Abstract
Antibiotic resistance is a growing global problem, so there is an urgent need for new antimicrobial agents and strategies. Peptide nucleic acid (PNA) oligomers could be designed and utilized as gene-specific oligonucleotides to target any infectious agents. Selectivity and high-affinity binding are the main properties of PNA. However, in therapeutic applications, intracellular delivery of peptide nucleic acids is still a challenge. In photodynamic therapy (PDT), which could be a useful adjunct to mechanical and antibiotics in removing pathogenic agents, low-power lasers are used in appropriate wavelength for killing the microorganisms that have been treated with a photosensitizer drug. Antimicrobial photodynamic therapy (aPDT) in combination with lipid-charged nanoparticles of PNA is a promising alternative therapy proposed to control infectious diseases. This review summarizes progress in the uptake of peptide nucleic acids at intracellular targets. In addition, we focus on recent nanoparticle- based strategies to efficiently deliver conventional and chemically modified peptide nucleic acids. The likely impact of using two treatment methods simultaneously, i.e., PNP and PDT, has already been discussed.
期刊介绍:
Infectious Disorders - Drug Targets aims to cover all the latest and outstanding developments on the medicinal chemistry, pharmacology, molecular biology, genomics and biochemistry of contemporary molecular targets involved in infectious disorders e.g. disease specific proteins, receptors, enzymes, genes. Each issue of the journal contains a series of timely in-depth reviews written by leaders in the field covering a range of current topics on drug targets involved in infectious disorders. As the discovery, identification, characterization and validation of novel human drug targets for anti-infective drug discovery continues to grow, this journal will be essential reading for all pharmaceutical scientists involved in drug discovery and development.
