Description

PSI (Proteasome Inhibitor 1) is a potent proteasome inhibitor. PSI inhibits the proliferation of primary effusion lymphoma (PEL) cells. PSI has the potential for the research of Kaposi’s sarcoma-associated herpesvirus (KSHV) infection and KSHV-associated lymphomas[1].

In Vitro

PSI (24 h) inhibits the proliferation of primary effusion lymphoma (PEL) cells at low nanomolar concentrations (CC50s of 205, 190, 22.0, 53.0 nM FOR BJAB, Ramos, BC3, BCBL1 cells, respectively)[1].
PSI (50 nM; 6 h) increases caspase-3/7 activity by 8-fold compared with control[1].
PSI (50 nM; 6 h) decreases the transcriptional activity of NF-κB by 52%[1].
PSI (1, 5 nM; 3 days) inhibits the growth of BC3 cells at a high concentration (5 nM)[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
