indicative of partial agonist actions. Like spermine, the ability of these piperazine and homopiperazine derivatives to enhance [3H]MK-801 binding could be inhibited by both a competitive polyamine antagonist (arcaine) and a specific, noncompetitive polyamine antagonist (conantokin-G). However, unlike endogenous polyamines, high concentrations (up to 1 mM) of these novel polyamine-like compounds did not inhibit
为了产生与N-甲基-D-天冬氨酸盐(NMDA)受体上的多胺调节位点相互作用的化合物,已经合成了一系列N,N′-取代的哌嗪和高哌嗪衍生物。这些新颖的化合物表现出类似多胺的作用,增强了大鼠前脑膜中[3H] MK-801与NMDA受体的结合。N,N'-双(2-氨基乙酰基)高哌嗪(15),N,N'-双(N-甲基-4-氨基丁基)-哌嗪(7)和N,N'-双(3-氨丙基)高哌嗪(11)(分别为EC50 18.0、21.3和24.4 microM)增强[3H] MK-801结合,与精胺(EC50 5.2 microM)相当。但是,在该方法中,15、7和11的功效低于精胺(分别降低约40%,32%和24%),这可能表明存在部分激动剂作用。像精胺一样 这些哌嗪和高哌嗪衍生物增强[3H] MK-801结合的能力可能会被竞争性多胺拮抗剂(arcaine)和特定的非竞争性多胺拮抗剂(conantokin-G)抑制。
