生物活性

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[1].

Animal Model: R848 (25 μg per mouse, i.p., 1 h, 4 h, 8 h, 16 h, 24 h after administration of compound 19)-challenged mouse (female C57BL/6 mice, 6-8 weeks old) model [1]
Dosage: 1 mg/kg
Administration: p.o., once
Result: Inhibited the production of IL-6, with an inhibition rate of 99.4% at 1 hour, more than 50% at 16 hours, and more than 90% at 8 hours.
Inhibited the production of IFN-α, with an inhibition rate of 98% at 16 h, 69% at 24 h.
Animal Model: SLE model using BXSB/MpJ transgenic mice (female BXSB/MpJ mice, 7 weeks).[1]
Dosage: 10 mg/kg
Administration: p.o., once a day, 14 weeks
Result: Improved survival rates ,the survival rate reached 100%.
Relieved splenomegaly and lymphadenopathy, and reduced plasma levels of autoantibodies, including anti-histone antibodies, anti-ribosomal P (anti-RiboP), and anti-double-stranded DNA (anti-dsDNA).
Reduced urine microalbumin (MALB), urine microalbumin to creatinine ratio (MALB/CREA), and urine total protein (UTP) levels.
Improved kidney swelling.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
