[0001] The present application relates to the technical field of medicine, in particular to a polycyclic polyisoprenyl phloroglucinol compound extracted and separated from the aboveground part of Hypericum sampsonii Hance, a preparation method thereof and application of the polycyclic polyisoprenyl phloroglucinol compound in preparation of a drug for treating hepatocellular carcinoma. BACKGROUND
[0002] Hepatocellular carcinoma (HCC) is the most common type of primary liver cancer, accounting for 75-90% of all liver cancer cases, which mainly originates from the malignant transformation of hepatocytes, and its clinical manifestations mainly include liver pain, liver function abnormalities, metastasis symptoms and cancer syndrome, etc. The incidence of HCC is closely related to chronic liver diseases (such as cirrhosis and viral hepatitis), and HCC has high invasiveness and metastasis tendency, and the early symptoms are occult, and the prognosis in the middle and late stages is poor.
[0003] At present, the main treatment for HCC is chemotherapy, but the complex tumor microenvironment, tumor heterogeneity and genetic mutations and other factors limit the effect of existing therapies. In recent years, multi-target kinase inhibitors, sorafenib, atezolizumab, bevacizumab and lenvatinib and other systemic chemotherapy drugs have been approved as first-line treatment options for advanced HCC. However, these therapies can improve patient survival, but can also cause serious side effects such as hypertension, diarrhea, loss of appetite, weight loss and other serious side effects, further damaging the overall health of patients. In addition, the current clinic is still facing the problem of drug resistance of many existing anticancer drugs. Therefore, accelerating the development of new drugs for treating hepatocellular carcinoma has become a major challenge that needs to be addressed in the clinic.
[0004] Natural small molecules are an important source of antitumor drugs, and according to statistics, 49% of existing anticancer small molecule drugs are related to natural small molecules or their derivatives. China has rich resources of medicinal plants, which have rich structural diversity and biocompatibility, and many drug source molecules have been found from natural small molecules. Therefore, finding natural small molecule drugs for treating HCC from medicinal plants to meet the clinical demand is an important way to develop new anti-HCC drugs. SUMMARY

[0043] Example 2: Intervention of Attenuatumione D on H22 cell-induced hepatocellular carcinoma in nude mice by subcutaneous injection Pharmacological evaluation of the effect
[0044] 1. Experimental samples
[0045] Preparation of the solution of the sample to be tested: the polycyclic polyprenyl depsidate compound of the application Attenuatumione D was prepared as described in Example 1. An appropriate amount of sample was accurately weighed and dissolved in DMSO to obtain a stock solution at 10 mM, to be used in the pharmacological tests.
[0046] 2. Experimental subjects
[0047] BALB / c nude mice (male, SPF grade, 7-8 weeks old) weighing 20 ± 2 g were used. The mice were acclimatized in a sterile environment for three days before the experiment.
[0048] 3. Experimental method
[0049] 3.1. Establishment of the hepatocellular carcinoma nude mouse model
[0050] The BALB / c nude mice were acclimatized in a sterile environment (temperature 22 ± 2°C, humidity 60% ± 5%, 12 hours light / 12 hours dark cycle) for three days before the experiment. All operations were carried out in strict accordance with the "Guidelines for the Management of Laboratory Animals" and the relevant regulations of the People's Republic of China, while referring to GB / T 35892-2018 "Guidelines for the Welfare and Ethical Review of Laboratory Animals". 1 x 10 7 H22 tumor cells were transplanted subcutaneously into the mesentery of the nude mice in a volume of 0.2 mL, ensuring that the required number of cells for the experiment was sufficient.
[0051] 3.2. Administration method and tissue sampling
[0052] Twenty male BALB / c nude mice were randomly divided into four groups (n = 5 for each group) 24 hours after the subcutaneous injection of H22 cells in the previous step, and intravenous administration was performed daily for 16 consecutive days. The groups were as follows:
[0053] Group I, type (saline); group II, CTX (25 mg / kg BW); group III, Attenuatumione D (25 mg / kg BW); group IV, Attenuatumione D (50 mg / kg BW).
