Description: b-AP15 is a novel inhibitor of proteasome deubiquitination. b-AP15 displays antitumor activity in several preclinical, solid tumor models. b-AP15 triggers time- and dose-dependent apoptosis of the human multiple myeloma (MM) cell lines RPMI8226 and U266, as determined by phosphatidylserine exposure. Furthermore, b-AP15 triggered processing of pro-caspase-3 and cleavage of poly (ADP-ribose) polymerase in MM cells. b-AP15 also induced caspase-independent apoptosis in primary human natural killer cells. b-AP15 may have potential for treatment of multiple myeloma patients.
