Traitement des Rhumatismes Inflammatoires Chroniques par Golimumab en pratique courante : Étude GO-PRACTICE
Revue du Rhumatisme(2016)
Abstract
Antimicrobial activities have previously been described by traditional Eastern medicine in Chilopoda body extracts, but until now no bioactive peptides have been described. In this study, a novel antimicrobial peptide, lacrain, was isolated from the body extract of the Brazilian Chilopoda Scolopendra viridicornis. The peptide was isolated by reverse-phase high-performance liquid chromatography (RP-HPLC). Its activity was tested using a liquid growth inhibition assay and the peptide was characterised using mass spectrometry. Lacrain has a sequence composed of eight amino acid residues and a molecular mass of 925.5 Da. A synthetic peptide of the native lacrain had identical characteristics to those of the isolated material, confirming its sequence. The synthetic peptide was active only against Gram-negative bacteria, showing strong bactericidal activity. Moreover, the peptide did not present haemolytic activity against human erythrocytes. Lacrain represents a novel molecule with powerful antibacterial activity that could be used as a new template for the development of drugs against clinically resistant bacterial strains.
