The synthesis of racemic tetrahydrocurcumin- (THC-), tetrahydrodemethoxycurcumin- (THDC-) and tetrahydrobisdemethoxycurcumin- (THBDC-) dihydropyrimidinone (DHPM) analogues was achieved by utilizing the multi-component Biginelli reaction in the presence of copper sulphate as a catalyst. The evaluation of acetylcholinesterase inhibitors for Alzheimer’s disease of these compounds showed that they exhibited
外消旋四氢姜黄素-(THC-),四氢去甲氧基姜黄素-(THDC-)和四氢双去甲氧基姜黄素-(THBDC-)二氢嘧啶酮(DHPM)类似物的合成是通过在硫酸铜作为催化剂的情况下利用多组分Biginelli反应来实现的。对这些化合物的阿尔茨海默氏病的乙酰胆碱酯酶抑制剂的评估表明,它们显示出比其母体类似物更高的抑制活性。THBDC-DHPM表现出最强的抑制活性,IC 50值为1.34± 0.03μM ,比经批准的加兰他敏药(IC 50 = 1.45±0.04μM)更具活性。
