Description

YE6144 free base is a selective prototypical interferon regulatory factor 5 (IRF5) inhibitor. YE6144 free base suppresses the disease course and is especially effective in remission maintenance in a mouse model of systemic lupus erythematosus (SLE). YE6144 free base can be used for SLE research[1].

IC50 & Target[1]

IRF5

 

In Vitro

YE6144 (1 or 3 μM; 30 min) free base inhibits the phosphorylation of IRF5 in both human PBMCs and mouse splenocytes[1].
YE6144 (0-10 μM; 30 min) free base inhibits the production of type I IFNs with an IC50 of approximately 0.09 μM in human HC PBMCs[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Western Blot Analysis[1]

Cell Line: Human HC PBMCs and mouse WT splenocytes
Concentration: 1 μM (PBMCs) and 3 μM (splenocytes)
Incubation Time: 30 min
Result: Inhibited the phosphorylation of IRF5.

RT-PCR[1]

Cell Line: Mouse WT splenocytes
Concentration: 3 μM
Incubation Time: 30 min
Result: Induction of type I IFN genes, Ifnb1 and Ifna stimulated by TLR7 ligands or TLR9 ligands was remarkably weakened.
In Vivo

YE6144 (40.0 mg/kg; s.c.; once) free base suppresses the progression of mouse systemic lupus erythematosus[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model: NZB/W F1 mouse model of systemic lupus erythematosus (SLE)[1]
Dosage: 40.0 mg/kg
Administration: s.c.; once
Result: Suppressed the exacerbation of autoantibody production.
Splenomegaly and renal dysfunction were also suppressed by the treatment after disease onset.

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.
