Design and Synthesis of Novel Derivatives of the Muscarinic Agonist Tetra(ethylene glycol)(3-methoxy-1,2,5-thiadiazol-4-yl) [3-(1-Methyl-1,2,5,6-tetrahydropyrid-3-yl)-1,2,5-thiadiazol-4-yl] Ether (CDD-0304): Effects of Structural Modifications on the Binding and Activity at Muscarinic Receptor Subtypes and Chimeras

As part of a continuing effort to design and synthesize highly selective muscarinic agonists for different muscarinic receptor subtypes, several tetra(ethylene glycol)(3-methoxy-1,2,5-thiadiazol-4-yl) [3-(1-methyl-1,2,5,6-tetrahydropyrid-3-yl)-1,2,5-thiadiazol-4-yl] ether (1) analogues were prepared and characterized. Different analogues were synthesized having hydrophilic spacers of di-, tri-, tetra-
作为设计和合成针对不同毒蕈碱受体亚型的高选择性毒蕈碱激动剂的持续努力的一部分,几种四(乙二醇)(3-甲氧基-1,2,5-噻二唑-4-基)[3-(1-甲基制备并表征了-(1,2,5,6-四氢吡啶-3-基)-1,2,5-噻二唑-4-基]醚(1)类似物。合成了具有二,三,四,五(乙二醇)和三(丙二醇)亲水间隔基的不同类似物,该间隔基将1,2,5,6-四氢吡啶环与末端杂环隔开,后者为1 ,2,5-噻二唑或1,2,4-噻二唑环。还进行了嵌合受体和分子建模研究,以确定配体如何与毒蕈碱受体相互作用。研究表明,改变末端噻二唑的距离和甲氧基的位置可以增加对某些毒蕈碱受体亚型的结合亲和力(对于13d的M(2)和对于1d的M(4))并增强在M( 4)13e和18b的受体。此外,如通过逆转阿扑吗啡诱导的感觉运动门控缺陷所评估的,化合物1显示出抗精神病活性,表明在精神分裂症的治疗中具有潜在的实用性。
