(1S,2S)-Bortezomib - HY-135396

(1S,2S)-Bortezomib is an enantiomer of Bortezomib. Bortezomib is a cell-permeable, reversible, and selective proteasome inhibitor, and potently inhibits 20S proteasome (Ki of 0.6 nM) by targeting a threonine residue. Bortezomib disrupts the cell cycle, induces apoptosis, and inhibits NF-κB. Bortezomib is an anti-cancer agent and the first therapeutic proteasome inhibitor to be used in humans[1][2][3].
