ChemInform Abstract: Synthesis and Pharmacological Evaluation of 1-Methyl-5- [substituted-4(3H)-oxo-1,2,3-benzotriazin-3-yl]-1H-pyrazole-4-acetic Aci…

Abstract Several new 1-methyl-5-[substituted-4-oxo-1,2,3-benzotriazin-3-yl]-1H-pyrazole-4-acetic acids and their ethyl ester derivatives were prepared. The compounds were tested for analgesic and antiinflammatory activities, acute toxicity, ulcerogenic effect, and as in vitro inhibitors of 3α-hydroxysteroid dehydrogenase (3α-HSD), since it is claimed that the inhibition of such an enzyme predicts in vivo antiinflammatory activity. Some compounds were more active than phenylbutazone in the phenylbenzoquinone and acetic acid peritonitis tests, and equiactive to the same drug in the carrageenin paw edema test. All the compounds inhibited the 3α-HSD, but no correlation was observed with the paw…
