Abstract

The invention relates to a novel medicine application of a parthenolide medicine in preparing a medicine for treating rhabdomyosarcoma, wherein the parthenolide is gemmarane type sesquiterpene lactone extracted and separated from plants such as feverfew, and has biological activities of anti-inflammation, antibiosis, tumor resistance and the like.

Description

Application of parthenolide medicine in preparation of novel medicine for treating rhabdomyosarcoma
Technical Field
The invention relates to the technical field of medicines, in particular to application of a parthenolide medicine in preparation of a novel medicine for treating rhabdomyosarcoma.
Background
Rhabdomyosarcoma (RMS) originates in rhabdomyocytes or mesenchymal cells differentiated to rhabdomyocytes, occurs in about 6 per million worldwide each year, is the most common soft tissue sarcoma in children, and is a very important means in RMS treatment besides extensive excision of R0 cut edges as far as possible. Although the survival of children patients has improved to some extent in the past thirty years, the improvement of treatment quality and the treatment of recurrent RMS still remain a challenge to be solved. With the development of high-throughput sequencing and whole genome sequencing technologies, clues are provided for molecular biological mechanisms affecting RMS and potential targeted molecular therapies, but the specific pathogenesis of RMS is still not fully understood; although targeted drug therapy is currently a focus of research on RMS therapy, few anti-tumor targeted drugs have entered clinical trials. There are several current genomic studies on RMS that show that immune checkpoint blockade and epigenetic modifications can provide more insight to recurrent RMS patients. In addition, serious long-term complications such as delayed development of children may occur in radiotherapy, so that a medicament capable of inhibiting the growth of RMS cells or causing apoptosis of the RMS cells in combination with traditional chemotherapeutic drugs is urgently needed clinically.
Parthenolide (PTL) (structural formula A) is the most representative compound in sesquiterpene compounds, is a germacrane type sesquiterpene lactone extracted and separated from plants such as feverfew, has obvious anti-tumor effect, is nontoxic to normal cells, shows broad-spectrum cytotoxic and apoptosis promoting effects on various tumor cells, and prompts the development prospect of the Parthenolide as an important tumor inhibiting drug. A plurality of researches prove that the PTL has various anti-tumor effects of blocking cell cycle, inhibiting epithelial mesenchymal transition, inhibiting tumor cell migration and invasion, inducing tumor cell apoptosis and autophagy, inhibiting tumor angiogenesis, reversing multidrug resistance and the like, but no report is provided about the application of the parthenolide drug in the preparation of the drug for treating rhabdomyosarcoma at present.
Figure BDA0003565677500000021
Generally, rhabdomyosarcoma is a highly malignant tumor, and the single treatment effect of rhabdomyosarcoma is poor, and needs comprehensive treatment and long-term follow-up of multiple disciplines such as surgery, chemotherapy, radiotherapy and the like, and the onset thereof can bring heavy economic burden to individuals, families and society of patients, so that finding an effective treatment means for rhabdomyosarcoma becomes one of the problems to be solved urgently in the field of tumor science.
Has the advantages that:
the invention discovers that the application of the parthenolide medicine in preparing the novel medicine for treating rhabdomyosarcoma has the cell proliferation inhibition rate of 97.34 percent and has huge potential application prospect in the treatment of rhabdomyosarcoma.
Disclosure of Invention
It is an object of the present invention to provide a novel pharmaceutical use of a parthenolide drug for the treatment of rhabdomyosarcoma, said method of use comprising administering a therapeutically effective amount of the parthenolide drug to the rhabdomyosarcoma cells (A204).
Further, the invention also relates to a pharmaceutical composition or a pharmaceutical preparation of parthenolide for treating the cancer of rhabdomyosarcoma.
The following examples illustrate the above invention, however, are not intended to limit the scope of the invention in any way. Other test models known to those skilled in the relevant art can also determine the benefits of the claimed invention.
The specific implementation mode is as follows:
the purpose of this experiment was to examine the in vitro cell proliferation inhibitory effect of parthenolide on human rhabdomyosarcoma RD cell line (a 204).
1. Experimental Material
Parthenolide drug was purchased from Nanjing spring and autumn biotechnology, Inc.; human rhabdomyosarcoma A204, purchased from ATCC, USA. Before the experiment, the cells frozen in liquid nitrogen were recovered by a conventional method, and cultured in suspension at 37 ℃ under 5% CO2The high-glucose DMEM medium (supplemented with main components including 10% fetal calf serum, 100U/mL penicillin, 100 mu g/mL streptomycin and 2mmol/L L-glutamine) in the constant-temperature cell culture box is subjected to liquid change and passage once every 2-3 days, and cells in a logarithmic growth phase are taken for experiment.
2. Experimental methods
Tumor cells in logarithmic growth phase are taken, digested by trypsin and resuspended to a cell density of 1.5X 105Cell suspension per mL. The cell suspension was seeded in 96-well culture plates at an inoculum size of 90. mu.L/well, and then 10. mu.L of drug solutions of different concentrations, each concentration being 3 wells, were added to each well. Meanwhile, the medium containing no cells (100. mu.L of medium per well) was set as a blank group, and the cells cultured without drug (10. mu.L of medium in addition to 90. mu.L of cell suspension per well) were set as a control group. After the addition, the 96-well plate was placed at 37 ℃ in 5% CO2The constant temperature cell culture box is used for continuously culturing for 48 hours. After the culture was completed, 10. mu.L of CCK8 reagent was added to each well, and after incubation for 4 hours, the OD450 value of each well was measured in an enzyme-linked immunosorbent assay (the measurement wavelength was 450nm, and the average value of 3 wells was taken), and the proliferation inhibition ratio was calculated according to the following formula:
the proliferation inhibition ratio (%) was [ 1- (OD drug group-OD blank)/(OD control group-OD blank) ] × 100%.
3. Results of the experiment
The results of this experiment are shown below.
Kind of drug Drug concentration Drug proliferation inhibition ratio (%)
Doxorubicin (Positive control) 20μM 68.06
Parthenolide 20μM 97.34
From the above table, it can be seen that, the effect of parthenolide on the in vitro cell proliferation of human rhabdomyosarcoma a204 is highly effective, the inhibition rate is as high as 97.34%, and the effect of parthenolide on the proliferation of human rhabdomyosarcoma a204 far exceeds the level of the positive control drug doxorubicin at the same concentration, thus showing that parthenolide has great potential for being developed into drugs for resisting human rhabdomyosarcoma.
In summary, the above experimental results suggest that the parthenolide drug disclosed in the present invention has great application prospect in treating rhabdomyosarcoma and provides more options for means of treating rhabdomyosarcoma in the field.
The embodiments described above represent preferred embodiments of the present invention. It will be apparent to those skilled in the art that various modifications, alterations, substitutions and the like can be made without departing from the spirit and principles of the invention, and these modifications, alterations, substitutions and equivalents should also be construed as falling within the scope of the invention.
