Compounds of the general formula: ##STR1## and non-toxic physiologically acceptable salts thereof, in which R.sub.1 is a halogen atom or a group NR.sub.2 R.sub.3 ; R.sub.2 and R.sub.3, which may be the same or different, are hydrogen or (C.sub.1 -C.sub.6) straight or branched chain alkyl or R.sub.2 and R.sub.3 may, together with the nitrogen atom, form a 5 or 6 membered heterocyclic ring which may contain a further hetero atom selected from O, N or S; or R.sub.2 may be hydrogen and R.sub.3 may by group R.sub.4 CO or R.sub.4 SO.sub.2 where R.sub.4 is hydrogen or alkyl (C.sub.1-4); R.sub.5 is hydrogen or one or more halogen atoms or hydroxy or alkoxy (C.sub.1-4) groups; and X is CH.sub.2, O or a group NR.sub.6 where R.sub.6 is hydrogen or alkyl (C.sub.1-4). These compounds block .beta.-adrenoreceptors.
一般式为:##STR1##及其非毒性生理可接受的盐,其中R.sub.1是卤原子或基NR.sub.2R.sub.3; R.sub.2和R.sub.3可以相同也可以不同,是氢或(C.sub.1-C.sub.6)直链或支链烷基,或者R.sub.2和R.sub.3可以与氮原子一起形成一个5或6元杂环环,该环可以含有进一步从O,N或S中选择的杂原子;或者R.sub.2可以是氢,R.sub.3可以是基R.sub.4CO或R.sub.4SO.sub.2,其中R.sub.4是氢或烷基(C.sub.1-4);R.sub.5是氢或一个或多个卤原子或羟基或烷氧基(C.sub.1-4)基团;X是CH.sub.2,O或基NR.sub.6,其中R.sub.6是氢或烷基(C.sub.1-4)。这些化合物阻断β-肾上腺素能受体。
