< Experimental Example 1> Evaluation of anticancer activity against uterine cancer cells
In order to evaluate the anticancer activity of the macrospelide derivative according to the present invention, the following experiment was conducted using Macross Pelide A as a control group.
Specifically, cell survival experiments were performed using a luminescent cell viability assay kit. SKOV3 cells as a cervical cancer cell line were divided into 4 x 10 < 3 > cells in an opaque-partitioned 96-well microplate, and then treated with the conventional Macross Pelide A as the control group and the macrospelide derivative prepared in Example 1 , And cultured at 37 DEG C for 72 hours. It was also incubated at room temperature for 30 minutes for equilibration of microplates.
Next, 100 mL of the CellTiter-Glo® reagent was added to the medium containing 100 mL of cells, and the plate was mixed with a rotating agitator containing cell milling for 2 minutes. To stabilize the luminescent signal, the plate was incubated at room temperature for 10 minutes and the luminescence signal for each concentration of the compound of Example 1 and the control group was measured with a GENios reader and the results for cytotoxic activity are shown in Figure 1 .
1 is a graph showing the anticancer activity of SKOV3 (uterine cancer cells) of the compound of Example 1 and the control compound according to the present invention as a fluorescence emission rate.
As shown in FIG. 1, the macrospelide derivative according to the present invention has an anticancer effect on cancer cells. More specifically, the compounds prepared in Example 1 according to the present invention exhibited less fluorescent emission than the control compounds at the concentrations of 2, 6, 12, 25, 50, 100 and 200 μM, respectively, Respectively. In particular, at a concentration of 50 μM, it was found that the anti-cancer effect was twice as much as that of the control compound. At a concentration of 100 μM, the anti-cancer effect was remarkably superior to that of the control compound by 5 times. The amount of fluorescence emitted is close to zero, indicating that it has a complete anticancer effect.
Therefore, the macrospelide derivatives according to the present invention are excellent in anticancer effect against uterine cancer cells, and thus can be effectively used as a pharmaceutical composition for the prevention or treatment of cancer diseases such as endometrial cancer and cervical cancer.
