The present study reports the synthesis of cinnamide derivatives and their biological activity as inhibitors of both cholinesterases and anticancer agents. Controlled inhibition of brain acetylcholinesterase (AChE) and butyrylcholinesterase (BChE) may slow neurodegeneration in Alzheimer's diseases (AD). The anticholinesterase activity of phenylcinnamide derivatives was determined against Electric Eel
本研究报告了肉桂酰胺衍生物的合成及其作为胆碱酯酶和抗癌剂抑制剂的生物活性。对大脑乙酰胆碱酯酶(AChE)和丁酰胆碱酯酶(BChE)的受控抑制可能会减缓阿尔茨海默氏病(AD)中的神经变性。确定了苯基肉桂酰胺衍生物对Eel乙酰胆碱酯酶(EeAChE)和马血清丁酰胆碱酯酶(hBChE)的抗胆碱酯酶活性,某些化合物似乎是EeAChE和hBChE的中等有效抑制剂。化合物3-(2-(苄氧基)苯基)-N-(3,4,5-三甲氧基苯基)丙烯酰胺(3i)具有IC 50的最大抗EeAChE活性0.29±0.21μM,而3-(2-氯-6-硝基苯基)-N-(3,4,5-三甲氧基苯基)丙烯酰胺(3k)被证明是hBChE最有效的抑制剂,IC 50为1.18± 1.31μM 。为了更好地了解最具活性的化合物对胆碱酯酶的酶-抑制剂相互作用,对高分辨率晶体学结构进行了分子建模研究。还评估了合成化合物对癌细胞系(肺癌)的抗癌作
