Abstract
The potential use of alpha-beta-anomeric duplex oligonucleotides to inhibit transcription factor activity by the decoy approach is investigated in this report. Indeed, several alpha-beta-anomeric heteroduplexes display a sequence-specific interaction with the p50 subunit of the transcription factor NF kappa B. Used in a decoy approach, these duplexes interact strongly enough with this transcription factor to modulate the expression of a reporter gene, under the control of NF kappa B. However, all the alpha-beta-anomeric heteroduplexes do not interact with the p50 subunit; the sequence of the chirally natural beta-anomeric strand may explain the different recognition properties of the protein. The analysis of the appropriate beta-anomeric sequences is consistent with a preferential interaction of the p50 subunit with one strand of double-stranded DNA.Entities:
