This invention encompasses compounds of Formula 1 and the pharmaceutically acceptable salts thereof. wherein R1 represents alkyl having 2-6 carbon atoms; R2 represents methyl or ethyl; R3 represents alkyl having 1 to 5 carbon atoms; W represents (CH?)x where x is 2 to 7, alkylene having 2 to 7 carbon atoms, alkenylene having 3 to 7 carbon atoms, alkynylene having 3 to 7 carbon atoms, or cyclopentyl; R? represents hydrogen, alkyl having 2-5 carbon atoms, alkenyl having 2 to 5 carbon atoms, or alkynyl having 2 to 5 carbon atoms; Q represents oxygen or CH?; B represents CH?, C=O or CH-OH; R? represents hydrogen, alkyl having 1 to 6 carbon atoms, or R? and R? together optionally represent a carbon to carbon bond; or R? represents alkanoyl having 2 to 4 carbon atoms, carboxy, alkoxycarbonyl, or (CH?)y-CO?R? wherein y is 0 to 4 and R? is hydrogen or alkyl having 1 to 6 carbon atoms; and A represents-Z-CO?R? or-Z-COR?R1? wherein R? represents hydrogen or alkyl having 1 to 6 carbon atoms, R?, R1?, represent hydrogen, alkyl having 1 to 6 carbon atoms, or cycloalkyl having 3 to 6 carbon atoms or NR?R1? form a heterocyclic ring, and wherein Z is absent or represents straight or branched chain alkylene or alkenylene having up to 6 carbon atoms.These compounds are selective antagonists of leukotriene B?(LTB?) with little or no antagonism of leukotriene D? (LTD?) and are useful anti-inflammatory agents for treating inflammatory bowel disease, rheumatoid arthritis, gout and psoriasis.
