Two novel naphthol derivatives (1 and 2) were synthesized and characterized via IR, 1H NMR, and HRMS. The structure of compound 2 was verified by single-crystal X-ray crystallography. It crystallizes in monoclinic, space group C2/c with a = 21.6725(9), b = 6.0127(3), c = 25.5405(14) Å, β = 94.716(5)°, V = 3316.9(3) Å3, Z = 8, F(000) = 1384, Dc = 1.511 Mg/m3, Mr = 377.22 and μ = 2.487 mm-1. In addition, their cholinesterase inhibitory activities in vitro toward Electrophorus electricus acetylcholinesterase (eelAChE) and horse serum butyrylcholinesterase (eqBChE) were further determined. The results showed that compound 1 as a new acetylcholinesterase (AChE) inhibitor displayed higher AChE inhibitory activity (IC50 = 1.4 μM), which could be considered for Alzheimer’s disease therapeutics.
