evaluated for their ability to inhibit [3H]dopamine (DA) uptake at the vesicular monoamine transporter-2 (VMAT2) and dopamine transporter (DAT), [3H]serotonin (5-HT) uptake at the serotonin transporter (SERT), and [3H]dofetilide binding at the human-ether-a-go-go-related gene (hERG) channel. The majority of the compounds exhibited potent inhibition of [3H]DA uptake at VMAT2, Ki changes in the nanomolar
设计,合成和评估了氟乙氧基-1,4-二苯乙基哌啶和氟乙氧基-1,4-二苯乙基哌嗪的小型文库,它们在水泡单胺转运蛋白2上抑制[ 3 H]多巴胺(DA)吸收的能力( VMAT2)和多巴胺转运蛋白(DAT),5-羟色胺转运蛋白(SERT)的[ 3 H] 5-羟色胺(5-HT)摄取以及人-醚-去-相关基因的[ 3 H] dofetilide结合( hERG)频道。大多数化合物在 VMAT2上显示出对[ 3 H] DA吸收的有效抑制,Ki在纳摩尔范围内变化(K i = 0.014-0.073 µM)。化合物15d表现出最高的亲和力(K i VMAT2的选择性为0.014 µM),对VMAT2的选择性分别比DAT,SERT和hERG高160倍,5倍和60倍。相对于所有其他评估目标,化合物15b对VMAT2表现出最大的选择性(> 60倍),而15b对VMAT2具有高亲和力(K i = 0.073 µM
