Compounds of general formula ##STR1## wherein one of the groups R.sub.1 and R.sub.3 is a straight-chain or branched oxoalkyl group consisting from 5 to 8 carbon atoms and the oxygen atom is attached to a non-terminal carbon atom and is separated from the nearest ring nitrogen atom by at least 3 carbon atoms in (.omega.-1)-oxoalkyl groups and by at least 4 carbon atoms in oxoalkyl groups in which the oxygen atom is separated from the terminal carbon atom by more than one carbon atom, R.sub.2 and the other one of groups R.sub.1 and R.sub.3 are straight chain or branched alkyl groups containing from 1 to 12 carbon atoms but wherein that group R.sub.1 or R.sub.3 which is other than an oxoalkyl group may also be hydrogen, one nitrogen-bound substituent being hydrogen or alkyl containing more than 1 carbon atom, and physiologically acceptable acid addition salts thereof, a process for their preparation and pharmaceutical compositions containing said compounds.
通式为##STR1##的化合物,其中R.sub.1和R.sub.3中的一个是由5到8个碳原子组成的直链或支链氧烷基基团,氧原子连接到非末端碳原子,并且在(.omega.-1)-氧烷基基团中,氧原子与最近的环氮原子至少相隔3个碳原子,在氧烷基基团中,氧原子与末端碳原子相隔超过一个碳原子时,至少相隔4个碳原子;R.sub.2和R.sub.1和R.sub.3中的另一个是由1到12个碳原子组成的直链或支链烷基基团,但R.sub.1或R.sub.3中除了氧烷基基团外,也可以是氢,一个与氮相结合的取代基是氢或含有多于1个碳原子的烷基,以及其生理上可接受的酸盐,其制备方法和含有该化合物的药物组合物。
