Title: Method for the treatment of fatty liver disease

Description:
FIEDLD OF THE INVENTION 
     The present invention relates to a method for the treatment of fatty liver disease, and more particularly, to a method of administering a cyclohexenone compound. 
     BACKGROUND OF THE INVENTION 
     Fatty liver refers to a pathogenic condition where fat comprises more than 5% of the total weight of the liver. Fatty liver and steatohepatitis are frequently found in people who intake excessive alcohols and who have obesity, diabetes, hyperlipidemia, etc. Nonalcoholic fatty liver disease (NAFLD) refers to a wide spectrum of liver disease ranging from simple fatty liver (steatosis), to nonalcoholic steatohepatitis (NASH), to cirrhosis (irreversible, advanced scarring of the liver). All of the stages of NAFLD have in common the accumulation of fat (fatty infiltration) in the liver cells (hepatocytes). In NASH, the fat accumulation is associated with varying degrees of inflammation (hepatitis) and scarring (fibrosis) of the liver. The NAFLD spectrum is thought to begin with and progress from its simplest stage, called simple fatty liver (steatosis). That is, fatty liver is the initial abnormality in the spectrum of NAFLD. Simple fatty liver involves just the accumulation of fat in the liver cells with no inflammation or scarring. The fat is actually composed of a particular type of fat (triglyceride) that accumulates within the liver cells. Fatty liver is a harmless (benign) condition. The next stage and degree of severity in the NAFLD spectrum is NASH. As mentioned, NASH involves the accumulation of fat in the liver cells as well as inflammation of the liver. The inflammatory cells can destroy the liver cells (hepatocellular necrosis). In the terms “steatohepatitis” and “steatonecrosis”, steato refers to fatty infiltration, hepatitis refers to inflammation in the liver, and necrosis refers to destroyed liver cells. Strong evidence suggests that NASH, in contrast to simple fatty liver, is not a harmless condition. This means that NASH can ultimately lead to scarring of the liver (fibrosis) and then irreversible, advanced scarring (cirrhosis). Cirrhosis that is caused by NASH is the last and most severe stage in the NAFLD spectrum. 
     There are few therapeutically effective drugs for treating fatty liver. Exercise and controlled diet are recommended, but these are not so effective in treating fatty liver. 
     Accordingly, development of a fatty liver treatment having superior effect and safety with no adverse reactions is in need. 
     SUMMARY OF THE INVENTION 
     The invention provides a method of treating, inhibiting and/or preventing fatty liver disease in a patient in need thereof, comprising administering an effective amount of a cyclohexenone compound of the formula (I) as described herein to said patient.

     DETAILED DESCRIPTION OF THE INVENTION 
     In some embodiments, the invention surprisingly found that cyclohexenone compounds described herein effectively treat, inhibit and/or prevent fatty liver disease. 
     The terms “a” and “an” refer to one or to more than one (i.e., to at least one) of the grammatical object of the article. 
     The term “treat,” “treatment” or “treating” means reducing the frequency, extent, severity and/or duration with which symptoms of fatty liver disease are experienced by a patient. 
     The term “prevent,” “prevention” or “preventing” means inhibition, risk reduction, reducing the onset of or the averting of symptoms associated with fatty liver disease. 
     The term “pharmaceutically acceptable salt” refers to those salts which retain the biological effectiveness and properties of the free bases and which are obtained by reaction with inorganic or organic acids such as hydrochloric acid, hydrobromic acid, sulfuric acid, nitric acid, phosphoric acid, methanesulfonic acid, ethanesulfonic acid, p-toluenesulfonic acid, salicylic acid, malic acid, maleic acid, succinic acid, tartaric acid, citric acid, and the like. 
     The term “effective amount” means an amount of the compound described herein effective to treat, inhibit and/or prevent fatty liver diseases. For example, the effective amount of the compound described herein reduces the number of fat cells; reduces the liver size; inhibits (i.e., slow to some extent and preferably stop) fatty cell infiltration; inhibits (i.e., slows at least to some extent and preferably stops) inflammation (hepatitis), scarring (cirrhosis) or necrosis; and/or relieves to some extent one or more of the symptoms associated with the disease. 
