  发现N-磺酰基-7-氮杂二氢吲哚衍生物作为有效的，口服可利用的和选择性的M 4毒蕈碱型乙酰胆碱受体激动剂

  摘要：

  我们设计和合成了新型的N-磺酰基-7-氮杂二氢吲哚衍生物，作为选择性的M 4毒蕈碱乙酰胆碱受体激动剂。化合物2（一种M 4毒蕈碱乙酰胆碱受体（mAChR）偏爱的激动剂）的N-甲乙氧基哌啶部分的修饰导致了化合物1（一种选择性的M 4 mAChR激动剂）。化合物1显示出高度选择性的M 4 mAChR激动活性，体外hERG抑制作用较弱。体内化合物1的药代动力学研究表明，大鼠具有良好的生物利用度和脑渗透性。化合物1 逆转了甲基苯丙胺诱导的大鼠运动过度活跃（1-10 mg / kg，口服）。

  Discovery of NovelN-Substituted Oxindoles as Selective M₁and M₄Muscarinic Acetylcholine Receptors Partial Agonists

  摘要：

  Activation of the M-1 and M-4 muscarinic acetylcholine receptors is thought to play an important role in improving the symptoms of schizophrenia. However, discovery of selective agonists for these receptors has been a challenge, considering the high sequence homology and conservation of the orthosteric acetylcholine binding site among muscarinic acetylcholine receptor subtypes. We report in this study the discovery of novel N-substituted oxindoles as potent muscarinic acetylcholine receptor partial agonists selective for M-1 and M-4 over M-2, M-3, and M-5. Among these oxindoles, compound 1 showed high selectivity for the M-1 and M-4 receptors with remarkable penetration into the central nervous system. Compound 1 reversed methamphetamine- and apomorphine-induced psychosis-like behaviors with low potency to extrapyramidical and peripheral side effects.

  We designed and synthesized a series of dihydroquinazolinone derivatives as selective M-1 and M-4 muscarinic acetylcholine receptors agonists. Introduction of the N-carbethoxy piperidine unit into a HTS hit compound followed by optimization of the amine linker and the carbamoyl moiety led to the identification of compound 1 as a potential candidate. The identified compound 1 showed high selectivity for M-1 and M-4 muscarinic acetylcholine receptors with M-4 partial agonistic activity. In addition, compound 1 showed good brain penetration and reversed methamphetamine-induced hyperlocomotion in rats (ED50 = 3.0 mg/kg, sc). (C) 2015 Elsevier Ltd. All rights reserved.
