    Abstract:
    A group of ethyl 2-methylimidazo[1,2-b]pyridazine-3-carboxylates were prepared by reaction in anhydrous ethanol of some substituted 3-amino-pyridazines with ethyl 2-chloroacetoacetate. The corresponding carboxylic acids were obtained via alkaline or acid hydrolysis and then tested both in vivo to evaluate their antiinflammatory, analgesic and ulcerogenic actions and in vitro for their ability to inhibit the prostaglandin biosynthesis. The pharmacological results are discussed in terms of both structure-activity relationships and mechanism of action.
