  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.

  A series of oxadiazole derivatives were synthesized and evaluated as 5-hydroxytryptamine-4 receptor (5-HT4R) partial agonists for the treatment of cognitive deficits associated with Alzheimer’s disease. Starting from a reported 5-HT4R antagonist, a systematic structure–activity relationship was conducted, which led to the discovery of potent and selective 5-HT4R partial agonist 1-isopropyl-3-5-[1-(3-methoxypropyl)

  合成并评估了一系列恶二唑衍生物作为 5-羟色胺-4 受体 (5-HT 4 R) 部分激动剂，用于治疗与阿尔茨海默病相关的认知缺陷。从报道的 5-HT 4 R 拮抗剂开始，进行了系统的构效关系，从而发现了有效和选择性的 5-HT 4 R 部分激动剂 1-异丙基-3-5-[1-(3 -甲氧基丙基）哌啶-4-基]-[1,3,4]恶二唑-2-基}-1H-吲唑草酸盐（Usmarapride，12l）。它在认知模型中表现出平衡的理化-药代动力学特性，具有强大的非临床功效。它还显示出改善疾病的潜力，因为它增加了神经保护性可溶性淀粉样前体蛋白 α 水平，以及剂量依赖性靶标参与和功效与口服暴露的相关性。1 期临床研究已完成，预计有效浓度已达到，没有任何重大安全问题。实现长期安全性研究的第 2 阶段已经完成，无需担心进一步开发。
