Arylpiperazines 2–11 were synthesized, and their biological profiles at α1-adrenergic receptors (α1-ARs) assessed by binding assays in CHO cells expressing human cloned subtypes and by functional experiments in isolated rat vas deferens (α1A), spleen (α1B), and aorta (α1D). Modifications at the 1,3-benzodioxole and phenyl phamacophoric units resulted in the identification of a number of potent compounds
芳基哌嗪2 - 11合成,和它们在通过结合表达人克隆亚型的CHO细胞测定法评估α1肾上腺素能受体(α1-ARS),并通过在分离的大鼠输精管功能性实验(α1A),脾(α1B)生物型材,和主动脉(α1D)。在结合实验中,对1,3-苯并二恶唑和苯基正电单元的修饰导致鉴定出许多有效的化合物(相对于α1b-AR具有中等选择性)。值得注意的是,化合物7(LDT451)显示出亚纳摩尔p K i朝向α1a-AR的9.41。对于所有系列化合物而言,令人鼓舞的是较低的α1B效能是一个总体趋势,在功能测定中,α1A/ D的选择性超过了α1B的选择性。如果充分优化,这种特殊的选择性可能与潜在的LUTS / BPH治疗应用有关。
