None of these derivatives are as potent or selective as 5, although some do display a degree of selectivity as antagonists. Some derivatives were found to possess agonist properties that, with the exception of 23, favored the postsynaptic site. Compounds 9, 12, 16, 21, 30, and 51 possessing presynaptic alpha 2-adrenoreceptor antagonist and postsynaptic alpha 1-adrenoreceptor partial agonist properties
讨论了RX 781094,2-(1,4-苯并二恶烷-2-基)-2-咪唑啉盐酸盐(5)的合理设计,该化合物是新型的α2-肾上腺素受体有效和选择性拮抗剂。在突触前α2肾上腺素受体上起拮抗剂作用的化合物可能是有效的新型抑郁症治疗方法,因为它具有增加中央受体部位去甲肾上腺素浓度的能力。已经研究了芳族和咪唑啉环中取代基的作用,以及用examined官能团或其他杂环系统取代咪唑啉环的作用。尽管有些衍生物确实表现出一定程度的拮抗剂,但这些衍生物都不像5那样有效或具有选择性。发现一些衍生物具有激动剂特性,除23种外,它们更有利于突触后位点。化合物9
