Bortezomib | Proteasome inhibitor

Potent and selective proteasome inhibitor (Ki=0.6 nM). Inhibits proliferation of a number of tumor cell lines (IC50=7 nM).  Inhibits TNFα synthesis and FGF-induced angiogenesis. Clinically useful agent for treatment of multiple myeloma.3 Shows promise in the treatment of neurodegenerative diseases in which low-expressing proteins such as IKAP/hELP1 in familial dysautonomia are preserved.4 Reversible. Cell permeable.
