of magnitude higher affinity for the receptors than diazepam. Planarity was one of the structural requirements for binding to benzodiazepine receptors. The activities of agonists and inverse agonists were assessed on the basis of inhibition or facilitation of the pentylenetetrazole-induced convulsions, respectively. Thien-3-yl compounds exhibited inverse agonist activity whereas thien-2-yl analogues
一系列2-(thien-3-yl)-和2-(thien-2-yl)-2,5-dihydro-3H-pyrazolo [4,3-c] quinolin-3的合成及构效关系-报告一个。与地西epa相比,许多化合物对受体的亲和力高1个数量级。平面度是与苯并二氮杂receptor受体结合的结构要求之一。激动剂和反向激动剂的活性分别基于戊烯四唑诱导的惊厥的抑制或促进进行评估。噻吩-3-基化合物表现出反向激动剂活性,而具有5'-烷基的噻吩-2-基类似物表现出激动剂活性。喹啉部分上的取代不增强体内活性。
