Compositions of matter are disclosed of compounds of the formula ##STR1## and the pharmaceutically acceptable acid addition salts thereof wherein X represents a halo, lower alkyl, hydrogen, trifluoromethyl, phenyl, or lower alkoxy substituent; Y represents --CN, --CONH.sub.2, --CON(R.sub.1).sub.2 or --CO.sub.2 R.sub.1 where R.sub.1 is a lower alkyl; m is the integer 1 or 2 and n is an integer from 1 to 3 inclusive; R.sub.2 represents lower alkyl; R.sub.3 represents lower alkyl or acetyl, aroyl, phenacetyl or trifluoroacetyl; A, B, and D are carbonyl or methylene such that when one of A, B, or D is carbonyl, the others are methylene and R.sub.3 is lower alkyl, whereas when R.sub.3 is acetyl, aroyl, phenacetyl or trifluoroacetyl, A, B, and D are methylene. These compounds have utility as antiarrhythmic agents.
本发明揭示了化合物的组合物,其具有以下公式:##STR1##以及其药学上可接受的酸加合物盐,其中X表示卤素,低烷基,氢,三氟甲基,苯基或低烷氧基取代基; Y表示--CN,--CONH.sub.2,--CON(R.sub.1).sub.2或--CO.sub.2R.sub.1,其中R.sub.1是低烷基; m是整数1或2,n是整数1至3(含); R.sub.2表示低烷基; R.sub.3表示低烷基或乙酰基,酰基,苯乙酰基或三氟乙酰基; A,B和D是羰基或亚甲基,使得当A、B或D中的一个是羰基时,其他的是亚甲基,而R.sub.3是低烷基,而当R.sub.3是乙酰基,酰基,苯乙酰基或三氟乙酰基时,A,B和D是亚甲基。这些化合物具有抗心律失常药物的实用性。
