Catalog Number: 1778
Chemical Name: 6-(Phenylsulfinyl)tetrazolo[1,5-b]pyridazine
Biological Activity
Inhibitor of NF-κB activation, possibly via selective inhibition of LPS- and TNF-α-induced IκBα ubiquitination (IC50 = 3 μM). Blocks subsequent production of TNF-α, IL-1β and IL-6. Inhibits mucin production in an in vitro model of COPD, and is anti-inflammatory following oral administration in vivo. Also weakly inhibits EGFR, 5-lipoxygenase and iNOS.