[0054] The blank group was physiological saline, the positive control group was cyclophosphamide (CTX), and the administration groups were 25 mg / kg / day and 25 mg / kg / day. The dose of the administration groups was selected according to the pre-experiment, which showed no toxic effect on nude mice. On the last day, all nude mice were weighed and sacrificed, and then the tumors were removed and weighed.
[0055] 3.3 Inhibition rate of tumor
[0056] The anti-tumor effect was expressed as the inhibition rate of tumor (%), and the calculation formula was: inhibition rate (%) = [model group (tumor weight; g) - treatment group (tumor weight; g) / model group (tumor weight; g)] x 100.
[0057] 3.4 Histological analysis
[0058] The liver tissues of each group were fixed with formalin (10% neutral buffer), dehydrated with gradient ethanol, transparentized with xylene, and embedded with paraffin. The tumor tissues were cut from the middle and cut into 4 μm thick sections, which were stained with hematoxylin and eosin (H&E) and observed under a microscope.
[0059] 3.5 Serum metabolomics analysis
[0060] 100 mL of serum sample was taken and 300 mL of methanol was added for extraction. After incubation in ice bath for 10 minutes, centrifugation was performed at 4°C (13,000 rpm) for 10 minutes. The supernatant was freeze-dried and resuspended with 50 mL of methanol / water (3:1 by volume). After centrifugation at 4°C (13,000 rpm) for 10 minutes again, the supernatant was collected for analysis. To ensure the consistency of the experimental conditions and the quality of the data, all extracted tissues or serum samples were mixed to prepare a quality control sample (QC) for serum metabolomic analysis. The pretreatment process of the quality control sample was synchronized with the experimental samples.
[0061] A Vanquish Ultra Performance Liquid Chromatography system (Thermo Fisher Scientific, Waltham, USA) coupled with an Orbitrap Exploris 120 mass spectrometer was used. The Hypersil GOLD C18 column (100 mm x 2.1 mm, 1.9 mm, Thermo Fisher Scientific) was used for analysis. The mobile phase A was water containing 0.1% formic acid, and the mobile phase B was acetonitrile containing 0.1% formic acid. The gradient elution program was set as follows: 0-5 min 5% B, 0.5-20 min 5%-100% B, 20-27.9 min 100% B, 28-30 min 5% B. The flow rate was 0.30 mL / min, and the column oven was set at 40 °C. The injection volume was 5 mL for each analysis, and the sample order was randomly arranged. The mass spectrometry scan range was set between 50 and 1000 m / z, and the ion spray voltage was set at 3200 V in the electrospray ionization mode, with the vaporizer temperature maintained at 350 °C. In the electrospray ionization mode, the hydrogen-deuterium collision energy (%) was set at 30, 60, or 90, respectively. The temperature was maintained at 4 °C during the analysis of all samples.
[0062] 4. Analysis of experimental results
[0063] 4.1 Anti-tumor effect of Attenuatumione D in vivo
[0064] As shown in Figure 1, to fully evaluate the anti-tumor activity of Attenuatumione D, a H22 hepatocellular carcinoma nude mouse model was established (A), the body weight of nude mice (B), the morphological changes of tumors (C), and the tumor weight (D) were determined. Figure 1 Figure 1 Figure 1 Figure 1 Figure 1
[0065] 4.2 Body weight
[0066] To evaluate the effect of Attenuatumione D on the growth status and body weight of mice, we studied the drug-induced toxicity as an indicator. As shown in Figure 2, the body weight of the mice in the control group increased gradually, while the body weight of the mice in the treatment group decreased significantly, indicating that Attenuatumione D had a significant effect on the growth status and body weight of the mice. Figure 1 As shown in Figure B, the initial body weights of all nude mice in this study were similar, with no significant difference (p>0.05). However, the final body weight of the model group (33.98±1.47g) was significantly higher than that of the CTX-treated group (30.60±1.17g), indicating that CTX has significant side effects. Furthermore, the physiological state of the mice in the Attenuatumione D-treated group was better than that of the model group and the CTX group, exhibiting smooth skin, normal growth, frequent activity, and rapid response. Meanwhile, the initial and final weight gain rates of the Attenuatumione D-treated group (250 or 500 mg / g BW; 1.40±0.06 or 1.42±0.10) were not significantly different from those of the model group (1.39±0.06), indicating that the mice in this treatment group did not exhibit the aforementioned side effects and toxicity signs.
