Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of biomedicine, and in particular relates to the application of a traditional Chinese medicine compound lulutong acid in the preparation of an anti-hepatitis B virus drug. Background Art
[0002] Hepatitis B is an infectious liver disease caused by the hepatitis B virus (HBV). Its main transmission routes include blood transmission, mother-to-child transmission and sexual transmission. After the hepatitis B virus enters the liver cells, through the processes of viral replication, transcription and assembly, the virally replicated hepatitis B surface antigen, hepatitis B e antigen and hepatitis B core antigen are released on the liver cell membrane, stimulating the human immune system to identify and react. This antigen-antibody reaction on the liver cell membrane can cause damage and destruction of liver cells, resulting in a series of clinical symptoms, which can cause chronic infection and a high risk of developing cirrhosis and liver cancer.
[0003] At present, the commonly used drugs for the treatment of hepatitis B virus mainly include nucleoside analogs, interferon drugs, etc., but these drugs either have a long treatment cycle, are prone to cause drug-resistant mutations of HBV virus, or have more adverse reactions. Therefore, it is urgent to continuously develop new therapies and safer and more effective drugs on the existing basis to achieve functional cure of HBV. As an effective choice for disease treatment, Chinese herbal medicines have a significant effect on disease treatment, whether it is the use of prescriptions or the application of monomer compounds. At present, there are many schemes that have proposed anti-hepatitis B virus prescriptions or monomer compounds, which can not only improve the patient's liver function and regulate the body's immune function, but also have relatively few side effects, and patients have good compliance and tolerance.
[0004] Betulonic acid is a triterpenoid compound isolated from the Chinese herbal medicine Liquidambar formosana Hance (the dried mature infructescence of Liquidambar formosana Hance, a plant of the Hamamelidaceae family). Its molecular formula is C 30 H 46 O3, molecular weight is 454.34, structural formula is as follows:
[0005]
[0006] Studies have shown that lulutong acid has multiple biological effects such as anti-inflammatory, analgesic, antibacterial, and anti-tumor.
[0007] However, there are currently no research reports on the inhibitory effects of lumefantrine on HBV replication and transcription, as well as its anti-HBV effects. Summary of the invention
[0008] In view of this, the primary purpose of the present invention is to provide the use of passutonic acid in the preparation of anti-hepatitis B virus drugs. The present invention determines that passutonic acid has a significant inhibitory effect on hepatitis B virus (HBV), providing a new solution for the development of new drugs against hepatitis B virus. Passutonic acid, as a traditional Chinese medicinal material, has abundant medicinal resources and low cost, and is of great significance to the development of anti-hepatitis B virus drugs.
[0009] In order to achieve the above object, the present invention adopts the following technical solutions:
[0010] One aspect of the present invention provides the use of lulutonic acid in the preparation of anti-hepatitis B virus drugs.

[0014] c: Inhibit the expression of hepatitis B virus mRNA;
[0015] d: Inhibit the expression of HBV transcription factors;
[0016] e: Treatment of hepatitis B.
[0017] Another aspect of the present invention provides an anti-HBV drug containing an effective concentration of lulutonic acid.
[0018] Beneficial effects of the present invention:
[0019] The present invention has been tested and confirmed through a large number of experiments that lulutong acid has a significant inhibitory effect on hepatitis B virus (HBV). Lulutong acid can inhibit the production and replication of hepatitis B virus antigens, inhibit the expression of hepatitis B virus mRNA and inhibit the expression of HBV transcription factors. It is also confirmed through a hepatitis B mouse model that lulutong acid has the effect of treating and controlling hepatitis B, providing a new idea for the development of hepatitis B drugs.
[0020] In addition, as a traditional Chinese medicine compound, lulutong acid has a wide source, is easy to extract, and has low cost.

[0061] Example 1 Toxicity test of lulutong acid on HepG2.215 cells
[0062] In this example, the CCK8 cytotoxicity test was used to detect the toxicity of different concentrations of passutonic acid on HepG2.215 cells to preliminarily determine the safe concentration range of passutonic acid on HepG2.215 cells. The specific steps are as follows:
[0063] HepG2.215 cells were inoculated into 96-well plates with 20,000 cells per well in DMEM growth medium containing 10% fetal bovine serum, and cultured in an incubator at 37°C and 5% CO2. When the cells grew to a confluence of about 70%, the 10mM stock solution of passepartout acid prepared by dissolving DMSO in passepartout acid dry powder was diluted with DMEM growth medium to different dosing concentrations of 5μM, 10μM, 15μM, 20μM, 25μM, 30μM, 35μM, and 40μM, respectively. The medium in the 96-well plate was replaced with 100μL of growth medium containing the drug per well. A control group (giving an equal volume of DMSO) and a blank group (without cells) were set up at the same time, with 3 replicates in each group. The cells were cultured in an incubator at 37°C and 5% CO2 for 48h. After 48 hours, discard the supernatant and add 100 μL of DMEM growth medium containing 10% CCK8 cytotoxicity detection solution. Continue to culture in an incubator at 37°C, 5% CO2 for a suitable period of time. Measure the OD value at 450nm using a microplate reader. For the results, see Figure 1 .
