Additional Information:

Carfilzomib is a potent and irreversible proteasome inhibitor (1) being a synthetic analog of the microbial product epoxomcin (2). This compound compared to bortezomib displays equal potency but greater selectivity for the chymotrypsin-like activity of the proteasome and in cell culture it is more cytotoxic than bortezomib and hematologic tumor cells exhibit greater sensitivity than solid tumor cells. The treatment of cells with carfilzomib results in the accumulation of proteasome substrates and induction of cell cycle arrest and/or apoptosis (3), is effective against multiple myeloma (4) and is active in vivo.
