Method for treatment of liver cancer and inhibition of metastasis with CXC-chemokine-receptor 4-targeted nanoparticle

摘要

Provided is a method for treatment of liver cancer and inhibition of metastasis with CXCR4-targeted nanoparticle. A CXCR4 antagonist is used as a targeting molecule to modify a lipid carrier for the formation of nanoparticle carrying an anti-angiogenesis drug or an anti-angiogenic nucleotide. Such nanoparticle can enhance the accumulation and uptake of the drug and nucleotide in liver cancer cells as well as sensitize the liver cancer cells to treatment of said drug and nucleotide, providing a synergistic suppression of angiogenesis and tumor progression. Furthermore, the CXCR4-targeted nanoparticle can effectively inhibit metastasis of liver cancer. The pharmaceutical composition is an injectable composition; hence, is suitable for clinical application for the treatment of liver cancer.

主权项

1. A method for treatment of liver cancer and inhibition of metastasis of liver cancer, comprising administrating to a subject in need a therapeutically effective amount of a pharmaceutical composition comprising a CXC-chemokine-receptor 4(CXCR4)-targeted nanoparticle, the nanoparticle comprises:
a core comprising an anti-angiogenesis drug or a nucleotide having an anti-angiogenic effect; a lipid carrier encapsulating the core; and a CXCR4-targeted molecule attached to the surface of the lipid carrier, wherein the CXCR4-targeted molecule specifically delivers the nanoparticle to a hepatocellular carcinoma and sensitizes the hepatocellular carcinoma to the anti-angiogenesis drug or nucleotide having an anti-angiogenic effect to provide a synergistic effect of the anti-angiogenesis drug or the nucleotide having the anti-angiogenic effect to the hepatocellular carcinoma.
