NF-κB p65 subunit (RelA) DNA-binding inhibitor that effectively blocks influenza virus propagation both in cultures and in mice in vivo.
SC75741 (4SC-301; V1810) is a potent NF-kappaB (NF-κB) inhibitor (IC50 = 200 nM against 10 ng/mL TNF-α-induced NF-κB reporter gene expression in A549 cells) that impairs p65 subunit (RelA) DNA-binding activity without affecting p65 phosphorylation or nuclear translocation, nor proteasome-mediated IκBα degradation. SC75741 induces apoptosis in multiple myeloma cultures (IC50 from 5 to 12 μM in 48 hrs; OPM2, U266, NCI-H929, RPMI-8226), but not PBMCs (89% viability post 4-hr 100 μM SC75741 treatment). NF-κB inhibition by SC75741 treatment is reported to effectively block influenza virus propagation both in cultures in vitro (1-5 μM) and in mice in vivo (5 mg/kg daily i.v. or 7.5-15 mg/kg twice a day i.p.).
The appearance of pandemic H1N1 and highly pathogenic avian H5N1 viruses in humans as well as the emergence of seasonal H1N1 variants resistant against neuraminidase inhibitors highlight the urgent need for new and amply available antiviral drugs. We and others
A novel class of NF-kappaB pathway signaling inhibitors was discovered by virtual screening, medicinal chemistry, and QSAR analysis. An initial set of compounds inhibited NF-kappaB signaling in a whole cell reporter gene assay in the micro-molar range. Activity was improved
Ongoing human infections with highly pathogenic avian H5N1 viruses and the emergence of the pandemic swine-origin influenza viruses (IV) highlight the permanent threat elicited by these pathogens. Occurrence of resistant seasonal and pandemic strains against the currently licensed antiviral medications

Hydrogen sulfide (H2S) was revealed to inhibit aortic valve calcification and inflammation was implicated in the pathogenesis of calcific aortic valve disease (CAVD). We investigate whether H2S inhibits mineralization via abolishing inflammation. Expression of pro-inflammatory cytokines, interleukin-1β (IL-1β) and tumor
