The anti-inflammatory actions of salicylates cannot be explained by inhibition of cyclooxygenase (COX) activity. This study demonstrates that sodium salicylate at a therapeutic concentration suppressed COX-2 gene transcription induced by phorbol 12-myristate 13-acetate and interleukin 1β by inhibiting the binding of CCAAT/enhancer-binding protein β to its promoter region of COX-2. By contrast, salicylate did not inhibit nuclear factor κB-dependent COX-2 induction by tumor necrosis factor α. The inhibitory effect of sodium salicylate was restricted to serum-deprived quiescent cells. These findings indicate that contrary to the current view that salicylate acts via inhibition of nuclear factor κB the pharmacological actions of aspirin and salicylates are mediated by inhibiting CCAAT/enhancer-binding protein β binding and transactivation. These findings have a major impact on the conceptual understanding of the mechanism of action of salicylates and on new drug discovery and design.
