Several imidazolylpyridinemethanols and imidazolylbenzenemethanols were prepared and evaluated for an inhibitory activity against arachidonic acid-induced platelet aggregation. The result shows that the arylmethanol moiety is essential for the activity and may correspond to the 15-OH group of prostagrandin H2 (PGH2). Among the compounds tested, 4-[α-hydroxy-5-(1-imidazolyl)-2-methylbenzyl]-3, 5-dimethylbenzoic acid (XV) was found to have a potent inhibitory activity and a long duration of action. Structureactivity relationships are also discussed briefly.
