Five acidic phenyl derivatives of the imidazo[1,2-b]pyridazine system were subjected to some tests in vivo in order to evaluate their biological activity. Antiinflammatory activity was studied by means of the carrageenin rat paw edema, whereas writhing induced in mice by acetic acid was used to assess analgesic activity. The irritative and ulcerogenic action on the rat gastric mucosa was examined after oral administration of larger doses. The inhibitory activity on platelet malondialdehyde production was studied in vitro. The experimental results are discussed from the point of view of structure-activity relationships and mode of action.
