Product Description
Dual inhibitor of cyclooxygenase (COX) and 5-lipoxygenase. Also inhibits glutathione S-transferase, induction of nitric oxide (NO) in activated macrophages and inhibits EGF-induced tyrosine phosphorylation of EGF receptors. Antioxidant. Inhibitor of NAD(P)H:quinone oxidoreductase 1 (NQO1), disrupting the binding of NQO1 to wild type p53 inducing ubiquitin-independent degradation of p53 and inhibits p53-mediated apoptosis in normal thymocytes and myeloid leukemic cells.
