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

体内研究:
Zetomipzomib (5 mg/kg; i.v.; dosing was repeated on days 6, 8, 11, and 13) shows efficacy in the anticollagen antibody induced arthritis (CAIA) model.Animal Model:7-8 week old female BALB/c mice (CAIA model)
Dosage:I.v.; Dosing was repeated on days 6, 8, 11, and 13 until for 15 day
Administration:5 mg/kg
Result:Showed efficacy in the anticollagen antibody induced arthritis (CAIA) model.

体外研究:
Zetomipzomib also inhibits MECL-1 subunit (IC50=623 nM) and constitutive proteasome β5 subunit (IC50=688 nM). Zetomipzomib maintains LMP7 and LMP2 selective inhibition in MOLT-4 cells. Zetomipzomib (250 nM) shows a comparable cytokine inhibition profile peripheral blood mononuclear cells (PBMC).Zetomipzomib is an immunoproteasome-selective inhibitor identified based on the optimization of ONX-0914 (HY-13207) and PR-924 (HY-123587).
