ABSTRACT:
The present invention relates to compounds of the formula Iin which one of the radicals R8 and R9 is a hydrogen atom or an alkyl group and the other is hydroxyl, alkoxy or acyloxy or where R8 and R9, together with the carbon atom to which they are bonded, are a carbonyl group and the radicals R1 to R7 have the meanings indicated in the description.The compounds inhibit the release of various mediators of the arachidonic acid cascade and can thus be used for the prevention of allergically induced disorders or for the treatment of disorders of the rheumatic type.
