    Novel 5-HT3 antagonists. Indole oxadiazoles
    摘要:
    The synthesis and biochemical evaluation of a series of indole oxadiazole 5-HT3 antagonists are described. The key pharmacophoric elements have been defined as a basic nitrogen, a linking group capable of H-bonding interactions, and an aromatic moiety. The steric limitations of the aromatic binding site have been determined by substitution about the indole ring. Variation of the heterocyclic linking group has shown that while two hydrogen-bonding interactions are possible, only one is essential for high affinity. The environment of the basic nitrogen has been investigated and shown to be optimal when constrained within an azabicyclic system. These results have been incorporated into a proposed binding model for the 5-HT3 antagonist binding site, in which the optimum distance between the aromatic binding site and the basic amine is 8.4-8.9 angstrom and the steric limitations are defined by van der Waals difference mapping.

    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。

    been discovered that an oxadiazole ring and related heterocycles can function as bioisosteric replacements for the ester moiety found in several known muscarinic ligands. Within this series there exist compounds which span the efficacy range from high-efficacy agonist through partial agonists to antagonists with affinity comparable or superior to that of classical quaternary ammonium ligands.

    最近对阿尔茨海默氏病患者的临床研究表明,只有对毒蕈碱样皮质受体表现出高功效的药物才能产生令人鼓舞的结果。本文介绍了新型奎宁环胺基毒蕈碱激动剂的设计,合成和生化特性,这些激动剂可以轻松渗透到中枢神经系统中,并且能够在皮质部位发挥高效作用。通过使用能够测量受体亲和力并预测皮质功效的生化测定法,已发现恶二唑环和相关的杂环可以作为在几种已知毒蕈碱配体中发现的酯部分的生物立体替代物。在这一系列化合物中,存在的化合物的功效范围从高效激动剂到部分激动剂,再到具有与传统季铵配体相当或更高亲和力的拮抗剂。与最近的分子生物学研究一致,结构活性趋势是根据激动剂和拮抗剂的独立结合位点来解释的,其中H-键相互作用表征激动剂行为,而亲脂性结合表征拮抗剂行为。因此,氨基恶二唑部分具有针对激动剂分布进行优化的结构特征。根据激动剂和拮抗剂的单独结合位点来解释结构活性趋势,其中H-键相互作用表征激动剂行为,而亲脂性结合表征拮
