The present invention relates to compounds of the general formula ##STR1## wherein Ar represents a substituted or unsubstituted 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 alike 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. The compounds exhibit beta-adrenergic blocking activity and are also useful in the treatment of glaucoma.
本发明涉及一般式为##STR1##的化合物,其中Ar代表取代或未取代的杂环基团;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可能相同也可能不同,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成员的杂环基团,以及其药用盐。这些化合物表现出β-肾上腺素受体阻滞活性,并且在青光眼的治疗中也很有用。
