ABSTRACT
A series of imidazo[1,2-b]pyridazine-2-carboxylic acids, esters and amides was synthesized and tested for antiinflammatory, analgesic and ulcerogenic activities. The ethyl esters were prepared by cyclocondensation of some 3-aminopyridazines with ethyl bromopyruvate, followed by hydrolysis or ammonolysis in order to obtain the corresponding acids and amides. The inhibitory activity on the carrageenan-induced edema in the rat paw and on writhes induced by acetic acid in mice was evaluated, as well as the ulcerogenic action on the rat gastric mucosa. The pharmacological activity was discussed in terms of structure-activity relationships. In particular, the analgestic activity shown by these carboxylic derivatives was compared with that found in other series of imidazo[1,2-b]pyridazine analogues previously examined.
