A series of chalcone analogues was synthesized and used as precursor for the synthesis of novel series of pyrimidines. Both groups have been evaluated for their effects on the cyclooxygenases (COXs) that are imperative enzymes in the genesis of prostaglandin H2, which is an antecedent for the biosynthesis of prostaglandins, thromboxanes and prostacyclins. The results depicted that chalcones and pyrimidines are very active inhibitors according to the pattern of substitution. Compounds C4, C5, P4 and P5 with methoxylation and nitro substitutions showed best results to inhibit COX-2.


Key words: COX inhibitors, chalcones, pyrimidines, anti-inflammatory agents.
