Potent inhibitor of proteasome that primary targets β2 of the 20S proteasome catalytic subunit
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.
