Spontaneous aggregation of A beta is a key factor in the development of Alzheimer's disease. In searching for A beta aggregation inhibitors from traditional Chinese herbal medicines, we identified two active compounds from Psoraleae Fructus, namely isobavachalcone and bavachinin. We further demonstrated that the two compounds modulate A beta 42 aggregation process through different mechanisms. Isobavachalcone significantly inhibits both oligomerization and fibrillization of A beta 42, whereas bavachinin inhibits fibrillization and leads to off-pathway aggregation. Both of the compounds attenuated A beta 42-induced toxicity in a SH-SY5Y cell model. These findings may provide valuable information for new drug development and Alzheimer's therapy in the future.
