-

, (2008/06/13)

Phenol derivatives of the formula (I) wherein A and B have the same or different meanings and each represent one of the groups ?C=C?, cis?CH=CH? or trans?CH=CH?, R1 is hydrogen, an optionally substituted alkyl or phenyl group or a cycloalkyl group, R2 is hydrogen, methyl or ethyl, R3 represents hydrogen, acetyl or propionyl, R4 has the same meaning as R3 or represents an alkyl group, R5 is a carboxylic or a hydroxy group or a functional derivative of such groups or R5 is a nitrile group and R6 is hydrogen, an alkyl group or the group OR4 which specifically inhibit 5-lipoxygenase and are useful in pharmaceutical compositions for prophylaxis and treatment of diseases due to the action of leukotrienes. The compounds are prepared by reacting suitable acetylene compounds or metal derivatives thereof with alkyl or aryl halides or by means of Wittig reactions optionally followed by transforming the member R5 into another carboxylic acid derivative. By hydrogenation A and B may be varied within the scope of the definition.
