Abstract

The present invention relates to substituted aromatic radical biguanide compounds and the application of their medicine composition in preparing medicine for treating malignant tumors. The substituted aromatic radical biguanide compounds possess, extracorporeal and intracorporeal experiments shows, obvious tumor cell inhibiting effect and the features of high efficiency and low toxicity, so that the medicine compounds are expected to be applied in inhibiting tumor attack and metastasis, inhibiting angiogenesis, and treating human melanoma, glioma, lung cancer and other malignant tumors with high expression of integrin.

Description

technical field [0001] The present invention relates to a method for treating malignant tumors with a series of substituted aryl biguanide compounds, more specifically a substituted aryl biguanide compound with antitumor activity and a pharmaceutical composition containing a therapeutically effective amount of such compounds in Inhibition of tumor invasion and metastasis and angiogenesis, as well as the treatment of human melanoma, glioma, lung cancer, gastric cancer, prostate cancer, ovarian cancer and other malignant tumors with high expression of integrin αvβ3. Background technique [0002] Malignant tumors are a large class of diseases that seriously threaten human health. Their abnormal proliferation is controlled by abnormal information in cells and is closely related to the abnormal activity and inactivation of corresponding genes in tumor cells. Traditional anticancer drugs are mainly cytotoxic drugs, which rely on the differences in the kinetics of growth, repair, a...
