##STR1## The present invention relates to hitherto unknown compounds of formula, in which m and n stand for an integer from 0-5, p stands for 0 or 1, and q stands for an integer from 0-4, R.sub.1 and R.sub.2 are the same or different and stand for hydrogen, halogen, nitro, amino, alkyl or alkoxy; R.sub.3 is hydroxy, hydrogen, straight or branched, saturated or unsaturated C.sub.1 -C.sub.6 alkyl; R.sub.5 stands for an acidic group, e.g. carboxy, 1-H tetrazolyl, a sulphonic acid group, a sulfamyl group, a sulphinic acid group, or a hydroxamic acid group; R.sub.4 and R.sub.6 are the same or different and stand for hydrogen, straight or branched, saturated or unsaturated, unsubstituted or substituted C.sub.1 -C.sub.6 alkyl groups or unsubstituted or substituted aralkyl groups. R.sub.7 has the same meaning as R.sub.5 or represents a hydrogen, straight or branched, saturated or unsaturated, unsubstituted or substituted C.sub.1 -C.sub.6 -alkyl group. The present compounds are of value in the human and veterinary practice as lipoxygenase inhibitors and/or leukotriene antagonists.
本发明涉及一种以公式表示的迄今为止未知化合物,其中m和n代表0-5的整数,p代表0或1,q代表0-4的整数,R.sub.1和R.sub.2相同或不同,代表氢、卤素、硝基、氨基、烷基或烷氧基;R.sub.3代表羟基、氢、直链或支链、饱和或不饱和的C.sub.1-C.sub.6烷基;R.sub.5代表酸性基团,例如羧基、1-H四唑基、磺酸基团、磺酰胺基团、亚磺酸基团或羟肟酸基团;R.sub.4和R.sub.6相同或不同,代表氢、直链或支链、饱和或不饱和、未取代或取代的C.sub.1-C.sub.6烷基或未取代或取代的芳基烷基;R.sub.7具有与R.sub.5相同的含义,或代表氢、直链或支链、饱和或不饱和、未取代或取代的C.sub.1-C.sub.6烷基。这些化合物在人类和兽医实践中作为脂氧合酶抑制剂和/或白三烯受体拮抗剂具有价值。
