Synthesis and inhibitory effects of 1,2,4-triazole derivatives on platelet aggregation.

Various derivatives of triazole substituted in the 2-position were prepared, and their activity on platelet aggregation tested. Compounds 4 and 14 had the most powerful action. These agents were thought to inhibit platelet aggregation via an inhibition of the cyclo-oxygenase-peroxidase complex (PGS complex), preventing synthesis of prostaglandins.
