title: Indeno[1,2-c]pyrazolone acetic acids as semirigid analogues of the nonsteroidal anti-inflammatory drugs.
abstract: A series of 3-substituted indeno[1,2-c]pyrazol-4(1H)-one-2-acetic acids (3a-e) and 3-substituted indeno[1,2-c]pyrazol-4(1H)-one-1-acetic acids (4a-e) were synthesized as semirigid analogues of tolmetin (1). These compounds were evaluated for their anti-inflammatory action by investigating their ability to block arachidonic acid metabolism in vitro as well as the ability to block carrageenan-induced rat foot edema in vivo. No consistent pattern of biological activity was noted.
