AbstractAccumulating evidence suggested that soluble oligomeric beta-amyloid protein (A beta) exerts diverse roles in neuronal cell death, neuroinflammation, oxidative stress, and the eventual dementia associated with Alzheimer's disease (AD). Developing an agent with multiple properties may be a reasonable strategy for the treatment of AD. In this study, we isolated a novel multifunctional compound named camellikaempferoside B (YCF-2) from Fuzhuan brick tea. YCF-2 consists of kaempferol backbone, p-coumaric acid (p-CA) group, and a novel structure of rhamnopyranosyl group at the C-4' position, possessing the properties of both kaempferol and p-CA. YCF-2 significantly inhibited A beta production by decreasing beta-secretase activity. Moreover, YCF-2 suppressed A beta 42 fibrillation and facilitated nontoxic oligomer formation by binding to A beta 42 oligomers and by blocking the conformational transition to beta-sheet. Furthermore, YCF-2 ameliorated A beta-induced neuronal cell death, ROS production, inflammatory factor release, and microglia activation by blocking the NF-kappa B signaling pathway in microglia. These findings indicated that YCF-2 with a novel lead structure has potential applications for drug development for AD treatment.
