Abstract

The invention provides application of rutoside in preparation of an osteosarcoma treating drug. Through experimental means, it is found that rutoside not only has the pharmacological actions such as the oxidation resistance and lipid metabolism regulation which are disclosed in the prior art, but also has the outstanding osteosarcoma inhibiting effect. In-vivo experiments find that proliferation of entity osteosarcoma can be significantly inhibited after rutoside is taken orally or injected, in-vitro experiments find that the growth speed of osteosarcoma cells is obviously decreased in a cell culture system containing rutoside, and therefore the pharmacological property of rutoside on inhibiting the osteosarcoma can be verified. In addition, it is found that rutoside is wide in treatment range and has the exact inhibiting effect on the fibroblast type, the sclerotic type, and bone limphosarcoma and the like. On the basis of the novel pharmacological property of rutoside, the novel application of preparing the osteosarcoma treating drug from rutoside is determined, the treatment effect of the drug is exact, the osteosarcoma inhibiting effect is obvious, and therefore the outstanding popularization prospect is achieved.

Description

technical field [0001] The invention relates to the technical field of drugs for treating orthopedic diseases, in particular to the application of rutin for preparing drugs for treating osteosarcoma. Background technique [0002] Osteosarcoma is the most common type of malignant bone tumor, which develops from mesenchymal cell lines. The rapid growth of the tumor is due to the direct or indirect formation of tumor bone-like tissue and bone tissue through the cartilage stage. Under the action of external factors (such as viruses), the load-bearing bones of the lower limbs cause cell mutations, which may be related to the formation of osteosarcoma. The typical osteosarcoma originates in the bone, and another completely different type is the osteosarcoma juxtaposed with the bone cortex, which originates from the periosteum and nearby connective tissue. The latter is less common and has a better prognosis. [0003] Osteosarcoma is still a disease with high mortality from malig...
