Miravirsen (SPC-3649), a β-d-oxy-locked nucleic acid-modified phosphorothioate antisense oligonucleotide, inhibit the biogenesis of miR-122. Miravirsen (SPC-3649) is used in the study for HCV infections.

miR-21 inhibitor 12 (miR-21-IN-12) is a small molecule inhibitor of microRNA-21 expression and inhibit miR-21 transcription.miR-21-IN-12 inhibited transcription of the miR-21 gene resulting in significant reductions in primary and mature miR-21 levels.miR-21-IN-12 demonstrated cytotoxicity in a cervical cancer cell line via induction of apoptosis and was capable of reducing microtumor formation in a long-term clonogenic assay.miR-21-IN-12 shows some level of selectivity for miR-21 and is not a general miRNA pathway inhibitor.

TGP-29b-066 (Targapremir-29b-066) is a specfic small-molecule miR-29b inhibitor that targets miR29b hairpin precursor (pre-miR-29b), selectivity and effectively decreases miR-29b expression levels in C2C12 myoblast, attenuates muscle atrophy in vitro and

Targapremir-200c (TGP-200c) is a structure-specific, small molecule inhibitor of miR-200c precursor (pre-miR-200c), binds to the Dicer site of pre-miR-200c with Kd of 50 nM.TGP-200c inhibits Dicer processing of pre-miR-200c with IC50 320 nM, selectively engages pre-miR-200c in cells.TGP-200c potently inhibits miR-200c biogenesis selectively across the miRnome and modulates the downstream miR-200c pathway.TGP-200c selectively inhibits miR-200c over other miR-200 family members by recognizing the 1x1 UU internal loop unique to pre-miR-200c and an adjacent AU base pair simultaneously.TGP-200c selectively rescues a miR-200c-mediated phenotype in MIN6 cells, induces anti-apoptotic phenotype, modulates various T2D-related pathways, including insulin signaling and metabolism, represses pro-cell death factors and promotes β cell survival in specific ways.

MTL-CEPBA is a small activating RNA targeting for upregulation of C/EBPα. MTL-CEPBA has anti-inflammatory and anti-cancer activity.

Lademirsen (SAR339375; RG-012) is a highly specific antisense oligonucleotide (ASO) targeting miR-21. Lademirsen has the potential for Alport nephropathy research.

RG-101 is a hepatocyte targeted N-acetylgalactosamine conjugated oligonucleotide that antagonises miR-122. miR-122 is an important host factor for hepatitis C virus (HCV) replication.

Targaprimir-96 TFA is a potent inhibitor of microRNA-96 (miR-96) processing. Targaprimir-96 TFA selectively modulates miR-96 production in cancer cells and triggers apoptosis. Targaprimir-96 TFA binds primary miR-96 (pri-miR-96) with low nanomolar affinity. Targaprimir-96 TFA directly engages pri-miR-96 in breast cancer cells and is ineffective on healthy breast cells.

Targaprimir-96 is a potent inhibitor of microRNA-96 (miR-96) processing. Targaprimir-96 selectively modulates miR-96 production in cancer cells and triggers apoptosis. Targaprimir-96 binds primary miR-96 (pri-miR-96) with low nanomolar affinity. Targaprimir-96 directly engages pri-miR-96 in breast cancer cells and is ineffective on healthy breast cells.

miR-21 inhibitor 37 is a novel inhibitor of miR-21 function with EC50 of 5.3 uM in HeLa-miR21-Luc assays, displays no inhibition of miR-122.
