The present invention relates to compounds of formula I:
in which R1 is a linear group or a five membered heterocycle optionally fused to a phenyl ring, R2 is a 5-membered heterocycle, R3 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.
本发明涉及公式I的化合物:其中R1是线性基团或五元杂环,可选地融合到苯环上,R2是五元杂环,R3从一系列取代基中选择,m为0-3,n为0或1;这些化合物通常是GABA-A受体的反向激动剂,包含α5亚基,因此在增强认知的方法中对于认知减退的疾病如阿尔茨海默病的患者是有用的。
