With the aim to develop new ligands able to discriminate among the three subtypes of alpha1-adrenergic receptors (alpha1A-AR, alpha1B-AR, and alpha1D-AR), a series of new 1,2,3,9-tetrahydro-4H-carbazol-4-ones bearing a 3-[[[2-(4-hydroxyphenyl)ethyl]amino]methyl] or a 3-[[4-(2-substitutedphenyl)piperazin-1-yl]methyl] side chain were synthesized. The general structure of the new compounds is reminiscent
为了开发能够区分α1-肾上腺素受体的三种亚型(α1A-AR,α1B-AR和α1D-AR)的新配体,一系列新的1,2,3,9-tetrahydro-4H-合成带有3-[[[[(2-(4-羟基苯基)乙基]氨基]甲基]或3-[[4-(2-取代苯基)哌嗪-1-基]甲基]侧链的咔唑-4-酮。新化合物的一般结构使人联想到HEAT和RN5,这是两种有效的α1-AR拮抗剂,它们对所有三种α1-AR亚型都表现出高亲和力。还制备了其中四氢咔唑酮系统的一个环打开的一些衍生物。在人类HEK293细胞中稳定表达的人类克隆的alpha1A-AR,alpha1B-AR和alpha1D-AR亚型的放射性配体结合试验中测试了化合物。他们表现出中等至良好的亲和力,
