We report the synthesis and binding activity to the central benzodiazepine receptors of some 2,3-dihydro-2-aryl-4-R-[1]benzopyrano[4,3-c]pyrazole-3-ones, which are isosteres of the CGS series. Although the compounds of the CGS series are potent ligands of the benzodiazepine receptors, none of the isosteres tested showed any significant inhibiting potency. This may be due to the change in electronic
我们报告的合成和结合活性对一些2,3-二氢-2-芳基-4-R- [1]苯并吡喃并[4,3-c]吡唑-3-酮的中央苯并二氮杂receptor受体,它们是CGS系列。尽管CGS系列化合物是苯并二氮杂receptor受体的有效配体,但所测试的等位基因均未显示任何明显的抑制作用。这可能是由于用氧原子代替CGS系列的NH所引起的电子性能变化。
