    Abstract: The present invention provides compounds having the structure Y-Het-[Q1]-X-[Q2]-Z which inhibit the catalytic action of lipoxygenase enzymes, particularly 5-lipoxygenase, and thereby reduce the biosynthesis of leukotrienes B4, C4, D4, and E4. In the generic formula given above, X is oxygen or sulfur and Het is a heteroaryl group selected from the group consisting of furyl, thienyl, 2-, 3-, and 4-pyridyl, 2- and 3-benzo[b]furyl, 2- and 3-benzo[b]thienyl and thienothienyl. Y is one or two substituents independently selected from hydrogen, hydroxy, halogen, cyano, alkyl, haloalkyl, alkoxy, alkylthio, alkoxyaryl, alkylthioaryl, arylalkoxy, arylalkylthio, aryloxy, arylthio, alkylamido, cycloalkyl, alkanoyl, alkoxycarbonyl, amino, alkylamino, dialkylamino, and the following groups wherein R, at each occurrence, is independently selected from hydrogen and alkyl of from one to six carbon atoms: -CRROR, -NRC(O)R, -NRC(O)OR, and -C(O)NRR. The group Q1 is absent or is divalent alkylene of from one to six carbon atoms, and Q2 is divalent alkylene from two to ten carbon atoms. The group Z is N(OR1)COR2 where R1 is selected from hydrogen or a pharmaceutically suitable salt. R2 is selected from hydrogen; alkyl; cycloalkyl; amino; alkylamino, optionally substituted by hydroxyl, halogen, alkoxy or carboxyl; dialkylamino in which the alkyl groups are independently optionally substituted by hydroxyl, halogen, alkoxy or carboxyl; cycloalkylamino; 2-hydroxyethylamino; N-morpholino; N-thiomorpholino; N-piperazino; N'-alkyl-N-piperazino and cyclopropylmethylamino.
