  • Publication number: 20240156966
    Abstract: The present invention relates to a siRNA drug, a pharmaceutical composition, a siRNA-small molecule drug conjugate, and the application thereof. The siRNA molecules block the life cycle of virus replication by targeting and inhibiting the expression of key genes for influenza viruses, reduce viral infection, and ultimately clear the viruses. The present invention provides a drug based on the siRNA. The drug can be atomized into liquid droplets through an atomizing device, and the liquid droplets reach the lower respiratory tract and the lung by inhalation, so as to inhibit the replication of the influenza viruses. The pharmaceutical composition of the present invention can exert a synergistic antiviral effect through different mechanisms of action.

  • Publication number: 20230355656
    Abstract: siRNA sequences for inhibiting TGF? and Cox-2 gene expression are provided. Methods for treatment of skin cancers, in which pharmaceutical compositions or containing these siRNA agents and complexes, are further provided, in particular, for treating squamous cell carcinoma (isSCC) and/or basal cell carcinoma (BCC). TGF? and Cox-2 have each been implicated in driving cancer progression. TGF? is upregulated in a number of tumor types and plays a role in stimulating cancer-associated fibroblast development. Cox-2 upregulation plays a negative role in inducing inflammation and converting active T-cells to inactive T-reg cells. Co-delivery of the two siRNAs into the same cell at the same time silences of both targets at the same time results in antitumoral activity.

  • Publication number: 20220331441
    Abstract: A novel nucleic acid delivery system is provided containing a linear histidine-lysine rich cysteine-containing peptide bearing a targeting function, and a four branched histidine-lysine rich polypeptide. The delivery system includes a nucleic acid, such as an siRNA. The components form a nanoparticle complex through multiple non-covalent interactions between the phosphates of siRNA and histidine/lysine of the polypeptide, with reduced toxicity. The stable complex selectively delivers the genetic material to cells. The targeting function enhances the efficiency of the nucleic acid delivery and transfection. Carrier molecules also are provided that have the ability to deliver a therapeutic molecule to a specific cell within a tissue in the body. The carrier molecule is modified with a targeting ligand capable of binding to specific receptors present or upregulated on the cell to be targeted. The therapeutic molecule is an siRNA, miRNA, or other oligonucleotide.
