Embodiment 1

[0067] Example 1 Mogroside IIIe improves bleomycin-induced mouse lung fibrosis

[0068] The above-mentioned mogroside IIIe was selected for the following in vivo pharmacodynamic studies. Intratracheal injection of bleomycin to induce pulmonary fibrosis in mice is a method commonly used in the world, and it is similar to human pulmonary interstitial fibrosis.

[0069] 1.1 Experimental method

[0070] ICR mice, male, weighing 25-30g, 100, provided by Yangzhou Comparative Medicine Center.

[0071] 20 mice were used as blank control group ( figure 1 The control group in), the other 80 are used for making models, all the above-mentioned mice are anesthetized by intraperitoneal injection of 4% chloral hydrate, the injection volume is 10ml / kg, after the mice are anesthetized, the mice are fixed and the necks of the mice are disinfected Cut the mouse neck skin longitudinally with scissors to expose the trachea; inject a syringe into the trachea, inject normal saline into the mice i...

Embodiment 2

[0094] Example 2 Mogroside IVe improves mouse lung fibrosis induced by bleomycin

[0095] The above-mentioned mogroside IVe (formula IV) was selected for the following in vivo pharmacodynamic studies.

[0096] 2.1 Experimental method

[0097] ICR mice, male, weighing 25-30g, 100, provided by Yangzhou Comparative Medicine Center.

[0098] 20 mice were used as the blank control group, and the other 80 were used for modeling. All the above-mentioned mice were anesthetized by intraperitoneal injection of 4% chloral hydrate, and the injection volume was 10ml / kg. After the mice were anesthetized, the mice were fixed and sterilized Neck of the mouse: cut the skin of the neck of the mouse longitudinally with scissors, and bluntly tear the fascia and muscles longitudinally with tweezers to expose the trachea; inject a syringe into the trachea, inject normal saline into the mice in the blank control group, and inject normal saline into the other mice Bleomycin (5mg / kg); then the mouse...

Embodiment 3

[0115] Example 3 Mogrosanol improves bleomycin-induced mouse lung fibrosis

[0116] The above-mentioned mogrosvenol (formula IX) was selected for the following in vivo pharmacodynamic studies.

[0117] 3.1 Experimental method

[0118] ICR mice, male, weighing 25-30g, 100, provided by Yangzhou Comparative Medicine Center.

[0119] 20 mice were used as the blank control group, and the other 80 were used for modeling. All the above-mentioned mice were anesthetized by intraperitoneal injection of 4% chloral hydrate, and the injection volume was 10ml / kg. After the mice were anesthetized, the mice were fixed and sterilized Neck of the mouse: cut the skin of the neck of the mouse longitudinally with scissors, and bluntly tear the fascia and muscles longitudinally with tweezers to expose the trachea; inject a syringe into the trachea, inject normal saline into the mice in the blank control group, and inject normal saline into the other mice Bleomycin (5mg / kg); then the mouse board w...

According to the invention, the novel pharmaceutical application of the cucuribitane tetracyclic triterpenoids, namely the application of the cucuribitane tetracyclic triterpenoids in preparing the medicines and / or health-care products for preventing and / or treating the pulmonary fibrosis diseases, is provided.

Description

technical field [0001] The invention belongs to the technical field of prevention and treatment of pulmonary fibrosis, and relates to the application of a cucurbitane-type tetracyclic triterpenoid compound in the preparation of medicines and / or health care products for preventing and / or treating pulmonary fibrosis. Background technique [0002] Pulmonary fibrosis (PF) is a chronic interstitial lung disease characterized by the infiltration of inflammatory cells such as lymphocytes and macrophages in the pulmonary interstitium, the proliferation of fibroblasts, and the deposition of fibrous connective tissue in the pulmonary interstitium. . Pulmonary fibrosis is caused by various pathogenic factors inside and outside the lung, and is the result of a series of chronic lung injuries or the development of advanced diseases, which seriously endangers human health. The etiology of pulmonary fibrosis includes hereditary immune dysfunction, viral infection, drugs and chemicals, rad...
