Oxazole derviatives having Formula I or II are disclosed which are useful as inhibitors of mammalian blood platelet aggregation.
Formula I and Formula XIX compounds are those wherein n is 7-9 and R is hydrogen or lower alkyl. Formula II compounds are those wherein R is hydrogen, lower alkyl or together with C02 is tetrazol-1-yl; R1 is phenyl or thienyl; X is a divalent connecting group selected from the group consisting of CH2CH2, CH = CH, and CH20; Y is a divalent connecting group attached to the 3 or 4 phenyl position selected from the group consisting of OCH2, CH2CH2 and CH=CH. Formula XX compounds are those wherein the OCH2C02R moiety is attached to the 3 or 4 phenyl position and R is hydrogen or lower alkyl.

fashion, consistent with 18b inhibiting platelet function by acting as a prostacyclin mimetic. By inserting a phenoxy ring into the side-chain moiety of 18b and systematically varying the pattern of substitution and length of the tethers, more potent inhibitors of platelet aggregation were identified. A phenoxy ring inserted centrally in the side chain proved to be the optimal arrangement but significant

Oxazole derivatives having Formula I or II are disclosed which are useful as inhibitors of mammalian blood platelet aggregation. ##STR1## Formula I and Formula XIX compounds are those wherein n is 7-9 and R is hydrogen or lower alkyl. Formula II compounds are those wherein R is hydrogen, lower alkyl or together with CO.sub.2 is tetrazol-1-yl; R.sub.1 is phenyl or thienyl; X is a divalent connecting group selected from the group consisting of CH.sub.2 CH.sub.2, CH.dbd.CH, and CH.sub.2 O; Y is a divalent connecting group attached to the 3 or 4 phenyl position selected from the group consisting of OCH.sub.2, CH.sub.2 CH.sub.2 and CH.dbd.CH. Formula XX compounds are those wherein the OCH.sub.2 CO.sub.2 R moiety is attached to the 3 or 4 phenyl position and R is hydrogen or lower alkyl.
