METHODS AND RESULTS:
In the present study, we identified Eriodictyol-7-O-glucoside as a novel nuclear factor E2-related factor 2 (Nrf2) activator using a high-throughput cellular screening method. This compound activated Nrf2 signaling pathway and was able to stabilize Nrf2 by delaying Nrf2 degradation, resulting in accumulation of Nrf2 protein and activation of the Nrf2-dependent protective response. Recent studies have suggested that activation of Nrf2 pathway would confer protection against cisplatin-induced toxicity. The protective role of Eriodictyol-7-O-glucoside in cisplatin-induced toxicity was investigated in a human renal mesangial cell line, HRMC. Cotreatment of HRMC cells with Eriodictyol-7-O-glucoside significantly improved cell survival under cisplatin exposure.
CONCLUSIONS:
These findings demonstrated the feasibility of using natural compounds targeting Nrf2 as a therapeutic approach to subvert the side effects of cisplatin in normal cells. | | Biochimie. 2010 Sep;92(9):1115-22. | | Antioxidant activity and phenolic profile of pistachio (Pistacia vera L., variety Bronte) seeds and skins.[Pubmed: 20388531] |
METHODS AND RESULTS:
By HPLC analysis, gallic acid, catechin, Eriodictyol-7-O-glucoside, naringenin-7-O-neohesperidoside, quercetin-3-O-rutinoside and eriodictyol were found both in pistachio seeds than in skins; furthermore, genistein-7-O-glucoside, genistein, daidzein and apigenin appeared to be present only in pistachio seeds, while epicatechin, quercetin, naringenin, luteolin, kaempferol, cyanidin-3-O-galactoside and cyanidin-3-O-glucoside are contained only in pistachio skins. The antioxidant activity of pistachio seeds and skins were determined by means of four different assays (DPPH assay, Folin-Ciocalteau colorimetric method and TEAC assay, SOD-mimetic assay). As expected on the basis of the chemical analyses, pistachio skins have shown to possess a better activity with respect to seeds in all tests. The excellent antioxidant activity of pistachio skins can be explained by its higher content of antioxidant phenolic compounds.
CONCLUSIONS:
By HPLC-TLC analysis, gallic acid, catechin, cyanidin-3-O-galactoside, Eriodictyol-7-O-glucoside and epicatechin appeared to be responsible for the antioxidant activity of pistachio skin, together with other unidentified compounds. |
