Abstract
Description
Technical Field
[0001] This invention relates to the field of biomedical technology or health products, and in particular to the application of cholesterol sulfate in lowering cholesterol and / or lowering hyperlipidemia. Background Technology
[0002] Hyperlipidemia is a common metabolic disease characterized by elevated levels of plasma triglycerides or cholesterol, and low-density lipoprotein cholesterol (LDL-C), leading to abnormal lipid metabolism and endothelial cell loss. It is a major risk factor for many cardiovascular and cerebrovascular diseases, including atherosclerotic cardiovascular disease. Currently, with economic development and significant changes in dietary structure and lifestyle, the average lifespan of Chinese people is gradually increasing, leading to a continuous rise in the incidence of hyperlipidemia, seriously endangering human health. Although cholesterol metabolic homeostasis has been extensively studied over the past century, increasing evidence suggests that cholesterol metabolism disorders are closely related to cardiovascular and cerebrovascular diseases and other illnesses. Past research has deepened our understanding of cholesterol metabolism under physiological and pathological conditions and provided new targets and strategies for the treatment of cholesterol-related diseases. Currently, HMGCR inhibitors—statins—are widely used to treat cardiovascular diseases. However, the efficacy of statins is limited by compensatory increases in HMGCR protein. Although ezetimibe and PCSK9 inhibitors can further reduce LDL-C levels in hyperlipidemic patients taking statins, further research is needed to find more effective and safer methods with fewer side effects to lower cholesterol.
[0003] Bacteroides is a crucial genus of gut bacteria, accounting for over 40% of the total. A study published in *Nature Microbiology* in August 2022 revealed for the first time that *Bacteroides* gut bacteria are specific species responsible for sulfonating cholesterol, converting it to cholesterol sulfate (CHS) via cholesterol sulfonate transferase (SULT2B1b), elucidating the mechanism by which gut microbiota participates in cholesterol metabolism. Cholesterol sulfate is widely distributed in the human body, including the skin, adrenal glands, liver, lungs, brain, and endometrium. The concentration of cholesterol sulfate in human plasma ranges from 134 to 322 μg / mL. A study published in *Nature Communications* in July 2022 discovered for the first time the mechanism of action of cholesterol sulfate against ulcerative colitis. Cholesterol sulfate binds to the Niemann-Pick C2 protein, activating sterol regulatory element-binding protein 2 in colonic epithelial cells, promoting cholesterol biosynthesis, and thus alleviating ulcerative colitis. The feedback regulation of host cholesterol effects by cholesterol sulfate remains unclear. Summary of the Invention

[0069] To better illustrate the purpose, technical solution, and advantages of the present invention, the present invention will be further described below in conjunction with specific embodiments.

[0071] To better understand the essence of this invention, the following will combine pharmacological experiments and results on P407-induced hyperlipidemia mice, high-cholesterol diet-induced hypercholesterolemia mice, and dexamethasone and fructose-induced hypercholesterolemia rats to illustrate its role in the preparation of drugs and health products for the treatment or prevention of hyperlipidemia and hypercholesterolemia.
[0072] Example 1: Effects of cholesterol sulfate on P407-induced hyperlipidemia in mice
[0073] 1. Experimental Methods
[0074] Sixty SPF-grade male C57BL / 6j mice (22-24g) were randomly divided into six groups: normal control group, P407 group, atorvastatin group (AVT group, 10 mg / kg), ezetimibe group (EZ group, 10 mg / kg), low-dose cholesterol sulfate group (CHS-L, 100 mg / kg), and high-dose cholesterol sulfate group (CHS-H, 200 mg / kg), with 10 mice in each group. All C57BL6j mice underwent daily intraperitoneal injection of P407 400 mg / kg to induce a hyperlipidemia model, and were treated with the corresponding drug 1 hour after model establishment. The normal control group and P407 group received the corresponding drug solvent. Treatment continued for 6 days. On the seventh day, all mice were sacrificed after blood was collected via the orbital vein for analysis.
