Description

General description

A cell-permeable tetrazolopyridazine-phenylsulfoxide compound that displays anti-inflammatory properties. Acts as a highly selective, irreversible inhibitor of IκBαee ubiquitination (IC₅₀ = 2.3 µM). Also reported to prevent degradation of IκBαee in MM6 cells (complete inhibition at ~3-5 µM). Shown to block NF-κB-dependent cytokine expression in human peripheral blood mononuclear cells (PBMN) (IC₅₀ = 600-700 nM for TNF-α, IL-1β, and IL-6 inhibition). Also shown to lower circulating levels of TNFα in LPS-treated rats. Also shown to inhibit 5-lipoxygenase (89% inhibition) and EGFR kinase (63% inhibition) at higher concentrations (10 µM).

A cell-permeable tetrazolopyridazine-phenylsulfoxide compound that displays anti-inflammatory properties. Acts as a highly selective, irreversible inhibitor of IκBαee ubiquitination (IC₅₀ = 2.3 µM). Blocks NF-κB-dependent cytokine expression in human PBMNs (IC₅₀’s = ~ 700 nM for TNF-α, IL-1β, and IL-6 inhibition) and rats. Does not inhibit SCF^βTRCP(IκBα ubiquitin ligase)-mediated β-catenin ubiquitination in Jurkat cells. At 10 µM concentrations, also inhibits the activities of 5-lipoxygenase (by 89%) and EGFR kinase (by 63%).
