1,4-Dihydro-2H-isoquinoline derivatives of the general formula I ##SPC1## in which R.sup.1 represents hydrogen or straight chain or branched alkyl of 1 to 6 carbon atoms, R.sup.2 represents low molecular dialkylaminoalkyl, in which both alkyl groups of the dialkylamino group together with the nitrogen atom may also form a 5-, 6- or 7-membered saturated ring in which one carbon atom may be substituted by an oxygen atom, a sulfur atom or another nitrogen atom which may be substituted by hydrogen, C.sub.1 -C.sub.4 -alkyl or phenyl, or R.sup.1 and R.sup.2 together may form a 5- or 6-membered saturated ring containing 1 nitrogen atom, R.sup.3 represents phenyl which may be mono- or di-substituted by halogen, nitro, amino or sulfamoyl, or acylamino or alkyl each containing 1 to 4 carbon atoms, or pyridyl R.sup.4 and R.sup.5, which may identical or different, represent hydrogen or alkoxy of 1 to 4 carbon atoms, and X represent oxygen or sulfur, Their physiologically tolerated salts, process for preparing them. The compounds are active on the coronary circulation and are distinguished in particular by an anti-arrhythmic action and may, therefore, be used in the treatment of disorders of the heart rhythm.
1,4-二氢-2H-异喹啉衍生物的一般式I ##SPC1##,其中R.sup.1代表氢或1至6个碳原子的直链或支链烷基,R.sup.2代表低分子二烷基氨基烷基,其中二烷基氨基基的两个烷基基团与氮原子一起也可以形成一个含有5、6或7个饱和环的环,其中一个碳原子可以被氧原子、硫原子或另一个氮原子取代,该氮原子可以被氢、C.sub.1 -C.sub.4 -烷基或苯基取代,或者R.sup.1和R.sup.2一起可以形成含有1个氮原子的5或6个饱和环,R.sup.3代表苯基,可以被卤素、硝基、氨基或磺酰基单取代或双取代,或者含有1至4个碳原子的酰胺基或烷基,或吡啶基R.sup.4和R.sup.5,可以相同或不同,代表1至4个碳原子的氢或烷氧基,X代表氧或硫,它们的生理耐受盐,制备它们的方法。这些化合物对冠状循环具有活性,并且特别具有抗心律失常作用,因此可以用于治疗心律失常的疾病。
