The present invention relates to compounds represented by the following general formula (1):
wherein A is a phenyl, naphthyl, dihydronaphthyl, indenyl, pyridyl, indolyl, isoindolyl, quinolyl or isoquinolyl group which may be substituted; X is a lower alkylene group which may be substituted, or the like; Y is a single bond or an alkylene group; Z is a group of -CH=CH-, -C≡C-, -(CH=CH)2-, -C≡C-CH=CH- or -CH=CH-C≡C-, or the like; and R is a hydrogen atom, a lower alkyl group or the like, and medicines comprising such a compound. These compounds have an excellent inhibitory effect on the production of an IgE antibody and are hence useful as antiallergic agents and the like.
本发明涉及由以下通式(1)代表的化合物:
其中 A 是可被取代的
苯基、
萘基、二
氢萘基、
茚基、
吡啶基、
吲哚基、异
吲哚基、
喹啉基或
异喹啉基;X 是可被取代的低级亚烷基或类似基团;Y是单键或亚烷基;Z是-CH=CH-、-C≡C-、-(CH=CH)2-、-C≡C-CH=CH-或-CH=CH-C≡C-或类似基团;R是
