Effect of indomethacin on the cyclic AMP-dependent protein kinase.
Indomethacin inhibited cyclic AMP-dependent protein kinase activity in small intestine in in vivo experiments. An inverse pattern of variation was exhibited by acetyl salicylic acid, eterylate and benorylate, acetyl-p-amino-phenol being inactive. Indomethacin, acetyl salicylic acid, eterylate and benorylate increased the protein kinase activity in liver, lung and heart after in vivo administration. The in vivo effect of indomethacin was confirmed by in vitro experiments with small intestine and heart protein kinases. These results support the concept that indomethacin can affect protein kinase activity in a tissue-specific way.
