A series of 4-(piperidin-4-yl)-1-hydroxypyrazole (4-PHP) 3- or 5-imidazolyl substituted analogues have been designed, synthesized, and characterized pharmacologically. All analogues showed binding affinities in the low micro- to low nanomolar range at native rat GABAA receptors and were found to be antagonists at the human α1β2γ2s receptor. The structure–activity relationship of the compound series
已经设计,合成和表征了一系列4-(哌啶-4-基)-1-羟基吡唑(4-PHP)3-或5-咪唑基取代的类似物。所有的类似物表现出结合亲和力的低微以低纳摩尔范围在天然大鼠GABA甲受体和被认为是在人α拮抗剂1 β 2 γ 2S受体。该化合物系列的结构-活性关系表明,在正构结合位点4-PHP支架附近,先前发现的腔在大小和结构上存在明显差异。
