產(chǎn)品描述：

PSI is a synthetic peptide proteasome inhibitor.1,2,3 It inhibits the acidic and neutral chymotrypsin-like activities of the 20S proteasome (IC50s = 0.25 and 6.5 μM, respectively).3 PSI is cytotoxic to HL-60, KG-1a, RWLeu-4, AR230, and K562 human leukemia cells (IC50s = 4.9, 17.5, 7.8, 7.3, and 10 nM, respectively).4 It selectively induces apoptosis in subconfluent bovine aortic endothelial cells (BAECs) and human umbilical vein endothelial cells (HUVECs; EC50s = 24 and 7 nM, respectively) over confluent BAECs and HUVECs (EC50s = 8,150 and 7,830 nM, respectively).5 PSI induces accumulation of ubiquitin-protein conjugates in HT4 mouse neuronal cells.6
