Embodiment 1

[0065] Agonist activity of pentacyclic triterpene saponins on AMPK in Huh-7 cells

[0066] The agonistic activity of compounds on AMPK in Huh-7 cells was detected by Western Blot method.

[0067] Cell culture conditions: Huh-7 cells: DMEM complete medium (containing 10% fetal bovine serum and 1% streptomycin / penicillin) in 5% CO 2 cultured in a 37°C incubator.

[0068]Antibodies: anti-AMPK (CST, 2532S); anti-pAMPK (CST, 2535S).

[0069] Western Blot experiment: To detect the effect of the compound on the phosphorylation level of AMPK in Huh-7 cells: cells with a proportion of living cells above 90% were used for the experiment. In 12-well plates, Huh-7 cells were plated at 250,000 per well, placed in 5% CO 2 After 12 hours, the original medium was discarded, and the complete medium containing pentacyclic triterpenoid saponins was added. The final concentration of the tested pentacyclic triterpene saponins was set to 10 μM, and the administration time was 12 hours. AICAR (...

Embodiment 2

[0075] Effects of pentacyclic triterpene saponins on the downstream signaling pathway of AMPK in Huh-7 cells

[0076] Western Blot method was used to detect the effect of compounds on the downstream signaling pathway of AMPK in Huh-7 cells.

[0077] Cell culture conditions: Huh-7 cells: DMEM complete medium (containing 10% fetal bovine serum and 1% streptomycin / penicillin) in 5% CO 2 cultured in a 37°C incubator.

[0078] Antibodies: anti-ACC(CST,3676S); anti-pACC(CST,11818S); anti-mTOR(CST,2983S); anti-pmTOR(CST,5536S); anti-PGC1α(Abcam,ab54481); (Abcam, ab76228).

[0079] Western Blot experiment: detecting the effect of the compound on the downstream signaling pathway of AMPK in Huh-7 cells:

[0080] Cells with a live cell ratio above 90% were used for experiments. In 12-well plates, Huh-7 cells were plated at 250,000 per well, placed in 5% CO 2 After 12 hours, the original medium was discarded, and the complete medium containing pentacyclic triterpenoid saponins was ad...

Embodiment 3

[0083] Protective effect of ginsenoside Ro (compound of formula (I)) on high-fat diet (HFD)-induced NASH rat model.

[0084] Animals: 32 male SD rats, SPF grade, 6 weeks old, weighing 220 g, purchased from Beijing Weitong Lihua. All animals were maintained on a 12-h alternating circadian rhythm with free access to food and drink.

[0085] Instruments: animal weight scales; slicers; automatic biochemical analyzers; inverted microscopes

[0086] Reagents: Ginsenoside Ro(I) was purchased from Shanghai Boka Chemical Technology Co., Ltd.; obeticholic acid (OCA) was purchased from Jiangsu Vicare Pharmaceutical Technology Co., Ltd.; high-fat feed was purchased from Research Diets (D12492, 60kcal%); Standard feed was purchased from Research Diets (D12450B, 10 kcal%).

[0087] experiment procedure:

[0088] 1. Animal grouping and modeling

[0089] Rats were randomly divided into 4 groups according to body weight: control group (CHOW), high-fat diet model group (HFD), positive drug ...

Abstract

The present invention discloses an application of pentacyclic triterpenoid saponin represented by formulas (I) to (XIII) for the preparation of a medicine for preventing or treating AMPK-mediated diseases including fatty liver disease, inflammatory bowel disease, respiratory disease, diabetic complications and polycystic kidney disease. The compounds of formula (I) to (XIII) are especially usefulfor nonalcoholic simple fatty liver, nonalcoholic steatohepatitis, non-alcoholic steatohepatitis-induced cirrhosis, ulcerative colitis, Crohn's disease, chronic obstructive Pulmonary diseases, asthma,idiopathic pulmonary fibrosis, cystic fibrosis, allergic rhinitis, diabetic nephropathy, diabetic cardiomyopathy, diabetic ulcers, and autosomal dominant polycystic kidney disease. A pharmaceutical composition for preventing and treating the AMPK-mediated diseases of the present invention comprises a therapeutically effective amount of the compounds of the formula (I) to (XIII) or a pharmaceutically acceptable salt or a solvate thereof as an active ingredient and a pharmaceutically acceptable excipient.

Description

technical field [0001] The present invention belongs to the field of medicine, and specifically relates to the use of pentacyclic triterpene saponins in the preparation of medicines for preventing or treating AMPK-mediated diseases and a pharmaceutical composition.
