商品描述
ONX-0914 is an immunoproteasome inhibitor with potential treatment applications in autoimmune disorders, such as rheumatoid arthritis, inflammatory bowel disease and lupus. ONX-0914 was designed to be a potent inhibitor of the immunoproteasome with minimal cross-reactivity for the constitutive proteasome.

In vitro(体外研究)
ONX-0914 is 20- to 40-fold more selective for LMP7 over the next most sensitive sites, β5 or LMP2. ONX-0914 blocks presentation of LMP7-specific, MHC-I–restricted antigens in vitro and in vivo with minimal cross-reactivity for the constitutive proteasome. Selective inhibition of LMP7 by ONX-0914 blocks production of interleukin-23 (IL-23) by activated monocytes and interferon-gamma and IL-2 by T cells. LMP7 inhibition blocks production of IL-23 by ~90% and of tumor necrosis factor-α (TNF-α) and IL-6 by ~50%.
In vivo(体内研究)
In mouse models of rheumatoid arthritis and lupus, ONX-0914 treatment reverses signs of disease and results in reductions in cellular infiltration, cytokine production and autoantibody levels at well-tolerated doses. The maximum tolerated dose (MTD) of ONX-0914 in mice to be 30 mg/kg body weight. IFN-g release is inhibited by ~60% at LMP7-selective concentrations of ONX-0914 and by ~90% at higher concentrations. Production of IL-2 is also inhibited by ~50%.
