Compounds of the general formula ##STR1## and physiologically acceptable salts, hydrates and bioprecursors thereof are disclosed, in which R.sub.1 and R.sub.2, which may be the same or different, represent hydrogen, lower alkyl, cycloalkyl, aralkyl or lower alkenyl groups, which alkyl groups may be interrupted by an oxygen atom or a group ##STR2## in which R.sub.4 represents hydrogen or lower alkyl; or R.sub.1 and R.sub.2 may, together with the nitrogen atom to which they are attached form a heterocyclic ring which may contain other hetero functions selected from --O-- and ##STR3## R.sub.3 represents hydrogen, lower alkyl, lower alkenyl or alkoxyalkyl; X represents --O--, --S-- or --CH.sub.2 --; Y represents .dbd.S, .dbd.O, .dbd.NR.sub.5 or .dbd.CHR.sub.6 ; in which R.sub.5 is hydrogen, nitro, cyano, lower alkyl, aryl, alkylsulphonyl or arylsulphonyl and R.sub.6 represents nitro, alkylsulphonyl or arylsulphonyl; m is an integer from 2 to 4 inclusive; n is 1 or 2 or, when X is S or CH.sub.2, n is zero, 1 or 2 and Alk denotes a straight or branched alkylene chain of 1 to 6 carbon atoms. The compounds have therapeutic activity. Further disclosed are the corresponding primary amines of the formula ##STR4## from which the above compounds may be prepared by introducing the group ##STR5##
揭示了一般公式为##STR1##的化合物及其生理上可接受的盐、水合物和生物前体,其中R.sub.1和R.sub.2,可以相同也可以不同,代表氢、较低烷基、环烷基、芳基烷基或较低烯基基团,这些烷基基团可以被氧原子或基团##STR2##中断,其中R.sub.4代表氢或较低烷基;或者R.sub.1和R.sub.2可以与它们连接的氮原子一起形成一个可以包含其他异杂环功能的杂环,所述其他异杂环功能从--O--和##STR3##中选择;R.sub.3代表氢、较低烷基、较低烯基或烷氧基烷基;X代表--O--、--S--或--CH.sub.2--;Y代表.dbd.S、.dbd.O、.dbd.NR.sub.5或.dbd.CHR.sub.6;其中R.sub.5为氢、硝基、氰基、较低烷基、芳基、烷基磺酰基或芳基磺酰基,R.sub.6代表硝基、烷基磺酰基或芳基磺酰基;m为2至4的整数;n为1或2或者当X为S或CH.sub.2时,n为零、1或2,Alk表示1至6个碳原子的直链或支链烷基链。这些化合物具有治疗活性。还披露了相应的一般式为##STR4##的初级胺,通过引入基团##STR5##可以制备上述化合物。