[0064] pass Figure 1 It can be seen that lulutong acid has low drug toxicity to HepG2.215 cells within a dosage concentration of 30 μM.
[0065] Example 2 Drug toxicity of thiamethoxam acid to HepG2.215 cells at safe concentrations
[0066] Based on the results in Example 1, flow cytometry was used in this example to further determine the drug toxicity of lulutonic acid to HepG2.215 cells at a safe dosing concentration, and the specific steps were as follows:
[0067] HepG2.215 cells were plated in a six-well plate in DMEM growth medium containing 10% fetal bovine serum, with about 500,000 cells in each well. When the HepG2.215 cells grew to a confluency of about 70% in the 6-well plate, the 10mM stock solution of 10μM, 10μM, 15μM, and 20μM of the drug were diluted with the above culture medium, and the culture medium containing 100μL of 1 ... Figure 2 .
[0068] pass Figure 2 It can be seen that compared with the control group, lulutong acid has extremely low cytotoxicity to HepG2.215 cells at a dosage concentration of less than 20 μM.
[0069] Example 3 Inhibitory effect of different concentrations of lumefantrine on the production of HBsAg and HBeAg in HepG2.215 cells
[0070] Hepatitis B surface antigen (HBsAg) is the earliest and most important marker of hepatitis B virus infection, and hepatitis B e antigen (HBeAg) is a marker of hepatitis B virus replication. In this embodiment, the inhibitory effect of lulutonic acid on the production of HBsAg and HBeAg by HepG2.215 cells at different administration concentrations was detected by enzyme-linked immunosorbent assay. The specific steps are as follows:
[0071] HepG2.215 cells were plated in 12-well plates and cultured in the same manner as in Example 1. When the HepG2.215 cells grew to a confluency of about 70% in the 12-well plate, the culture medium was discarded, and the thiabendazole was diluted to 10 μM and 20 μM with new DMEM growth medium. A control group (DMSO with the same drug volume) was set up at the same time, with 3 replicates in each group. The cells were cultured in an incubator at 37°C and 5% CO2 for 48 hours. The supernatant of the culture medium was then aspirated and tested according to the instructions of the enzyme-linked immunosorbent assay kit. The OD value was tested on an enzyme reader. The results can be found in Figure 3 .
[0072] pass Figure 3 It can be seen that with the increase of the concentration of lulutong acid, the amount of HBsAg and HBeAg produced by HepG2.215 cells decreased ( Figure 3 a and Figure 3 b), there was a significant difference compared with the control group. The results showed that lulutong acid had a significant inhibitory effect on the production of HBsAg and HBeAg in HepG2.215 cells at a concentration of 10μM and 20μM. Compared with the control group, * indicates a significant difference (P<0.05); ** indicates an extremely significant difference (P<0.01); *** indicates a more significant difference (P<0.001); **** indicates a particularly significant difference (P<0.0001).
[0073] Example 4 Inhibitory effect of different concentrations of lulutong acid on mRNA expression in HepG2.215 cells
[0074] The level of HBV mRNA reflects the activeness of HBV infection. A high level of HBV mRNA indicates active viral replication and strong infectivity. In this example, the inhibitory effect of different concentrations of lulutonic acid on mRNA expression in HepG2.215 cells was determined by real-time fluorescence quantitative PCR, and the specific steps are as follows:
[0075] Using the same cell plating and culture method as in Example 3, RNA was extracted from HepG2.215 cells 48 hours after administration, and then the reverse transcription kit ( Plus All-in-one 1st Strand cDNASynthesis SuperMix (gDNAPurge)) instructions for reverse transcription. Dilute cDNA ten-fold as a template and configure the qPCR system: 2μL diluted cDNA per well of a 96-well plate, 7μL ddH2O, 10μL SYBR, and 0.5μL each of upstream and downstream primers. The primer information involved is shown in the following table:
[0076]
[0077] According to the kit ( Real-time fluorescence quantitative PCR was performed using the qPCR program in the SYBR qPCR SuperMix Plus manual. The control group without drug administration was used as a reference to calculate the relative expression of totalRNA and pgRNA and evaluate the changes in mRNA expression. Figure 4 .
