  Design of [R-(Z)]-(+)-α-(Methoxyimino)-1-azabicyclo[2.2.2]octane-3-acetonitrile (SB 202026), a Functionally Selective Azabicyclic Muscarinic M1 Agonist Incorporating the N-Methoxy Imidoyl Nitrile Group as a Novel Ester Bioisostere

  摘要：

  Loss of cholinergic function is believed to be implicated in the cognitive decline associated with senile dementia of the Alzheimer type (SDAT). The disease is characterized by progressive loss of muscarinic receptors located on nerve terminals while postsynaptic muscarinic M1 receptors appear to remain largely intact. Muscarinic agonists acting directly on postsynaptic receptors offer the prospect of countering the cholinergic deficit in SDAT. This study describes a novel series of azabicyclic muscarinic agonists, which incorporate an oxime ether or modified oxime ether group as an ester bioisostere. Modification of the oxime ether function by the introduction of electron withdrawing groups led to the finding that the (Z)-N-methoxy imidoyl nitrile group serves as a stable methyl ester bioisostere. This culminated in the discovery of the quinuclidinyl N-methoxy imidoyl nitrile R-(+)-(Z)-5g which is a functionally selective muscarinic M1 partial agonist currently in phase III clinical trials for the treatment of SDAT. The selective profile of R-(+)-(Z)-5g can be rationalized in terms of the relative affinity of the compound at muscarinic receptor subtypes, the degree of agonist efficacy, and brain penetrancy.

  比较氮杂双环酯和恶二唑作为毒蕈碱受体的配体。

  摘要：

  与阿尔茨海默氏型痴呆症相关的认知缺陷与疾病中胆碱能功能的丧失之间的联系为检查毒蕈碱激动剂作为潜在治疗剂提供了基础。本文描述了新型的氮杂双环甲酯作为毒蕈碱受体配体的设计和合成。用3-甲基-1,2,4-恶二唑环取代甲酯可产生有效的代谢更稳定的毒蕈碱激动剂，能够穿透中枢神经系统。这些化合物相对于相应的甲酯通常显示出改善的亲和力。3-甲基1,2,4-恶二唑7b的亲和力是乙酰胆碱的4倍。关于氮杂双环的大小和几何形状以及杂芳族环的电子性质，讨论了受体亲和力。

  The effect of variation of the 1-azabicyclic substituent on the novel 1,2,3-triazol-4-yl-, 1,2,4-triazol-1-yl-, tetrazol-5-yl-, and tetrazol-2-yl-based muscarinic receptor ligands ha, been studied, and the exo-azabicyclic[2.2.1]hept-3-yl substituent was found to give the most potent and efficacious compounds. In addition, variation of the second substituent on 1,2,4-triazol-1-yl- and tetrazol-2-yl-based muscarinic receptor ligands has yielded a series of novel compounds with high potencies and efficacies, ranging from full agonists to antagonists. Small lipophilic electron withdrawing substituents give potent but low efficacy compounds, while small polar electron donating substituents give potent and efficacious compounds. The activity of these compounds is described in terms of a model of the receptor involving lipophilic and hydrogen bonding interactions. These compounds provide muscarinic ligands with high potency and a range of efficacies suitable for testing as candidate drugs in the treatment of Alzheimer's disease.
