USE OF 3-(4-HYDROXYPHENYL)PROPIONIC ACID IN PREPARATION OF DRUGS FOR PREVENTING AND TREATING RESPIRATORY TRACT INFECTION

摘要

The present invention relates to new medicine application of p-hydroxyphenylpropio nic acid. Experiments prove that p-hydroxyphenylpropionic acid has a remarkable pharmacological effect in inhibiting respiratory tract infection, particularly inhibiting pulmonary edema, inflammatory cell infiltration and cell apoptosis in lung injury and delaying lung function degradation of mice. Therefore, the present invention discloses the application of p-hydroxyphenylpropionic acid to prepare a medicine for preventing and treating respiratory tract infection, particularly pneumonia, pulmonary edema or pulmonary epithelial and/or endothelial cell necrosis in lung injury for the first time.
