Embodiment 1

[0057] Example 1 Synergistic Combination of DMXAA and Pingyangmycin

[0058] Material:

[0059] Cell lines: human lung cancer A549 cells and liver cancer SMMC-7721 cells

[0060] Preparation of test drugs: DMXAA was dissolved with 5% sodium bicarbonate before use, and then made into the required concentration with RPMI1640 culture solution; Pingyangmycin (PYM) was dissolved with normal saline before use, and then made into the required concentration with RPMI1640 culture solution .

[0061] Cell culture:

[0062] Inoculate human lung cancer A549 cells and liver cancer SMMC-7721 cells into sterile culture flasks, add appropriate amount of RPMI1640 culture medium, and incubate at 37°C, 5% CO 2 cultured in an incubator with saturated humidity. The cells grow purely adherent and are passaged every 2-3 days. Digest with 3g / L trypsin for 1min during subculture, pipette with culture medium to make cell suspension, and inoculate according to the required concentration.

Abstract

The invention relates to a pharmaceutical composition, particularly to a pharmaceutical composition with antitumor activity. The pharmaceutical composition with antitumor activity comprises 5,6-dimethylxanthenone-4-acetic acid (DMXAA) or an pharmaceutically acceptable salt or ester thereof and one drug component selected from glycopeptide antibiotics, actinomycins, mitomycins, glucoside antibiotics, Colchicum alkaloid, elemenes, aromatic enzyme inhibitors, LH-RH receptor antagonists, animal antitumor drugs and somatostatin analogues. The synergic composition has better antitumor activity. More specifically, the invention provides an application of the composition in treating tumors.

Description

technical field [0001] The present invention relates to a pharmaceutical composition, in particular to a compound 5,6-dimethylxanthone-4-acetic acid (DMXAA) or a pharmaceutically acceptable salt or ester thereof and a compound selected from glycopeptide antibiotics, radioactive Mitomycins, mitomycins, glycoside antibiotics, colchicine alkaloids, elemenes, aromatase inhibitors, LH-RH receptor antagonists, animal antineoplastic agents, or somatostatin-like The synergistic combination of any one of the drugs of the drug has stronger antitumor activity. Background technique [0002] Tumor growth depends on the formation of the vascular network inside the tumor. Under the promotion of vascular endothelial growth factor released by cancer cells and related macrophages, a large number of new blood vessels are formed, cancer cells continue to proliferate, oxygen and glucose are consumed in large quantities, and acidic metabolites accumulate. Stimulate the formation of new blood ves...
