The Carfilzomib, with CAS registry number 868540-17-4, has the systematic name of N-{(2S)-2-[(morpholin-4-ylacetyl)amino]-4-phenylbutanoyl}-L-leucyl-N-{(2S)-4-methyl-1-[(2R)-2-methyloxiran-2-yl]-1-oxopentan-2-yl}-L-phenylalaninamide. It is an analog of epoxomicin. Inhibition of proteasome-mediated proteolysis results in a build-up of polyubiquinated proteins, which may cause cell cycle arrest, apoptosis, and inhibition of tumor growth. Its classification codes are Antineoplastic Agents and Treatment of cancer. And the chemical formula of this chemical is C₄₀H₅₇N₅O₇.
