Embodiment 1
[0022]
[0023] Take the above compound as an example to specifically describe the synthesis process:
[0024] Step S1: Using DMF as a solvent, put a small amount of 9(10H)-acridone (98wt%) (1g about 5.1mmol) into a round bottom flask, place it on a constant temperature magnetic stirrer, and then add (0.41g about 10.2 mmol) sodium hydride, stirred at room temperature for about 1.5 h, then added dropwise (3.1 mL about 30.6 mmol) of 1.3-dibromopropane to the reaction system, placed in an oil bath at 80° C. for about 24 h, and took it out. Wait until the reaction system is down to room temperature, extract with ethyl acetate, after the TLC spot plate monitors the reaction is complete, dry the organic phase, rotary evaporate and mix the sample, and separate through column chromatography to obtain compound 1 acridine bromide (0.95g about 3mmol, yield 59%).
[0025] 1 HNMR (600MHz, CDCl 3 )δ8.52(d, J=7.8Hz, 2H), 7.68(t, J=7.8Hz, 2H), 7.50(d, J=8.4Hz, 2H), 7.24(t, J=7.4Hz, 2H) ...

Embodiment 3
[0045] Activity data analysis of preliminary determination of some compounds:
[0046] The anticancer activity of the synthesized galactose-containing acridone derivatives was determined by MTT method. Human gastric cancer cells MGC-803 and human breast cancer cells MCF-7 were respectively inoculated in the corresponding medium containing 10 wt% fetal calf serum, at 37 °C, with a volume fraction of 5% CO 2 and saturated humidity conditions, the logarithmic growth phase cells were inoculated into 96-well culture plates, incubated in the incubator for 24 hours, and replaced with different concentrations of compounds (0, 3, 6, 9, 12, 15, 18 μM / L) complete culture medium. After culturing for 72 hours, add 20 μL of MTT (5 mg / mL), continue to cultivate for 4 hours, then slowly absorb the supernatant, add 150 μL of DMSO, shake and shake for 10 minutes to fully dissolve the crystals, and then use a microplate reader to detect the absorbance.
