The invention relates to the field of pharmaceutical chemistry and medicine, and specifically to a class of pentacyclic triterpenoid glycoside compound, preparation method therefor, and the use thereof in treating metabolic diseases and anti-virus, in particular to the use in the preparation of medicine for treating diabetes, influenza, pneumonia induced by coronavirus and other diseases.
Diabetes Mellitus (DM) is a chronic, systemic and metabolic disease caused by the long-term joint action of genetic factors and environmental factors. It is characterized by an increase in plasma glucose levels. It is a disease that affects normal physiological activities due to the metabolic disorder of sugar, fat and protein caused by insulin secretion insufficiency or dysfunction of insulin (insulin resistance). The complications of diabetes can be classified into acute complications and chronic complications. Among them, acute complications include diabetes ketoacidosis, diabetes hyperosmolar coma, various acute infections and lactic acidosis, etc. In addition, hypoglycemia during the treatment of diabetes is also one of the most common acute complications. Chronic complications include diabetes ophthalmopathy, diabetes nephropathy, diabetes psychosis, diabetes cardio cerebral limb macroangiopathy, diabetes foot and skin lesions, etc. The main clinical manifestations of diabetes are polydipsia, polyuria, polyphagia and weight loss.
Diabetes is classified into insulin-dependent diabetes mellitus (IDDM, or type I diabetes) and non insulin-dependent diabetes mellitus, which are the most common, accounting for more than 90% of diabetes patients. The exact etiology and pathogenesis of type I diabetes are still not very clear. The etiology is jointly involved by genetic and environmental factors, mainly due to the damage of pancreatic islet b cells in the body, which leads to the inability to produce insulin in the body. Patients need insulin injection every day to control the insulin level in their blood. Type II diabetes is a kind of metabolic syndrome due to inability to control the blood glucose level in the body. Its main characteristics are hyperglycemia, insulin resistance and insulin secretion deficiency. The main etiology of type II diabetes is insulin resistance, which makes the body unable to use insulin effectively, or the reduction of insulin secretion make the insulin level unable meet the need of body. Because the patients with this type of diabetes can secrete insulin, they generally do not need to use insulin treatment. Diet adjustment or oral hypoglycemic drugs are enough to control blood glucose level.
Pentacyclic triterpenoid compounds are secondary plant metabolites found in a variety of plant organs, and the content of which in some species is up to 30% of their dry weight. Although the molecular mechanism is still unclear, triterpenoid compounds are generally considered as important components of plant defense systems against pathogens and herbivores. It has been reported that some glycoside pentacyclic triterpenoid compound have the same or higher in vitro anti influenza virus activity as oseltamivir. Mechanism studies show that these compounds closely bind to hemagglutinin (HA) protein, thus destroying the interaction between hemagglutinin and sialic acid receptor and preventing viruses from entering host cells. Such process hardly lead to drug resistance. At the same time, studies have shown that pentacyclic triterpenoid compounds can bind to the N protein of the coronavirus, prevent the assembly of the virus, and achieve the anti-coronavirus effect. At the same time, the N protein of coronavirus is highly conservative and plays an important role in immunity. Therefore, compounds targeting N protein are potential antiviral small molecule compounds.
For saccharide medicine, oxygen glycosides and nitrogen glycosides are easy to be oxidized and metabolized in vivo, while carbon glycosides show good metabolic stability both in vivo and in vitro, which makes carbon glycosides widely concerned by scientists. Therefore, pentacyclic triterpenoid carbon glycoside compounds have a very bright prospect in the research and development of hypoglycemic drugs and antiviral drugs.
In conclusion, there is an urgent need to develop new pentacyclic triterpenoid carbon glycosides in this field.

