Novel compounds have the formula:
or are pharmaceutically acceptable salts thereof. In the formula,
Y is -(CR²=CR²)n-or -(C≡C)n-;
R¹ is H, halogen, C₁-C₈ alkyl, C₂-C₈ alkenyl, C₂-C₈ alkynyl, -CF₃, OR², -SR², -SOR², -SO₂R², -NR²R², -CHO, -COOR², -(C=O)R², -C(OH)R²R², -CN, -NO₂, substituted or unsubstituted phenyl, substituted or unsubstituted benzyl, or substituted or unsubstituted phenethyl;
R² is H, C₁ -C₈ alkyl, C₂-C₈ alkenyl, C₂-C₈ alkynyl, -CF₃, substituted or unsubstituted phenyl, substituted or unsubstituted benzyl, or substituted or unsubstituted phenethyl;
R³ is -(A)m-(CR²R²)m-(CR²R⁴)m-CR²R, with the proviso that R³ is not CHO when it is para to Y;
R⁴ is H, halogen, -NO₂, -OR², -SR², NR²R², or C₁-C₈ alkyl, or (R⁴)₂ is O=;
A is =C=O or CR²(OR⁶); R⁶ is H, C₁-C₆ alkyl, -(C=O)R⁷, unsubstituted phenyl or unsubstituted benzyl;
R⁷ is H, C₁-C₈ alkyl, C₂-C₈ alkenyl, C₂-C₈ alkynyl, -CF₃, or unsubstituted phenyl, benzyl, or phenethyl;
each m is 0 or integer of from 1 to 8, provided that at least one m is not 0;
and n is 1 or 2. The compounds are antagonists of leukotrienes and inhibitors of leukotriene biosynthesis. These compounds are useful as anti-asthmatic, anti-allergic, anti-inflammatory and cytoprotective agents.