     Plants and mushrooms are a valuable resource for the discovery and development of novel, naturally derived agents to treat cancer.  Antrodia camphorata  is also called Chang-Zhi, Niu Chang-Gu, red camphor mushroom and the like, which is a perennial mushroom belonging to the order  Aphyllophorales,  the family Polyporaceae. It is an endemic species in Taiwan growing on the inner rotten heart wood wall of  Cinnamomum kanehirae  Hay.  C. kanehirai  Hay is rarely distributed and being overcut unlawfully, which makes  A. camphorata  growing inside the tree in the wild became even rare. The price of  A. camphorata  is very expensive due to the extremely slow growth rate of natural A. camphorata that only grows between Junes to October. Traditionally,  A. camphorata  is used as a Chinese remedy for food, alcohol, and drug intoxication, diarrhea, abdominal pain, hypertension, skin itches, and liver cancer. Triterpenoids are the most studied component among the numerous compositions of  A. camphorata.    
     U.S. Pat. No. 7,385,088 is directed to a novel compound and use thereof, in particular to Antroquinonol B and Antroquinonol C isolated from  A. camphorata  extracts which effectively inhibit the growth of certain cancer cells. U.S. Pat. No. 7,342,137 provides cyclohexenone compounds and their uses in tumor growth inhibition, which is an extract isolated and purified from  A. camphorate,  in particular to 4-hydroxy-2,3-dimethoxy-6-methyl-5(3,7,11-trimethyl-dodeca-2,6,10-trienyl)-cyclohex-2-enone. Furthermore, several uses of the compound, 4-hydroxy-2,3-dimethoxy-6-methyl-5(3,7,11-trimethyl-dodeca-2,6,10-trienyl)-cyclohex-2-enone were developed. U.S. Pat. No. 7,411,003 discloses the use of 4-hydroxy-2,3-dimethoxy-6-methyl-5(3,7,11-trimethyl-dodeca-2,6,10-trienyl)-cyclohex-2-enone in inhibiting HBV. U.S. Pat. No. 7,456,225 discloses the use of 4-hydroxy-2,3-dimethoxy-6-methyl-5(3,7,11-trimethyl-dodeca-2,6,10-trienyl)-cyclohex-2-enone in liver protection such as alleviating liver injury and fibrosis induced by chemicals and reduces the serum levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST). U.S. Pat. No. 7,468,392 discloses the use of 4-hydroxy-2,3-dimethoxy-6-methyl-5(3,7,11-trimethyl-dodeca-2,6-10-trienyl)-cyclohex-2-enone in delaying fatigue. U.S. Pat. No. 7,501,454 relates to the use of 4-hydroxy-2,3-dimethoxy-6-methyl-5(3,7,11-trimethyl-dodeca-2,6,10-trienyl-)-cyclohex-2-enone in treating autoimmune diseases. US 8,236,860 provides the use of 4-hydroxy-2,3-dimethoxy-6-methyl-5-(3,7,11-trimethyl-dodeca-2,6,10-trienyl)-cyclohex-2-enone in inhibiting the survival of pancreatic cancer cells. US 20110060055, US 20110060056, US 20110060057, US 20110060058 and US 20110060059 disclose the use of 4-hydroxy-2,3-dimethoxy-6-methyl-5(3,7,11-trimethyl-dodeca-2,6,10-trienyl-)-cyclohex-2-enone in inhibiting the survival of lymphoma, gastric cancer, skin cancer, ovarian cancer and bladder cancer cells, respectively.

In some embodiments, the initial administration is made according to established protocols, and then, based upon the observed effects, the dosage, modes of administration and times of administration is modified by the skilled clinician. 
     In some embodiments, the compounds provided herein are administered by any convenient route, including oral, parenteral, subcutaneous, intravenous, intramuscular, intra peritoneal, or transdermal. The dosage administered depends upon the age, health, and weight of the recipient, kind of concurrent treatment, if any, and the nature of the effect desired. 
     In some embodiments, for administration, the compounds provided herein are mixed with one or more physiologically acceptable carriers comprising excipients and auxiliaries, which facilitate processing of the active compounds into preparations which are used pharmaceutically. Proper formulation is dependent upon the route of administration chosen. 
