The present invention relates to compounds represented by the following general formula (
1
):
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.
本发明涉及以下通式(1)所表示的化合物:
其中,A是苯基、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,可以被取代;X是可以被取代的低碳链基或类似物;Y是单键或碳链基;Z是—CH═CH—、—C≡C—、—(CH═CH)2-、—C≡C—CH═CH—或—CH═CH—C≡C—等基团或类似物;R是氢原子、低碳基或类似物,以及包含这种化合物的药物。这些化合物对IgE抗体的产生具有优异的抑制作用,因此可用作抗过敏药物等。
