| 摘要: | In this study, we report three novel naturally occurring compounds, blapsins A (1) and B (2), and blapsamide (3) from the ethanol extract of the stink beetle, Blaps japanensis. The structures of these compounds were determined using spectroscopic methods. Compound 3 is a phenolic compound bearing a formamido group in the structure. Functional studies revealed that compounds 1 and 2 potently inhibited 14-3-3 protein-protein interactions (PPIs) with IC50 values of 9.2 and 10.0 mu M as determined by an ELISA assay, and 2.0 and 2.5 mu M in an FP assay, respectively. These compounds represent the first example of natural small-molecule 14-3-3 inhibitors. (C) 2012 Elsevier Ltd. All rights reserved. |
