Introduction of 158442-41-2 :

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].