[0078] pass Figure 4 It can be seen that compared with the control group, lulutong acid at a concentration of 20 μM had a significant inhibitory effect on the mRNA expression of HepG2.215 cells ( Figure 4 a and Figure 4 b). Among them, * indicates significant difference (P<0.05); ** indicates extremely significant difference (P<0.01).
[0079] Example 5 The inhibitory effect of thiabendazole on the expression of HBV transcription factors.
[0080] HBV transcription factors play a very important role in the replication and expression of hepatitis B virus. High expression levels or active expression of HBV transcription factors will promote the replication and expression of HBV virus, thereby promoting the development of hepatitis B. In this example, Western blot was used to study the inhibitory effect of thiabendazole on the expression of HBV transcription factors (PPARγ, PGC1α, HNF4α and HNF1α), and the specific steps are as follows:
[0081] HepG2.215 cells were cultured and administered in the same manner as in Example 2. After 48 hours, the cells were collected, washed twice with PBS, and the supernatant was discarded. 200 μL of protein lysis buffer NP-40 was added to lyse the cells on ice for 40 to 60 minutes, centrifuged at 12000 rpm for 15 minutes, and the supernatant was transferred to another clean EP tube. After the concentration of the supernatant was determined by the BCA kit, protein samples of the same concentration were prepared. Then, the protein bands of different transcription factors were detected by Western blot. The test results are shown in Figure 5 .
[0082] pass Figure 5 It can be seen that lulutong acid has a significant inhibitory effect on the protein expression of HBV transcription factors at the dosage concentration of 10μM and 20μM, and has a certain dose-effect relationship.
[0083] Example 6 Construction of a hepatitis B mouse model to study the effect of lulutong acid in the hepatitis B mouse model
[0084] In this example, a hepatitis B mouse model was constructed to further study and determine the therapeutic effect of lulutonic acid on hepatitis B virus. The specific steps are as follows:
[0085] 1. Construction of hepatitis B mouse model
[0086] 6-8 weeks old CL57 mice were injected with HBV virus AAV8[HBV-D,ayw](D#2012) (PBS diluted) into the eye sockets once a week for a total of two injections. Then, the mice were bled from the eye sockets to detect HBsAg and HBeAg in the serum of the mice to determine whether the model was successfully constructed.
[0087] 2. Drug administration experiment
[0088] The successfully constructed hepatitis B mouse model was divided into an experimental group and a control group. The mice in the experimental group were intraperitoneally injected with 20μM 100μL of 10μM ...
[0089] 3. Immunohistochemical detection of HBcAg and HBsAg in mouse liver
[0090] After the mice were killed by cervical dislocation, fresh livers of mice in the control group and experimental group were fixed in 4% paraformaldehyde and embedded in paraffin. The fixed tissue samples were embedded in paraffin and 3-4 μm sections were made. The paraffin sections were dewaxed in xylene and hydrated through an alcohol gradient to remove the paraffin and restore the natural state of the tissue. The sections were treated with antigen recovery solution. The sections were treated with a 3% hydrogen peroxide aqueous solution to inactivate endogenous peroxidase, and nonspecific binding sites were blocked with a blocking solution. The sections were incubated with primary antibodies (Rabbit anti-HbsAg and Mouse anti-HbcAg) and incubated at room temperature for 60 minutes before the secondary antibodies (Goat anti-mouse IgG (H+L) Antibody and Goat anti-rabbit IgG (H+L) Antibody) labeled with horseradish peroxidase (HRP) were used to bind to the primary antibodies. DAB was used as a color developer to observe the location of the target antigen under an optical microscope.
[0091] See the results Figure 6 and Figure 7 .
[0092] in, Figure 6 The figure shows the changes in HBsAg expression in mouse serum after a period of treatment with lulutong acid. It can be seen that compared with the control group, the HBsAg expression in the serum of hepatitis B mice in the experimental group has a significant decreasing trend.
[0093] Figure 7 The figure shows the detection of HBcAg and HBsAg in the liver of mice after administration of lulutong acid. It can be seen that compared with the control group, the cell membrane and nucleus color expression in the liver cells of the experimental group of mice was weaker, which indicates that the hepatitis B condition of the mice in the experimental group treated with lulutong acid was under control, indicating that lulutong acid has obvious anti-hepatitis B virus effect.
