Compounds of the formula
wherein the broken line represents an optional double bond; X is O, S, CH₂ or CH₂CH₂; R¹ is selected from the group consisting of hydrogen, halogen, C₁-C₆ alkoxy, C₁-C₆ alkanoyl, C₁-C₆ alkyl, and C₁-C₆ alkyl substituted with 1, 2 or 3 halogen atoms; R² is selected from the group consisting of phenyl, substituted phenyl, heterocyclic groups, and substituted heterocyclic groups, said substituted phenyl and substituted heterocyclic groups being substituted with 1 or 2 substituents independently selected from the group consisting of C₁-C₆ alkyl, trifluoromethyl, and halogen;
R³ and R⁴ are independently selected from the group consisting of hydrogen, halogen, C₁-C₆ alkyl, or trifluoromethyl, or R³ and R⁴, taken together with the carbon atoms to which they are attached, form a six-membered carbocyclic aromatic ring, said aromatic ring being optionally substituted with one or two substituents selected from the group consisting of halogen, C₁-C₆ alkyl, and C₁-C₆ alkyl substituted with 1, 2 or 3 halogen atoms; and the pharmaceutically acceptable salts thereof. The compounds are useful in treating inflammation or other prostaglandin or leukotriene mediated diseases.
