A series of N-substituted imidazolines and ethylenediamines were synthesized and examined for their activity in alpha- and beta-adrenergic systems. The length of the intermediate side chain between the catechol and imidazoline ring or the amine of the ethylenediamine segment was shown to affect the adrenergic activity. N-[2-(3,4-Dihydroxyphenyl)ethyl]imidazoline hydrochloride (2) and N-[2-(3,4-dih
合成了一系列的N-取代的咪唑啉和乙二胺,并检查了它们在α-和β-肾上腺素系统中的活性。儿茶酚和咪唑啉环或乙二胺链段的胺之间的中间侧链的长度显示影响肾上腺素能活性。N- [2-(3,4-二羟基苯基)乙基]咪唑啉盐酸盐(2)和N- [2-(3,4-二羟基苯基)乙基]乙二胺盐酸盐(4),两者在儿茶酚和胺之间均具有两个亚甲基被发现对α2-肾上腺素受体有些选择性,而1-(3,4-二羟基苄基)咪唑啉盐酸盐(1)和N-2-(3,4-二羟基苄基)乙二胺二盐酸盐(3)儿茶酚和胺链段之间的亚甲基,在有髓大鼠模型中对α1-肾上腺素受体的选择性更高。在所研究的四种化合物中,只有化合物2对β1和β2肾上腺素能受体具有明显的直接活性。
