Embodiment 1
[0034] Embodiment 1: the preparation of formula (I) compound:
[0035] Using 10 kg of dried medicinal material from the root of Schisandra chinensis as raw material, it was heated and refluxed with 90% ethanol for 3 times, each time for 2 hours, and concentrated to obtain 1500 g of extract-like ethanol extract. The ethanol extract was suspended in water, and extracted 4 times with petroleum ether, 1000 mL each time. The extract from the petroleum ether extraction part was separated by silica gel (200-300 mesh) column chromatography, and gradient eluted with petroleum ether-ethyl acetate (the volume ratio of the eluent was 100:1-1:1), and the petroleum The eluted part with a volume ratio of ether-ethyl acetate of 100:3 was separated by silica gel (200-300 mesh) column chromatography, and petroleum ether-acetone (the volume ratio of the eluent was 100:1-1:1) Gradient elution, the eluted part with a volume ratio of petroleum ether-acetone of 100:3 was purified by Sephadex LH-20 ...
Embodiment 2
[0036] Example 2: In vitro growth inhibition test of the compound of formula (I) on human acute promyelocytic leukemia cell line HL-60:
[0037] HL-60 cells were cultured in 10% heat-inactivated fetal bovine serum, 100 IU / mL penicillin, 100 m g / mL streptomycin and 1 mmol / L L -Glutamine in RPMI1640 medium, 37 °C, 5% CO 2 Incubate in a saturated humidity incubator. Weigh trypan blue, add a small amount of distilled water to grind, add double distilled water to dilute to 4% storage concentration, filter with filter paper, and store at 4 °C. When used, this stock solution was diluted to a working concentration of 0.4% with PBS. Take the above cells (1'10 5 / mL) were inoculated in a 12-well plate, 2 mL per well. Add different concentrations of drugs to prepare a single cell suspension after incubation, take 50 mu L cell suspension added 50 mu 0.4% trypan blue solution in L, mix well, and observe under the microscope within 3 minutes, the dead cells are stained blue, while ...
