Studies on an anti-inflammatory agent. III. Pharmacological investigations of a new non-steroidal anti-inflammatory agent: 2-oxo-3-[4-(1-oxo-2-isoindolinyl)-phenyl]-butanamide (GP 650).
The anti-inflammatory, analgesic, antipyretic and ulcerogenic activities and acute toxicity of 2-oxo-3-[4-(1-oxo-2-isoindolinyl)-phenyl]-butanamide (GP 650) were investigated in laboratory animals and compared with those of phenylbutazone, acetylsalicylic acid (ASA), ibuprofen, tiaramide-HCl and tinoridine-HCl. The anti-inflammatory and analgesic activities of GP 650 were found to be almost equivalent to those of phenylbutazone on the basis of various anti-inflammatory and analgesic tests while its antipyretic activity was less marked, and its ulcerogenic action and acute toxicity were much lower than those of the other agents. It is interesting to note that GP 650 possesses marked anti-inflammatory activity similar to acidic anti-inflammatory agents in chronic inflammatory models along with mild antipyretic and ulcerogenic activities found in basic anti-inflammatory agents. Therefore, GP 650 appears to be a promising anti-inflammatory and analgesic agent.
