Technical Field

The invention belongs to the technical field of medicines, and particularly relates to a micromolecule compound and application thereof in preparing an anti-tumor metastasis medicine.

Background

In addition to infiltrating and growing at the primary site and affecting adjacent organs, malignant tumors can also spread to other parts of the body by means of lymphatic vessels, blood vessels, etc., and this process is called tumor metastasis. In recent years, the prevalence and mortality of malignant tumors have been increasing year by year. Moreover, the malignant tumor is easy to metastasize, so that clinical medication, surgical treatment and the like are very difficult, and more than 90% of malignant tumor patients die of tumor metastasis. At the same time, tumor metastasis can occur in an "early" state where the primary tumor is still small. More and more evidence shows that: in the state where the primary tumor is still microscopic, distant dissemination of tumor cells has already occurred. Therefore, prevention of tumor metastasis becomes a key point for the treatment of malignant tumors.

Currently, over 200 over anticancer drugs have been approved by FDA, and cytotoxic drugs remain the basic and major approaches to anti-tumor, but there is still a lack of drugs in clinical use that can achieve the goal of high efficacy and low toxicity, with less inhibition of tumor metastasis. Cytotoxic drugs often injure normal cells while killing tumor cells, and cannot effectively inhibit tumor cell metastasis, so that clinical common tumor primary lesions are relieved, but a plurality of metastasis lesions appear, and finally the disease condition is worsened. Therefore, for modern tumor treatment, it is very important to provide a drug capable of inhibiting tumor cell metastasis.
