Ibuprofen, an inhibitor of prostaglandin synthesis in eukaryotic cells, was shown to inhibit the accumulation of 3′,5′-cyclic adenosine monophosphate (cyclic AMP) in Chinese hamster ovary (CHO) cells exposed to cholera toxin. The inhibition was dose dependent, with a dose of 100 μg/ml reducing the cholera toxin response by approximately 50%, and maximal inhibition was observed when the drug was applied to the cells simulataneously with or 1 h before the toxin. Although ibuprofen also inhibited adenylate cyclase stimulation by forskolin, suggesting a nonspecific effect, the drug had no effect on cholera toxin-induced cyclic AMP accumulation when added to the culture medium 15 min or more after the toxin.
