The present invention relates to compounds of formula I:
1
in which R
1
is a linear group or a five membered heterocycle optionally fused to a phenyl ring, R
2
is a 5-membered heterocycle, R
3
is chosen from a range of substituents, m is 0-3 and n is 0 or 1; the compounds are generally inverse agonists at GABA-A receptors containing the alpha 5 subunit and so are useful in methods of enhancing cognition in subjects with diminished cognition in diseases such as Alzheimer's Disease.
本发明涉及式I的化合物:其中R1是线性基团或者一个五元杂环,可选择地与苯环融合,R2是一个五元杂环,R3是从一系列取代基中选择的,m为0-3,n为0或1;这些化合物通常是GABA-A受体中含有α5亚基的逆激动剂,因此在增强认知的方法中对患有认知减退症如阿尔茨海默病的受试者是有用的。
