The (Z) and (E) pairs of 5-aminopent-2-enoic acid and 5-aminopent-3- enoic acid, as well as the related 5-aminopent-3-ynoic acid, have been prepared for structure-activity studies on GABA receptors. Only the (Z) isomers were active as GABA agonists with (Z)-5-aminopent-2-enoic acid being two- to four-fold more active than 5-aminopentanoic acid.
我们制备了 5-aminopent-2-enoic acid 和 5-aminopent-3- enoic acid 的 (Z) 和 (E) 对异构体,以及相关的 5-aminopent-3-ynoic acid,用于 GABA 受体的结构-活性研究。只有 (Z) 异构体作为 GABA 激动剂具有活性,其中 (Z)-5-aminopent-2-enoic acid 的活性是 5-aminopentanoic acid 的 2 到 4 倍。
