Patent

CA 2168409

The invention relates to oligonucleotides of the formula 5' - (CAP) - (Oligo) - (CAP) -3' where (Oligo) is a nucleotide sequence of from 10 to 40 nucleotides in length, and CAP is G m, where m is an integer of from zero to ten, preferably of from two to six, particularly preferably of from three to five and very particularly preferably four, and where the two CAP's which are present in the molecule can be defined independently of each other and must be different in the case where m is zero at the 5' or 3' end and the end of the "Oligo" sequence is not formed by a guanine, to a process for their preparation, to pharmaceuticals con- taining the novel oligonucleotides, and to their use for preparing a pharmaceutical for treating diseases or for preparing a diagnostic agent.

La présente invention a pour objet des oligonucléotides de formule 5'-(CAP)-(oligo)-(CAP)-3' dans lesquels (oligo) est une séquence nucléotide de 10 à 40 nucléotides, CAP est Gm, dans lequel m est un entier compris entre 0 et 10, préférablement de 2 à 6, plus préférablement de 3 à 5, et encore plus préférablement 4, et dans lesquels les deux CAP présents dans la molécule peuvent être définis indépendamment l'un de l'autre et doivent être différents lorsque m est égal à 0 à l'extrémité 5' ou 3' et que l'extrémité de la séquence « oligo » n'est pas formée de la guanine. La présente invention au aussi pour objet un procédé pour leur préparation, des médicaments contenant les nouveaux oligonucléotides, et leur utilisation dans la préparation d'un médicament pour le traitement de maladies ou pour la préparation d'un agent diagnostique.
