This invention relates to the provision of novel aminomethyl-substituted thiazolobenzimidazole derivatives represented by the following general formula (I) or a salt thereof.
The aforementioned derivative or a salt thereof has a metabotropic glutamate receptor action and excellent oral activity and is therefore useful as a medicament.
(In the formula, R
1
: an oxygen-containing saturated hetero ring or the like, Alk
1
: a lower alkylene, m: 0 or 1, Alk
2
: a lower alkylene which may be substituted with oxo group, n: 0 or 1, X: a bond, O, S or NR
5
, R
3
: H or the like, and R
2
, R
4
, R
5
, R
6
and R
7
: the same or different from one another and each represents H or the like.
Provided that R
3
does not represent a lower alkyl or a halogeno-lower alkyl when X is a bond and n is 1. Also, R
4
represents a group other than Me when m is 1, R
1
is OH or OMe and Alk
1
is a C
1-3
alkylene, and further 1) when X is a bond, n is 1 and R
3
is H, or 2) when X is a bond, n is 0 and R
3
is cyclohexane.)
本发明涉及提供以下一般式(I)或其盐所表示的新型氨甲基取代噻唑苯并咪唑衍生物。上述衍生物或其盐具有代谢型谷氨酸受体作用和良好的口服活性,因此可用作药物。其中,R1:含氧饱和杂环或类似物,Alk1:较低的烷基,m:0或1,Alk2:较低的烷基,可以用氧代基取代,n:0或1,X:键,O,S或NR5,R3:H或类似物,R2,R4,R5,R6和R7:相同或不同,每个代表H或类似物。前提是当X是键且n为1时,R3不代表较低的烷基或卤代较低的烷基。此外,当m为1时,R4代表除Me以外的基团,R1为OH或OMe,Alk1为C1-3烷基,进一步1)当X是键,n为1且R3为H时,或2)当X是键,n为0且R3为环己烷时。
