Disclosed is a sulfonamide derivative represented by following formula (I) and a medicine for the treatment of asthma comprising the sulfonamide derivative as an active ingredient which exhibits bronchodilation effect. ##STR1## wherein X represents a quinoline residue represented by formula (II) or an isoquinoline residue represented by formula (III) ##STR2## where R.sup.1 is a hydrogen atom, a halogen atom, a lower alkyl group or a lower alkoxy group, or ##STR3## where R.sup.2 is a hydrogen atom or a hydroxyl group, and wherein: when X is quinoline residue (II), n is zero or 1, in which, when n is zero, R.sup.4 is an unsubstituted or substituted diazacycloalkyl group, and when n is 1, R.sup.3 is a hydrogen atom or a lower alkyl group and R.sup.4 is an unsubstituted or substituted aralkylamino group or an unsubstituted or substituted diazacycloalkyl group; and when X is isoquinoline residue (III), n is 1, in which, R.sup.3 is a hydrogen atom or a lower alkyl group and R.sup.4 is a 3,4-methylenedioxyphenethylamino group, a 3,4-methylenedioxybenzylamino group or an unsubstituted or substituted diazacycloalkyl group, with the proviso that when R.sup.4 is an unsubstituted or substituted diazacycloalkyl group, the diazacycloalkyl group is bonded at a nitrogen atom thereof.
本发明涉及一种磺酰胺衍生物,其表示为以下式(I),以及一种治疗哮喘的药物,其中该磺酰胺衍生物作为活性成分表现出支气管扩张作用。其中,X代表由式(II)表示的喹啉残基或由式(III)表示的异喹啉残基,其中R1是氢原子、卤素原子、低级烷基或低级烷氧基,或其中之一:其中R2是氢原子或羟基;当X为喹啉残基(II)时,n为零或1,在其中,当n为零时,R4是未取代或取代的二氮环烷基,当n为1时,R3是氢原子或低级烷基,R4是未取代或取代的芳基烷氨基或未取代或取代的二氮环烷基;当X为异喹啉残基(III)时,n为1,在其中,R3是氢原子或低级烷基,R4是3,4-亚甲二氧基苯乙胺基、3,4-亚甲二氧基苄胺基或未取代或取代的二氮环烷基,但当R4是未取代或取代的二氮环烷基时,该二氮环烷基与其中的氮原子相连。
