Cyanuryl-PNA Monomer: Synthesis and Crystal Structure
摘要:
The chemical synthesis and crystal structure of the peptide nucleic acid (PNA) monomer 11 having cyanuric acid as the nucleobase is reported. The crystal structure of 11 shows molecular tapes arising from continuous intermolecular dimeric hydrogen bonding, with successive tapes held by single hydrogen bonds in the backbone.
A semi-rational approach to detect low affinity binding to noncanonical pair (NCP) sites in duplexDNA and RNA has been developed. A set of fluorogenic thiazole orange probes bearing abiotic (triazines, pyrimidines) and native RNA bases was screened against dsDNAs and dsRNAs with single abasic, single NCP and tandem NCP sites. Fluorogenic probe engagement revealed novel and selective base interactions

Disclosed herein are bifacial peptide nucleic acid probes. These probes can include a triplex hybrid forming moiety (e.g., a plurality of binding motifs disposed along a peptidyl backbone) conjugated to a prosthetic group. The triplex hybrid forming moiety can bind to a non-canonical base pairing site in a target nucleic acid via triplex hybridization. In this way, a variety of prosthetic groups (e.g., dyes, labels, reactive groups, etc.) can be selectively delivered to a target nucleic acid (e.g.,in vivo,in vitro, orex vivo).
