Embodiment 1

[0015] IC50 determination experiment

[0016] Experimental procedure: OCM1 and OM431 cells were seeded in a 384-well plate, 2500 cells per well, 50ul culture medium, 10 concentration gradients were added to Mithramycin, 37°C, 5% CO 2 After incubating for 72 hours, add cell-title glo reagent and incubate at room temperature for 10 minutes, test on the computer, and calculate IC50 according to the measured experimental results, that is, the median lethal dose. Experimental results such as figure 1 shown.

Embodiment 2

[0018] Plate cloning experiments

[0019] Experimental procedure: OCM1 and OM431 cells were seeded in 6-well plates, 1000 cells per well, 2ml of culture medium, 10uM concentration of Mithramycin was added, 37°C, 5% CO 2 After culturing for 7 days, stained with crystal violet, the experimental results are as follows: figure 2 shown. Such as figure 2 Mithramycin can effectively inhibit the proliferation of uveal melanoma cells.

[0020] The present invention finds for the first time that the application of mithermycin in the preparation of drugs for uveal melanoma can significantly inhibit the growth and migration of uveal melanoma cells, and promote cell apoptosis, which provides a new therapeutic drug that can improve Treatment effectiveness, prolong life of patients, improve quality of life. Unprecedented to open up a new field.

Abstract

An application of a transcription factor Spl specific inhibitor in preparation of medicines treating uveal melanoma is disclosed. The molecular formula of the inhibitor is C<52>H<76>O<24>, and the molecular structural formula of the inhibitor is shown as a formula I shown in the description. The application of mithramycin in preparation of medicines treating uveal melanoma is disclosed for the first time. The mithramycin can significantly inhibit growth and migration of uveal melanoma cells and can promote cell apoptosis. A novel treatment medicine is provided and can improve treatment effectiveness, prolong lifetime of patients and improve life quality. An unprecedented novel field is opened up.

Description

technical field [0001] The invention relates to the field of medicine, in particular to the application of a specific inhibitor of transcription factor Sp1 in the preparation of a drug for treating uveal melanoma. Background technique [0002] Uveal melanoma (UM) is a special type of melanoma that originates from the uveal layer of the eye. UM is the most common primary intraocular malignancy in adults, the majority of which are choroidal melanomas. UM usually occurs unilaterally and unifocally, but rare cases of bilateral or multifocal tumors occur in the same eye. UM can not only cause vision loss, but also seriously threaten the life of patients. UM mainly metastasizes through blood, and half of the patients can develop distant metastases, mainly to the liver. Once the diagnosis is established, it is usually fatal within 1 year, because there is currently no effective clinical treatment. Even if the eyeball of the affected eye is removed before definite metastasis occ...
