实验参考方法
In Vitro

In vitro activity: Diosmetin inhibits 3H-dopamine uptake in neuroblastoma cells, as well as in small-cell lung carcinoma cells, which is be responsible for the increased vascular tone observed in vivo after treatment with Diosmetin. Moreover, Diosmetin also removes iron from iron-loaded hepatocytes revealed a good relationship between this iron-chelating ability and the cytoprotective effect. Other studies proves that Diosmetin is a cytochrome P450 inhibitor, thus inhibiting carcinogen activation and and causing pharmacokinetic interactions with co-administered drugs metabolized.

Cell Assay: In MCF-7 cells, at 24 h after the incubation of diosmetin, CYP1A1 mRNA was increased in a dose-dependent manner. In MCF-7 cells, diosmetin at 2.5 μM modestly increased CYP1A1 enzyme activity, with an activity increase in cells, while diosmetin at 5 μM did not increase the enzyme activity compared to controls in cells. Compared with controls, diosmetin dose-dependently increased the capacity of nuclear extracts to bind an oligonucleotide containing the AhR-binding sequence of CYP1A1.

In VivoPretreatment with diosmetin significantly reduces serum levels of amylase and lipase; the histological injury; the secretion of tumor necrosis factor (TNF)-α, interleukin (IL)-1β, and IL-6; myeloperoxidase (MPO) activity, trypsinogen activation peptide (TAP) level, the expression of inducible nitric oxide synthase (iNOS); and the nuclear factor (NF)-κB activation in cerulein-induced acute pancreatitis.
Animal modelMice: Experimental acute pancreatitis is induced in mice by seven intraperitoneal injection of cerulein (50 μg/kg) at hourly intervals. Diosmetin (100 mg/kg) or vehicle is pretreated 2 h before the first cerulein injection. After 6 h, 9 h, 12 h of the first cerulein injection, the severity of acute pancreatitis is evaluated biochemically and morphologically
Formulation & Dosage100 mg/kg
