Psoriasis in mammals is relieved by topically administering naphthalenes of the formula: ##STR1## wherein: R.sup.1 is lower alkoxy or optionally substituted phenoxy, R.sup.2 is the same as R.sup.1, or R.sup.2 is hydrogen, lower alkyl, optionally substituted phenyl or optionally substituted phenylalkyl, R.sup.3 is hydrogen, lower alkyl, lower alkoxy, halo, optionally substituted phenyl, optionally substituted phenyl-lower-alkyl or optionally substituted phenyl-lower-alkoxy, and m is 1 or 2; both X groups are the same and X is either --C(O)OR.sup.4 or --C(O)NR.sup.5 R.sup.6, wherein R.sup.4 is alkyl, phenyl or benzyl optionally substituted with one or two lower alkyl groups, lower alkoxy groups or halo; and R.sup.5 and R.sup.6 are independently hydrogen, lower alkyl, cycloalkyl or phenyl optionally substituted with one or two lower alkyl groups, lower alkoxy groups or halo. The compounds of this invention are also useful for the treatment of disease-states caused by lipoxygenase activity in mammals, particularly 5-lipoxygenase activity, when administered systemically.
在哺乳动物中,通过局部给予以下式的萘醚类化合物可缓解牛皮癣:##STR1## 其中:R.sup.1为较低的烷氧基或可选择取代的苯氧基,R.sup.2与R.sup.1相同,或者R.sup.2为氢、较低烷基、可选择取代的苯基或可选择取代的苯基烷基,R.sup.3为氢、较低烷基、较低烷氧基、卤素、可选择取代的苯基、可选择取代的苯基烷基或可选择取代的苯基烷氧基,m为1或2;两个X基团相同,X为--C(O)OR.sup.4或--C(O)NR.sup.5 R.sup.6,其中R.sup.4为烷基、苯基或苄基,可选择取代为一个或两个较低烷基基团、较低烷氧基团或卤素;而R.sup.5和R.sup.6独立地为氢、较低烷基、环烷基或可选择取代的苯基,其可选择取代为一个或两个较低烷基基团、较低烷氧基团或卤素。本发明的这些化合物在系统给药时也可用于治疗由脂氧合酶活性引起的哺乳动物疾病状态,特别是5-脂氧合酶活性。
