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 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; X and Y are different and are either R.sup.4 or --C(O)W wherein R.sup.4 is lower alkyl or optionally substituted phenyl-lower-alkyl; W is --OR.sup.5 or --NR.sup.6 R.sup.7, wherein R.sup.5 is alkyl, optionally substituted phenyl or optionally substituted benzyl; and R.sup.6 and R.sup.7 are independently hydrogen, lower alkyl, cycloalkyl or optionally substituted phenyl. 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烯类化合物可缓解牛皮癣:##STR1## 其中:R.sup.1是较低的烷氧基或可选择地取代的苯氧基;R.sup.2是氢、较低的烷基、可选择地取代的苯基或可选择地取代的苯基烷基;R.sup.3是氢、较低的烷基、较低的烷氧基、卤素、可选择地取代的苯基、可选择地取代的苯基烷基或可选择地取代的苯基烷氧基,m为1或2;X和Y不同,可以是R.sup.4或--C(O)W,其中R.sup.4是较低的烷基或可选择地取代的苯基烷基;W是--OR.sup.5或--NR.sup.6 R.sup.7,其中R.sup.5是烷基、可选择地取代的苯基或可选择地取代的苄基;而R.sup.6和R.sup.7独立地是氢、较低的烷基、环烷基或可选择地取代的苯基。本发明的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。
