miR-122 Inhibitor, NSC5476

A cell-permeable trans-decahydroquinolinylsulfonamide compound that acts as a potent, selective, and reversible inhibitor of miR-122 (EC₅₀ = 600 nM in Huh7 cells transfected with psiCHECK-miR122 reporter plasmid). Induces a 1,250% increase in the relative luciferase signal that is indicative of strong miRNA-122 inhibition. Displays very little activity towards miR-21. Shown to down regulate the levels of mature miR-122 (by 72%) and the primary miR-122 (down to 3%). Shown to reduce hepatitis C virus (HCV) replication in Huh7 cells (47% reduction at 10 µM).

Please note that the molecular weight for this compound is batch-specific due to variable water content. Please refer to the vial label or the certificate of analysis for the batch-specific molecular weight. The molecular weight provided represents the baseline molecular weight without water.

A cell-permeable trans-decahydroquinolinylsulfonamide compound that downregulates the liver-specific microRNA miR-122 level and pri-miR-122 production in Huh7 cells (by 72% & 93%, respectively; 10 µM for 48 h) without interaction with pre-miR-123 or affecting cellular miR-21 level. Selectively prevents miR-122-, but not miR-21-, mediated reporter transcription blockage (10 µM for 48 h) and suppresses HCV replication (by 53%; 10 µM inhibitor added 4 h post H77c/H77c/QR/KR/FV/SI RNA transfection for 48 h) in Huh7 cultures without affecting Huh7 proliferation.
