This invention relates to novel indolyl-oxadiazolyl-diazabicyclononane derivatives and their use in the manufacture of pharmaceutical compositions. The compounds of the invention are found to be cholinergic ligands at the nicotinic acetylcholine receptors and modulators of the monoamine receptors and transporters. Due to their pharmacological profile the compounds of the invention may be useful for the treatment of diseases or disorders as diverse as those related to the cholinergic system of the central nervous system (CNS), the peripheral nervous system (PNS), diseases or disorders related to smooth muscle contraction, endocrine diseases or disorders, diseases or disorders related to neuro-degeneration, diseases or disorders related to inflammation, pain, and withdrawal symptoms caused by the termination of abuse of chemical substances.

[18F]NS14490, a new potential radiotracer for neuroimaging of α7 nicotinic acetylcholinereceptors (α7 nAChRs), was synthesized and evaluated in vitro and in vivo. Radioligand binding studies using [3H]methyllycaconitine and NS14490 as competitor showed a good target affinity (Ki,α7 = 2.5 nM) and a high selectivity towards other nAChRs. Radiosynthesis of [18F]NS14490 was performed by two different
[ 18 F ] NS14490是一种新的潜在的放射性示踪剂,可对α7烟碱乙酰胆碱受体(α7nAChRs)进行神经成像,并在体内和体外进行评估。使用[ 3 H]甲基甘可卡因和NS14490作为竞争剂的放射性配体结合研究显示了良好的靶标亲和力(K i,α7 = 2.5 nM)和对其他nAChRs的高选择性。[ 18 F ] NS14490的放射合成通过两种不同的标记程序进行:使用修复基团的两步合成,可导致7%的标记收率;以及相应甲苯磺酸酯前体的便捷直接亲核取代,可导致70%的标记收率。优化分离,纯化和配制工艺后,在CD-1小鼠中进行了生物分布研究。[ 18 F ] NS14490的大脑摄取相对较低(在pi 5分钟时的湿重为0.16%ID g -1)。放射性示踪剂在血浆和脑中显示出很高的代谢稳定性。同样,通过预先给予高亲和力α7配体证明了靶标特异性,为进一步的体内评估提供了理论依据。
