A series of N,N-disubstituted piperazines were prepared and evaluated for binding to alpha4beta2(*) and alpha7(*) neuronal nicotinic acetylcholine receptors using rat striatum and whole brain membrane preparations, respectively. This series of compounds exhibited selectivity for alpha4beta2(*) nAChRs and did not interact with the alpha7(*) nAChRs subtype. The most potent analogues were compounds 8b
制备了一系列N,N-二取代哌嗪,并分别使用大鼠纹状体和全脑膜制剂评估了与α4β2(*)和α7(*)神经元烟碱乙酰胆碱受体的结合。这一系列的化合物表现出对alpha4beta2(*)nAChRs的选择性,并且不与alpha7(*)nAChRs亚型相互作用。最有效的类似物是化合物8b和8f(K(i)= 32 microM)。因此,通过哌嗪环将吡啶pi系统和环胺部分连接在一起,可提供具有低亲和力但对α4beta2(*)烟碱受体具有良好选择性的化合物。
