Description

Application of vinblastine derivative in preparation of medicine for treating osteosarcoma and/or soft tissue sarcoma
Technical Field
The invention belongs to the field of medicines, and particularly relates to application of vinblastine derivatives in preparation of medicines for treating osteosarcoma and/or soft tissue sarcoma.
Background
Osteosarcoma and soft tissue sarcoma are malignant tumors originating from mesenchymal tissues, and have a very high rate of metastasis and recurrence. Surgery and chemotherapy are the primary treatment for osteosarcoma and soft tissue sarcoma. Cisplatin, cyclophosphamide, doxorubicin and methotrexate are first-line agents of osteosarcoma chemotherapy, while doxorubicin and ifosfamide constitute the two major cornerstones of soft tissue sarcoma chemotherapy. The survival rate of osteosarcoma patients can be improved to 60-70% within 5 years by chemotherapy, and the survival rate of soft tissue sarcoma patients is still lower than 10% by chemotherapy. Osteosarcoma and soft tissue sarcoma metastasize to the lung mainly by hematogenous metastases, with a survival rate of less than 20% in 5 years for patients with lung metastases. Large doses of chemotherapeutic drugs can cause nausea, vomiting, bone marrow suppression, cardiotoxicity and other adverse reactions in patients, resulting in poor patient compliance and poor quality of life. Therefore, the development of low-toxicity and high-efficiency targeted therapeutic drugs has important significance in the treatment of osteosarcoma and soft tissue sarcoma.
The enzyme activated prodrug can improve the targeting property of the parent drug to enzyme expression cells and reduce the toxic and side effects of the parent drug to organisms. The specific principle is as follows: the active group of the parent drug is blocked by the polypeptide to form an inactive form of prodrug, the prodrug is a hydrolysis substrate of a specific enzyme, and when the prodrug meets a specific enzyme highly expressed by cells, the prodrug is hydrolyzed to release the active parent drug, so that the cells expressing the enzyme are killed. Fibroblast activation protein alpha (FAP alpha) is a type ii serine protease belonging to one of the members of the dipeptidyl peptidase family, having dipeptidase hydrolysis activity and uniquely having restriction endonuclease activity, and specifically hydrolyzing a substrate coupled with N-terminal benzoyl (Z) -blocked Gly-Pro (Z-GP). The research shows that FAP alpha is not expressed or is low expressed in normal bone and soft tissue, but is continuously high expressed on bone and soft tissue tumor cells (Dohi O et al. histopathology.2009,55(4): 432-40); tumor cells of osteosarcoma patients highly express FAP alpha and have positive correlation with prognosis and metastasis (Yuan et al.J Surg Oncol.2013,108(3): 157-62; Zhang et al.Clin Exp Med.2020,20(1): 121-30). The research shows that FAP alpha can be used as an effective target for treating osteosarcoma and soft tissue sarcoma, and the FAP alpha enzyme activated prodrug is expected to be a good design strategy for treating osteosarcoma and soft tissue sarcoma.
The vinblastine compound is a known bisindole alkaloid separated from Catharanthus roseus of Apocynaceae and its derivatives, including vinblastine, vinorelbine, vinflunine, vincristine, vinblastine or vindoline. The applicant of river-south university and the published Chinese invention patent application (CN201310138241.8) disclose vinblastine derivatives of vinblastine compounds subjected to hydrazinolysis and dipeptide derivatization and application thereof in preparation of antitumor drugs. The entire contents of this patent application are incorporated into this application by reference.
Pharmacological studies have shown that vinblastine and its analogues or derivatives belong to cytotoxic drugs, mainly inhibiting the polymerization of tubulin, thus preventing the formation of spindle microtubules, and arresting nuclear division in the metaphase (Martino E, et al bioorg Med Chem lett.2018,28(17): 2816-26). Since the 70's of the 20 th century, vinblastine and its derivatives were used clinically alone or in combination with first-line osteosarcoma therapeutics, but the therapeutic effects were not satisfactory (Claudia MH et al Pharmacogenomics.2016,17(18): 2097-114; Veronique MC et al Eur J cancer.2012,48(15): 2409-16). In addition, vinblastine and its derivatives have adverse reactions such as bone marrow suppression, and limit its long-term and large-dose application. In conclusion, there is a great clinical need for effective therapeutic agents for osteosarcoma and soft tissue sarcoma.
