A series of 2-acetyl-5-O-(amino-alkyl)phenol derivatives was designed, synthesized and evaluated as multi-function inhibitors for the treatment of Alzheimer’s disease (AD). The results revealed that compound TM-3 indicated selective AChE inhibitory potency (eeAChE, IC50 = 0.69 μM, selective index (SI) = 32.7). Both kinetic analysis of AChE inhibition and molecular modeling study suggested that TM-3
synthesized and evaluated as multifunctional anti-Alzheimer's diseaseagents. Based on the experimental results, compound 23c exhibited good inhibitory potency on both acetylcholinesterase (IC50 = 1.3 ± 0.01 μM) and butyrylcholinesterase (IC50 = 1.2 ± 0.09 μM). Besides, 23c exhibited selective MAO-B inhibitory activity with IC50 value of 0.57 ± 0.01 μM. Compound 23c was also a potential antioxidant and neuroprotectant
