Description | 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). | |

Targets |
|
|
In vitro | DPI inhibits the activity of NADPH oxidase, nitric oxide synthase, xanthine oxidase and NADPH cytochrome P450 oxidoreductase[4]. Femtomolar concentrations of DPI exert potent anti-inflammatory and neuroprotective effects by inhibiting microglial activation through the inhibition of ERK-regulated PHOX activity[1]. DPI 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]. DPI treatment 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, DPI 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. |
