A group of seven acidic phenyl derivatives of some fused imidazole systems were subjected to a series of tests in vivo in order to evaluate their pharmacological activity. Antiinflammatory activity was studied by means of the carrageenin-induced rat paw edema. Hot plate test and writhing induced by acetic acid in mice were used to evaluate analgesic activity. Yeast-induced hyperthermia in rats was employed to study antipyretic action. Irritative and ulcerogenic action on the rat gastric mucosa was examined at higher doses. The antiaggregating activity and the inhibition of platelet malondialdehyde production were studied in vitro. All experimental results are discussed from the point of view of structure-activity relationships and mode of action.
