Synthesis of new substituted azetidinoyl and thiazolidinoyl-1,3,4-thiadiazino (6,5-b) indoles as promising anti-inflammatory agents.

摘要

Various N-({5-[(arylmethylene)amino]-1,3,4-thiadiazol-2-yl}methyl) [1,3,4] thiadiazino[6,5-b]indol-3-amine (6a-6h), 2-aryl-3-{5-[([1,3,4] thiadiazino[6,5-b]indol-3-ylamino)methyl]-1,3,4-thiadiazol-2-yl}-1,3-thiazolidin- 4-one (7a-7h), and 3-chloro-4-aryl-1-{5-[{[1,3,4]thiadiazino[6,5-b]indol-3-ylamino]methyl]-1,3,4-thi adiazol-2-yl}azetidin-2-one (8a-8h) have been synthesized in the present study. The structure of these newly synthesized compounds were confirmed by their analytical and spectral data. These compounds were also evaluated for their anti-inflammatory, ulcerogenic and analgesic activities. Compound 8g has shown most active anti-inflammatory and analgesic activities with better ulcerogenic activity than phenylbutazone, while this compound was found to be associated with lesser degree of anti-inflammatory and analgesic activities as compared to indomethacin.