     In some embodiments, for oral administration, the compounds provided herein are formulated as discrete units such as capsules, cachets or tablets each containing a predetermined amount of the compound of the invention; as a powder or granules; as solution or a suspension in an aqueous liquid or a non-aqueous liquid; or as an oil-in-water liquid emulsion or a water-in-oil liquid emulsion. 
     In some embodiments, for injection, the compounds provided herein are formulated in aqueous solutions, preferably in physiologically compatible buffers such as Hank&#39;s solution, Ringer&#39;s solution, or physiological saline buffer. For transmucosal administration, penetrants appropriate to the barrier to be permeated are used in the formulation. Such penetrants, for example polyethylene glycol, are generally known in the art. In some embodiments, pharmaceutical compositions which are used orally, include push-fit capsules. 
     For administration by inhalation, the molecules for use according to the present invention are conveniently delivered in the form of an aerosol spray presentation from a pressurized pack or a nebulizer with the use of a suitable propellant, e.g., dichlorodifluoromethane, trichlorofluoromethane, dichloro-tetrafluoroethane or carbon dioxide. 
     In the case of a pressurized aerosol, the dosage unit is determined by providing a valve to deliver a metered amount in some embodiments. Capsules and cartridges of, e.g., gelatin for use in an inhaler or insufflator, is formulated containing a powder mix of the polypeptide and a suitable powder base such as lactose or starch in some embodiments. 
     The dose will be determined by the activity of the compound produced and the condition of the subject, as well as the body weight or surface area of the subject to be treated. The size of the dose and the dosing regiment also will be determined by the existence, nature, and extent of any adverse side effects that accompany the administration of a particular compound in a particular subject. In determining the effective amount of the compound to be administered, the physician needs to evaluate circulating plasma levels, toxicity, and progression of the disease. 
     EXAMPLE 
     Example 1: Isolation of Exemplary Cyclohexenone Compounds 
     100 g of mycelia, fruiting bodies or mixture of both from  A. camphorata  were placed into a flask. A proper amount of water and alcohol (70-100% alcohol solution) was added into the flask and were stirred at 20-25 degrees Celsius (° C.) for at least 1 hour. The solution was filtered through a filter and a 0.45 μm (micrometer) membrane and the filtrate was collected as the extract. The filtrate of  A. camphorata  was subjected to a High Performance Liquid chromatography (HPLC).

     Example 2: Reduction of Fatty Liver Condition by Compound 1 (4-hydroxy-2,3-dimethoxy-6-methyl-5(3,7,11-trimethyl-dodeca-2,6-10-trienyl)-cyclohex-2-enone) 
     In order to simulate an unhealthy diet tendency in humans, such as excess consumption of high caloric food, the example constructs an animal model using rats fed a high fat diet to evaluate the effects of chronic liver injury. Thereafter, the effects can be revealed through biochemical assays to prove the fatty liver reduction of exemplary compounds provided herein such as Compound 1, 4-hydroxy-2,3-dimethoxy-6-methyl-5(3,7,11-trimethyl-dodeca-2,6-10-trienyl)-cyclohex-2-enone (the test compound). 
     The assay simulates liver disease caused by a high fat diet through a “Metabolic Syndrome” model. That is, the model is different from conventional chemical induced models caused by toxic components such as CCl 4 . This model is distinguishable from the models caused by virus or alcohol. 
     The establishment of a long term high-fat diet is described as follows: First, the C57BL/6 mice were obtained from Charles River Laboratories Japan (Kanagawa, Japan). Animals were housed under specific-pathogen-free (SPF) conditions. The liver injury was developed in 18 male mice by subcutaneous injection of Streptozotocin (STZ) 2 days after birth (day 2). After 4 weeks, a high-fat commercial rodent diet ad libitum (CLEA JAPAN) were supplied. These mice were randomized into 3 groups before the treatment. The test compound was administered in a volume of 10 ml/kg twice a day for three weeks. In the control group (group A), six rats were fed with vehicle (corn oil from Sigma Chemical Co.) via intubation. Six mice in group B were orally administered vehicle and the test compound at a dose of 48 mg/kg twice a day (96 mg/kg per day). Table 1 summarizes the study timetable.

