Abstract

Provided is a siRNA for inhibiting HBV gene expression, including a sense strand and an antisense strand. The sense strand includes a nucleotide sequence 1, and the antisense strand includes a nucleotide sequence 2; the nucleotide sequence 1 and the nucleotide sequence 2 are at least partially reversely complementary to form a double-stranded region; the nucleotide sequence 1 and the nucleotide sequence shown in SEQ ID NO: 1 are equal in length, and no more than 3 nucleotide differences are generated; the nucleotide sequence 2 and the nucleotide sequence shown in SEQ ID NO: 2 are equal in length, and no more than 3 nucleotide differences are generated; nucleotides of the 7th, 8th, and 9th bits of the nucleotide sequence 1 and the 2nd, 6th, 14th, and 16th of the nucleotide sequence 2 are fluoro-modified nucleotides. Also provided are a pharmaceutical composition and a conjugate containing the siRNA.
