Patent
CA 2466773
The invention concerns a double-stranded oligonucleotide characterized in that it consists of two complementary oligonucleotide sequences forming a hybrid comprising each at one of their 3' or 5' ends one to five non-matched nucleotides forming single-stranded ends overlapping from the hybrid, one of said oligonucleotide sequences being substantially complementary of a target sequence belonging to a DNA or RNA molecule to be specifically repressed. The invention also concerns the use of said oligonucleotides in pharmaceutical compositions for treating cancers.
L'invention a pour objet un oligonucléotide double brin caractérisé en ce qu'il est constitué de deux séquences oligonucléotidiques complémentaires formant un hybride comprenant chacune à l'une de leurs extrémités 3' ou 5' un à cinq nucléotides non appariés formant des bouts simples brins débordant de l'hybride, l'une desdites séquences oligonucléotidiques étant substantiellement complémentaire d'une séquence cible appartenant à une molécule d'ADN ou d'ARN à réprimer spécifiquement. L'invention se rapporte aussi à l'utilisation desdits oligonucléotides dans des compositions pharmaceutiques notamment pour le traitement des cancers.
