| Abstract: | In this study, thirty six new 2-benzylidene-7-methyl-3-oxo-5-phenyl-2,3-dihydro-5H-thiazolo3,2-a]pyrimidine-6-carboxylic acid methyl esters were synthesized and characterized by spectral, crystallographic, and elemental analysis. The antiinflammatory activity of the compounds was tested by the carrageenan hind paw edema test. It was found that compound 6a having a 2-methoxyphenyl group at position 5 and a benzylidene group at position 2 was the most potent compound in this series. All the compounds that were tested for ulcer activity gave positive results. |
