生物活性

製品説明 DPI (Diphenyleneiodonium chloride) is an inhibitor of NADPH oxidase and also a potent, irreversible, and time-, temperature-dependent iNOS/eNOS inhibitor. Diphenyleneiodonium chloride (DPI) also functions as a TRPA1 activator and selectively inhibits intracellular reactive oxygen species (ROS).
in vitro

DPI (Diphenyleneiodonium chloride) inhibits the activity of NADPH oxidase, nitric oxide synthase, xanthine oxidase and NADPH cytochrome P450 oxidoreductase[4].

Femtomolar concentrations of this compound exert potent anti-inflammatory and neuroprotective effects by inhibiting microglial activation through the inhibition of ERK-regulated PHOX activity[1].

It has frequently been used to inhibit ROS production mediated by various flavoenzymes, including NAD(P)H oxidase, quinone oxidoreductase, cytochrome P450 reductase and nitric oxide synthase[2].

NADPH, NADP+, and 2'5'-ADP blocks the inhibitory action of DPI[3].

Treatment with this compound in ARPE-19 cells evoked a dose- and time-dependent growth inhibition, and also induced DNA fragmentation and protein content of the proapoptotic factor Bax. In addition, it significantly induced the expression and phosphorylation of p53, which induces proapoptotic genes in response to DNA damage or irreparable cell cycle arrest. ROS have been implicated as a key factor in the activation of p53 by many chemotherapeutic drugs[4].

in vivo

Diphenyleneiodonium (DPI), an NADPH oxidase inhibitor, inhibited the production of pro-inflammatory cytokines, (TNF-α and IL-6), reduced macrophage infiltration and classical polarization, and induced the ROS generation.

実験の流れ

ARPE-19 cells are plated at 1×106 cells per 60-mm dishes and incubated for 24 h. Cells are cultured in presence or absence of different concentrations of DPI (Diphenyleneiodonium chloride) in fresh DMEM/F12 medium supplemented with 10% FBS. After incubation, the cells are trypsinized, washed with phosphate-buffered saline (PBS) and the viable cells were scored by the trypan blue dye exclusion method using a hemocytometer.
