Medication effect on the biofilm dispersion. Amino acids and their derivatives

Abstract

The scientific review presents the significance of some amino acids in the process of dispersing of bacterial biofilms. To write the article, information was searched using Scopus, Web of Science, MedLine, PubMed, Google Scholar, EMBASE, Global Health, the Cochrane Library, CyberLeninka. The influence of amino acids as nutrients on the late stages of biofilm life is considered, the effect of the D-enantiomers of amino acids on tryptophan and its derivatives on the biofilm dispersion is presented. It is emphasized that D-amino acids, namely, D-tyrosine, D-methionine, D-leucine, D-tryptophan, prevent the adhesion of amy­loid fibers, which keep the aggregation of the biofilms. D-amino acids inhibit the expression of genes involved in the production of components of the biofilm matrix, and thus realize their antibiotic effect. The ability of tryptophan to prevent the development and dispersion of biofilms, in particular those associated with the bacteria Pseudomonas aeruginosa, is highlighted. It is indicated that the role of anthranilates is to disrupt the structure of the biofilm and to stimulate the separation of sites from biofilms formed by the bacteria Pseudomonas aeruginosa. Anthranilates can help interrupt the chronicity of the infectious process. It is assumed that the use of amino acids and their derivatives, the creation of new chemical compounds that mimic the structure of amino acid molecules or alter the activity of the synthesis and degradation of certain amino acids will allow purposefully to control the life cycle of biofilms of certain types of pathogenic bacteria, which will contribute to the recovery of infectious recurrent and chronic diseases. The paper presents the prospect of developing new drugs based on anthranilic acid and halogenated indoles that promote bacterial eradication in respiratory tract infections associated with the development of bacterial biofilms of antibiotic-resistant bacterial agents.
