Abstract: 7-Oxabicycloheptane imino interphenylene substituted prostaglandin analogs are provided having the structural formula ##STR1## wherein n is 1 or 2; m is 1 or 2; R is H, lower alkyl, or alkali metal; and R.sup.1 is --OR.sup.2, ##STR2## where R.sup.2 is lower alkyl, aryl, aralkyl, cycloalkylalkyl, alkanoyl or aroyl; and R.sup.3 is lower alkyl, aryl, aralkyl, alkoxy, aryloxy, aralkoxy, --NHaralkyl, --NHalkyl, --NHalkylcycloalkyl or --NHaryl.These compounds are cardiovascular agents which exhibit thromboxane antagonist activity and thus are useful in the treatment of thrombotic and vasospastic disease.

Abstract: 7-Oxabicycloheptane imino interphenyleneoxy substituted prostaglandin analogs are provided having the structural formula ##STR1## wherein n is 1 or 2;R is H; lower alkyl, or alkali metal; andR.sup.1 is --OR.sup.2, ##STR2## where R.sup.2 is lower alkyl, aryl, aralkyl, alkanoyl or aroyl; andR.sup.3 is lower alkyl, aryl, aralkyl, alkoxy, aryloxy, aralkoxy, --NHaralkyl, --NHalkyl or --NHaryl. The compounds are useful in the treatment of thrombotic disease.

Abstract: Leukotriene biosynthesis in macrophage cells is inhibited by compounds having the formula ##STR1## and pharmaceutically acceptable salts thereof, wherein R.sub.1 and R.sub.2 are each hydrogen and R.sub.3 is alkyl or arylalkyl;R.sub.1 and R.sub.3 are each hydrogen and R.sub.2 is arylmethyl or arylcarbonyl;R.sub.1 is methyl, R.sub.2 is arylmethyl and R.sub.3 is hydrogen; orR.sub.1 is alkyl of seven or more carbons or arylalkyl and R.sub.2 and R.sub.3 are each hydrogen.

Abstract: p-Aminophenols are provided having the structure ##STR1## wherein m is 0 to 5; X is CH or N; R.sup.1 and R.sup.2 may be the same or different and are H, lower alkyl, aryl, hydroxy, hydroxyalkyleneoxy, alkylthio, alkoxy, alkanoyloxy, aryloxy, halo, carboxy, alkoxycarbonyl or amido; R.sup.3 is H, lower alkyl, alkanoyl or aroyl; and R.sup.4 is H, lower alkyl or alkanoyl, and including acid-addition salts thereof, with the proviso that when X is CH, m is 0 and R.sup.1 is H, and when R.sup.4 is H, R.sup.2 is other than alkoxy, H or hydroxy, and when R.sup.4 is benzoyl, R.sup.2 is other than H.These compounds together with the compounds defined in the above proviso are useful as inhibitors of leukotriene production and as such are useful as antiallergy, anti-inflammatory and anti-psoriatic agents.

Abstract: Cyclic aryl hydroxamic acids and derivatives thereof are provided having the structure ##STR1## wherein R is H or arylalkyl, and including acid-addition salts thereof. These compounds are useful as inhibitors of leukotriene production and as such are useful as antiallergy, anti-inflammatory and anti-psoriatic agents.

Abstract: Analogs of arachidonic acid are provided having the structure ##STR1## wherein R is CH.sub.2 OH or CO.sub.2 H and m is 1 or 2. These compounds are useful as inhibitors of leukotriene and prostaglandin biosynthesis and as such are useful an antiallergy and antiinflammatory agents.
