cis-olefin moiety of 3 into various ring systems was examined. Incorporation of the cis-olefin of 3 into either an oxazole (26) or an unsubstituted pyrazole (35) heterocycle provided compounds that are equipotent with progenitor 3. However, the oxazole 11f, which is isomeric with 26, inhibits ADP-induced human platelet aggregation in vitro with an IC50 of 0.027 microM, 6-fold more potent than 3, 26, or
