A kind of trimethylammonium xanthone-4-acetate medical composition and its use for the treatment of cancer
Technical field
The present invention relates to a kind of drug regimen, is a kind of trimethylammonium xanthone-4-acetate medical composition and its use for the treatment of cancer specifically.
Background technology
Cancer is a big class disease of serious threat human health.Operation, chemicotherapy and cancer drug therapy are three main method for the treatment of cancer at present.Traditional medicine that acts on tumour cell is a cytotoxic drug, but its major defect is to the solid tumor weak curative effect, and poor selectivity when the poisoning tumour cell, has also been killed normal cell, erious adverse reaction, and easily produce resistance.1971, professor Folkman of medical college of Harvard University proposed famous " tumour hungry to death " theory, promptly by the nutrition supply of the tumor neovasculature generation cut-out of blocking-up tumour, reached the purpose of inhibition and treatment tumour.Act on tumor neovasculature medicine and divide two classes: a kind of be angiogenesis inhibitor (tumor angiogenesi inhibitor, TAI), another kind be destroy tumor neovasculature medicine (vascular targeting agents, VTA).In binding mode and treatment application facet, TAI requires to continue some months or medication in several years, and VTA is an intermittent use, and it can directly destroy existing tumor vessel, causes cancer cell death.Small molecules VTA can reduce the tumor vessel volume of blood flow fast, the necrosis on a large scale of the rapid minimizing of blood flow and tumour, and therapeutic domain is wide, and the characteristics that persister is difficult for producing make it receive increasing concern.But only in inside tumor powerful destruction is arranged, and the cell of borderline tumor is not had restraining effect, such exercising result makes it single not obvious with tumor killing effect.Borderline tumor blood is abundant, and traditional radiotherapy and chemotherapy medicine is relatively more responsive to this part cell, so VTA class medicine will be united use with traditional radiotherapy and chemotherapy medicine.DMXAA is the VTA class medicine that can cause the tumor vessel damage fast and selectively.At present, it is clinical that DMXAA has entered the III phase.
The compound trimethylammonium xanthone that the present invention relates to-4-acetate (TMXAA) is the compound similar to the DMXAA chemical structure.Specifically be included as: a) 2,5,6-trimethylammonium xanthone-4-acetate; B) 5,6,7-trimethylammonium xanthone-4-acetate; C) 5,6,8-trimethylammonium xanthone-4-acetate, the chemical structural formula of these three compounds is as follows:
In Chinese patent 200710053403.2, the preparation of TMXAA and the purposes in anticancer there is detailed description.(TMXAA) is the same with DMXAA for trimethylammonium xanthone-4-acetate, also is the tumor neovasculature VTA class of a kind of destruction medicine.Show that in animal experiment its antitumour activity is better than carrying out at present clinical DMXAA of III phase.
Trimethylammonium xanthone-4-acetate (TMXAA) influences tumor vascular endothelial cell and the inducing cell factor is optionally blocked tumor vessel by direct, and the result has blocked the blood confession of tumour, causes neoplasm necrosis.
But animal experiment is found, though TMXAA demonstrates the anti-angiogenic active tumor blood flow effect that suppresses for a long time that produces, can the necrosis of induced tumor big area middle section, yet the normal adjacent tissue place still can observe the tumour cell of survival around tumour, and acceptable explanation is that they have accepted supply from the healthy tissues blood vessel to this part tumor survival, and these remaining tumor tissues can be used as the source of tumor regrowth.Therefore, single effect with TMXAA treatment tumour has been still circumscribed.
We find unexpectedly, are used in combination with TMXAA and pharmacy acceptable salt thereof or ester and other drug, can play to strengthen the anti-tumor synergetic result of treatment.
Summary of the invention
The object of the invention is exactly the defective at existing cancer therapy drug, and a kind of trimethylammonium xanthone-4-acetate pharmaceutical composition for the treatment of cancer is provided, and it has strengthened the anti-tumor activity of medicine, and the synergy by several drugs has good effect to the treatment cancer.
