    Description

    Diphenyleneiodonium chloride is a NADPH oxidase (NOX) inhibitor and also functions as a TRPA1 activator with an EC50 of 1 to 3 μM. Diphenyleneiodonium chloride selectively inhibits intracellular reactive oxygen species.

    IC50 & Target

    NOX[1]
    EC50: 1 to 3 μM (TRPA1)[1]

    In Vitro

    Diphenyleneiodonium chloride is a NADPH oxidase (NOX) inhibitor and also functions as a TRPA1 activator with an EC50 of 1 to 3 μM. Application of Diphenyleneiodonium chloride to HEK-TRPA1 cells at a concentration ranges of 0.03 to 10 μM effectively induces a Ca2+ response. However, Diphenyleneiodonium chloride fails to evoke a Ca2+ response in control HEK cells, even at a relatively high dose of 10 μM[1]. When Diphenyleneiodonium chloride is included in the co-cultures, lipopolysaccharide (LPS)-induced preOL apoptosis is significantly inhibited. Treatment with Diphenyleneiodonium chloride is found to significantly attenuate the LPS-induced O2- production by 2.0-fold, reducing it to within 27% of the controls[2].

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

    In Vivo

    Intraplantar injection of 2 mM Diphenyleneiodonium chloride to the hindpaw causes licking or biting behavior[1]. Diphenyleneiodonium chloride treatment immediately or 24 h after lipopolysaccharide (LPS) injection significantly attenuates the LPS-induced loss of O4 positive cells. Treatment with Diphenyleneiodonium chloride either immediately or 24 h after LPS injection significantly ameliorates the LPS-induced disorganization of the white matter nerve fibers. However, treatment with DPI 48 h after LPS injection does not appear to correct the LPS-induced white matter damage. DPI treatment either immediately or 24 h after LPS injection significantly reduces the accumulation of both gp91phox and p67phox in the membrane fraction[2].

    [2]

    Purified microglia and preOLs are co-cultured using a Transwell culture system. Co-cultured cells are divided into three groups: control, lipopolysaccharide (LPS)-activated, and LPS plus Diphenyleneiodonium chloride. Microglia are cultured in Transwells over established preOL layers and exposed to either LPS (100 ng/mL), LPS+Diphenyleneiodonium chloride (10 μM) or untreated. The medium supernatants and cellular protein fractions from the co-cultures are then collected for further analysis after 48 h incubation[2].

    Animal Administration
    [1]

    The ddy mice (6 to 7 wk of age) are individually placed in transparent cages for 30 min before experiments. An intraplantar injection of 10 μL Diphenyleneiodonium chloride (2 mM, solvent: Kolliphor EL with 20% DMSO) is then injected into the right hindpaw with or without intraperitoneal administration with HC030031 (300 mg/kg at 0.5 h prior to injection of Diphenyleneiodonium chloride; solvent: saline with 0.5% methyl cellulose). The time spent licking or biting the injected paw is recorded for 45 min after injection[1].

    • 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.
