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, R1: an oxygen-containing saturated hetero ring or the like, Alk1: a lower alkylene, m: 0 or 1, Alk2: a lower alkylene which may be substituted with oxo group, n: 0 or 1, X: a bond, O, S or NR5, R3: H or the like, and R2, R4, R5, R6 and R7: the same or different from one another and each represents H or the like.
Provided that R3 does not represent a lower alkyl or a halogeno-lower alkyl when X is a bond and n is 1. Also, R4 represents a group other than Me when m is 1, R1 is OH or OMe and Alk1 is a C1-3 alkylene, and further 1) when X is a bond, n is 1 and R3 is H, or 2) when X is a bond, n is 0 and R3 is cyclohexane.)
本发明涉及一种新型的
氨甲基取代的
噻唑苯并咪唑衍
生物,其通式如下(I),或其盐。上述衍
生物或其盐具有代谢型谷
氨酸受体作用和优异的口服活性,因此可用作药物。(在公式中,R1:氧含量饱和杂环等,Alk1:低级烷基,m:0或1,Alk2:可能被氧代基取代的低级烷基,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,且每个代表H或类似物。前提是当X为键且n为1时,R3不代表低级烷基或卤代低级烷基。此外,当m为1,R1为OH或OMe,Alk1为C1-3烷基时,R4代表Me以外的基团,且进一步1)当X为键,n为1且R3为H时,或2)当X为键,n为0且R3为
环己烷时,R4代表其他基团。)
