A series of helicid analogues were prepared and evaluated in vitro for the cholinesterase (AChE and BuChE) inhibitory activities via UV spectroscopy. The results indicated that compounds 5, 6d and 8 exhibited potent AChE inhibitory activities with IC(50) values of 0.45+/-0.02microM, 0.49+/-0.02microM, and 0.20+/-0.01microM, respectively. High selectivity for AChE over BuChE was also observed. Kinetic study showed that the mechanism of AChE inhibition of compounds 5, 6d and 8 was all mixed-type.
制备了一系列的螺旋体类似物，并通过紫外光谱法在体外评估了它们对胆碱酯酶（乙酰胆碱酯酶和丁酰胆碱酯酶）的抑制活性。结果表明，化合物5、6d和8表现出较强的乙酰胆碱酯酶抑制活性，IC(50)值分别为0.45±0.02微摩尔、0.49±0.02微摩尔和0.20±0.01微摩尔。还观察到对乙酰胆碱酯酶的选择性高于丁酰胆碱酯酶。动力学研究表明，化合物5、6d和8对乙酰胆碱酯酶的抑制机制均为混合型。
