As a part of a broader structure-activity relationship study of substituted 2-aminopyrimidines, the influence of the C-5 substitution on inhibition of prostaglandin E2 (PGE2) production was studied. Thirty compounds were prepared starting from the corresponding 2-amino-4,6-dichloropyrimidines using Suzuki cross-coupling. It was shown previously that 2-amino-4,6-dichloropyrimidines with smaller C-5 substituent (hydrogen and methyl) were devoid of significant activity, while 5-Bu derivatives exhibited prominent potency. In this study, on the other hand, both monoaryl- and bisarylpyrimidines were potent inhibitors of PGE2 production regardless the length of the C-5 substituent (hydrogen, Me, n-butyl). Moreover, the shorter the C-5 substituent the higher potency to inhibit PGE2 production was observed 2-Amino-4,6-diphenylpyrimidine was the best inhibitor of PGE2 production with IC50 = 3 nM and no cytotoxicity. The most potent inhibitors deserve further preclin. evaluation as potential anti-inflammatory agents.
