C25-140, a first-in-class, orally active, and fairly selective TRAF6-Ubc13 inhibitor, directly binds to TRAF6, and blocks the interaction of TRAF6 with Ubc13. C25-140 lowers TRAF6 activity, reduces NF-κB activation, and combats autoimmunity.

TRAF6-Ubc13
体外研究
C25-140 dose-dependently impedes TRAF6-Ubc13 interaction.
C25-140 (10-30 μM; 2 hours) effectively reduces TRAF6-mediated ubiquitin chain formation.
C25-140 affects TNFα-induced phosphorylation of IκBα as well as NF-κB-induced target gene expression.
C25-140 efficiently inhibits IL-1β- and TNFα-mediated receptor signaling in the context of cytokine activation.
C25-140 (~1.5 mg/kg; topically to the shaved back and the right ear; twice daily for 6 days) ameliorates symptoms of autoimmune psoriasis in R 837-induced psoriasis mouse model.
C25-140 (6-14 mg/kg; given i.p.; twice daily for 14 days) shows a dose-dependent improvement of RA disease outcome in Collagen-induced arthritis (CIA) model.
C25-140 (10 mg/kg; i.v.) treatment shows that the Cmax, AUC, t1/2 and Vd are 9.7 μg/mL, 274083 ng min/mL, 80.62 min, and 4.13 L/kg, respectively. .
C25-140 (10 mg/kg; p.o.) treatment shows that the Cmax, AUC, t1/2 and Vd are 3.4 μg/mL, 124034 ng min/mL, 127.33 min and 13.3 L/kg, respectively.
