The present invention provides a novel compound exhibiting an excellent inhibitory action on AMPA receptor and/or kainate receptor. That is, it provides a compound represented by the following formula, a salt thereof or a hydrate of them.
In the formula, A1, A2 and A3 are independent of each other and each represents a C3-8 cycloalkyl group, a C3-8 cycloalkenyl group, a 5- to 14-membered non-aromatic heterocyclic group, a C6-14 aromatic hydrocarbon cyclic group or a 5- to 14-membered aromatic heterocyclic group, each of which may be substituted; Q represents O, S or NH; Z represents C or N; X1, X2 and X3 are independent of each other and each represents a single bond, an optionally substituted C1-6 alkylene group, an optionally substituted C2-6 alkenylene group, an optionally substituted C2-6 alkynylene group, -NH-, -O-, -NHCO-, -CONH-, -SO0-2-, etc.; R1 and R2 are independent of each other and each represents a hydrogen atom or an optionally substituted C1-6 alkyl group, or R1 and R2 may be bound together such that CR2-ZR1 forms C=C; and R3 represents a hydrogen atom or an optionally substituted C1-6 alkyl group etc., or may be bound to any atom in A1 or A3 to form, together with the atom, an optionally substituted C5-8 hydrocarbon ring or an optionally substituted 5- to 8-membered heterocyclic ring.
本发明提供了一种对 AMPA 受体和/或 kainate 受体具有良好抑制作用的新型化合物。也就是说,本发明提供了由下式代表的化合物、其盐或它们的水合物。
式中,A1、A2 和 A3 相互独立,各自代表 C3-8 环烷基、C3-8 环烯基、5-14 元非芳香杂环基、C6-14 芳香烃环基或 5-14 元芳香杂环基,其中每个基团都可以被取代;Q代表O、S或NH; Z代表C或N; X1、X2和X3彼此独立,各自代表单键、任选取代的C1-6亚烷基、任选取代的C2-6亚烯基、任选取代的C2-6亚炔基、-NH-、-O-、-NHCO-、-CONH-、-SO0-2-等。R1 和 R2 相互独立,各自代表氢原子或任选取代的 C1-6 烷基,或 R1 和 R2 可结合在一起,使 CR2-ZR1 形成 C=C;R3 代表氢原子或任选取代的 C1-6 烷基等、或可与 A1 或 A3 中的任一原子结合,与该原子一起形成任选取代的 C5-8 碳氢环或任选取代的 5-8 元杂环。
