Targeting RNA by the Antisense Approach and a Close Look at RNA Cleavage Reaction

This thesis summarizes the results of studies on two aspects of nucleic acids. Chemically modified antisense oligonucleotides (AONs) have been evaluated with regards to their suitability for mRNA targeting in an antisense approach (Paper I – III). The chemically modified nucleotidic units 2'-O-Me-T, 2'-O-MOE-T, oxetane-T, LNA-T, azetidine-T, aza-ENA-T, carbocy…
