and pyrazolo[3,4‐c]‐quinoline‐1,4‐diones 15–17 were prepared and biologically evaluated for their binding at the benzodiazepine receptor (BZR) in rat cortical membranes. The moderate binding activity of 1–5,7,9–10, 13 is attributable to the lack of the optional proton acceptor at position‐1, while the inactivity of the 1,4‐dione derivatives 15–17 is due to the lack of the essential proton acceptor at
制备了一些吡唑并 [3,4 - c] 喹啉 - 4 - 1-14 和吡唑并 [3,4 - c] - 喹啉 - 1,4 - 二酮 15-17,并对其与苯二氮卓受体的结合进行了生物学评估。 BZR) 在大鼠皮层膜中。1-5,7,9-10,13 的中等结合活性归因于在 1 位缺乏可选的质子受体,而 1,4-二酮衍生物 15-17 的无活性是由于缺乏3 位必需的质子受体。这些结论证实了我们提出的药效模型的有效性。
