Abstract

The invention provides application of polyethylene glycol artesunate as shown in Formula (I) in preparation of an anti-pulmonary fibrosis medicine. The polyethylene glycol artesunate can obviously reduce the degree of pulmonary fibrosis, the pulmonary index, and the content of hydroxyproline and malondialdehyde in pulmonary tissues of a pulmonary fibrosis mouse caused by bleomycin, and improve the survival, the spleen index and the thymus index of the pulmonary fibrosis mouse. Moreover, under the equivalent dose, the polyethylene glycol artesunate and artesunate are significantly different. In addition, the polyethylene glycol artesunate is high in water solubility, high in bioavailability, long in half-life period and low in administration frequency.

Description

technical field [0001] The invention relates to the technical field of artesunate derivatives, in particular to the application of polyethylene glycol artesunate in the preparation of anti-pulmonary fibrosis drugs. Background technique [0002] Pulmonary fibrosis (PF) is a disease characterized by massive fibroblast aggregation, extracellular matrix (EMC) deposition, and destruction of alveolar structures caused by inflammatory lesions and injuries, and progressive dyspnea is the main Clinical symptoms, respiratory failure at the end stage is the main cause of death. The etiology of pulmonary fibrosis is complex and can be caused by dust, radiation, allergies, viruses, drugs, etc. As a result, many patients develop diffuse pulmonary fibrosis, which seriously affects survival time and quality of life. [0003] Currently, there is no effective treatment for pulmonary fibrosis. Traditional treatment drugs include glucocorticoids, which can inhibit the chemotaxis and aggregati...
