Biochem/physiol Actions
Proteasomes are responsible for the cleavage of peptides in an ATP/ubiquitin-dependent manner.
VR23 is a potent inhibitor of proteasome that primary targets β2 of the 20S proteasome catalytic subunit. VR23 selectively induces apoptosis to cancer cells via cyclin E–mediated centrosome amplification. VR23 exhibit little effect on noncancerous cells.

The proteasome is clinically validated as a target for cancer therapeutics. However, proteasome-inhibitory agents that are cancer selective have yet to be developed. In this study, we report the identification of a safe and effective proteasome inhibitor with selective anticancer

To date individual markers have failed to correctly predict resistance against anticancer agents in breast cancer. We used gene expression patterns attributable to chemotherapy-resistant cells to detect potential new biomarkers related to anthracycline resistance. One of the genes, PSMB7, was
