Pyrazofurin is a pyrimidine nucleoside analogue, inhibits cell proliferation and DNA synthesis in cells by inhibiting UMP synthase. Pyrazofurin is a sensitive orotate-phosphoribosyltransferase inhibitor (IC50s between 0.06-0.37 µM in the cell lines Hep-2,
Selenazofurin is an antiviral compound. Selenazofurin inhibits the cytopathic effect and yield of influenza A NWS 33 virus with 50% effective dose ranges of 0.7 to 1.4 micrograms ml.
Dibefurin is a metabolite that inhibits the activity of calcineurin, a calcium calmodulin-dependent protein phosphatase involved in the activation of T lymphocytes.
MI-1851 is a potent peptidomimetic inhibitor. MI-1851could prevent proteolytic processing of the S protein from SARSCoV-2 by endogenous furin in HEK293 cells.
Subtilisin/Kex2p-like proprotein convertase inhibitor; blocks activity of all seven convertases (PC1, PC2, PC4, PACE4, PC5, PC7 and furin). Abolishes proET-1 processing in endothelial cells; inhibits regulated secretion of the neuronal polypeptide VGF in
IN-2-LF, an inhibitor of lethal factor, also demonstrates inhibitory activity against furin, possessing an IC50 of 2 μM. Moreover, when used alongside D6R [1], IN-2-LF significantly enhances protection from anthrax lethal toxin.
