Novel aniline derivatives represented by the general formula (1):
[wherein, subject to certain provisos, R°, R1 and R2 are hydrogen, halogen, nitro, amino, carboxy, cyano, hydroxy, sulphonamido, lower alkyl, lower alkoxycarbonyl, lower alkoxy, lower alkanoyl, lower alkylamino, lower alkylthio, lower alkanoylamino or a group
(wherein R5 and R6 are hydrogen, lower alkyl or cycloalkyl or form a heterocyclic group with the adjacent nitrogen atom); R3 is cyano, nitro, halogen, lower alkyl or a lower alkoxy; m is an integer of 1 to 3; R4 is hydrogen or lower alkyl; and A is lower alkylene] and their salts act directly on the heart, and have myocardial contraction activity (positive inotropic activity) and coronary blood flow increasing activity, and are thus useful as cardiotonics.

[其中,除某些但书外,R°、R1 和 R2 是氢、卤素、硝基、
氨基、羧基、
氰基、羟基、磺酰胺基、低级烷基、低级烷氧羰基、低级烷氧基、低级烷酰基、低级烷
氨基、低级烷
硫基、低级烷酰
氨基或一个基团
(其中 R5 和 R6 为氢、低级烷基或环烷基,或与邻近的氮原子形成杂环基团);R3 为
氰基、硝基、卤素、低级烷基或低级烷氧基;m 为 1 至 3 的整数;R4 为氢或低级烷基;A 为低级亚烷基]及其盐类直接作用于心脏,具有心肌收缩活性(正性肌力活性)和增加冠状动脉血流量的活性,因此可用作强心剂。
