  • Potent orally bioavailable irreversible proteasome inhibitor. Analog of Carfilzomib (Prod. No. AG-CR1-3669).
  • Targets the chymotrypsin-like β5 subunit of the constitutive 20S proteasome (IC50=36nM) and the β5i subunit [LMP7] of the 20S immunoproteasome (IC50=82nM).
  • Anticancer compound effective in cell-based assays, in xenografts and against multiple myeloma in vivo.
  • In vitro, induces cell cycle arrest and apoptosis in human cancer cell lines including multiple myeloma, as well as in bortezomib resistant multiple myeloma cells.
  • Shown to have anti-angiogenic activity.
  • Has potential applications in certain types of cancer as well as other diseases that require proteasome activity.
