Abstract

Referida a una molecula de acido nucleico interferente corto (siNA) que comprende: (a) una cadena de sentido que comprende una primera secuencia de nucleotidos que es al menos alrededor de 60 % a 100 % identica a un ARN que corresponde a un gen diana, en donde la primera secuencia de nucleotidos: (i) tiene de 15 a 30 nucleotidos de longitud; y (ii) comprende 15 o mas nucleotidos modificados que se seleccionan independientemente de un nucleotido 2'-O-metilo y un nucleotido 2'-fluoro, en donde al menos un nucleotido modificado es un nucleotido 2'-O-metilo y el nucleotido en la posicion 3, 5, 7, 8, 9, 10, 11, 12, 14, 17 y/o 19 del extremo 5' de la primera secuencia de nucleotidos es un nucleotido 2'-fluoro; y (b) una cadena antisentido que comprende una segunda secuencia de nucleotidos que es al menos alrededor de 60 % a 100 % complementaria con respecto al ARN que corresponde al gen diana, en donde la segunda secuencia de nucleotidos: (i) tiene de 15 a 30 nucleotidos de longitud; y (ii) comprende 15 o mas nucleotidos modificados independientemente seleccionados de un nucleotido 2'-O-metilo y un nucleotido 2'-fluoro, en donde al menos un nucleotido modificado es un nucleotido 2'-O-metilo y al menos un nucleotido modificado es un nucleotido 2'-fluoro. Las moleculas de siNA pueden ser de cadena doble y comprender nucleotidos modificados que se seleccionan de nucleotidos 2'-O-metilo y nucleotidos 2'- fluoro. En la presente se describen ademas moleculas de siNA que comprenden (a) un bloqueador de fosforilacion, un resto conjugado o un casquete del extremo 5' estabilizado; y (b) un acido nucleico interferente corto (siNA).
