An agent for preventing/treating respiratory diseases contains, as an active ingredient, a compound represented by following Formula (I):
wherein A is a group represented by L-W [wherein L is a bond or CH2; and W is O, SOn (wherein n is 0 to 2), or —NR7— (wherein R7 is hydrogen or lower alkyl)]; each of G1 and G2 is (CH2)r (wherein r is 0 to 2), provided that when n is 1, G1 and G2 may be bridged by lower alkylene; Y is a lower alkylene or (substituted) benzylidene; Z is a bond or O, provided that when Z is a bond, Y may form a 5- or 6-membered ring with carbon on the benzene ring; R1 is, for example, NO2, a lower alkoxycarbonyl, (substituted) carbamoyl, (protected) hydroxyl group, (protected) carboxyl, or (protected) N-hydroxycarbamoyl; each of R2 and R3 is hydrogen, halogen, (halogenated) lower alkyl, (halogenated) lower alkoxy or NO2; each of R4 and R5 is, for example, hydrogen, halogen, (halogenated) lower alkyl, (halogenated) lower alkoxy, CN, or lower alkylsulfonyl; and R6 is hydrogen or lower alkyl, a salt thereof or a solvate of them. It has excellent antitussive activity when used as an agent for preventing/treating respiratory diseases such as lung cancer, common cold syndrome, pulmonary tuberculosis, pneumonia, acute bronchitis or chronic bronchitis.
预防/治疗呼吸系统疾病的药剂包含以下式(I)所表示的化合物作为活性成分:其中A是由L-W表示的基团[其中L是键或CH2; W是O,SO n(其中n为0至2),或-NR7-(其中R7是氢或低级烷基)];G1和G2分别为(CH2)r(其中r为0至2),但当n为1时,G1和G2可以由低级烷基桥接;Y是低级烷基或(取代)苯甲亚基;Z是键或O,但当Z是键时,Y可以与苯环上的碳形成5-或6-成员环;R1是例如NO2,低级烷氧羰基,(取代)氨基甲酰基,(保护)羟基,(保护)羧基或(保护)N-羟基氨基甲酰基;R2和R3分别是氢,卤素,(卤代)低级烷基,(卤代)低级烷氧基或NO2;R4和R5分别是例如氢,卤素,(卤代)低级烷基,(卤代)低级烷氧基,CN或低级烷基磺酰基;R6是氢或低级烷基,其盐或溶剂化物。当用作预防/治疗肺癌,普通感冒综合症,肺结核,肺炎,急性支气管炎或慢性支气管炎等呼吸系统疾病的药剂时,具有出色的止咳活性。
