  • Illumination test an appropriate amount of test sample was put in a flat weighing bottle in the form of a thin layer of ⁇ 5 mm, and the sample in the flat weighting bottle without sealing was placed in light box (with UV) under the condition of illumination of 4500 ⁇ 500lx, UV ⁇ 0.7 w/m 2 for 10 days. Appearance, impurity and purity of the samples were detected respectively at the 5 th and 10 th day by sampling. Results were as shown in table 8 and table 9.
  • test compounds were administered intragastrically at a dosage of 2.5 mg/kg, 5 mg/kg or 10 mg/kg.
  • Blood samples of foreleg-vein were taken at 0.083, 0.25, 0.5, 1, 2, 4, 6, 8 and 24 hours after the administration, and collected in anticoagulation tube with EDTA-K 2 .
  • the test compounds were extracted from plasma samples by liquid-liquid extraction. Then quantitative analysis was performed on a triple-quadrupole tandem mass spectrometer using multiple reaction monitoring (MRM) .
  • Pharmacokinetic parameters were calculated using a noncompartmental method by WinNonLin 6.1 software. Results were as shown in table 10:
  • test results showed that, the test compound prepared from example of the invention had good pharmacokinetic properties in test animals, specifically for the higher exposure level and longer half-life, which were shown that the compounds prepared from examples 1-4 had better absorption, longer half-life, and the administration interval can be appropriately prolonged, the number of times of administration can be reduced.
  • a dry glass weighing bottle (the outer diameter was 50 mm and height was 15 mm) with a plug was placed in a suitable thermostatic drier at 25 °C ⁇ 1 °C (saturated solution of ammonium chloride or ammonium sulfate were placed on the bottom, and the relative humidity was 90% ⁇ 2%) on the day before the experiment, and weighed precisely (m 1 ) .
  • the appropriate amount of the sample was plated into the weighing bottle, wherein the thickness of the sample typically was about 1 mm, and the sample was weighed precisely (m 2 ) .
  • the weighing bottle was open and placed with the plug in the above constant temperature and humidity condition for 24 hours.
  • the weighing bottle was capped with plug, and then weighed precisely (m 3 ) , and the weight gain percentage was calculated (%) .
  • Hygroscopicity characteristics the percentage (%) of hygroscopic weight gain.
