Two new potent AMPA receptor allosteric modulators, 6-(1,3-benzodioxol-5-yl)-1,11-dimethyl-3,6,9-triazatri-cyclo[7.3.1.13,11]tetradecane-4,8,12-trione and -4,8-dione were synthesized from 1,3-benzodioxol-5-amine and the corresponding 3,7-dichloroacetyl-3,7-diazabicyclo[3.3.1]-nonanes. In a wide concentration range (10−12–10−7 m), the 12-oxo derivative acts as a positive modulator causing the potentiation
两种新的强效 AMPA 受体变构调节剂,6-(1,3-benzodioxol-5-yl)-1,11-dimethyl-3,6,9-triazatri-cyclo[7.3.1.1 3,11 ]tetradecane-4,8 ,12-trione 和 -4,8-dione 由 1,3-benzodioxol-5-amine 和相应的 3,7-dichloroacetyl-3,7-diazabicyclo[3.3.1]-nonanes 合成。在较宽的浓度范围(10 -12 –10 -7 m)中,12-氧代衍生物作为正调节剂,导致红藻氨酸诱导的 AMPA 受体电流增强,最大增强在 1 nm (62%),而其类似物没有酮基具有显着(高达 40%)的负调节作用。通过分子模型分析了它们的初步作用机制
