MicroRNA

Cl-amidine hydrochloride is an orally available PAD inhibitor that blocks histone 3 deimination and neutrophil extracellular trap formation and improves survival in septic mice. It induces apoptosis in cancer cells and induces miR-16 to cause cell cycle arrest.

Lin28 1632 is an inhibitor of RNA binding protein Lin28. It promotes mESC differentiation. Lin281632 is also bromodomain inhibitor.

Camptothecin (CPT) belongs to the alkaloid group of natural products and is a specific DNA topoisomerase I (Topo I) inhibitor (IC50=679 nM) with specificity. Camptothecin has antitumor activity and induces apoptosis.

TGP-377 421 (Targapre-miR-377 421) is a potent dual inhibitor that binds to and inhibits miR-377 and miR-421 at their functional sites.

Rubone (2'-Hydroxy-2,4,4',5,6'-pentamethoxychalcone), a natural product and a modulator of miR-34a (microRNA-34), upregulates miR-34a expression in a p53-dependent manner, which in turn downregulates the expression of downstream targets Bcl-2, cyclin-D1, CDK6, SIRT1, and FOXP1, thereby inhibiting tumor growth and reversal of hepatocellular carcinoma (HCC) and chemoresistance in prostate cancer.

PIN1 inhibitor API-1 is a specific Pin1 inhibitor (IC50: 72.3 nM) that retains the active conformation of pXPO5, restoring its ability to transport pre-miRNAs from the nucleus to the cytoplasm, thereby up-regulating anticancer miRNA biogenesis to suppress hepatocellular carcinoma development both in vitro and in vivo. PIN1 inhibitor API-1 directly and specifically binds to the Pin1 peptidyl-prolyl isomerase domain, effectively inhibiting Pin1 cis-trans isomerizing activity.

Aurintricarboxylic acid (NSC-4056) is a strong inhibitor of topoisomerases and other nucleases. It is a potent inhibitor of ribonuclease and topoisomerase II by preventing the binding of the nucleic acid to the enzyme.

LIN28 inhibitor LI71 is a potent and cell-permeable compound that effectively abolishes LIN28-mediated oligouridylation, with an IC50 of 7 µM (micromolar).

1. Pseudoprotodioscin has moderate cytotoxicity.

Enoxacin hydrate (AT-2266 hydrate) is a broad-spectrum 6-fluoronaphthyridinone antibacterial agent.

Enoxacin (NSC-629661) is a broad-spectrum 6-fluoronaphthyridinone antibacterial agent (fluoroquinolones) structurally related to nalidixic acid.

Lin28-let-7a antagonist 1, with an IC50 of 4.03 μM for Lin28A-let-7a-1 interaction,and shows a clear antagonistic effect against the Lin28-let-7a interaction.

MicroRNA-21-IN-2 is a potential miR-21 inhibitor with an AC50 value of 3.29 μM. MicroRNA-21-IN-2 can be used to study cancer.
