DNA probes for the studies of damaged strand excision during the nucleotide excision repair (NER) have been designed using the novel non-nucleosidic phosphoramidite reagents that contain N-[6-(9-antracenylcarbamoyl)hexanoyl]-3-amino-1,2-propandiol (nAnt) and N-[6-(5(6)-fluoresceinylcarbamoyl)hexanoyl]-3-amino-1,2-propandiol (nFlu) moieties. New lesion-imitating adducts being inserted into DNA show

Commercially available 'fast-deprotecting' phosphoramidites are useful for synthesizing oligonucleotides containing alkali-sensitive nucleotides. However, N-acetylated oligonucleotides were observed during solid-phase synthesis using 'fast-deprotecting' phosphoramidites in conjunction with K2CO3/MeOH ('ultra-mild') deprotection. Transamidation was localized at deoxyguanosine, which is protected as its isopropylphenoxyacetyl

According to the concept presented, esters forming an amide (peptide) bond by the mechanism SN#DN or SN#*DN involving fast decay of the tetrahedral intermediate may behave as 'superactive acylating reagents'. These should render coupling involving less reactive substrates, i.e. sterically
