Abstract

The metabolites and degradation products of 2-amino-7-isopropyl-5-oxo-5H-[1] benzopyrano-[2, 3-b] pyridine-3-carboxylic acid (Amoxanox, AA-673, 1), a promising drug for the treatment of bronchial asthma, were synthesized to confirm the proposed structures and to determine their activity in the rat passive cutaneous anaphylaxis test.
