An siRNA which inhibits kininogen (KNG) gene expression, a pharmaceutical composition containing the siRNA, and an siRNA conjugate. Each nucleotide in the siRNA is independently a modified or unmodified nucleotide. The siRNA contains a sense strand and an antisense strand. The sense strand contains nucleotide sequence I, nucleotide sequence I having the same length as the nucleotide sequence shown in SEQ ID NO: 1, with no more than three nucleotide differences. The antisense strand contains nucleotide sequence II, nucleotide sequence II having the same length as the nucleotide sequence shown in SEQ ID NO: 2, with no more than three nucleotide differences. The siRNA, the pharmaceutical composition thereof and the siRNA conjugate can effectively treat and/or prevent septicemia.
一种抑制激肽原(KNG)
基因表达的 siRNA、一种含有该 siRNA 的药物组合物以及一种 siRNA 结合物。siRNA 中的每个核苷酸都是独立的修饰或未修饰核苷酸。siRNA 包含有义链和反义链。有义链包含核苷酸序列 I,核苷酸序列 I 的长度与
SEQ ID NO: 1 所示的核苷酸序列相同,核苷酸差异不超过三个。反义链包含核苷酸序列 II,核苷酸序列 II 的长度与
SEQ ID NO: 2 所示的核苷酸序列相同,核苷酸差异不超过三个。siRNA 及其药物组合物和 siRNA 结合物可有效治疗和/或预防败血症。
