due to hyperactivation of cholinesterases (acetylcholinesterase (AChE) and butyrylcholinesterase (BChE)). OBJECTIVE Therefore, inactivation of AChE and BChE by inhibitors can increase the acetylcholine level and hence may be an encouraging strategy for the treatment of AD and related neurological problems. METHOD In this contribution, two series of chromenone-based derivatives were tested by Ellmann's
背景技术阿尔茨海默氏病(AD)是老龄化人群中痴呆的主要原因。这种破坏性疾病通常与逐渐记忆力减退有关,这是由于胆碱酯酶(乙酰胆碱酯酶(AChE)和丁酰胆碱酯酶(BChE))的过度活化导致大脑皮质海马区乙酰胆碱水平降低所致。目的因此,抑制剂使AChE和BChE失活可以增加乙酰胆碱水平,因此可能是治疗AD和相关神经系统疾病的令人鼓舞的策略。方法在此贡献中,通过Ellmann量热法测试了两套基于色酮的衍生物对AChE和BChE的抑制作用。结果所有化合物均显示出对胆碱酯酶的抑制活性,其中一些对AChE和BChE均具有双重抑制作用。AChE最有效的抑制剂是2l,IC50值为0.08±0.03 µM,而3q抑制BChE,IC50值为0.04±0.01 µM。在双重抑制的情况下,3h对AChE的抑制浓度为0.15±0.01 µM,对BChE的抑制浓度为0.09±0.01 µM。进行了分子对接研究以探索最有
