| 生物活性 | Ethyl ferulate, a naturally lipophilic derivative of ferulic acid originally derived from Rhizoma Chuanxiong, induces heme oxygenase-1 (HO-1) and protects rat neurons against oxidative stress[1]. Ethyl ferulate also protects neurons against amyloid β peptide (1-42)-induced oxidative stress and neurotoxicity[2]. |
| In Vitro | We constructed hypoxia models induced by cobalt chloride (CoCl?) in ARPE - 19 cells and Rhesus choroid - retinal vascular endothelial (RF/6A) cells in vitroIn this work, we demonstrated that EF treatment inhibited hypoxia - induced vascular endothelial growth factor A (VEGFA) expression in ARPE - 19 cells and abrogated hypoxia - induced tube formation in RF/6A cells.[5]。Western Blot Analysis[5]:Cell Line: RPE cells (induced by 150 μM CoCl2 for 12 h);Concentration: 40 μM;Incubation Time: 2 h;Result:Increased Nrf-2 expression and nuclear translocation.Decreased Keap-1 expression, Aand increased HO-1 and NQO-1 expression.Reduced hypoxia-induced HIF-1α and VEGFA expression. |
| 细胞实验 | We constructed... a retinal neovascularization model in oxygen - induced retinopathy (OIR) mice in vivo.As expected, intravitreal injection of EF significantly suppressed retinal neovascularization in a dose - dependent manner in OIR retinas.[5]。Animal Model:LPS (0.5 mg/kg)-induced acute lung injury mice model[3];Dosage:15 and 30 mg/kg;Administration:i.p., twice a day for 5 days;Result:Reduced leukocyte infiltration.Reduced MPO activity, mRNA levels and secretion of TNF-α and IL-6. |
