Abstract EN
The effects of Buchang Naoxintong Capsules (BNCs) on S-mephenytoin 4′-hydroxylation activities in human liver microsomes in vitro were assessed.
Human liver microsome was prepared by different ultracentrifugation.
Human liver microsome incubation experiment was carried out to assay BNC on S-mephenytoin 4′-hydroxylation activities.
The 4′-hydroxylation of S-mephenytoin, a representative substrate toward CYP2C19, was increased by phenytoin sodium (positive control).
After the incubation, the metabolites of the substrates (4′-OH-mephenytoin) were determined by HPLC.
Results showed that both phenytoin sodium and BNC showed obvious increase effect on CYP2C19.
The enzymatic reaction of BNC was observed with concentrations ranging from 5 μg/mL to 250 μg/mL.
Compared to blank, the increase effect of BNC showed significant difference from the beginning of concentration of 150 μg/mL (P<0.001).
The conclusion was that BNC showed obvious increase effect on the catalytic activities of drug-metabolising CYP2C19 enzyme.