     Histology Analysis 
     (1) HE Staining. The HE staining method is performed as follows: Liver slices are cut from the livers&#39; left side, embedded in Tissue-Tek® OCT™ Compounds (Sakura Finetek, Japan), snap frozen in liquid nitrogen, and stored at −80° C. 5 μm sections are cut, air-dried, fixed in acetone, air dried again and finally washed with phosphate buffered saline (PBS). Then, in the hematoxylin and eosin staining method, liver sections will be prefixed in a Bouin solution (formalin-acetic acid) for one week and then stained with Lillie-Mayer&#39;s Hematoxylin (Muto Pure Chemicals, Japan) and eosin solution (Wako, Japan) to visualize the lipid deposition, inflammations, cell necrosis and fibrosis, or stained with Masson&#39;s trichromic solution to visualize extra cellular matrix and collagen fibers of liver fibrosis development. 
     (2) Sirius Red Staining. The Sirius Red staining method is performed as follows: Liver slices are cut from the livers&#39; left side, embedded in Tissue-Tek® OCT™ Compounds (Sakura Finetek, Japan), snap frozen in liquid nitrogen, and stored at −80° C. 5 μm sections are cut, air-dried, fixed in acetone, air dried again and finally washed with phosphate buffered saline (PBS). Then, liver sections are stained with a Picro-Sirius Red Solution (Waldeck GmbH &amp; KG, Germany) to observe collagen deposition. 
     (3) Immunohistochemistry of Collagen Type 3. The immunohistochemistry assay for collagen Type 3 is performed as follows: Liver slices are cut from the livers&#39; left side, embedded in Tissue-Tek® OCT™ Compounds (Sakura Finetek, Japan), snap frozen in liquid nitrogen, and stored at −80° C. 5 μm sections are cut, air-dried, fixed in acetone, air dried again and finally washed with phosphate buffered saline (PBS). For immunohistochemistry, endogenous peroxidase activity will be blocked by using 0.03% H 2 O 2  for 5 minutes, followed by incubation with Block Ace (Dainippon Sumitomo Pharm, Japan) for 10 minutes. The sections will be incubated with the optimal dilution of anti-Type 3 collagen antibody overnight at 4° C. After incubation with an appropriate secondary antibody, the substrate reactions are performed using DAB/H 2 0 2  solution (Nichirei, Japan). 
     Whole Blood and Plasma Biochemistry 
     (1) Whole Blood Glucose. Blood samples were collected in heparinized syringes (Novo-Heparin 5,000 units/5 ml, Mochida Pharmaceutical, Japan) by cardiac puncture, kept on ice and centrifuged at 1,000×g at 4° C. for 15 minutes. The supernatant was collected and stored at −80° C. until use. Blood glucose was measured in whole blood samples using G Checker (Sanko Junyaku Co. Ltd., Japan). 
     (2) Plasma Aspartate aminotransferase (AST) and Alanine aminotransferase (ALT). The detection of plasma AST and ALT are performed as follows: Blood samples were collected in heparinized syringes (Novo-Heparin 5,000 units/5 ml, Mochida Pharmaceutical, Japan) by cardiac puncture and kept on ice then centrifuged at 1,000×g at 4° C. for 15 minutes. The supernatant was collected and stored at −80° C. until use. AST, ALT levels were measured by FUJI DRY CHEM 7000 (Fuji Film, Japan). 
     Fatty Liver Disease Caused by Non-Chemical Injury 
       FIG. 1  to  FIG. 7  have proved that the exemplary compound extracted from  A. camphorata  (Compound 1) effectively decreases the extent of fatty liver disease caused by non-chemical injury. The decrease is assessed by evaluating the extent of liver injuries of fat deposition by histological analyses such as HE staining, Sirius red staining and collagen immunostaining, and further by plasma biochemical marker such as blood glucose, plasma triglyceride, plasma ALT and plasma AST. 
