Methylated analogues of imidazoline related compounds (IRC) were prepared; their abilities to bind I1 imidazoline receptors (I1Rs), I2 imidazoline binding sites (I2BS) and α2-adrenoceptor subtypes (α2ARs) were assessed. Methylation of the heterocyclic moiety of IRC resulted in a significant loss of α2AR affinity. Amongst the selective ligands obtained, LNP 630 (4) constitutes the first highly selective
制备了咪唑啉相关化合物的甲基化类似物(IRC);自己的能力我结合1个咪唑啉受体(I 1 RS),我2个咪唑啉结合位点(I 2 BS)和α 2 -肾上腺素能受体亚型(α 2 ARS)进行了评估。IRC的杂环部分的甲基化导致α的显著损失2 AR的亲和力。在获得的选择性配体中,LNP 630(4)构成第一种高选择性I 1 R剂,在静脉内给药后表现出降压活性。
