In vitro cholinesterase inhibition potential of compounds (1a–1f).

Compound	AChEI (IC50 (nM))	BuChEI (IC50 (nM))
1a	2615.42	5347.16
1b	733.84	2159.08
1c	467.18	1356.14
1d	112.52	378.43
1e	3267.95	6635.82
1f	5839.96	9664.71
Donepezil	9.31	33.65

Donepezil was used as positive control. Data were expressed in mean ± SEM, (n = 3), and significantly different values were compared to positive control.
