides were designed based on chiral PNA backbone. Substitution of nucleobases yields AApeptides that are resistant to proteolysis and capable of mimicking peptides. Two types of AApeptides are discussed in this dissertation "á-AApeptides" and " ã-AApeptides" The therapeutic potential of these AApeptides were accessed by conducting antibacterial assays against a series of both gram-positive, gram-negative bacteria and fungi. These oligomers were characterized using MALDI-TOF and Circular Dichroism spectroscopy (CD). Their invitro toxicity was evaluated against human erythrocytes .We attempted to study their mechanism of action via membrane depolarization assay. We have successfully identified them as antimicrobial agents, pro-inflammatory immune response suppressing agents and as anti-biofilm agents.
