Abstract
Originally discovered by Nielsen in 1991, peptide nucleic acids and other artificial genetic polymers have gained a lot of interest from the scientific community. Due to their unique biophysical features these artificial hybrid polymers are now being employed in various areas of theranostics (therapy and diagnostics). The current review provides an overview of their structure, principles of rational design, and biophysical features as well as highlights the areas of their successful implementation in biology and biomedicine. Finally, the review discusses the areas of improvement that would allow their use as a new class of therapeutics in the future.

Abstract
The involvement of microRNAs in human pathologies is firmly established. Accordingly, the pharmacological modulation of microRNA activity appears to be a very interesting approach in the development of new types of drugs (miRNA therapeutics). One important research area is the possible development of miRNA therapeutics in the field of rare diseases. In this respect, appealing molecules are based on peptide nucleic acids (PNAs), displaying, in their first description, a pseudo-peptide backbone composed of N-(2-aminoethyl)glycine units, and found to be excellent candidates for antisense and antigene therapies. The aim of the present article is to describe methods for determining the activity of PNAs designed to target microRNAs involved in cystic fibrosis, using as model system miR-145-5p and its target cystic fibrosis transmembrane conductance regulator (CFTR) mRNA. The methods employed to study the effects of PNAs targeting miR-145-5p are presented here by discussing data obtained using as cellular model system the human lung epithelial Calu-3 cell line.

Antisense peptide nucleic acids as a potential anti-infective agent. J Microbiol 2019; 57:423-430. [PMID: 31054136 DOI: 10.1007/s12275-019-8635-4] [Citation(s) in RCA: 22] [Impact Index Per Article: 4.4] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/19/2018] [Revised: 01/25/2019] [Accepted: 01/28/2019] [Indexed: 01/25/2023]
Abstract
Antibiotics have long been used for anti-infective control of bacterial infections, growth promotion in husbandry, and prophylactic protection against plant pathogens. However, their inappropriate use results in the emergence and spread of multiple drug resistance (MDR) especially among various bacterial populations, which limits further administration of conventional antibiotics. Therefore, the demand for novel anti-infective approaches against MDR diseases becomes increasing in recent years. The peptide nucleic acid (PNA)-based technology has been proposed as one of novel anti-infective and/or therapeutic strategies. By definition, PNA is an artificially synthesized nucleic acid mimic structurally similar to DNA or RNA in nature and linked one another via an unnatural pseudo-peptide backbone, rendering to its stability in diverse host conditions. It can bind DNA or RNA strands complimentarily with high affinity and sequence specificity, which induces the target-specific gene silencing by inhibiting transcription and/or translation. Based on these unique properties, PNA has been widely applied for molecular diagnosis as well as considered as a potential anti-infective agent. In this review, we discuss the general features of PNAs and their application to various bacterial pathogens as new anti-infective or antimicrobial agents.

Abstract
In this report, we investigate the efficiency and selectivity of a Zn2+-dependent peptide nucleic acid-based artificial ribonuclease (PNAzyme) that cleaves RNA target sequences. The target RNAs are varied to form different sizes (3 and 4 nucleotides, nt) and sequences in the bulge formed upon binding to the PNAzyme. PNAzyme-promoted cleavage of the target RNAs was observed and variation of the substrate showed a clear dependence on the sequence and size of the bulge. For targets that form 4-nt bulges, we identified systems with an improved efficacy (an estimated half-life of ca 7–8 h as compared to 11–12 h for sequences studied earlier) as well as systems with an improved site selectivity (up to over 70% cleavage at a single site as compared to 50–60% with previous targets sequences). For targets forming 3-nt bulges, the enhancement compared to previous systems was even more pronounced. Compared to a starting point of targets forming 3-nt AAA bulges (half-lives of ca 21–24 h), we could identify target sequences that were cleaved with half-lives three times lower (ca 7–8 h), i.e., at rates similar to those found for the fastest 4-nt bulge system. In addition, with the 3-nt bulge RNA target site selectivity was improved even further to reach well over 80% cleavage at a specific site.

Abstract
Triplex-forming peptide nucleic acids (TFPNAs) were targeted to double-helical regions of 19 F-labeled RNA hairpin models (a UA-rich duplex with a hexaethylene glycol (heg) loop and a microRNA model, miR-215). In addition to conventional UV- and circular dichroism (CD)-based detection, binding was monitored by 19 F NMR spectroscopy. Detailed information on the stoichiometry and transition between the triple-helical peptide nucleic acid (PNA)/RNA and (PNA)2 /RNA binding modes could be obtained. γ-(R)-Hydroxymethyl-modified thymine-1-yl- and 2-aminopyridin-3-yl-acetyl derivatives of TFPNAs were additionally synthesized, which were targeted to the same RNA models, and the effect of the γ-(R)-hydroxymethyl group on binding was studied. An appropriate pattern of γ-(R)-hydroxymethyl modifications reduced the stability of the ternary complex and preferred stoichiometric binding to the miR-215 model.
