A class of substituted imidazolo[5,1-a]phthalazine derivatives as ligands for GABA
A
receptors of formula I
which are partial or full inverse agonists of an α5 receptor subunit while being relatively free of activity at α1 and/or α2 and/or α3 receptor subunit binding sites are described herein; they are therefore of benefit as a medicament for enhancing cognition but with the reduction or elimination of proconvulsant activity.
本文描述了一类化合物,它们是公式I中的取代咪唑并[5,1-a]菲噻嗪衍生物,作为GABAA受体的配体,是α5受体亚单位的部分或完全反向激动剂,同时在α1和/或α2和/或α3受体亚单位结合位点上相对缺乏活性。因此,它们作为一种药物有益于增强认知能力,但减少或消除促痫性活性。
