  α7nAChR激动剂SEN12333类似物中酰胺键变化和联芳基修饰的研究

  摘要：

  实验几条证据支持α参与7胆碱受体在精神分裂症和老年痴呆症。α7nAChR的调节剂已被广泛审查与这些病理相关的认知功能障碍的治疗。SEN12333代表一种新型的α7nAChR激动剂化学型，具有减少副作用的潜力，但需要进一步的SAR探索。本工作研究了SEN12333的酰胺键，特别是其连接性和被四唑官能团（一种已知的顺式）取代酰胺等排。结果表明，SEN12333的原始酰胺键连接性有利于在α7nAChRs上的结合亲和力和激动剂活性。使用四唑等排物完全消除了亲和力和功能活性，并表明SEN12333以线性构象结合。本文报道的结果还表明SEN12333的末端芳族环内的吡啶氮对于结合亲和力或功能活性不是必需的。有必要对涉及操纵SEN12333中包含的其他部分的SAR进行进一步的调查。

  Alpha 7 nicotinic acetylcholine receptor (alpha(7) nAChR) agonists are promising therapeutic candidates for the treatment of cognitive impairment associated with a variety of disorders including Alzheimer's disease and schizophrenia. Alpha 7 nAChRs are expressed in brain regions associated with cognitive function, regulate cholinergic neurotransmission and have been shown to be down regulated in both schizophrenia and Alzheimer's disease. Herein we report a novel, potent small molecule agonist of the alpha 7 nAChR, SEN12333/WAY-317538. This compound is a selective agonist of the alpha(7) nAChR with excellent in vitro and in vivo profiles, excellent brain penetration and oral bioavailability, and demonstrates in vivo efficacy in multiple behavioural cognition models. The SAR and biological evaluation of this series of compounds are discussed. (C) 2009 Elsevier Ltd. All rights reserved.

  Alpha-7 nicotinic acetylcholine receptor (alpha 7 nAChR) agonists are promising therapeutic candidates for the treatment of cognitive impairment. We report a series of novel, potent small molecule agonists (4-18) of the alpha 7 nACh R deriving from our continuing efforts in the areas of Alzheimer's disease and schizophrenia. One of the compounds of the series containing a urea moiety (16) was further shown to be a selective agonist of the alpha 7 nAChR with excellent in vitro and in vivo profiles, brain penetration, and oral bioavailability and demonstrated in vivo efficacy in multiple behavioral cognition models. Structural modifications leading to the improved selectivity profile and the biological evaluation of this series of compounds are discussed.

  A series of ligands based on SEN12333, containing either contracted or elongated alkyl chains, were synthesized and evaluated in molecular docking studies against a homology model of the alpha 7 nicotinic acetylcholine receptor (nAChR) subtype. The predicted binding of all ligands was highly similar, with the exception of the analog containing a 5 methylene unit spacer. However, in vitro competition binding assays revealed that the ligands possessed dissimilar binding affinities, with a K-i range of more than an order of magnitude (K-i = 0.50 to >10 mu M), and only SEN12333 itself exhibited functional activity at the alpha 7 nAChR.