     HE staining reveals the morphology of hepatic cells under inflammatory cell infiltration, and macro- and micro- vesicular fat deposition.  FIG. 1 (A-D) shows the representative photomicrographs of HE-stained sections of livers of Group A and Group B, wherein  FIG. 1(A)  and 1(C) show an enlargement ratio of 50× and  FIGS. 1(B) and 1(D)  show an enlargement ratio of 200×. As shown in  FIGS. 1(A) and 1(B) , the Group A (vehicle) diagrams revealed infiltration of inflammatory cells, macro- and micro vesicular fat deposition, proliferated bile ducts and hepato-cellular ballooning in the liver sections. As shown in FIGS.  1 (C) and  1 (D), group B (the test compound, Compound 1) treatment tended to decrease the infiltration of inflammatory cells and also tended to decrease the macro-vesicular fat deposition compared to Group A. 
     Sirius Red Staining is utilized to detect collagen deposition.  FIG. 2  shows the representative photomicrographs of Sirius-red staining of livers of Group A and Group B, wherein  FIGS. 2(A) and 2(C)  show an enlargement ratio of 50× and  FIGS. 2(B) and 2(D)  show an enlargement ratio of 200×. As shown in  FIGS. 2(A) and 2(B) , in group A, Sirius red staining demonstrates collagen deposition around central veins, bile ducts and degenerative hepatocytes. As shown in  FIGS. 2(C) and 2(D) , in Group B (the test compound, Compound 1) treatment, the collagen deposition around the central veins and the bile ducts was reduced. 
     Collagen Type 3 staining is used to detect the distribution of collagen fibers.  FIG. 3  shows the representative photomicrographs of collagen Type 3-immunostained sections of livers of Group A and Group B, wherein  FIGS. 3(A) and 3(C)  show an enlargement ratio of 50× and  FIGS. 3(B) and 3(D)  show an enlargement ratio of 400×. As shown in  FIGS. 3(A) and 3(B) , Collagen Type 3 staining shows accumulation of collagen fibers in the sinusoidal area and around bile ducts and central veins in the Vehicle control group A. As shown in  FIGS. 3(C) and 3(D) , the Group B (the test compound, Compound 1) treatment tended to reduce the thickness and/or the length of the collagen fibers in the sinusoidal area. 
       FIG. 4  shows the diagram of the whole blood glucose concentration (mg/dL) of Group A and Group B. As shown in  FIG. 4 , Group B treatment (the test compound, Compound 1) showed a decrease in the whole blood glucose level compared to the results of Group A treatment (Group A: 636±137 mg/dL, Group B: 580±122 mg/dL). 
       FIG. 5  shows the diagram of the plasma triglyceride (TG) concentration (mg/dL) of Group A and Group B. As shown in  FIG. 5 , Group B treatment (the test compound, Compound 1) showed a significant decrease in the plasma TG compared to the results of Group A treatment (Group A: 643±402 mg/dL, Group B: 229±144 mg/dL). 
     The aspartate aminotransferase (AST) and the alanine aminotransferase (ALT) are important enzymes in the amino acid synthesis for the human organs such as liver, heart, muscles, etc. AST and ALT are commonly measured clinically as a part of a diagnostic evaluation of hepatocellular injury, to determine liver health. These enzymes&#39; content in serum is low under normal conditions. Significantly elevated levels of AST and ALT often suggest the existence of liver injury.  FIG. 6  and  FIG. 7  show diagrams of plasma AST and plasma ALT concentration (U/dL) for Group A and Group B, respectively. As shown in  FIG. 6 , Group B (the test compound, Compound 1) treatment seems to slightly reduce the plasma AST level compared to Group A (vehicle) treatment (Group A: 202±177 U/L, Group B: 141±35 U/L). As shown in  FIG. 7 , Group B (the test compound, Compound 1) treatment seems to slightly reduce the plasma ALT level compared to Group A (vehicle) treatment (Group A: 64±64 U/L, Group B: 34±10 U/L). 
     In summary, the test compound treatment decreased the plasma TG levels, tending to inhibit blood glucose levels, and slightly decreased the plasma AST and ALT. The test compound treatment also decreased the infiltration of inflammatory cells and fat deposition in the liver lobule. Moreover, the test compound tended to inhibit collagen deposition, shown in both Sirius red staining and collagen Type 3 staining, suggesting that the test compound has an anti-fibrotic effect on liver fibrosis steatohepatitis. 
