Abstract

The invention provides a composition containing imatinib or pharmaceutically acceptable salt of imatinib and plant polysaccharide, wherein the plant polysaccharide is selected from one of lentinan, polyporus polysaccharide and lagenaria siceraria polysaccharide. The animal experiment shows that the composition can generate a synergetic antitumor effect for liver cancer, stomach cancer and lung cancer models.

Description

technical field [0001] The invention relates to the technical field of medicine, in particular to a composition containing imatinib and plant polysaccharides. Background technique [0002] Imatinib (also known as STI-571, CGP57148B) is a phenylaminopyrimidine derivative with a chemical name of (4-[(4-methyl-1-piperazine)methyl]-N-[ 4-Methyl-3-{(4-(3-pyridine)2-pyrimidine)}amino]phenyl)aniline, its mesylate salt for medicinal purposes, its structural formula is shown below. [0003] [0004] Imatinib is a selective tyrosine kinase inhibitor, which inhibits its tyrosine kinase activity by competitively binding to the ATP-binding site on BCR-ABL kinase, blocking the kinase's autophosphorylation and Substrate phosphorylation level, thereby specifically inhibiting the proliferation of BCR-ABL positive cells and inducing their apoptosis. The FDA-approved indications for imatinib include hematological tumors such as chronic myeloid leukemia (CML) and solid tumors such as gastr...
