Fig. 5. Viability of the SH-SY5Y cells with Aβ1–42 in the presence and absence of designated concentrations of donepezil and compounds (15, 26, and 27) after 48 h, as determined using the MTS assay. The control group was observed as 100% cell viability, and the assays were performed in triplicate. *P < 0.05, **P < 0.01, ***P < 0.001 and ns = non-significant.
