生物活性:
Miravirsen (SPC-3649) is a potent miR-122 inhibitor and inhibits the biogenesis of miR-122. Miravirsen is a 15-nucleotide locked nucleic acid-modified phosphorothioate antisense oligonucleotide. Miravirsen inhibits HCV replication. Miravirsen can be used in research of HCV infection.

体内研究:
Miravirsen (SPC-3649; 2.5-25 mg/kg; i.v.; daily, for 3 d) inhibits miR-122 activity in mice.Animal Model:NMRI female mice (27 g)
Dosage:2.5, 6.25, 12.5, and 25 mg/kg
Administration:Intravenous injection; daily, for 3 days
Result:Inhibited miR-122 activity in a dose-dependent manner.

体外研究:
Miravirsen is thought to work mainly by hybridizing to mature miR-122 and blocking its interaction with HCV RNA, its target sequence is also present in pri- and pre-miR-122. Miravirsen binds to the stem-loop structure of pri- and pre-miR-122 with nanomolar affinity, and inhibits both Dicer- and Drosha-mediated processing of miR-122 precursors.
