A group of derivatives of 7-methanesulfonylamino-6-phenoxychromone (1) at the pyrone and phenoxy rings was synthesized with 4-chloro-3-nitroanisole and evaluated against acute and chronic inflammations in oral administration in animals. Significant potency in the rat models of carrageenin-induced edema (CPE) and adjuvant-induced arthritis (AA) was realized with 2'-fluoro and 2', 4'-difluoro derivatives (9a and 9d), and 3-formylamino ...
