The pro-drugs of α, 2-dimethyl-5H-[1] benzopyrano [2,3-b] pyridine-7-acetic acid (I) with a potent anti-inflammatory activity were synthesized in order to reduce its gastrointestinal side effects. Various esters synthesized were evaluated for their anti-inflammatory activity and ulcerogenicity. Among the compounds maintaining a potent activity of I, N, N-dimethylcarbamoyl-methyl α, 2-dimethyl-5H-[1] benzopyrano [2,3-b] pyridine-7-acetate (II-18) showed excellent biopharmaceutical characteristics. The ulcerogenic effect of II-18 showed excellent biopharmaceutical characteristics. The ulcerogenic effect of II-18 on the rat gastric mucosa was about 3 times less than that of I. It was suggested that II-18 may be an useful biolabile pro-drug for I among the compounds tested.