[0067] 4.3 Histopathological Analysis
[0068] like Figure 2 As shown, this study used hematoxylin-eosin (H&E) staining to observe morphological changes in liver tissue under a microscope. Figure 2 As shown in Figure A, the hepatocytes in the control group were neatly arranged, exhibiting a typical clustered structure, and there was clear evidence of blood flow through the sinusoidal spaces formed by the central vein. Figure 2 (B). However, compared with the control group, the liver tissue of the model group (HCC-induced tumor-bearing mice) showed features such as lymphoma proliferation, hepatic vascular congestion, and hepatocyte atypia and degeneration. Figure 2 In HCC, not only does portal vein congestion occur, but the volume and number of lymphoid tissue surrounding the vein also increase. Furthermore, the dilation and congestion of the central vein indicate impaired blood flow in this area, possibly due to the accumulation of atypical hepatocytes and lymphoid tissue. Some hepatocytes exhibit ballooning degeneration and microfatty degeneration, hallmarks of HCC-induced cell damage. H&E staining of Attenuatumione D group mice treated with HCC (+50 mg / kg) showed mild mononuclear inflammatory aggregation, with only slight swelling and vacuolar degeneration of hepatocytes. In particular, the Attenuatumione D group significantly reduced hepatic vascular congestion, decreased hepatocyte microfatty degeneration, and enhanced macrophage activity. This study suggests that the presence of macrophages indicates that the liver is responding to inflammation or damage and actively clearing toxins and other harmful substances from the body. Figure 2C and D). In addition, the liver sections of HCC + 50mg / kg attenuatumione D group mice showed that the hepatocytes were arranged in cord-like structures, relatively intact, which indicated that their functions were gradually restored to normal levels. The experimental results showed that the 50mg / kg dose of attenuatumione D treatment not only improved the cell histological features, but also minimized the degree of liver damage such as coagulopathy and vacuolar degeneration, and was more effective in improving liver histology.
[0069] 4.4 Attenuatumione D reversed the abnormal purine metabolism in serum of HCC nude mice
[0070] Metabolomics analysis showed that there were significant changes in three metabolites Figure 3 ). The most significant differential metabolites in the drug administration group compared to the model group were Inosine, Guanine and Hypoxanthine in purine metabolism. Abnormal purine metabolism promotes chronic inflammatory response and plays a key role in various biological processes of cancer cells. Abnormal purine metabolism has been found in various cancers including HCC and is considered an important mechanism for increasing cancer risk. Studies have shown that the abnormality of purine metabolism in the model group is increased, and after administration, the level of purine metabolism is significantly reduced, and the metabolite level of the drug administration group at a dose of 50mg / kg / day of attenuatumione D is close to that of the positive drug. The above research results show that attenuatumione D can significantly reverse the abnormal purine metabolism of hepatocellular carcinoma nude mice to normal levels.
[0071] The above results show that the polycyclic polyisoprenyl phloroglucinol compound attenuatumione D of the present application can significantly reduce the tumor weight of hepatocellular carcinoma nude mice at a dose of 25mg / kg and 50mg / kg, reverse the abnormal purine metabolism of hepatocellular carcinoma nude mice, and can be used for preparing a therapeutic drug for hepatocellular carcinoma.

It should be noted that for those skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, and the present application also intends to include these modifications and improvements.
