  作为潜在镇咳剂的新型 α7 烟碱型乙酰胆碱受体调节剂

  摘要：

  设计了一系列新的 α7 烟碱型乙酰胆碱受体 (nAChR) 调节剂，并评估了其在体内化学诱发咳嗽的豚鼠模型中的镇咳活性。所有测试剂量（9.5、3 和 1 mg/kg）的化合物16显着（p < 0.01）减少咳嗽的累积次数，并显示与阳性对照（30 mg/kg 的可待因）相似的结果。在三种不同的给药途径（腹膜内、口服和吸入）中，化合物16在吸入剂量低至 0.4 mg/kg 时对豚鼠产生显着的镇咳作用 ( p < 0.05)。α7 nAChR 调节剂可为急性和慢性咳嗽患者提供一种新型的非麻醉性治疗方法。

  2-(Arylmethyl)-3-substituted quinuclidines as selective α7 nicotinic receptor ligands

  摘要：

  A series of 2-(arylmethyl)-3-substituted quinuclidines was developed as alpha 7 neuronal nicotinic acetylcholine receptor (nAChR) agonists based on a putative pharmacophore model. The series is highly selective for the alpha 7 over other nAChRs (e.g., the alpha A beta 2 of the CNS, and the muscle and ganglionic subtypes) and is functionally tunable at alpha 7. One member of the series, (+)-N-(1-azabicyclo[2.2.2]oct-3-yl)benzo[b]furan-2-carboxamide (+)-81), has potent agonistic activity for the alpha 7 nAChR (EC50 = 33 nM, I-max = 1.0), at concentrations below those that result in desensitization.

• Surface Plasmon Resonance Biosensor Based Fragment Screening Using Acetylcholine Binding Protein Identifies Ligand Efficiency Hot Spots (LE Hot Spots) by Deconstruction of Nicotinic Acetylcholine Receptor α7 Ligands

  The soluble acetylcholine binding protein (AChBP) is a homologue of the ligand-binding domain of the nicotinic acetylcholine receptors (nAChR). To guide future fragment-screening using surface plasmon resonance (SPR) biosensor technology as a label-free, direct binding, biophysical screening assay, a focused fragment library was generated based on deconstruction of a set of alpha 7 nAChR selective quinuclidine containing ligands with nanomolar affinities. The interaction characteristics of the fragments and the parent compounds with AChBP) were evaluated using an SPR biosensor assay. The data obtained from this direct binding assay correlated well with data from the reference radioligand displacement assay. Ligand efficiencies for different (structural) groups of fragments in the library were correlated to binding with distinct regions of the binding pocket, thereby identifying ligand efficiency hot spots (LE hot spots). These hot spots can be used to identity the most promising hit fragments in a large scale fragment library screen.
