β5i-IN-2
β5i-IN-2 is a potent, selective, and orally active inhibitor of the immunoproteasome β5i subunit, with an IC50 of 0.08 μM against human β5i. β5i-IN-2 inhibits LPS (HY-D1056)- and IFN-γ-induced expression of IL-1β, IL-6, and TNF-α, and suppresses the JNK, ERK, and NF-κB signaling pathways. β5i-IN-2 can be used in research related to rheumatoid arthritis and ulcerative colitis.

β5i 0.08 μM (IC50) |
β5i-IN-2 (compound ent-F10) (1 μM; serial dilutions; 10-15 min) potently and selectively inhibits the immunoproteasome β5i in cell-free lysate and purified proteasome assays, with an IC50 of 0.08 μM, and a selectivity index of 123.8 over the constitutive proteasome β5[1].
β5i-IN-2 exhibits low affinity for hERG ion channels in HEK293 cells, indicating a low risk of cardiotoxicity[1].
β5i-IN-2 (10-40 nM; pre-treatment for 1 h) reduces the mRNA expression of IL-1β, IL-6 and TNF-α in RAW 264.7 cells in a concentration-dependent manner after stimulation with LPS (100 ng/mL) and IFN-γ (20 ng/mL) for 24 h[1].
β5i-IN-2 (10-40 nM; 4 h pre-treatment) reduces JNK and ERK phosphorylation in RAW 264.7 cells in a concentration-dependent manner following 15 min of stimulation with LPS and IFN-γ, and restores IκBα protein levels[1].
