The measurement of biotinyl-Aβ_(1–42) (bioAβ₄₂) oligomer assembly inhibition of compounds 3, 17, donepezil, 20, ethylene glycol, 3 + ethylene glycol, and 15a (A) and compounds 3 + donepezil, 3 + 20, 17 + donepezil, 17 + 20, donepezil + ethylene glycol, and 3 + donepezil + ethylene glycol (B). Tween 20 (assembly inhibition) and 2,5-DHBA (2,5-dihydroxybenzoic acid) (dissociator) were used as controls. These experiments were performed in duplicate (n = 1 independent experiment). The error bars represent standard deviations (SDEV).
