Description

Oxaliplatin-coupled prodrug, preparation method and application thereof
Technical Field
The invention belongs to the technical field of pharmaceutical chemicals, and particularly relates to an oxaliplatin coupled prodrug, and a preparation method and application thereof.
Background
Chemotherapy is one of the main means of current cancer treatment, wherein (bivalent) platinum drugs have the characteristics of good anti-cancer effect, wide indication and the like, and Cisplatin (cissplatin) and Oxaliplatin (Oxaliplatin) are mainly used for treating various malignant tumors in clinic at present. However, oxaliplatin is liable to cause severe gastrointestinal reactions, nephrotoxicity and bone marrow toxicity. Meanwhile, oxaliplatin easily causes acquired drug resistance, the curative effect is seriously reduced, and the clinical use effect of oxaliplatin is limited. A covalent coupling strategy is utilized to construct a coupled prodrug of oxaliplatin and active molecules, so that the use dosage of the oxaliplatin is expected to be reduced, and the toxic and side effects are reduced. Meanwhile, drug resistance is avoided, and the curative effect is improved.
According to the report of the literature, oxaliplatin can induce immune cell death and activate the immune response of the organism. However, the stimulation of chemotherapeutic drugs such as oxaliplatin and the like can cause the over-activation of indoleamine 2, 3-dioxygenase 1(IDO-1) in tumor cells. Indoleamine 2, 3-dioxygenase 1(IDO-1) degrades tryptophan (Trp) to produce kynurenine (Kyn). Tryptophan is a nutrient for cytotoxic T lymphocytes and kynurenine induces T cell apoptosis, so high expression of IDO-1 inhibits differentiation and proliferation, resulting in an immunosuppressive microenvironment. High expression of IDO-1 is associated with poor clinical prognosis in a variety of malignant patients. IDO-1 has become one of the important targets for tumor immunotherapy. NLG919 inhibits tumor cell immune evasion by inhibiting IDO-1 activity. According to the invention, the tetravalent oxaliplatin covalently modified by NLG919 is synthesized, the compound can reduce and release oxaliplatin and NLG919 in cells, and the chemotherapy and immunotherapy combined treatment is realized, so that the invention has good innovation.
