Carfilzomib

PR-171, Kyprolis, CFZ

Selective proteasome inhibitor approved (Kyprolis) for multiple myeloma, typically after prior therapies. Blocks protein breakdown in cancer cells, causing toxic protein buildup and cell death.

Mechanism

Irreversibly binds the β5 subunit of the 20S proteasome/immunoproteasome’s catalytic threonine, blocking chymotrypsin-like activity; this piles up ubiquitinated proteins, triggering ER stress, cell-cycle arrest, and apoptosis, especially in high-protein-turnover myeloma cells.

Safety file

Carries serious cardiovascular risks (heart failure, ischemia), kidney toxicity, and blood-cell toxicity (low platelets); needs close monitoring.
