Zetomipzomib (maleate)

Zetomipzomib (KZR-616) maleate, a first-in-class immunoproteasome inhibitor, selectively targets the LMP7 (IC50: 39/57 nM=hLMP7/mLMP7) and LMP2 (IC50: 131/179 nM=hLMP2/mLMP2) subunits of the immunoproteasome. Zetomipzomib maleate has the potential for the research of multiple autoimmune diseases[1][2].
