An object of the present invention is to provide a novel AMPA receptor potentiator.
A compound represented by the following formula (I) or a salt thereof:
wherein in formula (I)
R
1
represents
(1) a halogen atom, or (2) cyano group, or the like;
Ra and Rb each independently represent a hydrogen atom or C
1-4
alkyl;
L represents a bond, or a spacer in which the number of atoms in the main chain is 1 to 8;
Ring A represents
(1) a non-aromatic carbon ring of 4-8 carbon atoms, or
(2) a 4- to 8-membered non-aromatic heterocycle
either of which is optionally substituted with 1 or more substituents selected from
(a) halogen atoms, and (b) cyano group; and
Ar represents
a substituted phenyl group, or
optionally substituted 5- or 6-membered aromatic heterocyclic group.
本发明的目的是提供一种新型AMPA受体增强剂。化合物由以下式(I)或其盐所表示:其中在式(I)中,R1表示(1)卤素原子或(2)氰基等;Ra和Rb各自独立地表示氢原子或C1-4烷基;L表示键或主链中原子数为1至8的间隔物;环A表示(1)4-8个碳原子的非芳香碳环,或(2)4-至8个成员的非芳香杂环,其中任一环均可以选择性地用1个或多个取代基所取代,所述取代基选择自(a)卤素原子和(b)氰基;Ar表示取代苯基或可选择性取代的5-或6-成员芳香杂环基。
