p-Aminophenols are provided having the structure ##STR1## wherein m is 0 to 5; X is CH or N; R.sup.1 and R.sup.2 may be the same or different and are H, lower alkyl, aryl, hydroxy, hydroxyalkyleneoxy, alkylthio, alkoxy, alkanoyloxy, aryloxy, halo, carboxy, alkoxycarbonyl or amido; R.sup.3 is H, lower alkyl, alkanoyl or aroyl; and R.sup.4 is H, lower alkyl or alkanoyl, and including acid-addition salts thereof, with the proviso that when X is CH, m is 0 and R.sup.1 is H, and when R.sup.4 is H, R.sup.2 is other than alkoxy, H or hydroxy, and when R.sup.4 is benzoyl, R.sup.2 is other than H. These compounds together with the compounds defined in the above proviso are useful as inhibitors of leukotriene production and as such are useful as antiallergy, anti-inflammatory and anti-psoriatic agents.
提供具有以下结构的对氨基酚类化合物:##STR1## 其中m为0至5;X为CH或N;R.sup.1和R.sup.2可以相同也可以不同,且为H、低烷基、芳基、羟基、羟基烷氧基、烷基硫醇、烷氧基、烷酰氧基、芳氧基、卤素、羧基、烷氧羰基或酰胺基;R.sup.3为H、低烷基、烷酰基或芳酰基;R.sup.4为H、低烷基或烷酰基,包括其酸加成盐。但当X为CH时,m为0且R.sup.1为H,且当R.sup.4为H时,R.sup.2不是烷氧基、H或羟基,当R.sup.4为苯甲酰基时,R.sup.2不是H。这些化合物以及上述限定的化合物对于抑制白三烯的产生非常有用,因此可用作抗过敏、抗炎和抗银屑病剂。
