A compound represented by the formula:
[wherein ring A represents a homocycle optionally having substituents or a nitrogen-containing heterocycle optionally having substituents; D and E are O or S; one of R1 and R2 represents a group represented by the formula:
(wherein Ar1 and Ar2 represent an aromatic group optionally having substituents; Ar1 and Ar2 may form a condensed cyclic group optionally having substituents together with an adjacent carbon atom; ring B represents a nitrogen-containing heterocycle optionally having substituents; X and Y are a bond, O, S(O)p (p is an integer of 0 to 2), NR4 (R4 is H or a lower alkyl group) or a bivalent straight-chained lower hydrocarbon group, which may contain 1 to 3 hetero atoms, optionally having substituents; and R3 represents H, a hydroxy group optionally having substituents or an optionally esterified carboxyl group); and the other is a hydrogen atom, a cyano group or a hydrocarbon group optionally having substituents], or a salt thereof, has an anti-histaminic action, an anti-inflammatory action, eosinophil chemotaxis-inhibiting action, and is useful for preventing or treating asthma, allergic conjunctivitis, allergic rhinitis, urticaria, atopic dermatitis and so on.
一种由以下式表示的化合物:[其中环A代表一个可选具有取代基的同环或一个可选具有取代基的含氮杂环;D和E为O或S;R1和R2中的一个代表一个由以下式表示的基团:(其中Ar1和Ar2代表一个可选具有取代基的芳香族基团;Ar1和Ar2可以与相邻的碳原子一起形成一个可选具有取代基的紧邻环基团;环B代表一个可选具有取代基的含氮杂环;X和Y为键合,O,S(O)p (p为0到2的整数),NR4 (R4为H或较低烷基基团)或一个双价的直链较低碳氢基团,其中可能含有1到3个杂原子,可选具有取代基;R3代表H,一个可选具有取代基的羟基或一个可选酯化的羧基);另一个是氢原子、氰基或可选具有取代基的碳氢基团],或其盐,具有抗组胺作用、抗炎作用、嗜酸性粒细胞趋化抑制作用,可用于预防或治疗哮喘、过敏性结膜炎、过敏性鼻炎、荨麻疹、特应性皮炎等。
