    摘要: A pharmaceutical composition comprising a capped oligonucleotide capable of binding to a PB2 protein of an influenza virus RNA polymerase, and a pharmaceutically acceptable carrier or dilute, said capped oligonucleotide having a structure of the formula (I): m7GpppXpY  (I) wherein ppp is a triphosphate bridge, p is a monophosphate bridge, m7G is 7-methylguanosine group binding at 5′ end thereof to said ppp, X is a 2′-O-methyl guanosine group or guanosine group, said 2′-O-methyl guanosine group or guanosine group binds at a 5′ end thereof to said ppp, and at a 3′ end thereof to said p, and Y is an oligoribonucleotide moiety binding at 5′ end thereof to said p, and having 5 to 11 bases is disclosed. The pharmaceutical composition can inhibit a protein expression of an influenza virus.
