Dibenz[b,e]oxepinalkanoic acids as nonsteroidal antiinflammatory agents. 2. Dihydro-10-oxofuro-and -thieno[3,2-c][1]benzoxepin-8-acetic acids.
4,10-Dihydro-10-oxofuro[3,2-c][1]benzoxepin-8-acetic acid and 4,10-dihydro-10-oxothieno[3,2-c][1]benzoxepin-8-acetic acid were evaluated in the carrageenan paw edema assay with the thieno analogue being ten times more active than the furano compound and 1.3. times more active than indomethacin. The therapeutic ratio (antiinflammatory activity/gastric irritation liability) of the thieno analogue was 25 times that of indomethacin.
