Isoquinolines are disclosed of the formula (I) ##STR1## wherein R independently represents hydrogen, hydroxyl or alkoxy having 1 to 4 carbon atoms, R.sup.1 is hydrogen, alkyl having 1 to 4 carbon atoms and optionally substituted with phenyl, phenyl optionally substituted with one or more halogen or alkoxy group, cyano or carbomoyl, R.sup.2 is phenyl optionally substituted with one or more halogen, alkoxy or carboxyl, or a group of the general formula A ##STR2## wherein R.sup.3 is hydrogen, a straight or branched chained alkyl having 1 to 4 carbon atoms or phenyl, m and n independently represent 0, 1 or 2, with the proviso that m+n is at least 1, R.sup.4 is hydrogen, phenyl, hydroxyl, acyloxy, carboxyl, alkoxycarbonyl having 1 to 6 carbon atoms, carbamoyl, carbazoyl or dialkylamino containing 1 to 6 carbon atoms in the alkyl moiety, or R.sup.2 is a straight or branched chained alkylene group having 1 to 6 carbon atoms, and the dotted line stands for a further carbon-carbon bond or hydrogen atoms in the 3- and 4-positions of the ring, or salts thereof. The new compounds are potent diuretic agents.
Isoquinolines的化学结构式(I)如下:其中R独立地代表氢、羟基或含有1至4个碳原子的烷氧基,R.sup.1代表氢、含有1至4个碳原子的烷基,可选择地取代苯基,苯基可选择地取代一个或多个卤素或烷氧基,氰基或羰基,R.sup.2是苯基,可选择地取代一个或多个卤素、烷氧基或羧基,或者是一般式A的基团,其中R.sup.3是氢、直链或支链烷基(含有1至4个碳原子)或苯基,m和n独立地表示0、1或2,但m+n至少为1,R.sup.4是氢、苯基、羟基、乙酰氧基、羧基、含有1至6个碳原子的烷氧羰基、氨基甲酰、咖巴唑基或二烷基胺基(烷基中含有1至6个碳原子),或者R.sup.2是直链或支链烷基(含有1至6个碳原子),虚线代表环的3-和4-位上的进一步碳-碳键或氢原子,或其盐。这些新化合物是有效的利尿剂。
