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.
Coenzyme A-independent transacylase is required for the release of free arachidonic acid, and the production of arachidonic acid metabolites and platelet activation factor. Blocking of this enzyme inhibits the production of these inflammatory mediators and will be of therapeutic utility in a broad range of allergic and inflammatory diseases and disorders. Compounds are described herein which inhibit the action of CoA-IT and are therefore useful in the treatment of disease states caused thereby.
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.
