Abstract

Various plant phenolics were assessed for (${\beta}$-secretase (BACE1) inhibitory activity in order to screen for anti-dementia agents. Among 39 phenolics, eight compounds, 1,2,3-trigalloyl glucopyranoside, acetonyl geraniin, euphorscopin, furosine, helioscopinin A, helioscopinin B, jolkinin, and rugosin E exhibited strong inhibition of BACE1 with $IC_{50}$ values of $5.87{\times}10^{-8}-54.93{\times}10^{-6}\;M$. Among them, rugosin E was the most potent ($IC_{50}$ $5.87{\times}10^{-8}\;M$). The active compounds were shown to be non-competitive inhibitors by Dixon plot. All the phenolic BACE1 inhibitors except furosin also suppressed prolyl endopeptidase (PEP) activity. However, these phenolic compounds caused less inhibition of ${\alpha}$-secretase (tumor necrosis factor a converting enzyme; TACE) and no significant inhibition of other serine proteases such as trypsin, chymotrypsin, and elastase was seen, demonstrating that they are relatively specific to both BACE1 and PEP. No significant structure-activity relationships were found.
