KBD4466
KBD4466 is an orally active potent TLR7 and TLR8 inhibitor with IC50s of 0.9 nM and 2.8 nM, respectively. KBD4466 inhibits the expression of inflammatory cytokines IL-6 and IFN-α. KBD4466 improves disease progression and survival in the BXSB/MpJ mouse model of Systemic Lupus Erythematosus (SLE). KBD4466 can be used in the study of autoimmune diseases.

KBD4466 (Compound 19) (1 mg/kg, p.o., once) inhibits the production of IL-6 and IFN-α in R848 (HY-13740 )-challenged mouse model[1].
KBD4466 (10 mg/kg, p.o., once a day, 14 weeks) improves disease symptoms in the BXSB/MpJ mouse lupus model[1].
