The synthesis of new 3-heteroaryl-8-chloropyrazolo[5,1-c][1,2, 4]benzotriazine 5-oxides and their binding activities at the central benzodiazepine receptor (BZR) are reported. The derivatives substituted at the 3-position with electron-rich five-membered rings, such as pyrrole 11, 2-thiophene 13c, or 3-thiophene 13d, showed good affinity values for BZR. In in vivo tests the 3-(thien-3-yl)-8-chloropyrazolo[5
报道了新的3-杂芳基-8-氯吡唑并[5,1-c] [1,2,4]苯并三嗪5-氧化物的合成及其在中央苯并二氮杂receptor受体(BZR)上的结合活性。在3位上被富电子的五元环取代的衍生物,例如吡咯11、2-噻吩13c或3-噻吩13d,显示出对BZR良好的亲和力值。在体内试验中,3-(thien-3-yl)-8-chloropyrazolo [5,1-c] [1,2,4]苯并三嗪5氧化物(13d)显示出选择性的抗惊厥活性。
