Compounds of general formula I are described, ##STR1## wherein X represents the group .dbd.CHR, .dbd.NR or an oxygen atom and A represents the groups --NR.sup.1 R.sup.2, wherein R.sup.1 and R.sup.2 represent alkyl, cycloalkyl or phenylalkyl groups, n represents the number 0, 1 or 2, R.sup.3 represents a hydrogen atom, a hydroxy or alkyl group or a group --(CH.sub.2).sub.n --N--R.sup.5 R.sup.6 (R.sup.5 and R.sup.6 being lower alkyl groups) and R.sup.4 is an alkyl or phenylalkyl group; two processes for preparing these compounds and the salts thereof are also described. The compounds have favourable effects on heart rate and can be used as vagal pacemakers for treating bradycardia and bradyarrhythmia in human and veterinary medicine. Some of these compounds also have very good antithrombotic effects.
通式I的化合物描述如下,其中X代表基团.dbd.CHR,.dbd.NR或氧原子,A代表基团--NR.sup.1 R.sup.2,其中R.sup.1和R.sup.2代表烷基、环烷基或苯基烷基基团,n代表数字0、1或2,R.sup.3代表氢原子、羟基或烷基基团或基团--(CH.sub.2).sub.n --N--R.sup.5 R.sup.6(R.sup.5和R.sup.6为较低的烷基基团),R.sup.4是烷基或苯基烷基基团;还描述了制备这些化合物及其盐的两种方法。这些化合物对心率有良好的影响,并可用作治疗人类和兽医学中的心动过缓和心动过缓性心律失常的迷走神经起搏器。其中一些化合物还具有非常好的抗血栓作用。
