RNase T1 mimicking artificial ribonuclease [PDF]
Recently, artificial ribonucleases (aRNases)--conjugates of oligodeoxyribonucleotides and peptide (LR)(4)-G-amide--were designed and assessed in terms of the activity and specificity of RNA cleavage. The conjugates were shown to cleave RNA at Pyr-A and G-X sequences. Variations of oligonucleotide length and sequence, peptide and linker structure led to

Enhanced RNA cleavage within bulge-loops by an artificial ribonuclease. [PDF]
Cleavage of phosphodiester bonds by small ribonuclease mimics within different bulge-loops of RNA was investigated. Bulge-loops of different size (1-7 nt) and sequence composition were formed in a 3' terminal fragment of influenza virus M2 RNA (96 nt) by hybridization of complementary oligodeoxynucleotides. Small bulges (up to 4 nt) were readily formed

Anticancer Activity of Reconstituted Ribonuclease S‐Decorated Artificial Viral Capsid
AbstractRibonuclease S (RNase S) is an enzyme that exhibits anticancer activity by degrading RNAs within cancer cells; however, the cellular uptake efficiency is low due to its small molecular size. Here we generated RNase S‐decorated artificial viral capsids with a size of 70–170 nm by self‐assembly of the β‐annulus‐S‐peptide followed by ...

Organomercury oligonucleotide conjugates as artificial ribonucleases
Two oligonucleotide conjugates sharing the same sequence but incorporating a different 5'-terminal organometallic moiety were synthesized, by either direct mercuration in solution or oximation with an organomercury aldehyde on solid support. The potential of these conjugates to serve as new type of artificial ribonucleases was tested with a ...

Development of Site-specific Artificial Ribonucleases [PDF]
Recently we found that an antisense 2'-O-methyloligonucleotide, with two terpyridine*Cu(II) complexes at contiguous internal sites, was highly active as a site-specific (sequence-specific) artificial ribonuclease, with the activity derived from the cooperative action of the complexes.

Site-selective artificial ribonuclease using pinpoint RNA activation [PDF]
An acridine residue attached to the end or the inside of a DNA activates the target phosphodiester linkages in complementary RNA. Due to this pinpoint activation, the RNA is site-selectively and efficiently cleaved at these linkages by various free metal ions under mild condition.

Design and Synthesis of Peptide-Oligonucleotide Conjugates as Potential Artificial Ribonucleases [PDF]
A series of peptide-oligonucleotide conjugates was synthesized. The peptide fragment was attached to the middle part of DNA sequence. For this purpose the new amidophosphite dC with linker at C5-position was synthesized.

Chemically modified oligonucleotides serve as tools in fundamental research as diagnostic reagents and pharmaceutical compounds. Various chemical groups can nowadays be linked to oligonucleotides, In particular, synthetic constructs of oligonucleotides and lanthanide complexes can serve as artificial ribonucleases.

Towards artificial ribonucleases: the sequence-specific cleavage of RNA in a duplex [PDF]
Lanthanide complexes covalently attached to oligonucleotides have been shown to cleave RNA in a sequence-specific manner. Efficient cleavage, however, is at present limited to single-stranded RNA regions, as RNA in a duplex is considerably more resistant to strand scission.
