| Description |
The peroxidase activity of the mitochondrial fraction of rat gastric mucosa was inhibited with various nonsteroidal
anti-inflammatory drugs (NSAIDs) in vitro. Indomethacin was found to be more effective than phenylbutazone (PB) or
acetylsalicylic acid (ASA). Mouse gastric peroxidase was also very sensitive to indomethacin inhibition. Indomethacin
has no significant effect on submaxillary gland peroxidase activity of either of the species studied. Purified rat gastric
peroxidase activity was inhibited 75% with 0.15 mM indomethacin showing half-maximal inhibition at 0.04 mM. The
inhibition could be withdrawn by increasing the concentration of iodide but not by H202. NSAIDs inhibit gastric
peroxidase activity more effectively at acid pH (pH 5.2) than at neutral pH. Spectral studies showed a bathochromic
shift of the Soret band of the enzyme with indomethacin indicating its interaction at or near the heme part of the
enzyme.
