Problems solved by technology

At present, there are many anti-influenza virus drugs in clinical use, but most of them are highly toxic, easily damage host cells and easily lead to the emergence of drug-resistant strains
Currently, ribavirin has the best therapeutic effect, but it also has certain side effects. A small number of patients have symptoms such as dry mouth, soft or loose stools, and leukopenia when taking oral or intravenous injection. Animal experiments have carcinogenic effects. disabled

Abstract

The invention relates to an application of anthraquinones compound in preventing diseases infected by influenza virus. The median poison concentration TC50 of anthraquinones compound for cell MDCK is 226.1 ug/ml, the comparison is 351.3 ug/ml; the median effective concentration LC50 for influenza virus is122.4 ug/ml, the comparison is 62.7 ug/ml; and the treating index is 1.9. It is proved that the inhibiting rate for influenza virus is increased with increased drug concentration. The side effect of nthraquinones compound is smaller than that of ribavirin, the process is simple and it can be prepared into various dosage forms.

Description

(1) Technical field: [0001] The present invention relates to the application of rhubarb anthraquinone compounds, specifically the application of rhubarb anthraquinone compounds in the prevention and treatment of influenza virus infectious diseases (two) background technology: [0002] Influenza is an acute viral respiratory infectious disease caused by influenza virus, characterized by high incidence, widespread prevalence and rapid spread. At present, there are many anti-influenza virus drugs in clinical use, but most of them are highly toxic, easily damage host cells and easily lead to the emergence of drug-resistant strains. Currently, ribavirin has the best therapeutic effect, but it also has certain side effects. A small number of patients have symptoms such as dry mouth, soft or loose stools, and leukopenia when taking oral or intravenous injection. Animal experiments have carcinogenic effects. disabled. (3) Contents of the invention: [0003] The purpose of the pr...
