The synthesis of some new 1,2,3,5,6,7‐hexahydro‐2,5,6‐tri‐oxopyrazino[ 1,2,3‐de]quinoxalines 1c—g and of their restricted analogs 2,4,5,6‐tetrahydro‐2,5‐dioxo‐1H‐ 2a—g and 5,6‐dihydro‐4, 5‐dioxo‐4H‐imidazo[1,5,4‐de]quinoxalines 3a—d is reported. Compounds 1c—g, 2a—g, and 3a—d were tested for their binding activity at the glycine/NMDA and AMPA receptors. The results show that only the 6,6,6‐tricyclic
一些新的 1,2,3,5,6,7-hexahydro-2,5,6-tri-oxopyrazino [1,2,3-de] quinoxalines 1c-g 及其限制性类似物 2,4 的合成,报道了 5,6-四氢-2,5-二氧-1H-2a-g 和 5,6-二氢-4, 5-二氧-4H-咪唑并 [1,5,4-de] 喹喔啉 3a-d。测试化合物1c-g、2a-g和3a-d对甘氨酸/NMDA和AMPA受体的结合活性。结果表明,只有 6,6,6-三环衍生物 1c-g 能够与甘氨酸/NMDA 和 AMPA 受体结合,尽管其亲和力低于先前报道的先导化合物 1a-b。相比之下,5,6,6-三环衍生物 2a-g 对两种受体均无活性,只有一种 4,5-二氧咪唑并喹喔啉 (3b) 显示出弱甘氨酸/NMDA 受体亲和力。
