Abstract

The invention relates to disubstituted phenyl biguanide compounds and application containing the same to inducing malignant tumor cell for anoikis and inhibiting tumor growth and transfer. Proved by in vitro-in vivo experiments, the disubstituted phenyl biguanide compounds show the remarkable functions of inducing the malignant tumor cell for anoikis, starting caspase cascade and inhibiting tumor growth and transfer and also have the characteristics of high efficiency and low toxicity, so the disubstituted phenyl biguanide compounds as pharmaceutical compounds are expected to be applied to a plurality of malignant tumor medicaments for inhibiting the tumor growth, invasion and metastasis and treating human melanoma, neurospongioma, lung cancer, gastric cancer, prostate cancer, ovarian cancer and the like.

Description

technical field [0001] The invention belongs to the technical field of pharmacological experiment research, and relates to the application of a series of double-substituted phenylbiguanide compounds in causing anoikis of malignant tumor cells, more specifically, a double-substituted phenylbiguanide with anti-tumor activity Application of compound and pharmaceutical composition containing such compound in inhibiting tumor growth and metastasis and treating human melanoma, glioma, lung cancer, gastric cancer, prostate cancer, ovarian cancer and other malignant tumors with high expression of integrin αvβ3 . Background technique [0002] Integrin αvβ3 is composed of αv and β3 subunits, of which αv subunit (CD51) has 1018 amino acid residues and a molecular weight of 125 kD, and β3 subunit (CD61) has 762 amino acid residues and a molecular weight of 105 kD. It is an important adhesion molecule on the cell surface. On the one hand, it mediates the adhesion between cells and the e...
