Interaction of the Antimicrobial Peptide Polymyxin B1 with Both Membranes of E. coli: A Molecular Dynamics Study

Abstract:
Nos últimos anos tem havido um aumento significativo de aparecimento de estirpes, mecanismos de resistência que tem conferido resistência bacteriana a inúmeros antibióticos convencionais, assim as opções terapêuticas tendem a encurtar cada vez mais e a possibilidade de escolha dos antibióticos adequados torna-se cada vez menor. Os péptidos possuem vários mecanismos, atuando na membrana das bactérias, verificando-se uma alternativa a esses problemas existentes. Desta forma, o estudo sobre a utilização de Péptideos Antimicrobianos (AMPs do inglês Antimicrobial peptides) tornou-se impreterível devido a todo o potencial que apresentam, pois para além da sua atividade antimicrobiana também possuem ação anti-inflamatória e imunológica.In recent years there has been a significant increase in the appearance of strains, resistance mechanisms that provide bacterial resistance to the numerous conventional antibiotics, as well as therapeutic options tend to shorten more and more and the possibility of choosing the appropriate antibiotics becomes less and less. The peptides have several mechanisms, acting on the bacterial membrane, proving an alternative to these existing problems. Thus, the study on the use of Antimicrobial Peptides (AMPs from English Antimicrobial peptides) became imperative due to all the potential they present, because in addition to their antimicrobial activity they also have anti-inflammatory and immunological action
