ETI60

ETI60 is an orally active selective TLR inhibitor that targets the nucleoside-binding sites I of TLR7 (IC50 = 0.68 μM) and TLR9 (IC50 = 0.12 μM) without affecting surface TLRs (including TLR1/TLR2, TLR2/TLR6, TLR4, and TLR5) . It demonstrates nanomolar activity in cell-based, biophysical, and in vivo assays, effectively inhibiting endosomal TLR-mediated pro-inflammatory signaling. ETI60 modulates the expression of genes related to inflammation and significantly improves symptoms in mouse models of psoriasis and systemic lupus erythematosus (SLE) . ETI60 is applicable in studies related to autoimmune and inflammatory diseases.
