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.
一系列新颖的噁唑衍生物,具有以下式I和II##STR1##其中R为H或C.sub.1-C.sub.5较低烷基,X为N或CH,Y为H或CO.sub.2R.sup.1,或CO.R.sup.2,但当X为CH时,Y不是H,R.sup.1为C.sub.1-C.sub.5较低烷基,或苄基甲基,R.sup.2为C.sub.1-C.sub.5烷基;##STR2##其中R为H或C.sub.1-C.sub.5较低烷基,X为(CH.sub.2).sub.n或对位或间位取代的苯基,其中取代基为OR.sup.2,R.sup.2为C.sub.1-C.sub.5烷基,n为4至8的整数,或其药用盐。这些化合物可用作抑制ADP诱导的人类富含血小板血浆中的血小板聚集。
