Aminophenol derivatives of the following formula (I)
wherein X is hydrogen atom, lower alkyl or a protecting group for phenolic hydroxy, Y is hydrogen atom or lower alkyl, Z is hydrogen atom, lower alkyl, halogen atom or trifluoromethyl, A is hydrogen atom or lower alkyl, t is an integer of 1 to 5, l and m are respectively an integer of 2 to 4, E and W are nitrogen atoms, F is a direct bond or oxygen atom, P and Q are each hydrogen atom, halogen atom, lower alkyl or lower alkoxy, and R⁸ is hydrogen atom, hydroxy or a hydroxy-protecting group, and their pharmcologically acceptable salts. Since the aminophenol derivatives (I) of the present invention have excellent antioxidative action and antiinflammatory and antiallergic action in mammalian animals including human, they are extremely useful as pharmaceuticals such as an antiinflammatory or an antiallergic.
下式(I)的氨基苯酚衍生物
其中 X 为氢原子、低级烷基或酚羟基保护基,Y 为氢原子或低级烷基,Z 为氢原子、低级烷基、卤素原子或三氟甲基,A 为氢原子或低级烷基,t 为 1 至 5 的整数,l 和 m 分别为 2 至 4 的整数、E和W是氮原子,F是直接键或氧原子,P和Q分别是氢原子、卤素原子、低级烷基或低级烷氧基,R⁸是氢原子、羟基或羟基保护基团,以及它们的药学上可接受的盐。由于本发明的氨基苯酚衍生物(I)在哺乳动物(包括人类)中具有优异的抗氧化作用、抗炎作用和抗过敏作用,因此它们作为抗炎或抗过敏等药物非常有用。
