The aim of this study was to prove the neuroprotective effect of 5,7-Dihydroxychromone (DHC) through the Nrf2/ARE signaling pathway. To elucidate the mechanism, we investigated whether 6-hydroxydopamine (6-OHDA)-induced neurotoxicity in SH-SY5Y cells could be attenuated by DHC via activating the Nrf2/ARE signal and whether 5,7-Dihydroxychromone could down-regulate 6-OHDA-induced excessive ROS generation |

Anti-diabetic properties of Daphniphyllum macropodum fruit and its active compound.[Pubmed:25130743]
Biosci Biotechnol Biochem. 2014;78(8):1392-401.
We evaluated in vitro anti-diabetic activities of 497 native plants of Jeju Island (South Korea) by measuring the induction of adipocyte differentiation. Among the plants, Daphniphyllum macropodum fruit extract (DME) had the highest peroxisome proliferator-activated receptor gamma (PPARgamma) agonist activity and was therefore selected as a potential source of anti-diabetic agents. To elucidate the active components of DME, constituent compounds were purified and their effects on the adipocyte differentiation were studied. Using activity-guided fractionation, four compounds were isolated from DME and their adipogenic effects were evaluated. Among the compounds isolated, 5,7-Dihydroxychromone potently induced the differentiation of mouse 3T3-L1 preadipocytes. DME and 5,7-Dihydroxychromone increased PPARgamma and liver X receptor alpha (LXRalpha) mRNA expression levels. To determine whether the adipogenic effects we observed might affect serum glucose levels, we undertook in vivo experiment using streptozotocin-/high-fat diet-induced type 2 diabetes mouse model. DME supplementation reduced serum glucose, total cholesterol, and triacylglycerol levels in diabetes mice. These results suggest that DME may be useful for the prevention and treatment of type 2 diabetes mellitus. Moreover, it was proposed that 5,7-Dihydroxychromone isolated from DME is one of the active compounds that may contribute to regulate blood glucose levels.
Neuroprotection against 6-OHDA-induced oxidative stress and apoptosis in SH-SY5Y cells by 5,7-Dihydroxychromone: Activation of the Nrf2/ARE pathway.[Pubmed:25818191]
Life Sci. 2015 Jun 1;130:25-30.
AIMS: The aim of this study was to prove the neuroprotective effect of 5,7-Dihydroxychromone (DHC) through the Nrf2/ARE signaling pathway. To elucidate the mechanism, we investigated whether 6-hydroxydopamine (6-OHDA)-induced neurotoxicity in SH-SY5Y cells could be attenuated by DHC via activating the Nrf2/ARE signal and whether DHC could down-regulate 6-OHDA-induced excessive ROS generation MAIN METHODS: To evaluate the neuroprotective effect of DHC against 6-OHDA-induced apoptosis, FACS analysis was performed using PI staining. The inhibitory effect of DHC against 6-OHDA-induced ROS generation was evaluated by DCFH-DA staining assay. Additionally, translocation of Nrf2 to the nucleus and increased Nrf2/ARE binding activity, which subsequently resulted in the up-regulation of the Nrf2-dependent antioxidant gene expressions including HO-1, NQO1, and GCLc, were evaluated by Western blotting and EMSA. KEY FINDINGS: Pre-treatment of DHC, one of the constituents of Cudrania tricuspidata, significantly protects 6-OHDA-induced neuronal cell death and ROS generation. Also, DHC inhibited the expression of activated caspase-3 and caspase-9 and cleaved PARP in 6-OHDA-induced SH-SY5Y cells. DHC induced the translocation of Nrf2 to the nucleus and increased Nrf2/ARE binding activity which results in the up-regulation of the expression of Nrf2-dependent antioxidant genes, including HO-1, NQO1, and GCLc. The addition of Nrf2 siRNA abolished the neuroprotective effect of DHC against 6-OHDA-induced neurotoxicity and the expression of Nrf2-mediated antioxidant genes. SIGNIFICANCE: Activation of Nrf2/ARE signal by DHC exerted neuroprotective effects against 6-OHDA-induced oxidative stress and apoptosis. This finding will give an insight that activating Nrf2/ARE signal could be a new potential therapeutic strategy for neurodegenerative disease.
