Description

IDO2-IN-1 is an orally active and potent Indoleamine 2,3-dioxygenase 2 (IDO2) inhibitor with an IC50 value of 112 nM. IDO2-IN-1 can be used for inflammatory autoimmunity research[1].

IC50 & Target

IDO1

411 nM (IC50)

IDO2

112 (IC50)

In Vitro

IDO2-IN-1 (compound 22) shows stronger inhibition on IDO2 (IC50 =112 nM) over IDO1 (IC50 =411 nM)[1].
IDO2-IN-1 inhibits hIDO1 expression (EC50=633 nM) in HeLa cell-based IDO1/kynurenine assay, co-incubated with hIFN-γ (100 ng/mL final concentration), which is used for producing N-formylkynurenine[1].

Cell Viability Assay[1]

Cell Line: HeLa cells line expressing hIDO1 induced by IFN-γ
Concentration: 1 nM-0.1 mM
Incubation Time: 48 hours
Result: Showed additional potency against IDO1 with an EC50 value of 633 nM.
In Vivo

The Adjuvant arthritis (AA) model and Collagen-induced arthritis (CIA) model have similar pathogenesis and pathological characteristics to human rheumatoid arthritis (RA).
IDO2-IN-1 (compound 22) (100 mg/kg; p.o.; once dose) exhibits excellent anti-inflammatory activity, higher than naproxen, a prescription drug reducing pain, swelling, and joint stiffness from arthritis[1].
IDO2-IN-1 (25, 50, 100 mg/kg; i.p.; once daily, for 19 d) exhibits excellent inhibitory effect on mice paw swelling, shows efficacy in a collagen-induced arthritis model in mice[1].
IDO2-IN-1 (30, 60, 120 mg/kg; i.p.; once daily, for 15 d) inhibits joint inflammation and displays potential effect in autoimmune arthritis improvement[1].

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.
