Problems solved by technology

STAT3 inhibitors include natural products, peptides and peptidomimetics, and small molecule inhibitors; natural product STAT3 inhibitors have complex structures and few studies; peptides and peptidomimetics have good activity, but due to low bioavailability in vivo, It is still very difficult to develop into clinical drugs; therefore, small molecule inhibitors with good activity, physical and chemical properties, and ideal pharmacokinetic properties are hot spots in the research of STAT3 inhibitors

Embodiment 3

[0051] Embodiment 3: Function test of benzodifuranone compound AtrA

[0052] 1. AtrA cytotoxicity test

[0053] CCK8 assay was used to determine the effect of compound AtrA on the viability of gastric cancer cell lines HGC27, MGC803, BGC823, AGS and normal gastric epithelial cell line GES-1.

[0054] Culture of human gastric cancer cell lines:

[0055] Human gastric cancer cell lines MGC803, BGC823, AGS, HGC27 and human normal gastric epithelial cell line GES-1 were obtained from the Institute of Cells, Chinese Academy of Sciences (Shanghai, China). These cells are commercially available and can also be purchased from the ATCC. All cell lines were cultured in RPMI1640 containing 10% fetal bovine serum and 1% penicillin / streptomycin at 37 °C, 5% CO 2 cultured in an incubator.

[0056] Cell viability assay: Gastric cancer cell lines MGC803, BGC823, AGS and HGC27 and normal gastric epithelial cell line GES-1 were cultured overnight in 96-well plates, and then treated with dif...

Abstract

The invention discloses a benzodifuranone compound with antitumor activity and a preparation method and application thereof. The benzodifuranone compound has obvious cytotoxicity to a gastric cancer cell line.

Description

technical field [0001] The invention relates to the field of compounds, in particular to a benzodifuranone compound with antitumor activity, a preparation method and use thereof. Background technique [0002] Cancer is a general term for a large class of malignant tumors. Cancer cells are characterized by unlimited and endless proliferation, which consumes a large amount of nutrients in the patient's body; cancer cells release a variety of toxins, causing a series of symptoms in the human body; cancer cells can also be transferred to grow and multiply throughout the body, Lead to body weight loss, weakness, anemia, loss of appetite, fever, and severe damage to organ function. [0003] Due to their special living environment, marine microorganisms have formed unique genetic metabolic mechanisms and chemical defense mechanisms during the evolution process of adapting to the environment, and are currently the main source of new structures or new active natural products. Marin...
