Summary

Carfilzomib is a synthetic tetrapeptide epoxyketone that selectively and irreversibly inhibits the 20S proteasome, approved for relapsed or refractory multiple myeloma.

Mechanism of Action

Irreversible covalent inhibition of the 20S proteasome chymotrypsin-like activity by binding to the N‑terminal threonine of the β5 subunit

Routes of Administration

Intravenous
