چکیده

The efficacies of many antimicrobial peptides are greatly reduced under high salt concentrations, limiting their development as pharmaceutical compounds. Here, we describe an easy strategy to increase salt resistance of antimicrobial peptides by replacing tryptophan or histidine residues with the bulky amino acids β-naphthylalanine and β-(4,4'-biphenyl)alanine. The activities of the salt-sensitive peptide P-113 were diminished at high salt concentrations, whereas the activities of its β-naphthylalanine and β-(4,4'-biphenyl)alanine-substituted variant were less affected.

Expression and antimicrobial activity analysis of dermaseptin B1 recombinant peptides in tobacco transgenic plants

Recently, new molecular breeding and genetic engineering approaches have emerged to overcome the limitations of conventional breeding methods in generating disease-resistance transgenic plants. The use of antimicrobial peptides (AMPs) to produce transgenic plants resistant to a wide range of plant pathogens has achieved great success. Among huge number of AMPs, Dermaseptin B1 (DrsB1), an antimi...

Boosting salt resistance of short antimicrobial peptides.

The efficacies of many antimicrobial peptides are greatly reduced under high salt concentrations, therefore limiting their use as pharmaceutical agents. Here, we describe a strategy to boost salt resistance and serum stability of short antimicrobial peptides by adding the nonnatural bulky amino acid β-naphthylalanine to their termini. The activities of the short salt-sensitive tryptophan-rich p...

Comparison of Antimicrobial Properties and Toxicity of Natural S3 Peptide with Horseshoe Crab Amoebocyte Origin and its Mutants

Introduction: Antimicrobial peptides (AMPs) are compounds with antimicrobial properties that are studied widely due to the development of resistance of pathogenic bacteria to antibiotics. In the present study, the toxicity and antimicrobial effects of two natural monomeric peptides (S3 and S∆3) were compared with S3-S∆3 hybrids and S3 tetramers. Material & Methods: Protein hybrids (S∆3S3-2mer-G...

Helix stability confers salt resistance upon helical antimicrobial peptides.

Salt sensitivity of antimicrobial peptides poses a major obstacle in their development as novel antibiotics. Here we report the use of helix-capping motifs to confer salt resistance upon helical antimicrobial peptides. The helical content of the template peptide [RLLR](5) was almost completely destroyed at salt concentrations over 200 mm NaCl, leading to a 8-32-fold decrease in antimicrobial ac...

Antimicrobial peptide Brevinin-2R induces the secretion of a pro-inflammatory cytokine in HepG2 cells

Introduction: Antimicrobial peptides as the body's defense strategy play an important role in resistance against infection of microorganism. These peptides are able to modulate the immune and inflammatory processes through the production of defensive molecules. Therefore, the modulatory effects of Brevinin-2R, an antimicrobial peptide extracted from the skin of the frog (Rana ridibunda), was ev...
