Antisense peptide nucleic acids (PNAs) targeting genes involved in metabolism or virulence are a possible means to treat infections or to investigate pathogenic bacteria. Potential targets include essential genes, virulence factor genes, or antibiotic resistance genes. For efficient cellular uptake, PNAs can be coupled to cell-penetrating peptides (CPPs). CPPs are peptides that serve as molecular transporters and are characterized by a comparably low cytotoxicity. So far, there is only limited information about CPPs that mediate PNA uptake by Gram-positive bacteria. Here, we describe two methods to identify suitable CPP-antisense PNA conjugates, novel carrier molecules, and efficient target genes for streptococcal species and to evaluate their antimicrobial efficiency. |
