The study of Raddeanin A cerebrovascular endothelial cell trafficking through P-glycoprotein.

As one of the natural triterpenoids isolated from Anemone Raddeana Regel, Raddeanin A (RA) has been confirmed to possess therapeutic effects against multiple tumorigeneses, especially for the onset of glioblastoma and growth in human brains. However, the mechanism by which this happens remains poorly understood in terms of the vascular endothelium trafficking routine of RA through the brain-blood barrier (BBB). To seek such answers, human brain microenvironment endothelial cells (HBMECs) were used to stimulate the microenvironment in vitro, and to explore the intracellular accumulation of RA.

Comparison of the acute toxicity, analgesic and anti-inflammatory activities and chemical composition changes in Rhizoma anemones Raddeanae caused by vinegar processing.

Background: As the dry rhizome of Anemone raddeana Regel, Rhizoma Anemones Raddeanae (RAR), which belongs to Ranunculaceae, is usually used to treat wind and cold symptoms, hand-foot disease and spasms, joint pain and ulcer pain in China. It is well known that the efficacy of RAR can be distinctly enhanced by processing with vinegar due to the reduced toxicity and side effects. However, the entry of vinegar into liver channels can cause a series of problems.

Synergy of Raddeanin A and cisplatin induced therapeutic effect enhancement in human hepatocellular carcinoma.

Cisplatin is a main compound for human hepatocellular carcinoma (HCC) chemotherapies, but it has certain cytotoxicity during applications. To release that, combining with other drugs are being as a regular plan in clinic. In our present study, we are focusing on one of active monomers extracted from Anemone Raddeana Regel, Raddeanin A (RA), which is on behalf of the same character like cisplatin in the tumor remedies.

[CYP450 enzyme inhibition of berberine in pooled human liver microsomes by cocktail probe drugs].

Objective: To investigate the effect of CYP450 enzyme inhibition of berberine in pooled human liver microsomes by cocktail probe drugs.

Method: Cocktail probe drugs method has been established, an LC-MS/MS analytical method has been established to determine the five probes of midazolam, phenacetin, dextromethorphan, tolbutamide, chlorzoxazone and the internal standard was benzhydramine to evaluate the effect of CYP450 activity following administration of berberine in pooled human liver microsomes.

Result: Compared with control group, the pharmacokinetics of midazolam, phenacetin and tolbutamide were no significant differences, but the pharmacokinetics of chlorzoxazone was significantly decreased.
