preparation example Construction
[0030] The present invention also provides a preparation method of the above-mentioned medicine, comprising the following steps: directly preparing the lung cancer into a pharmaceutical preparation for preventing and treating breast cancer, or compounding the lung cancer and other medicines for preventing and treating breast cancer to prepare into a compound pharmaceutical preparation, or the active ingredients of the pulmonary cough and a pharmaceutically acceptable carrier are prepared into a pharmaceutical preparation for preventing and treating breast cancer.
[0031] In the preparation method of the pharmaceutical preparation of the present invention, the contents that are not described in detail, such as auxiliary materials, how to prepare, etc., are all conventional choices in the art.
Embodiment 1
[0034] MCF-7 cells, MDA-MB-231 cells, MDA-MB-468 cells, and 4T1 cells were collected in log phase, according to 6 × 10 3 The density of cells / well was inoculated in 96-well plates, and cultured overnight. After the cells adhered to the wall, sample solutions of different concentrations (lung Physiological saline solution of the active ingredient of Like Capsule (drug after removing the capsule shell), Feilike Capsule was produced by Guizhou Jianxing Pharmaceutical Co., Ltd.), and normal saline was used as the control group. After 72 hours of drug action, 10 μl of MTT with a concentration of 5 mg / ml was added to each well, incubated at 37°C for 4 hours, the supernatant was discarded, and 160 μl of DMSO was added to each well to dissolve. After the blue-purple crystal formazan was completely dissolved, the absorbance value OD ( 490nm).
[0035] Calculation method of inhibition rate: inhibition rate=(OD value of control group-OD value of treatment group) / OD value of control grou...
Embodiment 2
[0038] MDA-MB-231 cells were pressed 4 × 10 5 The amount of cells / well was inoculated in a 60mm circular petri dish for culture. After the cells adhered to the wall, sample solutions of different concentrations (0.25mg / ml, 0.5mg / ml, 1mg / ml, 2mg / ml) were added (lung Physiological saline solution of the active ingredient of Like Capsule (drug after removing the capsule shell), Feilike Capsule was manufactured by Guizhou Jianxing Pharmaceutical Co., Ltd., was used for 24h, and normal saline was used as the control group. The morphological changes of cells were observed under an inverted microscope.
[0039] The result is as figure 1 As shown, the number of cells decreased significantly with increasing drug concentration. The cell morphology changed, especially at high concentration, the cell shape changed from long spindle to round, and the cells were swollen.
