发明名称 Benzopyrrolidinone compounds as bronchospastic agents
摘要 New benzopyrrolidinone compounds, which can be used as medicaments and correspond to the formula <IMAGE> in which: either: R1 and R2 together represent, with the bond of the etherocycle to which they are attached, an optionally substituted benzene nucleus and, simultaneously, R3 and R4 are hydrogen, (C1-C4)alkyl or (C5-C6)cycloalkyl; or: R1 is hydrogen, R4 is a single bond and R2 and R3 together represent, with the bond of the heterocycle to which they are bonded, an optionally substituted benzene nucleus; and A is a straight or branched hydrocarbon chain having from 2 to 6 carbon atoms that is optionally substituted by hydroxy; X is a single bond, oxygen or sulphur; and Y is hydrogen, halogen or (C1-C5)alkyl or alkoxy. These new compounds and the physiologically tolerable salts thereof can be used therapeutically, especially in the treatment of bronchospastic disorders and inflammations in the ENT area.
