Biochem/physiol Actions
FC-99 is a benzenediamine derivative that inhibits LPS-induced IRAK4 phosphorylation/activation and downstream signaling events (5-45 μM; murine RAW 264.7 & peritoneal macrophages), including IRAK1 (a TLR3 pathway negative regulator) degradation, p38/ERK/JNK activation, and cytokines production. FC-99 inhibits RSV replication (50 μM; A549) and poly(I:C)-indued IRF3/IFN-α/JAK/STAT1 signalling in cultures (0.5-50 μM; murine peritoneal macrophages), and ameliorates sepsis induction following caecal ligation puncture (CLP) in mice in vivo (100/70/32.5% motality in 7 days with 0/30/100 mg/kg i.p. 2 h prior to CLP).
FC-99 is known to affect the levels of serum immunoglobulin. It might be therapeutically beneficial in systemic lupus erythematosus.

The liver is a vital target for sepsis-related injury, leading to inflammatory pathogenesis, multiple organ dysfunction and high mortality rates. Monocyte-derived macrophage transformations are key events in hepatic inflammation. N1-[(4-methoxy)methyl]-4-methyl-1,2-benzenediamine (FC-99) previously displayed therapeutic potential on experimental sepsis. However, the

Systemic lupus erythematosus (SLE) is an autoimmune disease with prominent chronic inflammatory aspects. Plasmacytoid dendritic cells (pDCs), which are the principal interferon-α (IFN-α)-producing cells, have known to be critically involved in SLE pathogenesis. Our previous research demonstrated that a benzenediamine