     Fibrosis of Steatohepatitis Caused by Non-Chemical Injury 
       FIG. 8  to  FIG. 14  show that the test compound, Compound 1 effectively decrease fibrosis of steatohepatitis liver cells induced by non-chemical injury. The decrease is assessed by evaluating the extent of liver injuries in liver fibrosis by histological analyses such as HE staining, Sirius red staining and collagen immunostaining, and further by plasma biochemical marker such as blood glucose, plasma alanine aminotransferase and plasma aspartate aminotransferase. 
       FIG. 8  shows the representative photomicrographs of HE-stained sections of livers of Group A and Group B, wherein  FIGS. 8(A) and 8(C)  show an enlargement ratio of 50×, and  FIGS. 8(B) and 8(D)  show an enlargement ratio of 200×. As shown in  FIGS. 8(A) and 8(B) , the Group A (vehicle) diagrams reveal infiltration of inflammatory cells, macro- and micro vesicular fat deposition, proliferated bile ducts, and hepatocellular ballooning in the liver sections. As shown in  FIGS. 8(C) and 8(D) , group B (the test compound, Compound 1) treatment tended to decrease the macro-vesicular fat deposition compared to Group A. 
       FIG. 9  shows the representative photomicrographs of Sirius-red staining of livers of Group A and Group B, wherein  FIGS. 9(A) and 9(C)  show an enlargement ratio of 50×, and  FIGS. 9(B) and 9(D)  show an enlargement ratio of 200×. As shown in  FIGS. 9(A) and 9(B) , in Group A, Sirius red staining demonstrates collagen deposition around central veins, bile ducts and degenerative hepatocytes. In Group A treatment, central-to-central bridging fibrosis is observed, showing serious fibrosis in liver cells. As shown in  FIGS. 9(C) and 9(D) , in Group B (the test compound, Compound 1) treatment, the collagen deposition around the central veins and the bile ducts was reduced. 
       FIG. 10  shows the representative photomicrographs of collagen Type 3-immunostained sections of livers of Group A and Group B, wherein  FIGS. 10(A) and 10(C)  show an enlargement ratio of 50×, and  FIGS. 10(B) and 10(D)  show an enlargement ratio of 400×. As shown in  FIGS. 10(A) and 10(B) , Collagen Type 3 staining shows accumulation of collagen fibers in the sinusoidal area, and around bile ducts and central veins in the Vehicle control Group A. As shown in  FIGS. 10(C) and 10(D) , the Group B (the test compound, Compound 1) treatment tended to reduce the thickness and/or the length of the collagen fibers in the sinusoidal area. 
       FIG. 11  shows the diagram of the whole blood glucose concentration (mg/dL) of Group A and Group B. As shown in  FIG. 11 , Group B treatment (the test compound, Compound 1) showed a significant decrease in the whole blood glucose level compared to the results of Group A treatment (Group A: 728±109 mg/dL, Group B: 566±65 mg/dL). 
       FIG. 12  shows the diagram of the plasma triglyceride (TG) concentration (mg/dL) of Group A and Group B. As shown in  FIG. 12 , Group B treatment (the test compound, Compound 1) showed a slight decrease in the plasma TG compared to the results of Group A treatment (Group A: 758±877 mg/dL, Group B: 704±450 mg/dL). 
       FIG. 13  and  FIG. 14 , respectively show diagrams of plasma AST and plasma ALT concentration (U/dL) for Group A and Group B. In  FIG. 13 , Group B (the test compound, Compound 1) treatment slightly increase the plasma AST level compared to Group A (vehicle) treatment, but the change is not significant (Group A: 143±42 U/L, Group B: 167±87 U/L). As shown in  FIG. 14 , Group B (the test compound, Compound 1) treatment reduces the plasma ALT level compared to Group A (vehicle) treatment (Group A: 47±22 U/L, Group B: 38±11 U/L). 
