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.
