A dibenz[b,e]oxepin derivative represented by the formula (I):
wherein A1 is a hydrogen atom, a methyl group, (CH2)mOR1 [where m is an integer of 1 to 4, and R1 is a hydrogen atom, CH2CH(OH)CH2OCH2CH3, CH2CH(OAc)CH2OCH2CH3 or CH2OCH2CH2OCH3], CH(CH3)CH2OR1 (where R1 has the same meaning as defined above), CH = CHC02R2 (where R2 is a hydrogen atom or a lower alkyl group), (CH2)nCO2R2 (where n is an integer of 1 to 3, and R has the same meaning as defined above), CH(CH3)CO2R2 (where R2 has the same meaning as defined above), CO2(CH2)NR3R4 (where is an integer of 1 to 6, and R3 and R4 are the same or different lower alkyl groups), CONHR5 (where R5 is a lower alkyl group). CO2CH2CH(OR6),CH2OCH2CH3 (where R6 is a hydrogen atom or an acetyl group), C02CH2CH20CH2CH20H or CO2X1 (where X1 is a hydrogen atom or a lower alkyl group). A2 is a 4-lower alkylpiperazino group, a 4-lower alkylhomopiperazino group or Y-(CH2)pNR7R8 (where Y is NH, O or S, p is an integer of 2 to 5, and R7 and R8 are the same or different hydrogen atoms or lower alkyl groups). One of A3 and A4 is COR [where R9 is a hydroxyl group, a lower alkoxy group, an 1-(ethoxycarbony- loxy)ethoxy group or an amino group] or a cyano group, and the other is a hydrogen atom; or A3 is a hydrogen atom or an alkyl group having 1 to 3 carbon atoms and is a substituent at the 4-position, and A4 is a hydrogen atom.} has antiallergic activity such as antiasthmatic activity.