     In summary, the treatment with the test compound (e.g., Compound 1) decreased the blood glucose levels, the plasma TG levels, and tends to decrease the fat deposition in the liver lobule and the ALT levels, suggesting that the cyclohexenone compounds provided herein have an ameliorating effect on lipid and carbohydrate metabolism and a protective effect on liver injury caused by a high-fat diet. Also, the exemplary cyclohexenone compound (e.g., Compound 1) tended to inhibit collagen deposition, shown in both Sims red staining and collagen Type 3 staining, showing that the cyclohexenone compounds provided herein have an anti-fibrotic effect on liver steatohepatitis. 
     Taken together, the present invention successfully demonstrated that the test compound treatment effectively decrease the extents of fatty liver disease and liver fibrosis induced by metabolic syndrome, especially from high-fat diet treatment.

     HE Staining 
       FIG. 15  shows the representative photomicrographs of HE-stained sections of livers from Group A to Group C, wherein  FIGS. 15(A), 15(C), 15(E)  show an enlargement ratio of 50× and  FIGS. 15(B), 15(D), 15(F)  show an enlargement ratio of 200×. As shown in  FIGS. 15(A) and 15(B) , the Group A figures revealed infiltration of inflammatory cells, macro- and micro vesicular fat deposition, proliferated bile ducts and hepatocellular ballooning in the liver sections. As shown in  FIGS. 15(C) and 15(D) , treatment with combination of the test compound (Compound 1) and ergosterol decreased the macro vesicular fat deposition and the infiltration of inflammatory cells. The number of mitotic figures in hepatocytes is higher in group B compared to the group A. As shown in  FIGS. 15(E) and 15(F) , the treatment with the test compound alone tended to decrease the macro vesicular fat deposition but did not affect the infiltration of inflammatory cells. 
     From  FIG. 15 , it is recognized that the treatment with the test compound (Compound 1) and ergosterol (Group B) have the ability of reducing the macro vesicular fat deposition. Compared to the treatment with the test compound alone (Group C), the treatment with the test compound and ergosterol (Group B) further inhibit the inflammatory cells infiltration, thereby showing better anti-inflammatory effects with respect to Group C. 
     Sirius Red Staining 
       FIG. 16  shows the representative photomicrographs of Sirius-red stained of livers from Group A to Group C, wherein  FIGS. 16(A), 16(C), 16(E)  show an enlargement ratio of 50× and  FIGS. 16(B), 16(D), 16(F)  show an enlargement ratio of 200×. As shown in  FIGS. 16(A) and 16(B) , in group A, Sirius red staining show collagen deposition around central veins, bile ducts and degenerative hepatocytes, showing central-to-central bridging fibrosis and indicating serious fibrosis steatohepatitis. As shown in  FIGS. 16(C) and 16(D) , the treatment with the combination of the test compound (Compound 1) and ergosterol tended to decrease the collagen deposition. As shown in  FIGS. 16(E) and 16(F) , the cyclohexenone alone treatment tended only slightly to decrease the collagen deposition compared to that in the control group. 
     In summary, both the treatments with the cyclohexeone compound provided herein (e.g., Compound 1) and ergosterol treatment (Group B) and the treatment with the test compound alone (Group C) tend to inhibit collagen deposition, and thus prevent liver fibrosis. More specifically, the treatment with the combination of the cyclohexenone compound provided herein (e.g., Compound 1) and ergosterol provides a better anti-liver-fibrosis ability compared to the treatment with the test compound alone. 
     Immunohistochemistry of Collagen Type 3 
       FIG. 17  shows the representative photomicrographs of collagen Type 3-immunostained sections of livers from Group A to Group C, wherein  FIGS. 17(A), 17(C), 17(E)  show an enlargement ratio of 100× and  FIGS. 17(B), 17(D), 17(F)  show an enlargement ratio of 400×. As shown in  FIGS. 17(A) and 17(B) , Collagen Type 3 staining shows accumulation of collagen fibers in the sinusoidal area and around bile ducts and central veins in the Vehicle control group. As shown in  FIGS. 17(C), 17(D), 17(E) and 17(F) , the combination of cyclohexenone (e.g., Compound 1) and ergosterol treatment and the cyclohexenone alone treatment tended to reduce the collagen deposition proved by the decrease of the thickness of the collagen fibers in the sinusoidal area, indicating their anti-fibrosis ability.