[0075] Observation indicators:
[0076] (I) Lipid-related indicators in serum, liver, bile and feces: TG, TC, HDL-C, LDL-C, TBA;
[0077] (II) Pathological examination: liver HE staining and Oil Red O staining;
[0078] (III) Expression of intestinal cholesterol absorption-related indicators mRNA and protein;
[0079] (IV) Expression of hepatic cholesterol synthesis-related indicators mRNA and protein;
[0080] (V) Expression of hepatic cholesterol metabolism-related indicators mRNA and protein;
[0081] (VI) Expression of cholesterol transport mRNA and protein in the liver.
[0082] 2. Experimental Results
[0083] (2.1) Effects on cholesterol levels in mice
[0084] like Figure 1 As shown, compared with the normal group, the serum TG, TC, serum LDL-C and liver TC levels of mice in the P407 group were significantly increased ( P The serum HDL-C level was significantly lower than 0.01, indicating a successful establishment of the hyperlipidemia model. Compared with the P407 group, the serum TG, TC, serum LDL-C, and liver TC levels were significantly lower in the AVT group, EZ group, and low- and high-dose cholesterol sulfate groups. Notably, serum HDL-C levels did not change significantly after cholesterol sulfate treatment, but showed an increasing trend after AVT treatment, suggesting that the lipid-lowering mechanism of cholesterol sulfate may differ from that of statins.
[0085] (2.2) Effects on lipid accumulation in mouse liver
[0086] Oil Red O staining results as follows Figure 2 As shown, compared with the normal group, the area of Oil Red staining positive in the P407 group mice was significantly increased; compared with the P407 group, administration of AVT, EZ and cholesterol sulfate could significantly reduce the area of Oil Red staining positive in the liver, indicating that cholesterol sulfate has the effect of reducing lipid deposition in the liver.
[0087] (2.3) Effects on cholesterol excretion in mice
[0088] like Figure 3 As shown, the results indicated that, compared with the normal group, P407 reduced the cholesterol content in the large intestine contents of mice; compared with the P407 group, administration of the positive control drug EZ and cholesterol sulfate significantly increased the cholesterol content in the large intestine contents of mice, suggesting that cholesterol sulfate may exert its cholesterol-lowering effect by promoting cholesterol excretion. The positive control drug AVT did not lower cholesterol by promoting cholesterol excretion, while the positive control drug EZ did lower cholesterol by promoting cholesterol excretion.
[0089] (2.4) Effects on bile acid levels in mice
[0090] like Figure 4 As shown, the results indicated that, compared with the normal group, P407 modeling increased hepatic TBA levels, suggesting that P407 may feedback-inhibit hepatic TBA synthesis. Compared with the P407 group, after administration of the positive control drug AVT, hepatic TBA levels decreased, bile TBA levels increased, but fecal TBA levels were unaffected, suggesting that AVT may promote the enterohepatic circulation of TBA. The positive control drug EZ increased TBA levels in both bile and feces, indicating a TBA-promoting effect from bile and feces. After administration of cholesterol sulfate, hepatic TBA levels decreased, while bile acid levels in bile and large intestine contents significantly increased, suggesting that cholesterol sulfate may promote cholesterol metabolism to bile acids and promote bile acid excretion, thereby exerting a lipid-lowering effect.
[0091] (2.5) Effects on mRNA and protein of cholesterol absorption in mouse intestines
[0092] like Figure 5 As shown, the results indicated that, compared with the control group, the mRNA levels of NPC1L1 and ACAT2 in the small intestine of mice in the P407 group were not significantly affected. Compared with the P407 group, the positive control drug EZ significantly downregulated the mRNA expression of NPC1L1 in the small intestine of mice, but had no significant effect on the mRNA and protein expression of ACAT2; however, cholesterol sulfate administration significantly downregulated the mRNA and protein expression of both NPC1L1 and ACAT2, suggesting that cholesterol sulfate may reduce cholesterol absorption by inhibiting cholesterol absorption and esterification, thereby playing a role in lowering cholesterol, while the positive control drug EZ only inhibited cholesterol absorption.
