Embodiment

[0013] The lung cancer cells A549 or XWLC-05 cells in the logarithmic growth phase were inoculated in a 96-well plate, and sodium arsenite was dissolved in PBS, with 1000 cells per well. Set CO 2 Samples were added after 24 hours of incubation at 37°C in an incubator. 10 μL PBS solution was added to the control group; 10 μL sodium arsenite solution was added to the sodium arsenite group; 10 μL test substance solution was added to the Niclosamide group; 5 μL test substance solution and 5 μL sodium arsenite solution were added to the combined drug group. The final concentrations of sodium arsenite and Niclosamide are μmol L -1 , each group was set up with 6 multiple wells, and each experiment was repeated 3 times. Put in 37°C CO 2 in the incubator. After 5 days, add 20 μL MTS solution, 37°C CO 2 Continue to incubate in the incubator for 2 hours, and measure the absorbance (A) at 490 nm with an automatic microplate reader. All of the above were completed under the funding o...

Abstract

The invention discloses a pharmaceutical composition containing an inorganic arsenic compound and application of the pharmaceutical composition. The pharmaceutical composition contains the inorganic arsenic compound and Niclosamide and is used for preparing a cancer treatment medicine. Niclosamide has the molecular formula of C13H8Cl2N2O4 and the CAS number of 50-65-7. The pharmaceutical composition has a stronger cancer cell killing function than that of independent use of the inorganic arsenic compound or Niclosamide. The therapeutic dose of the inorganic arsenic compound is reduced, the cancer inhibition effect is enhanced, and the systematic poisonousness of the inorganic arsenic compound is effectively reduced.

Description

technical field [0001] The invention relates to a pharmaceutical composition containing Niclosamide and an inorganic arsenic compound and its application, in particular to a pharmaceutical composition containing an inorganic arsenic compound and Niclosamide and its application in the preparation of medicines for treating cancer. Background technique [0002] In 1971, Han Taiyun of the First Affiliated Hospital of Harbin Medical College transformed traditional Chinese medicine containing arsenic into a drug for treating leukemia. In 1973, Zhang Tingdong, Zhang Peng, etc. applied "Ailing No. 1" to treat chronic myeloid leukemia, which improved the hematological indicators and clinical symptoms of patients. It has been proved that the inorganic compound arsenic trioxide can treat relapsed or refractory acute promyelocytic leukemia (APL), and recent preliminary data show that arsenic trioxide also has an effect on other cancers, so the study of arsenic trioxide as an anticancer ...
