ethers were conjugated with three ligand series for nicotinic acetylcholine receptors. Conjugates of acetylaminocholine, the cyclic analog 1-acetyl-4,4-dimethylpiperazinium, and pyridyl ether A-84543 were prepared. Each series was found to retain significant affinity at nicotinic receptors in rat cerebral cortex with tethers of up to six PEG units. Such compounds are hydrophilic ligands which may serve
一系列同源聚乙二醇(PEG)单甲醚与烟碱乙酰胆碱受体的三个配体系列缀合。制备了乙酰氨基胆碱、环状类似物 1-乙酰基-4,4-二甲基哌嗪鎓和吡啶基醚 A-84543 的缀合物。发现每个系列都对大鼠大脑皮层中的烟碱受体保持显着的亲和力,并具有多达六个 PEG 单元的系链。此类化合物是亲水性配体,可用作荧光/亲和探针和 nAChR 多价配体的模型。
