Studies on anti-inflammatory, analgesic and antipyretic activities of some indan acids.

A series of indan-1 acids were synthesized and screened for anti-inflammatory activity. All the reported compounds showed varying degrees of anti-inflammatory activity in carrageenin-induced paw oedema test. They also exhibited appreciable antipyretic and analgesic activity in various animal test models. Among these compounds 6-methoxy-indan-1-acetic acid (compound 11) and 5,6-dimethoxy-indan-1-acetic acid (compound 12) showed activity profile close to that of phenylbutazone having prolonged action and lower toxicity than the latter.
