背景说明 |
Diosmin 是芳烃受体 (AhR) 的激动剂。 |
生物活性 |
Diosmin is a flavonoid found in a variety of citrus fruits and also an agonist of the aryl hydrocarbon receptor (AhR).[1-2] |
In Vitro |
Treatment with Diosmin causes a dose dependent increase in the amount of adducts formed (up to a 7-fold increase in adducts at 5 μM Diosmin). At 5 μM, Diosmin increases the cytotoxicity of 7,12-dimethylbenz(a)anthracene, shifting the IC50 from an estimated 1.2 μM to 400 nM. Diosmin is not cytotoxic in itself at the concentrations tested. Diosmin causes an increase in CYPIAI activity in MCF-7 cells in a time- and dose-dependent fashion. Diosmin causes a dose-dependent increase in CYPIAI mRNA after 24 h of incubation, causes a long-lasting increase in CYPIAI mRNA accumu lation that reaches its peak after 48 h of incubation[1]. |
In Vivo |
Diosmin significantly decreases the malondialdehyde (MDA) levels and increases the activities of total-superoxide dismutase (T-SOD), glutathione peroxidase (GSH-Px), and catalase (CAT) in the retina of rats compare with the ischemia group (P[2]. |
细胞实验 |
MCF-7 cells are plated at 25,000 cells/well in 24-well plates. After 24 h, the medium is changed to medium containing 5 μM Diosmin. After an additional 24 h, the medium is again changed with medium containing 5 μM Diosmin. After 3 days, the total cell growth is assessed by sulforhodamine[1]. |
动物实验 |
Healthy male Wistar rats (n=112) weighing 180 to 200?g each are used in this study. The animals are randomly assigned to the following 4 groups, which include combinations of the ischemia/reperfusion (I/R) injury model or sham injury with the i.g. administration of Diosmin or vehicle solution: sham+vehicle (SV) group, sham+Diosmin (SD) group, model+vehicle (MV) group, and model+Diosmin (MD) group. For intragastric administration, 5?mL of 2% Diosmin per kilogram weight of the rat, or the same volume of vehicle solution, is administered intragastrically 30?min before the onset of ischemia, and then daily after I/R injury until the animals are sacrificed. Using an overdose of anesthesia, 8 rats from each group are sacrificed 24?h after I/R injury, and their eyeballs harvested for determination of the malondialdehyde (MDA) level and the activities of total-superoxide dismutase (T-SOD), glutathione peroxidase (GSH-Px), and catalase (CAT). At 7 days post-I/R injury, electroretinograms (ERGs) are recorded in 6 rats per group. Meanwhile, 6 rats in each group are randomly chosen for retrograde labeling of retinal ganglion cells (RGCs) , and the remaining 8 rats from each group are histopathologically examined[2]. |
