The aim of this book is to disseminate the most recent research in science and technology against microbial pathogens presented at the first edition of the ICAR Conference Series (ICAR2010) held in Valladolid, Spain, in November 2010. This volume is a compilation of 86 chapters written by active researchers that offer information and experiences and afford critical insights into anti-microbe strategies in a general context marked by the threat posed by the increasing antimicrobial resistance of pathogenic microorganisms. OC AntiOCO is here taken in a wide sense as OC against cell cycle, adhesion, or communicationOCO, and when harmful for the human health (infectious diseases, chemotherapy etc.) and industry or economy (food, agriculture, water systems etc.) The book examines this interesting subject area from antimicrobial resistance (superbugs, emerging and re-emerging pathogens etc.), to the use of natural products or microbes against microbial pathogens, not forgetting antimicrobial chemistry, physics and material science. Readers will find in a single volume, up-to-date information of the current knowledge in antimicrobial research. The book is recommended for researchers from a broad range of academic disciplines that are contributing in the battle against harmful microorganisms, not only those more traditionally involved in this research area (microbiologists, biochemists, geneticists, clinicians etc.), but also experimental and theoretical/computational chemists, physicists or engineers."

Peptides serve as effective drugs in the clinic today. However the inherent drawbacks of peptide structures can limit their efficacy as drugs. To overcome this researchers are developing new methods to create ‘tailor-made’ peptides and proteins with improved pharmacological properties. Design of Peptides and Proteins provides an overview of the experimental and computational methods for peptide and protein design, with an emphasis on specific applications for therapeutics and biomedical research. Topics covered include: Computer modeling of peptides and proteins Peptidomimetics Design and synthesis of cyclic peptides Carbohydrates in peptide and protein design De novo design of peptides and proteins Medical development applications An extended case study – the design of insulin variants Design of Peptides and Proteins presents the state-of-the-art of this exciting approach for therapeutics, with contributions from international experts. It is an essential resource for academic and industrial scientists in the fields of peptide and protein drug design, biomedicine, biochemistry, biophysics, molecular modelling, synthetic organic chemistry and medicinal/pharmaceutical chemistry.

Antimicrobial peptides (AMPs) represent an ancient group of molecules with diverse functions in innate immunity. To date, more than 1000 naturally-occurring AMPs have been identified which display considerable diversity in their primary sequences, lengths, structures and biological activities. Despite this variability, AMPs are broadly classified according to homologous secondary structures as cathelicidins (linear a-helical peptides), defensins (ß-strand peptides connected by disulfide bonds) and bactenecins (loop peptides). Most, but not all, AMPs are cationic with amphipathic faces. These biochemical properties bestow many peptides with potent antimicrobial activity by facilitating interactions with negatively charged microbial cell membrane components, thereby increasing membrane permeability and resulting in microbial death. Other indirect effects on microbial physiology have been reported including inhibition of DNA/RNA synthesis, impaired protein synthesis and folding, disruption of cell wall formation and inhibition of microbial cell metabolism. Thus, with the spread of antibiotic-resistant microbial pathogens, AMPs have emerged as exciting candidates for next generation anti-infective therapies. However, recent studies suggest that AMPs have evolved other mechanisms of pathogen clearance. Immunomodulation is a novel approach to antimicrobial therapy that centres on boosting host immunity rather than direct microbial killing. This is also an attractive means to treat sepsis and other immune-mediated diseases. Whilst several cationic peptides are under investigation as antimicrobial agents, a select few show a remarkable ability to protect against lethal endotoxaemia and clinically-relevant bacterial infections including methicillin-resistant Staphylococcus aureus (MRSA). The molecular mechanisms responsible for this protection are only beginning to emerge but include prevention of innate cell activation by targeting key stages of bacterial endotoxin-mediated cell signalling. In this research topic, hosted by Frontiers in Molecular Innate Immunity, we aim to highlight key areas of AMP research including peptide diversity, structure-function relationships, antimicrobial activity and mechanisms of immune-modulation. We also aim to stimulate discussion on the emerging therapeutic potential of AMPs including antifungal, antiviral and anticancer applications.
