The methyl group in cis stereochemical relationship with the basic chain of all pentatomic cyclic analogues of ACh is crucial for the agonist activity at mAChR. Among these only cevimeline (1) is employed in the treatment of xerostomia associated with Sjögren’s syndrome. Here we demonstrated that, unlike 1,3-dioxolane derivatives, in the 1,4-dioxane series the methyl group is not essential for the
与ACh的所有五原子环状类似物的主链成顺式立体化学关系的甲基对于在mAChR处的激动剂活性至关重要。在这些中,只有Cevimeline(1)用于治疗与干燥综合征相关的口干症。在这里,我们证明了与1,3-二氧戊环衍生物不同,在1,4-二氧六环系列中,甲基对于激活mAChR亚型不是必需的。使用人M 2和大鼠M 3受体的晶体结构的对接研究表明,化合物10的1,4-二恶烷核的5-亚甲基与1,3-的甲基具有相同的亲脂性口袋二氧戊环4。
