Anubrata Ghosal describes for SIIC the most significant aspects of his article describe para SIIC los aspectos relevantes de su artículo PEPTIDE NUCLEIC ACID HOLDS THE PROMISE OF NOVEL ANTIBIOTICS In this current study, we have developed four antisense peptide-PNA conjugates by targeting two widely conserved bacterial genes, acpP and ftsZ. These molecules can completely inhibit the growth of several P. aeruginosa strains at 1-2 μM concentrations. The article was published by El artículo fue publicado por