[0093] (2.6) Effects on cholesterol synthesis mRNA in mouse liver
[0094] like Figure 6 , 7 As shown, the results indicated that, compared with the control group, the P407 group significantly upregulated the mRNA expression levels of hepatic SREBP2, HMGCR, SM, and SCAP, downregulated the mRNA expression level of INSIG1, and reduced the translocation of SREBP2 into the nucleus. Compared with the P407 group, the positive control drug AVT significantly downregulated the mRNA expression levels of hepatic SREBP2, HMGCR, and SCAP, and promoted the translocation of SREBP2 into the nucleus. Cholesterol sulfate administration significantly downregulated the mRNA expression levels of hepatic SREBP2, HMGCR, SM, and SCAP, upregulated the mRNA expression level of INSIG1, and promoted the translocation of SREBP2 into the nucleus; suggesting that cholesterol sulfate, like the positive control drug AVT, can inhibit hepatic cholesterol synthesis.
[0095] Unlike AVT, a positive control drug that acts as an HMGCR inhibitor, cholesterol sulfate administration has a more significant effect in downregulating the mRNA expression of SREBP2 in the liver. It can comprehensively downregulate the mRNA expression levels of SREBP2, HMGCR, SM, and SCAP, upregulate the mRNA expression level of INSIG1, and promote the translocation of SREBP2 into the cell nucleus.
[0096] (2.7) Effects on hepatic cholesterol and bile acid metabolism mRNA and protein
[0097] like Figure 8As shown, the results indicated that, compared with the control group, the P407 group significantly downregulated the mRNA and protein expression levels of CYP7A1 in mouse liver. Compared with the P407 group, the positive control drug AVT had no significant effect on the mRNA and protein expression levels of CYP7A1, while cholesterol sulfate administration significantly upregulated the mRNA and protein expression levels of CYP7A1 in mouse liver, suggesting that cholesterol sulfate may exert its cholesterol-lowering effect by promoting cholesterol metabolism to bile acids.
[0098] (2.8) Effects on cholesterol transport mRNA and protein in mice
[0099] like Figure 9 As shown, the results indicated that, compared with the control group, P407 modeling significantly downregulated the mRNA expression levels of ABCG5, SRB1, and LDLR in the liver, while having no significant effect on the mRNA expression level of LXR, suggesting that P407 prevents cholesterol from entering the liver from the bloodstream and reduces its excretion into bile. Compared with the P407 group, the positive control drug AVT downregulated the mRNA expression levels of ABCG5, SRB1, and LDLR in the liver and the LDLR protein level, suggesting that it promotes the entry of cholesterol from the bloodstream into the liver and increases its excretion into bile; cholesterol sulfate administration significantly upregulated the mRNA expression levels of ABCG5, SRB1, LDLR, and LXR in the liver and the LDLR protein level, suggesting that cholesterol sulfate may promote the entry of cholesterol from the bloodstream into the liver and increase its excretion into bile.
[0100] Example 2: Effects of cholesterol sulfate on mice with high-cholesterol diet-induced hypercholesterolemia
[0101] 1. Experimental Methods
[0102] Thirty SPF-grade male Kunming mice were randomly divided into a control group (N group, n = 6) and an experimental group. The model group was fed a high-cholesterol diet (73% basal diet, 20% fat, and 7% cholesterol) for 14 days to establish the high-cholesterol mouse model. On day 7, the mice were fasted for 12 hours but allowed free access to water. Serum TC, LDL-C, and HDL-C levels were measured. The high-cholesterol mouse model was established with serum TC ≥ 2.0 mmol / L and LDL-C ≥ 1.49 mmol / L. The experimental group was then randomly divided into four subgroups: the model group (HC, n = 6), the atorvastatin group (AVT group, n = 6), and the cholesterol sulfate group (low-dose group: cholesterol sulfate treatment dose of 150 mg / kg, n = 6) and the high-dose group (cholesterol sulfate treatment dose of 300 mg / kg, n = 6). Seven days after administration, daily weight changes were recorded. Mice were fasted for 12 hours but allowed free access to water. Serum TC, LDL-C, HDL-C, and TBA levels were measured by enucleation. TC and TBA levels in the liver and feces were also measured.
