the very few chemical families which exhibit high to moderate potency for DI GABAA receptors. Although imidazobenzodiazepines such as Ro 15-4513, 20, are the most potent DI GABAA receptor ligands described to date, their selectivity for DI versus DS GABAA receptors is only marginal. Previous structure-activity relationship (SAR) studies of imidazobenzodiazepines have indicated that the 3- and 8-positions
描述了一系列新型咪唑并苯并二氮杂pine的合成及其对地西epa敏感(DS)和地西epa不敏感(DI)GABAA受体的亲和力。咪唑并苯二氮杂类是极少数对DI GABAA受体表现出高至中等效力的化学家族之一。尽管咪唑并二氮杂卓类(例如Ro 15-4513,20)是迄今为止描述的最有效的DI GABAA受体配体,但它们对DI与DS GABAA受体的选择性仅很小。先前对咪唑并苯并二氮杂卓的结构活性关系(SAR)研究表明,3位和8位对于与DI GABAA受体的高亲和力结合至关重要(J. Med。Chem。1993,36,479-490。J. Med J. Med。Chem。1993,36,1001-1006。J. Med。Chem。1993,36,1820-1830)。为了确定酯功能为何对DI位的高亲和力至关重要,我们合成了几种衍生物,这些衍生物在C(3)位置的酯以外具有取代基,包括3-烷基-,3-
