Abstract

The invention provides a novel application of protocatechualdehyde as a drug and particularly relates to an application of protocatechualdehyde to pulmonary fibrosis prevention or treatment realized by inhibiting epithelial intercellular substance conversion and fibroblast proliferation and further inhibiting the occurrence and development of pulmonary fibrosis. According to the application, the dosage range of protocatechualdehyde is 20-2000mg and preferably 20-1000mg.

Description

technical field [0001] The present invention relates to protocatechualdehyde inhibiting the occurrence and development of pulmonary fibrosis so as to prevent or treat pulmonary fibrosis; specifically, it relates to protocatechualdehyde inhibiting pulmonary fibrosis by inhibiting epithelial-mesenchymal transition (EMT) and inhibiting abnormal activation of pulmonary fibroblasts. The occurrence and development of fibrosis can prevent or treat pulmonary fibrosis. Background technique: [0002] Idiopathic pulmonary fibrosis (IPF), also known as cryptogenic fibrosing alveolitis (CFA), is a chronic inflammatory interstitial disease. (usual interstitialpneumonia, UIP) is a characteristic pathological change with unknown etiology. The main manifestations are that the appearance of fibroblastic foci leads to the deposition of a large amount of extracellular matrix (ECM), the accumulation of collagen, and the destruction of alveolar structure, which eventually leads to the destructio...
