Background:

AM 114, a derivative of boronic chalcone, is a potent small-molecule inhibitor of the proteasome that inhibits the chymotrypsin-like activity of the 20S proteasome, with a value of 50% inhibition concentration IC₅₀of approximately 1 μM, resulting in a significant accumulation of ubiquitinated p53 and other cellular proteins in whole cells without significantly disrupting the interaction of p53 and murine double minute 2 (mdm2) proteins. AM 114 also exerts anti-cancer activity against cancer cells, which potently inhibits the growth of human colon cancer HCT116 cells with values of IC₅₀of 1.5 μM and 0.6 μM in MTT and colony formation assays respectively.
