| abstract |
The present invention relates to hitherto unknown compounds of formula (I), in which formula (I) R1 stands for hydrogen, straight or branched, saturated or unsaturated, unsubstituted or substituted C1-C8-alkyl, aryl or for ar-C1-C4-alkyl, aryl or ar being unsubstituted or substituted phenyl, R2, R3, R4, R5, R6 and R7 are the same or different and stand for hydrogen, halogen, pseudo halogen, cyano, nitro, amino, carboxy, carbalkoxy, carbamyl, hydroxy, alkyl, alkoxy; n and m are the same or different and stand for an integer from 0-6; provided that n cannot be zero when A stands for carboxy and X and Q both stand for a bond; X stands for a bond or for O, S, S(O), S(O)2 or for NR8 where R8 is defined as R1 above; Q stands for a bond of for straight or branched, C1-C6-alkylene; A stands for an acidic group, e.g. for carboxy, 1H-tetrazolyl, a sulphonic acid group, a sulfamyl group, a sulphinic acid group or a hydroxamic acid group. The present compounds are of value in the human and veterinary practice as lipoxygenase inhibitors and/or leukotriene antagonists. |
