Compound D737 rescues cells from the cytotoxic effect of Aβ42. The results represent percentage of viable cells compared with untreated cells. a, effect of D737 on the cytotoxicity of Aβ42 oligomers. 20 μm Aβ42 was incubated in the absence (black bars) or presence (gray bars) of 40 μm D737 for the indicated times under oligomerization conditions before being added to PC12 cells. b, D737 showed slight dose-dependent rescue from toxicity caused by Aβ42 oligomers formed during 1 h of incubation. c, D737 showed significant dose-dependent rescue from cytotoxicity caused by Aβ42 oligomers formed after 24 h of incubation. d, effect of D737 on the cytotoxicity of Aβ42 fibrils. 20 μm Aβ42 was incubated under fibrillization conditions in the absence (black bars) or presence (gray bars) of 40 μm D737 for the indicated times before being added to PC12 cells.
