Description

Application of oxfendazole as anti-ovarian cancer drug
Technical Field
The invention belongs to the technical field of medicines, and particularly relates to application of oxfendazole as an anti-ovarian cancer medicine.
Background
Ovarian cancer is a common malignancy of the female reproductive system, and in recent years, the incidence and mortality of ovarian cancer have been on the rise. Worldwide, ovarian cancer has its prevalence at position 3 among female reproductive malignancies and a high mortality rate at position 2. At present, ovarian cancer is mainly treated by adopting a comprehensive treatment method of surgery and chemotherapy. As for chemotherapy, with the continuous development of modern medical research, chemotherapy drugs for treating ovarian cancer are continuously developed, and the chemotherapy drugs for clinically treating ovarian cancer mainly comprise paclitaxel, carboplatin, doxorubicin and the like. The application of the chemotherapy drug can obviously improve the survival rate of ovarian cancer patients. However, the treatment effect of the chemotherapeutic drugs is still unsatisfactory due to the limitations of problems such as non-response to chemotherapy, tolerance to chemotherapy, toxic and side effects and the like, and the 5-year survival rate of patients with advanced ovarian cancer is only 20% -30%. Therefore, the search for new drugs for treating ovarian cancer is very slow.
Oxfendazole (Oxfendazole) with the chemical name of 5-phenylsulfonyl-benzimidazole-2-methyl carbamate and the molecular formula of C15H13N3O3S, molecular weight is 315.35, and is a novel high-efficiency, broad-spectrum and low-toxicity benzimidazole carbamate anthelmintic. The oxfendazole can inhibit an electron transfer system of a worm mitochondrion and a phosphorylation reaction coupled with the electron transfer system, inhibit ATP synthesis, and block a glucose transport system, so that the function of a microtubule depending on the glucose transport system is inhibited, and finally, a killing effect is generated on worms. At present, no report on the ovarian cancer resistance of oxfendazole exists.

Preferably, the two medicaments according to the above further comprise a pharmaceutically acceptable carrier and/or excipient. The two medicines can be mixed with pharmaceutically acceptable carriers or excipients to prepare the composition.
Further, the excipient refers to diluents, binders, lubricants, disintegrants, solubilizing agents, stabilizers and the like which can be used in the pharmaceutical field, and some pharmaceutical bases. The carrier is a functional pharmaceutical adjuvant which can be obtained in the field of medicines, and comprises a surfactant, a suspending agent, an emulsifier and some novel pharmaceutical high polymer materials, such as cyclodextrin, chitosan, polylactic acid (PLA), polyglycolic acid polylactic acid copolymer (PLGA), hyaluronic acid and the like.
Preferably, according to the two medicaments, the dosage forms of the medicaments comprise tablets, capsules, granules, dropping pills, infusion solutions and injections.
Further, the above dosage forms refer to clinically usual dosage forms. Pharmaceutical formulations may be administered orally or parenterally (e.g., intravenously, subcutaneously, intraperitoneally, or topically) and, if certain drugs are unstable under gastric conditions, may be formulated as enteric coated tablets.
Compared with the prior art, the invention has the beneficial effects that:
the invention provides a new application of oxfendazole in resisting ovarian cancer. According to research, the oxfendazole can obviously inhibit the activity of ovarian cancer cells from different sources; and can inhibit the proliferation of ovarian cancer cells and induce the apoptosis of ovarian cancer cells; the oxfendazole is proved to have good ovarian cancer resistance effect, and is expected to be developed into a novel medicament for efficiently treating ovarian cancer, so that the novel application of the oxfendazole is explored, and a novel medicament and a novel approach are provided for treating the ovarian cancer.

Detailed Description
The following further describes the embodiments of the present invention. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features involved in the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
The experimental procedures in the following examples were carried out by conventional methods unless otherwise specified, and the test materials used in the following examples were commercially available by conventional methods unless otherwise specified.
Experimental example 1 inhibitory Effect of Oxfendazole on ovarian cancer cell viability
Ovarian cancer cells (a2780, OVCAR3, SKOV3, and KGN) in logarithmic growth phase purchased from beina bio were seeded in 96-well plates at 5000 cells per well in 200 μ L RPMI-1640 medium. Drug treatment group, control group and blank group were set separately. Wherein, the drug treatment group is a group (10 μ M, 25 μ M, 50 μ M, 100 μ M) containing oxfendazole with different concentrations, the control group only contains cells without drugs, and the blank group does not contain cells but only contains culture medium. Drug-treated group cells were treated with drug for 48h, 4h before the end of treatment, 20 μ L of CCK8 solution was added to each well and incubation was continued for 4 h. Then, reading an absorbance value at the wavelength of 450nm by using a full-wavelength multifunctional microplate reader, and calculating the cell activity according to the following formula by using the absorbance value:
cell viability ═ 100% (drug treatment OD-blank OD)/(control OD-blank OD). Wherein the cell viability is half inhibitory solubility (IC)50) Calculated using Graphpad software.
As shown in the results of fig. 1, oxfendazole inhibited ovarian cancer cell viability.
Experimental example 2 inhibitory Effect of Oxfendazole on proliferation potency of ovarian cancer cells
Ovarian cancer cells (a2780) in log phase were seeded in six-well plates at 500 cells per well in 200 μ L of medium. Cells were treated with different concentrations of oxfendazole (7.5 μ M and 10 μ M) for 7 days after the cells were fully adherent. The culture medium was changed every 3 days during the process. After treatment the cells were discarded from the medium, washed 2 times with PBS, fixed with ice bath methanol for 5min and stained with crystal violet.
As shown in the results of fig. 2, oxfendazole inhibited the proliferative capacity of ovarian cancer cells.
Experimental example 3 Induction of apoptosis in ovarian cancer cells by Oxfendazole
Ovarian cancer cells (A2780) in the logarithmic growth phase were treated with oxfendazole (5. mu.M and 10. mu.M) at different concentrations for 48h, then digested with EDTA-free trypsin for 2min to single cells, centrifuged at 2000rpm for 5min after digestion, and washed 2 times with PBS. Then, the apoptosis detection kit working solution (500. mu.L of apoptosis buffer, 5. mu.L of Annexin V-FITC dye and 5. mu.L of PI dye) purchased from Kyowa Kai Biotechnology Co., Ltd is added to the cells, and the cells are scattered, mixed uniformly and placed in the dark for reaction for 15 min. The apoptosis rate was measured using a BD FACSCAnto II flow cytometer. Wherein, cells which are Annexin V-FITC single positive and Annexin V-FITC/PI double positive are apoptosis cells.
As shown in the results of fig. 3, oxfendazole induced apoptosis in ovarian cancer cells.
The embodiments of the present invention have been described in detail, but the present invention is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, and the scope of protection is still within the scope of the invention.
