A novel series of oxazole derivatives having the Formulae I and II ##STR1## wherein R is H or C.sub.1 -C.sub.5 lower alkyl, X is N or CH, Y is H or CO.sub.2 R.sup.1, or CO.R.sup.2, provided that when X is CH, Y is not H, R.sup.1 is C.sub.1 -C.sub.5 lower alkyl, or phenylmethyl, and R.sup.2 is C.sub.1 -C.sub.5 alkyl; ##STR2## wherein R is H or C.sub.1 -C.sub.5 lower alkyl, X is (CH.sub.2).sub.n or para or meta substituted phenyl wherein the substituent is OR.sup.2, R.sup.2 is C.sub.1 -C.sub.5 alkyl, and n is an integer of 4 to 8, or a pharmaceutically acceptable salt thereof. The compounds are useful as inhibitors of ADP-induced blood platelet aggregation in human platelet-rich plasma.
