Compounds of the formula:
    wherein
   R¹ is hydrogen, alkyl, cycloalkyl, carboxyl or alkoxy carbonyl;
   R² is hydrogen, halogen or alkyl;
   A is a group of the formula
    Z and W are independently hydrogen or alkyl or Z and W taken together are alkylene;
   n is an integer of from 0-1;
   m is an integer of from 0-3;
   X is -CH₂OH or -R⁴COR⁵;
   Y is halogen, alkoxy, acyloxy, hydroxy, alkyl, nitro, trifluoromethyl, hydrogen or cyano;
   R³ is hydrogen, alkyl or cycloalkyl;
   R⁴ is a direct bond or CH₂;
   R⁵ is hydroxy, alkoxy, NHR⁶ or
    R⁶ is hydrogen or alkyl; and
   R⁷ and R⁸ are, independently, hydrogen or alkyl or R⁷ and R⁸ , taken together, are alkylene provided that when m is 0 and n is 0, one of R¹ or R³ is cycloalkyl,
and enantiomers, diastereomers, racemates and salts with pharmaceutically acceptable bases, antagonize LTD₄ action and, thus, are useful in treating bronchial asthma, pulmonary anaphylaxis, cystic fibrosis, chronic bronchitis, bronchiectasis, respiratory distress syndrome and pulmonary oedema.
                            式中的化合物:
 其中
