  Synthesis and pharmacological study of ethyl 1-methyl-5-[2-substituted-4-oxo-3(4H)-quinazolinyl]-1H-pyrazole-4-acetates

  摘要：

  A number of new ethyl 1-methyl-5-[4-oxo-3(4H)-quinazolinyl]-1H-pyrazole-4-acetates substituted at the 2 position of the quinazolinone ring were prepared. The compounds were tested for analgesic and antiinflammatory activities, as well as for their acute toxicity and ulcerogenic effect. The 2-methyl, 2-ethyl and 2-phenyl derivatives proved to be more active than acetylsalicylic acid and phenylbutazone in the phenylbenzoquinone writhing test. The 2-methyl derivative was also as active as acetylsalicylic acid in the carrageenin paw oedema test. All the compounds showed very reduced ulcerogenic effects and systemic toxicity.

  Several new 1-methyl-5-[substituted-dioxo-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 3 alpha-hydroxysteroid dehydrogenase (3 alpha-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 3 alpha-HSD, but no correlation was observed with the paw edema inhibition values. The compounds proved to possess marginal or no ulcerogenic effect as well as low systemic toxicity. (C) 1998 Elsevier Science S.A. All rights reserved.
