Novel nitrogen-containing heterocyclic compounds shown by the formula ##STR1## wherein one of R.sub.1 and R.sub.2 represents a lower alkyl group, a phenyl group, a halophenyl group, or a lower alkoxyphenyl group and the other of them represents a hydrogen atom, a lower alkyl group, or a phenyl lower alkyl group; said R.sub.1 and R.sub.2 may combine with each other to form a trimethylene group or a tetramethylene group; R.sub.3 represents a hydrogen atom, a lower alkyl group, a phenyl group, or a phenyl lower alkyl group; X represents an oxygen atom, a sulfur atom, an imino group, or a group shown by ##STR2## (wherein m represents 1 or 2 and R.sub.4 represents a lower alkyl group, a hydroxy lower alkyl group, a cycloalkyl group or a phenyl lower alkyl group); and Y represents an ethylene group which may be substituted by lower alkyl group, a trimethylene group, a tetramethylene group, a vinylene group which may be substituted by a lower alkyl group, or ##STR3## (wherein R.sub.5 represents a hydrogen atom, a lower alkyl group, a trifluoromethyl group, or a phenyl group); said X is the group shown by ##STR4## when one of said R.sub.1 and R.sub.2 is a lower alkyl group and the other is a hydrogen atom, and said Y is an ethylene group, and the pharmacologically acceptable non-toxic salts thereof. The compounds described above are strong analgesic anti-inflammatory agents.
根据下面的公式所示的新型含氮杂环化合物,其中R.sub.1和R.sub.2中的一个代表低烷基基团、苯基、卤苯基或低烷氧基苯基,另一个代表氢原子、低烷基基团或苯低烷基基团;所述的R.sub.1和R.sub.2可以结合在一起形成三亚甲基基团或四亚甲基基团;R.sub.3代表氢原子、低烷基基团、苯基或苯低烷基基团;X代表氧原子、硫原子、亚胺基团或由##STR2##所示的基团(其中m代表1或2,R.sub.4代表低烷基基团、羟基低烷基基团、环烷基团或苯基低烷基基团);Y代表乙烯基,可以被低烷基基团、三亚甲基基团、四亚甲基基团、乙烯基取代,或者##STR3##(其中R.sub.5代表氢原子、低烷基基团、三氟甲基基团或苯基);当R.sub.1和R.sub.2中的一个是低烷基基团,另一个是氢原子时,X是由##STR4##所示的基团,Y是乙烯基,以及其药理学上可接受的无毒盐。上述描述的化合物是强效的镇痛抗炎药物。
