초록
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.
