Novel compounds of the general formula ##STR1## wherein Ar represents a substituted or unsubstituted aromatic or heterocyclic group; W represents alkylene of from 1 to about 10 carbon atoms; and B represents --NR.sub.2 COR.sub.1, --NR.sub.2 CONR.sub.1 R.sub.3, --NR.sub.2 SO.sub.2 R.sub.1, --NR.sub.2 SO.sub.2 NR.sub.1 R.sub.3, or --NR.sub.2 COOR.sub.1 wherein R.sub.1, R.sub.2 and R.sub.3 may be the same or different and may be hydrogen, alkyl, alkoxyalkyl, cycloalkyl, alkenyl, alkynyl, aryl, heteroaryl, or aralkyl, except that R.sub.1 is not hydrogen when B is --NR.sub.2 SO.sub.2 R.sub.1 or --NR.sub.2 COOR.sub.1, or R.sub.1 and R.sub.3 may together with N form a 5 to 7 membered heterocyclic group; and the pharmaceutically acceptable salts thereof. These compounds exhibit .beta.-adrenergic blocking activity and are also useful in the treatment of glaucoma.
一般式为##STR1##的新化合物,其中Ar代表取代或未取代的芳香或杂环基;W代表1至约10个碳原子的烷基;B代表--NR.sub.2 COR.sub.1、--NR.sub.2 CONR.sub.1 R.sub.3、--NR.sub.2 SO.sub.2 R.sub.1、--NR.sub.2 SO.sub.2 NR.sub.1 R.sub.3或--NR.sub.2 COOR.sub.1,其中R.sub.1、R.sub.2和R.sub.3可以相同或不同,可以是氢、烷基、烷氧基烷基、环烷基、烯基、炔基、芳基、杂芳基或芳基烷基,但当B为--NR.sub.2 SO.sub.2 R.sub.1或--NR.sub.2 COOR.sub.1时,R.sub.1不是氢,或者R.sub.1和R.sub.3可以与N一起形成5到7个成员的杂环基;以及其药学上可接受的盐。这些化合物表现出β-
