Schisandrin A (Sch A) strongly inhibits microsomal midazolam 1-hydroxylation catalyzed by CYP3A, with an IC50 of 6.60 μM. The recovery of enzyme activity in the absence or presence of Schisandrin A is shown in dilution assay plots. The Ki value for Schisandrin A is obtained from the Dixon plots and is 5.83 μM. The inactivation of rat liver microsomal midazolam 1-hydroxylation activity by Schisandrin A in the presence of NADPH is found to be time- and concentration-dependent. The Kinact and Ki are estimated to be 0.134/min and 4.51 μM, respectively for Schisandrin A[1].

Protocol
For the inactivation of CYP3A4 activity, microsomes are preincubated with inhibitors (Schisandrin A, 2.4 μM, 7.2 μM and 12.0 μM; or Sch B) at 37°C for up to 15 min in the presence of NADPH. Reactions are initiated with the addition of substrate midazolam and incubated at 37°C for 10 min. The enzyme inactivation is analyzed. Duplicates are prepared and tested[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
Rats[2]
Healthy male Sprague-Dawley rats, weighing 250-280 g and 2-3 months of age, are used. The rats are randomly divided into five groups with 16 rats in each group. The animals are administered once daily for three consecutive days. The Schisandrin A-treated groups are administered intragastrically with doses of 32, 16 or 8 mg/kg of Schisandrin A (physiological saline as vehicle), and the rats are similarly administered with equal volume of vehicle in the negative control group and Ketoconazole (75 mg/kg) in the positive control group. All animals are allowed free access to food but are fasted overnight before scarification to reduce the intestinal content, and each group is randomly divided into two parts with eight rats in each part[2].