[0103] 2. Experimental Results
[0104] (2.1) Effects on cholesterol levels in mice
[0105] Experimental results are as follows Figure 10 As shown, compared with the normal group, the body weight, serum TC and LDL-C levels, and fecal TC levels of mice in the HC group were significantly increased. Compared with the HC group, both the AVT group and the cholesterol sulfate group reduced the body weight, serum TC and LDL-C levels, and liver TC levels of mice with high cholesterol. The cholesterol sulfate group increased fecal TC levels and promoted cholesterol excretion from feces. This suggests that cholesterol sulfate can significantly alleviate hypercholesterolemia induced by a high-cholesterol diet in mice.
[0106] (2.4) Effects on bile acid levels in mice
[0107] Experimental results are as follows Figure 11 As shown, compared with the normal group, the HC group had increased TBA levels in both serum and liver, but significantly decreased TBA levels in feces; suggesting that increasing the host's uptake of exogenous cholesterol can adaptively promote cholesterol bile acid metabolism, but reduce bile acid excretion. In mice fed a high-cholesterol diet, cholesterol sulfate significantly decreased serum TBA, upregulated liver TBA levels, and significantly increased fecal TBA content; suggesting that cholesterol sulfate can inhibit the reabsorption of bile acids and promote their excretion, thereby promoting the host's cholesterol metabolism into TBA.
[0108] Example 3: Effects of cholesterol sulfate on dexamethasone-fructose-induced hypercholesterolemia in mice
[0109] Sixty SPF-grade male SD rats were randomly divided into four groups: a control group (N group, n = 10), a model group (M group, n = 10), an atorvastatin group (AVT group, 10 mg / kg, n = 10), a low-dose cholesterol sulfate group (CHS-L group, 50 mg / kg, n = 10), a medium-dose cholesterol sulfate group (CHS-M group, 100 mg / kg, n = 10), and a high-dose cholesterol sulfate group (CHS-H group, 200 mg / kg, n = 10). The model group animals were intraperitoneally injected with dexamethasone (DEX, 250 μg / kg, once daily) and allowed free access to 30% fructose solution for 14 days to establish the model. The other groups received the corresponding medications once daily for 14 days simultaneously with model establishment. During the experiment, rat body weight, food intake, and water intake were measured and recorded daily, and serum TG and TC levels were measured weekly via blood collection from the orbital venous plexus. After the experiment, all animals were fasted but allowed free access to water for 12 hours. Serum TC, LDL-C, HDL-C, and TBA levels in rats were measured via blood collection from the abdominal aorta. Simultaneously, TC and TBA levels in the liver and feces were measured. The experimental results are as follows: Figure 12-15 As shown.
[0110] like Figure 12-13 As shown, compared with group N, group M rats showed significantly increased serum TC and LDL-C levels and liver TC levels; compared with group M, both AVT and CHS groups reduced serum TC and LDL-C levels and liver TC levels in rats; suggesting that cholesterol sulfate can significantly alleviate dexamethasone-fructose-induced hypercholesterolemia in mice.
[0111] like Figure 14 As shown, compared with the normal group, the M group had increased serum TBA levels, but significantly decreased TBA levels in the liver and feces; suggesting that dexamethasone and fructose can increase bile acid metabolism but simultaneously inhibit bile acid excretion. In dexamethasone-fructose-induced hypercholesterolemia rats, CHS administration significantly downregulated serum TBA levels and significantly upregulated fecal TBA levels, suggesting that cholesterol sulfate can inhibit bile acid reabsorption and promote its excretion, thereby reducing host cholesterol levels.
[0112] like Figure 15 As shown, compared with the normal group, the expression levels of CYP7A1, NTCP1 and BESP proteins in the liver of rats in group M were significantly reduced, while the level of ASBT protein in the small intestine was significantly increased. Compared with group M, group CHS significantly upregulated the levels of CYP7A1, NTCP1 and BESP proteins in the liver of rats and downregulated the level of ASBT protein in the small intestine, suggesting that cholesterol sulfate promotes cholesterol metabolism to bile acids and promotes bile acid excretion, thereby improving bile acid metabolism.
