The chemical structural formula of For-Oxide and For-Methyl are as below, respectively.
It can be known from the data of Tables 1-2 that the compounds in the above embodiments of the invention have inhibitory activities on the tyrosine kinases of C-MET, KDR, etc.
1. Methods
(1) Culture cells: Culture tumor cells (such as human lung adenocarcinoma cells HCC78, human malignant glioma cells U87MG, human gastric cancer cells MKN-45, human umbilical vein endothelial cells HUVEC, human lung adenocarcinoma cells A549, etc.) in culture medium; culture conditions: 37° C., 5% CO2.
(2) Inoculate cells: Take the cells at the exponential growth phase and in good state, add an appropriate amount of pancreatin for cell dissociation, collect the cells for centrifugation, and discard the supernatant. Resuspend the cells with the culture solution containing serum, then cound and inoculate the cell suspensions in a 96-hole plate at 3000/hole, 90 μL/hole. Transfer the culture plate into a constant temperature CO2 incubator, and culture under the conditions of 37° C., 5% CO2 and saturated humidity for 24 h.
(3) Add the test compounds: 10 μL/hole, culture for 72 h, set 3 parallel holes for each group.
(4) Determine the results: After 72 h of action for the compounds, add 10 μL/hole CCK8, incubate in the incubator for an appropriate time, and measure the absorbance at 450 nm,
2. Experimental Results
The detection results of the detected compounds are summarized as shown in Tables 3-6:
It can be known from the data of Tables 3-6 that the compounds of the invention can effectively inhibit the proliferation of various cancer cells, such as human lung adenocarcinoma cells, human gastric cancer cells, human gastric colon cancer cells, human gastric ovarian cancer cells, human malignant glioma cells, etc. by inhibiting the activities of tyrosine kinases of C-MET, KDR, etc., and they are especially suitable for treating cancers.