i. Experimental Materials
After the animals arrived at WuXi AppTec facilities, they were kept in the animal feeding room with strictly controlled environmental conditions. The temperature was kept at 20-24° C. and the humidity was kept at 30-70% in the feeding room. The temperature and humidity of the feeding room were monitored in real time through the temperature and humidity meter, and the temperature and humidity were recorded twice a day (once in the morning and once in the afternoon). The lighting in the animal feeding room was controlled by an electronic timing lighting system, which was turned on for 12 hours every day and turned off for 12 hours (on at 7:00 a.m. and off at 19:00 p.m.). During the experiment, the animals were raised in a single cage and toys were provided for mice in each cage. During the experiment, the animals freely took food (growth/reproduction feed for rats and mice) and water.
After the animals arrived, they can adapt to the environment for 1-2 weeks before conducting the experiment.
ii. Drug Preparation and Administration
1) Preparation of liquid medicine: each compound was prepared on the first day of the experiment, and then stored in a 4° C. refrigerator for use on the next day.
2) Administration: After grouping, animals in each group were administered 0.5 hours before sugar administration.
3) Oral glucose tolerance experiment: sugar was administrated to the animals by gavage 0.5 hour after the end of the animal administration, and the time of sugar administration was recorded as 0 min. The oral dose of glucose was 5 g/kg, 10 ml/kg. The blood glucose of animals was detected before administration, before sugar administration, and 15, 30, 60, 90, and 120 minutes after sugar administration. The blood glucose was detected with a blood glucose meter and the corresponding blood glucose test paper.
iii. Experimental Results
The results showed that oral administration of pentacyclic triterpenoid carbon glycosides could effectively reduce the postprandial blood glucose level of ICR mice (

Negative control: DMSO
Positive control: INT777 (TGR5 receptor agonist)
Test tool: HTRF kit
Others: KRBH buffer, BSA, DPP4 inhibitor
STC-1 cells were seeded with a certain density. After the cells adhered to the wall overnight, they were starved with KRBH buffer, while BSA was used to maintain nutrition, and degradation of GLP-1 was reduced with DPP4 inhibitors. After 1 h, they were replaced with glucose free or glucose containing KRBH buffer to stimulate GLP-1 secretion. At the same time, compounds of certain concentrations were added. After 1 h of treatment, supernatant was collected and tested for GLP-1 concentration with HTRF kit. The secretion of LDH was also detected to indicate the toxicity of the compounds.
The experimental results showed that A64 had a good in vitro effect of promoting GLP-1 secretion, and its in vitro EC50 was 7.231 μM, which is obviously superior to the positive compound INT777 (EC50=22.82 μM) (

The results showed that pentacyclic triterpenoid carbon glycosides can produce effective pharmacological activity against influenza virus, in which A2 has the same virus inhibition rate and low cytotoxicity as the positive drug zanamivir, similar virus inhibition rate to that of the positive drug ribavirin, but lower cytotoxicity than that of ribavirin (
N protein diluent: 20 μg/mL
Buffer solution: 10 mM HEPES, pH 7.4, 150 mM NaCl, 3.0 mM EDTA, and 0.005% (v/v) surfactant P20, 5% DMSO.
Instrument: Biacore 8K (GE Healthcare)
Biacore 8K (GE Healthcare) was used to test the affinity between the compound with N protein by surface plasmon resonance (SPR). Firstly, the N proteins were diluted to 20 μg/mL, standard amino coupling method was used to couple the full length N proteins to CM5 chip respectively at 25° C., with the signal value of 10,000 signal units (RU). The running buffer used was 10 mM HEPES, pH 7.4, 150 mM NaCl, 3.0 mM EDTA, and 0.005% (v/v) surfactant P20, 5% DMSO. 10 mM of DMSO stock solution of the compound was diluted to 7 gradient concentrations (1.56 μM-100 μM) with running buffer. During the test, the instrument was initialized for three times using the running buffer, then the test compounds were injected and flown through the chip in turn, and the binding and dissociation time were set as 100 seconds. After one cycle, 50% DMSO was used to wash the remaining compounds on the chip and continued with the next cycle. Finally, solvent correction was carried out with running buffer solution containing 4.5%-5.8%. According to the generated spectrum, the value of the control group was deducted and solvent correction was conducted. The data was generated using the Biacore 8K data processing software and KD values were calculated by the static affinity model according to the fixed Rmax value.
The results show that pentacyclic triterpenoid carbon glycosides have enhanced affinity with N protein, and Ki of some compounds were less than 10 μM. (