[0113] Example 4: Acute toxicity test of cholesterol sulfate
[0114] Experimental animals and methods:
[0115] The median lethal dose (LD50) of cholesterol sulfate was determined according to the People's Republic of China National Standard, "Chemicals: Acute Oral Toxicity Test Methods (GB / T21603–2008)". KM mice (provided by Guangdong Provincial Experimental Animal Center; hereinafter the same), SPF grade, weighing 20±2g, were randomly divided into six groups (n=10 per group, half male and half female). Mice in groups -1 to -5 were administered cholesterol sulfate via gavage at a single dose of 0.1mL / 10g body weight, with corresponding daily doses of 50.2 mg / kg, 162.0 mg / kg, 512.2 mg / kg, 1638.0 mg / kg, and 5243.6 mg / kg, respectively. The control group received an equal volume of 0.5% Tween 80.
[0116] After administration, mice had free access to food and water and were observed continuously for 14 days. Changes in body weight, food intake, and other daily living conditions, as well as mortality, were recorded every two days. Furthermore, within the first 12 hours after administration, toxic reactions, the number of deaths, and the time of death were observed and recorded every 3 hours in each group. After 12 hours of administration, these indicators were observed and recorded every 6 hours. The results are shown in Tables 1 and 2.
[0117] Table 1 Results of acute toxicity test of cholesterol sulfate in mice
[0118]
[0119] Table 2. Changes in body weight of mice in acute toxicity tests.
[0120]
[0121] The results are shown in Table 1-2. No obvious abnormalities or deaths were observed in any of the cholesterol sulfate dosage groups within 14 days. The results indicate that the maximum tolerated dose of cholesterol sulfate is greater than 5243.6 mg / kg, which is classified as a low-toxicity chemical.
[0122] Example 5: Preparation of water-soluble cholesterol sulfate hydroxypropyl-β-cyclodextrin inclusion complex
[0123] The method for preparing the water-soluble inclusion complex of the present invention includes the following steps:
[0124] S1. Add 95% ethanol to hydroxypropyl-β-cyclodextrin, heat to 50°C and stir until saturated to obtain solution A;
[0125] S2. Place solution A at 40℃~60℃ and stir magnetically. Slowly add cholesterol sulfate to carry out the inclusion reaction and obtain the inclusion solution.
[0126] S3. The inclusion solution obtained in step S2 is continuously magnetically stirred for 1-3 h, the ethanol is recovered, and the mixture is vacuum dried to obtain the water-soluble inclusion complex, which is called cholesterol sulfate hydroxypropyl-β-cyclodextrin inclusion complex.
[0127] In the above preparation conditions, the inclusion ratio of cholesterol sulfate to hydroxypropyl-β-cyclodextrin and the reaction conditions will affect the inclusion rate and the dissolution rate of cholesterol sulfate.
[0128] To optimize the preparation conditions, the present invention explored the following:
[0129] 1. Inclusion Ratio Investigation: The inclusion ratio of cholesterol sulfate to hydroxypropyl-β-cyclodextrin was determined by phase solubility method. Excess cholesterol sulfate was added to a series of different concentrations of hydroxypropyl-β-cyclodextrin, and the mixture was heated and stirred at 37℃ for 48 h. After complete stirring, the mixture was left at 37℃ for 12 h to reach dissolution equilibrium.

The concentration of cholesterol sulfate in the sample was calculated by high performance liquid chromatography (HPLC), and a phase solubility diagram was plotted.
[0130] 2. Preparation process optimization: In order to determine the optimal preparation conditions of cholesterol sulfate hydroxypropyl-β-cyclodextrin inclusion complex, based on the fixed amount of cholesterol sulfate (5 g) and solvent (1000 mL ethanol) and magnetic stirring at 600 r / min, the feed ratio, reaction temperature and reaction time were selected as factors to be investigated. The optimal preparation conditions of cyclodextrin inclusion complex of cholesterol sulfate were screened by orthogonal experiment, and a three-factor, three-level orthogonal experiment was designed. The orthogonal experimental design of L9(33) is shown in Table 3. The orthogonal experiment was carried out according to the factor level table (Table 4), and the results and range analysis are shown in Table 4.
