Abstract
Compounds of the structure ##STR1## where A is straight or branched divalent alkylene or divalent cycloalkylene, R.sub.1 is selected from hydrogen; alkylthio; optionally substituted phenylthio; optionally substituted phenylalkylthio; optionally substituted 2-, 3-, and 4-pyridyl; optionally substituted 2-, and 3-thienylthio; and optionally substituted 2-thiazolythio, R.sub.2 is selected from --COOB; --COOalkyl; --COOalkyl(carbocyclic aryl); --CONR.sub.5 R.sub.6 ; --COR.sub.6 ; and --OH, R.sub.3 is selected from phenylalkyl and heteroarylalkyl, and R.sub.4 is selected from optionally substituted alkoxy(carbocyclic aryl); optionally substituted carbocyclic aryloxy; optionally substituted heteroarylalkoxy; and optionally substituted heteroaryloxy are potent inhibitors of lipoxygenase enzymes and thus inhibit the biosynthesis of of leukotrienes. These compounds are useful in the treatment or amelioration of allergic and inflammatory disease states.
