The present invention provides a compound, an oxepin derivative having excellent histamine receptor antagonistic action, which is useful as an antihistamine. The oxepin derivative of the present invention has a potent histamine receptor antagonistic action. Further, the compound of the present invention shows low intracerebral migration even when a mouse that is orally administered with the compound is subjected to an intracerebral receptor binding test, so that the compound has preferred properties of alleviating side effects in the central nervous system, such as drowsiness. The oxepin derivative of the present invention is very useful as a novel antihistamine having smaller side effects in the central nervous system, such as drowsiness.
本发明提供了一种化合物,即一种具有出色的组胺受体拮抗作用的噁吖啶衍生物,可用作抗组胺药。本发明的噁吖啶衍生物具有强效的组胺受体拮抗作用。此外,本发明的化合物即使经口给小鼠并进行颅内受体结合试验时,也表现出低颅内迁移,因此该化合物具有减轻中枢神经系统副作用(如嗜睡)的优良特性。本发明的噁吖啶衍生物非常有用,可作为一种新型抗组胺药,其中枢神经系统的副作用(如嗜睡)更小。