[0131] 3. Result determination:
[0132] (3.1) Sulfuric acid cholesterol analysis method:
[0133] Chromatographic conditions: Column: Waters Atlantis C18 (300 mm × 4.6 mm); Mobile phase: Acetonitrile (A) and 0.77 g / L ammonium acetate (B); 0-20 min: 60% A; Flow rate: 1.0 mL / min; Detection wavelength: 210 nm; Injection volume: 10 μL.
[0134] (3.2) Since cholesterol sulfate is insoluble in water but readily soluble in methanol, and the cholesterol sulfate hydroxypropyl-β-cyclodextrin inclusion complex is soluble in both water and methanol, this invention calculates the inclusion rate of the inclusion complex by measuring the content of cholesterol sulfate dissolved in water and methanol.
[0135] Calculate the inclusion rate and yield according to Equations 1 and 2:
[0136] Inclusion rate = 1 - (Water-soluble cholesterol sulfate content / Total cholesterol sulfate content) × 100% — Equation 1
[0137] Yield = (mass of inclusion compound / total feed amount) × 100% — Equation 2
[0138] (3.3) Determination of cholesterol sulfate dissolution: 40 mg of cholesterol sulfate, cholesterol sulfate-hydroxypropyl-β-cyclodextrin inclusion complex, and a physical mixture (molar ratio 1:1, equivalent to 40 mg of cholesterol sulfate, both directly mixed in a mortar) were filled into gelatin capsules as samples for testing. The drug dissolution was tested according to Method II (paddle method) in Appendix 160 of the 2020 edition of the Pharmacopoeia of the People's Republic of China. The dissolution medium was 500 mL of artificial gastric fluid at a temperature of 37±0.3℃ and a rotation speed of 100 r / min. Quantitative samples of 1 mL were taken at 2 min, 5 min, 10 min, 15 min, 20 min, 30 min, 45 min, 60 min, 90 min, and 120 min, and an equal volume of the same temperature medium was added simultaneously. The samples were filtered through a 0.22 μm microporous membrane, and the content of cholesterol sulfate in the samples was detected by high performance liquid chromatography. The dissolution rate was calculated using the corresponding dissolution medium as a blank. This experiment was repeated 3 times, and the average value was taken.

[0144]
[0145] The phase solubility experiment results are as follows Figure 16 As shown, the obtained phase solubility curves exhibit good linearity (R² = 0.9958), indicating that cholesterol sulfate and hydroxypropyl-β-cyclodextrin molecules can bind in a 1:1 molar ratio. Table 4 shows the results of orthogonal experiments and range analysis, indicating that the factors influencing inclusion complex formation are, in order of importance, A > B > C. The optimal ratios are A1, B2, and C2. Therefore, the optimal preparation conditions for the cholesterol sulfate cyclodextrin inclusion complex are: a molar ratio of cholesterol sulfate to hydroxypropyl-β-cyclodextrin of 1:1, and a reaction temperature of 50℃ for 2 h. The average inclusion rate of the optimal product is 95.35 ± 1.77% (Table 5).
[0146] The dissolution curve of the obtained optimal product is as follows: Figure 17 As shown, cholesterol sulfate raw material is insoluble in simulated gastric fluid. At 120 min, the solubility of the cholesterol sulfate-hydroxypropyl-β-cyclodextrin physical mixture in simulated gastric and intestinal fluids was 14.03%. Compared to both the cholesterol sulfate raw material and the cholesterol sulfate-hydroxypropyl-β-cyclodextrin physical mixture, the cholesterol sulfate-hydroxypropyl-β-cyclodextrin inclusion complex achieved a solubility of nearly 73% in simulated gastric fluid at 45 min, indicating that the cholesterol sulfate-hydroxypropyl-β-cyclodextrin inclusion complex can significantly improve the solubility of cholesterol sulfate.
