產品描述

二苯基氯化碘鹽(Diphenyleneiodonium Chloride, DPI)是一種不可逆的iNOS和eNOS抑制劑,IC50分別是50nM和0.3μM,其抑制是有效的、不可逆的,時間和溫度依賴性的。NADPH,NADP+和2'5'-ADP能夠阻斷DPI的抑制活性。類似的,FAD或FMN能保護NOS不被DPI抑制[1]。DPI結合并抑制中性粒細胞NADPH氧化酶[2]。DPI是一種GPR3激動劑(EC50=1μM)。通過GPR3(但不是GPR6或GPR12)活化腺苷酸環化酶,能夠誘導鈣動員和β-arrestin受體內在化[3]。DPI抑制IL-1β誘導的NFκB活化[4]。嚙齒類模型中預防早期酒精性肝損傷。

體外研究(細胞實驗):

細胞類型(Cell type):U2OS cells

藥物配制(Preparation):DPI was dissolved in DMSO to make stock solution and stored at -20℃.

實驗方法(Assay):U2OS cells were seeded onto glass coverslips in 24-well plates and transfected with plasmids encoding FLAG-GPR3-GFP. Thirty-six hours later, cells were changed into Dulbecco’s modified Eagle’s medium containing 0.5% FBS at 37°C for 2 hours followed by 1-hour incubation in mediacontaining DPI (10 μM) or vehicle [0.1% dimethylsulfoxide (DMSO)].Cells were then washed three times with phosphate-buffered saline and fixed in 4% paraformaldehyde. After counterstaining of nuclei with Hoechst dye 33342, cells were examined using an FV10i confocal microscope.

體內研究(動物模型):

動物模型(Animal Model):ddy mice (6–7 wk of age)

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