As an extension of our previous work on donepezil-based “bio-oxidizable” prodrug approach, two new classes of N-benzylpyridinium donepezil analogues in tetralone B2 and acetophenone B3 series and a new set of indanone derivatives B1 were investigated along with the corresponding dihydropyridine prodrugs A1-3. A total of fifty one N-benzylpyridinium quaternary donepezil analogues B1-3 and twenty two
作为我们先前基于多奈哌齐的“生物可氧化”前药方法工作的扩展,研究了四氢萘酮B2和苯乙酮B3系列中的两类新的N-苄基吡啶多奈哌齐类似物以及一组新的茚满酮衍生物B1以及相应的二氢吡啶前药A1-3。总共合成了五十一个N-苄基吡啶季铵盐多奈哌齐类似物B1-3和二十二个前药A1-3,并评估了它们对h AChE和eq BuChE的抑制活性。而大多数前药A1-3被证明对AChE无活性(IC 50 > 10μM),大量相应的N-苄基吡啶鎓盐B1-3表现出有吸引力的三到一位数纳摩尔h AChE抑制活性,甚至达到亚纳摩尔活性(IC 50 = 0.36 nM)。此外,对几种化合物进行了计算机对接研究,以解释更相关的体外结果。最后,还评估了前药A中两个立体生成中心的影响,不仅突出了前药23h的四个分离异构体在残留AChE抑制活性方面的显着差异(IC50范围从173 nM到10μM),但前药24a的两个分离的非
