  • mice Male C57BL/6 mice aged 6-8 weeks were used, and the purified recombinant plasmid pHBV1.3 (10 ⁇ g) was dissolved in PBS. Each mouse was injected in a volume of about 10% of its body weight through the tail vein at 3-8 s. Injection into mice. After 24 hours of injection of the plasmid, serum HBV DNA was taken from the eyelids, and the serum DNA of the model mice was selected and grouped into a blank control group, a vehicle control group, and a test group. Each group of mice was administered by intragastric administration for 6 days, once a day. The mouse serum was taken at 1, 3, 5, and 7 days after the injection, and the liver tissue samples were taken from the 7th day. The HBV DNA copy number in the serum and liver of the mice was detected by real-time quantitative PCR. The specific results are shown in Table 4.
  • 300 ⁇ L of the final incubation system contained 30 ⁇ L of human liver microsomes (protein concentration: 0.15 mg/mL), 30 ⁇ L of NADPH + MgCl 2 , 3 ⁇ L of substrate (acetonitrile), and 237 ⁇ L of PBS buffer. Make 2 servings, each serving 0.3 mL. Each tube was first prepared with a total volume of 270 ⁇ L of substrate and enzyme mixture, and NADPH was preincubated at 37 ° C for 5 min, then added with 30 ⁇ L of NADPH + MgCl 2 mixed solution, respectively at 0, 10, 30, 60 min. 50 ⁇ L of the reaction was stopped with 300 ⁇ L of ice-acetonitrile containing an internal standard.
  • Sample preparation 50 ⁇ L of incubation sample, 300 ⁇ L of ice-acetonitrile containing internal standard diazepam, vortexing for 5 min, centrifugation (12000 rpm, 4 ° C) for 10 min. 75 ⁇ L of the supernatant was aspirated into a 96-well plate and diluted with 75 ⁇ L of ultrapure water, and 0.5 ⁇ L was injected for LC-MS/MS analysis. The specific results are shown in Table 5.
  • SD rats weighing 180-220 g, were adapted to 3 to 5 days and randomly divided into 2 groups, 3 in each group, and the test compounds were administered at a dose of 30 mg/kg.
  • test animals SD rats
  • the test animals were fasted for 12 h before administration, and given food for 4 h after administration. Drinking water was free before and after the experiment and during the experiment.
