Prevention of aggregation and oxidation by test compounds in biochemical assays. A, Aβ aggregation inhibition of Lico A, coumarin, LM‐004, LM‐006, LM‐026, LM‐016, LM‐031, and curcumin (5‐20 μmol/L) (n = 3). To normalize, the relative thioflavin T fluorescence of Aβ₄₂ without compound addition was set at 100%. Shown below are the EC₅₀ values. B, DPPH radical scavenging activity of kaempferol, Lico A, coumarin, LM‐004, LM‐006, LM‐026, LM‐016, LM‐031, and curcumin (10‐160 μmol/L) (n = 3). Shown below are the EC₅₀ values
