ETI60
Based on 1 Customer Validation
ETI60 is an orally active, selective TLR inhibitor that targets the nucleoside-binding Site I on TLR7 (IC50 = 0.68 μM) and TLR9 (IC50 = 0.12 μM), sparing surface TLRs (including TLR1/TLR2, TLR2/TLR6, TLR4 and TLR5). ETI60 potently inhibits endosomal TLR-mediated pro-inflammatory signaling with nanomolar activity in cellular, biophysical and in vivo assays. ETI60 modulates the expression of genes associated with inflammation. ETI60 effectively ameliorates symptoms in mouse models of psoriasis, and systemic lupus erythematosus (SLE). ETI60 can be used for autoimmune and inflammatory diseases research.

Actividad biológica
|
TLR7 0.68 μM (IC50) |
TLR9 0.12 μM (IC50) |
ETI60 (0-200 μM, 4-24 h) effectively inhibits TLR agonist (e.g., Imiquimod (IMQ) (HY-B0180) for TLR7, ODN2395 (HY-150743) for TLR9)-induced TNF-α production in mouse macrophages (RAW 264.7) and human B lymphoblasts (Daudi) cell lines in a dose-dependent manner, without inducing cytotoxic effects[1].
ETI60 (24 h) inhibits TLR3, TLR7, and TLR9 with IC50 values ranging from 20 to 300 nM, and TLR8 with an IC50 of approximately 2 μM, and inhibits TLR3, TLR7 and TLR8 in a concentration-dependent manner (from 31.2 nM to 10 μM)[1].
ETI60 (5-10 μM, 20 min-8 h) inhibits IMQ- or ODN2395-induced phosphorylation of MAPKs (p-ERK, p-JNK and p-p38), nuclear translocation of the NF-κB p65 subunit, Iκ-Bα degradation and IRF7 expression in RAW 264.7 cells[1].
ETI60 (10 μM, 2-4 h) attenuates the IMQ-induced upregulation of multiple inflammation-related genes, including IL1-β, CXCL2, IL18RAP, TNF, PDCD1, NLRP3, NFKBIZ, CCL3, CCL4, KDM6B, ZC3H12A, and PTGS2[1].

ETI60 (60 mg/kg, p.o., daily from day 2 to day 9) ameliorates psoriasis induced by IL-23 in mice[1].
ETI60 (30 mg/kg, p.o., daily for 39 days) effectively ameliorates symptoms in a mouse model of SLE[1].

-
Animal Model:Female MRL/MpJ-Faslpr/J lupus-prone mice (14 weeks old)[1]
-
Dosage:30 mg/kg
-
Administration:p.o., daily for 39 days
-
Result:Prevented weight gain or loss and decreased lymphnode weights.
Reduced alopecia and skin rashes compared with the vehicle and HCQ (60 mg/kg, P.O., daily for 39 days).
Increased complement C3 levels, indicating reduced disease activity and restored immune function.
Reduced serological markers associated with SLE, such as antinuclear antibody (ANA), anti-dsDNA antibodies and IgG in the kidney, compared to HCQ group.
Demonstrated significant reduction in SLE symptoms at half the dose of HCQ, suggesting high efficacy.
-
Animal Model:Female C57BL/6J mice (6 weeks old) induced with psoriasis via daily topical application of Aldara cream (IMQ, 62.5 mg/cm²) for 4 days post-shaving[1]
-
Dosage:60 mg/kg
-
Administration:p.o., daily from day 2 to day 5
-
Result:Significantly reduced the Psoriasis Area and Severity Index (PASI) scores, epidermal acanthosis, dermal thickness and keratinocyte proliferation.
Inhibited IL-17A and IL-23 expression and dermal inflammatory cell infiltration.
-
Animal Model:Female C57BL/6J mice (6 weeks old) induced with psoriasis via intradermal injection of recombinant murine IL-23 (500 ng) around the ear daily for 8 days[1]
-
Dosage:60 mg/kg
-
Administration:p.o., daily from day 2 to day 9
-
Result:Improved disease symptoms comparable to or superior to the positive control (anti-IL-17A antibody, 30 mg/kg, i.p., dose on day 2, 5, and 8), without significant differences in body weight.
Significantly decreased ear and epidermal thicknesses, CD68 expression and Ki-67 keratinocyte proliferation.
