Artificial ribonucleases inactivate a wide range of viruses using their ribonuclease, membranolytic, and chaotropic-like activities

open access: yesAntiviral Research, 2016
Artificial ribonucleases (aRNases) are small compounds catalysing RNA cleavage. Recently we demonstrated that aRNases readily inactivate various viruses in vitro. Here, for three series of aRNases (1,4-diazabicyclo [2.2.2]octane-based and peptide-like compounds) we show that apart from ribonuclease activity the aRNases display chaotropic-like and ...

An Artificial Imine Reductase based on the Ribonuclease S Scaffold

open access: yesChemCatChem, 2014
AbstractDative anchoring of a piano‐stool complex within ribonuclease S resulted in an artificial imine reductase. The catalytic performance was modulated upon variation of the coordinating amino acid residues in the S‐peptide. Binding of Cp*Ir (Cp*=C5Me5) to the native active site resulted in good conversions and moderate enantiomeric excess values ...

A METHOD FOR SYNTHESIS OF AN ARTIFICIAL RIBONUCLEASE

Nucleosides, Nucleotides and Nucleic Acids, 2001
5-Amino-2,9-dimethyl-1,10-phenanthroline-oligonucleotide conjugates have been synthesized. A 2'-O-methyl octaribonucleotide carrying a 2'-aminoethoxymethyl linker in a central position was produced. Reaction of the aminoneocuproine phenyl carbamate with the fully deprotected oligonucleotide in aqueous solution gave virtually quantitative conversion ...

SYNTHESIS AND CHARACTERIZATION OF POLYAMINE-BASED BIOMIMETIC CATALYSTS AS ARTIFICIAL RIBONUCLEASE

Nucleosides, Nucleotides and Nucleic Acids, 2001
Several polyamine derivatives (I-V) conjugated with or without an intercalative moiety were prepared as ribonuclease mimics. Although no DNA-cleaving activity was observed for all compounds tested, mimics I, III, and V bearing an intercalative moiety along with the primary amine and/or imidazole moieties exhibited potent RNA-cleaving activity at near ...

Characterization of an artificial dimer of ribonuclease H using 1H NMR spectroscopy

Journal of Biomolecular NMR, 1996
The protein fusion technique was applied in the synthesis of an artificial dimer of ribonuclease H (305 residues). 1H NMR spectroscopy was used to analyze the structure of this dimer. Spectral profiles and pKa values of the histidine residues obtained using 1H NMR indicate that the dimer retains the secondary and tertiary structures of the intact ...
