Combination of analogs or derivatives of dianhydrogalactitol with platinum-containing antineoplastic agents to treat cancer

The use of dianhydrogalactitol provides a novel therapeutic modality for the treatment of non-small-cell lung carcinoma (NSCLC) and ovarian cancer, as well as other types of malignancy, including brain metastases of NSCLC. Dianhydrogalactitol acts as an alkylating agent on DNA that creates N7 methylation. Dianhydrogalactitol is effective in suppressing the growth of cancer stem cells and is activeagainst tumors that are refractory to temozolomide, cisplatin, and tyrosine kinase inhibitors; the drug acts independently of the MGMT repair mechanism. Dianhydrogalactitol can be used together withother anti-neoplastic agents and can possess additive or super-additive effects.

Combined medication mode for synergistically treating human brain glioma

The invention discloses a combined medication mode for synergistically treating human brain glioma, and belongs to the technical field of pharmacology. Through the combined use of two tumor cell inhibiting drugs, i.e. Perphenazine and temozolomide are combined to treat human brain glioma cells, a model is established to quantify a combined effect. By selecting different concentrations of a stem cell inhibitor perphenazine and a human brain glioma chemotherapeutic drug temozolomide, the proliferation of U87 cells and U251 cells is inhibited by combined administration, the combination index (CI) value obtained by model quantification after the two drugs are combined for use reaches 0.3299 + / -0.002, and a strong synergistic effect is achieved; through colony formation experiment detection, the cell clone formation rate of a drug combination group is obviously lower than that of a control group and a single drug administration group, and a novel and creative drug administration mode can provide a novel drug administration strategy for treating human brain glioma.
