Abstract
The proline-rich antimicrobial peptide (PrAMP) Drosocin (Dro) from fruit flies shows sequence similarity to other PrAMPs that bind to the ribosome and inhibit protein synthesis by varying mechanisms. The target and mechanism of action of Dro, however, remain unknown. Here we show that Dro arrests ribosomes at stop codons, probably sequestering class 1 release factors associated with the ribosome. This mode of action is comparable to that of apidaecin (Api) from honeybees, making Dro the second member of the type II PrAMP class. Nonetheless, analysis of a comprehensive library of endogenously expressed Dro mutants shows that the interactions of Dro and Api with the target are markedly distinct. While only a few C-terminal amino acids of Api are critical for binding, the interaction of Dro with the ribosome relies on multiple amino acid residues distributed throughout the PrAMP. Single-residue substitutions can substantially enhance the on-target activity of Dro.

Abstract
Antimicrobial peptides (AMPs) are promising novel antibiotics since they have shown antimicrobial activity against a wide range of bacterial species, including multiresistant bacteria; however, toxicity is the major barrier to convert antimicrobial peptides into active drugs. A profound and proper understanding of the complex interactions between these peptides and biological membranes using biophysical tools and model membranes seems to be a key factor in the race to develop a suitable antimicrobial peptide therapy for clinical use. In the search for such therapy, different combined approaches with conventional antibiotics have been evaluated in recent years and demonstrated to improve the therapeutic potential of AMPs. Some of these approaches have revealed promising additive or synergistic activity between AMPs and chemical antibiotics. This review will give an insight into the possibilities that physicochemical tools can give in the AMPs research and also address the state of the art on the current promising combined therapies between AMPs and conventional antibiotics, which appear to be a plausible future opportunity for AMPs treatment.

Abstract
Antimicrobial peptides are small molecules with activity against bacteria, yeasts, fungi, viruses, bacteria, and even tumor cells that make these molecules attractive as therapeutic agents. Due to the alarming increase of antimicrobial resistance, interest in alternative antimicrobial agents has led to the exploitation of antimicrobial peptides, both synthetic and from natural sources. Thus, many peptide-based drugs are currently commercially available for the treatment of numerous ailments, such as hepatitis C, myeloma, skin infections, and diabetes. Initial barriers are being increasingly overcome with the development of cost-effective, more stable peptides. Herein, we review the available strategies for their synthesis, bioinformatics tools for the rational design of antimicrobial peptides with enhanced therapeutic indices, hurdles and shortcomings limiting the large-scale production of AMPs, as well as the challenges that the pharmaceutical industry faces on their use as therapeutic agents.

Abstract
One of the obvious disadvantages of natural peptides is their liability to proteases. Among the several solutions for this issue, peptoids or oligomers of N-substituted glycine have emerged as a promising tool that may enhance the stability of proteolysis-susceptible natural peptides. We have synthesized the drosocin and its glyco-peptoid analogues linked O-GalNAc at the Thr(11) residue. One of our glyco-peptoid analogues showed an increased antibacterial activity by the modification of the Thr(11) residue with glyco-peptoid. Structure-activity relationship studies revealed that the antibacterial activity by glyco-peptoid drosocin requires three key elements: free hydroxyl group on the carbohydrate moiety, γ-methyl group of the Thr(11) residue derivative and (S)-configuration over (R)-configuration.

Abstract
Drosocin is a 19-mer, cationic antimicrobial peptide from Drosophila melanogaster. The aim of the study was to examine the antibacterial spectrum of unglycosylated drosocin analogues. Furthermore, the amino acid sequence of DnaK, drosocin's intracellular target, from susceptible species was aligned and studied for sequence homology. From this a panel of 31 bacterial strains, including Salmonella strains with truncated lipopolysaccharide structures, was tested for susceptibility towards three drosocin analogues. Available bacterial DnaK amino acid sequences were retrieved from the ExPASy proteomics server of the Swiss Institute of Bioinformatics studied for sequence homology. Seventeen of the 31 strains tested were susceptible for the drosocin analogues. Minimal inhibitory concentration values against mainly Gram-negative bacteria ranged from 3.1 to 100 microm. With the exception of Micrococcus luteus and Xanthomonas campestris all drosocin analogue-susceptible strains were Enterobacteriaceae showing a high DnaK amino acid sequence homology.
