The novel water-soluble N-methyl-D-aspartate (NMDA) receptor antagonists, N-4-[4-(4-Guanidinobutylamino)butylamino]butyl}-p-toluenesulfonamide trihydrochloride (1a, TsHSPMG), N-4-[4-(4-Guanidinobutylamino)butylamino]butyl}butane-1-sulfonamide trihydrochloride (1b, BsHSPMG), N-3-[4-(3-Guanidinopropylamino)butylamino]propyl}-p-toluenesulfonamide trihydrochroride (2a, TsSPMG) and N-3-[4-(3-Guanidinopropylamino)butylamino]propyl}butane-1-sulfonamide trihydrochroride (2b, BsSPMG), were synthesized, and the effects of these polyamine derivatives on NMDA receptors were studied using voltage-clamp recordings of recombinant NMDA receptors expressed in Xenopus oocytes. Although spermine potentiates 153% and 310% of NMDA (NR1A/NR2B) receptors in the presence of saturated and unsaturated glycine, respectively, all the novel polyamine derivatives, TsHSPMG (1a), BsHSPMG (1b), TsSPMG (2a) and BsSPMG (2b), significantly inhibited NR1A/NR2B receptors in both conditions. The degree of NMDA receptor inhibition by TsHSPMG (1a) and BsHSPMG (1b) was stronger than that by TsSPMG (2a) and BsSPMG (2b).
新型水溶性 N-甲基-<小>D小>-天冬氨酸(NMDA)受体拮抗剂 N-4-[4-(4-胍基丁基氨基)丁基氨基]丁基}对甲苯磺酰胺三盐酸盐(1a,TsHSPMG)、N-4-[4-(4-胍基丁基氨基)丁基氨基]丁基}丁烷-1-磺酰胺三盐酸盐(1b,BsHSPMG)、N-3-[4-(3-胍基丙基氨基)丁基氨基]丙基}对甲苯磺酰胺三氢化物(2a、合成了 N-3-[4-(3-胍基丙基氨基)丁基氨基]丙基}丁烷-1-磺酰胺三氢镜像物(2b,BsSPMG),并使用在爪蟾卵母细胞中表达的重组 NMDA 受体的电压钳记录研究了这些多胺衍生物对 NMDA 受体的影响。尽管精胺在饱和甘氨酸和不饱和甘氨酸存在下可分别增强 153% 和 310% 的 NMDA(NR1A/NR2B)受体,但所有新型多胺衍生物 TsHSPMG (1a)、BsHSPMG (1b)、TsSPMG (2a) 和 BsSPMG (2b) 在这两种条件下都能显著抑制 NR1A/NR2B 受体。TsHSPMG (1a) 和 BsHSPMG (1b) 对 NMDA 受体的抑制程度强于 TsSPMG (2a) 和 BsSPMG (2b)。
