     BACKGROUND OF THE INVENTION 
       [0002]    1. Field of the Invention 
         [0003]    The present invention relates to compounds purified from  Antrodia camphorata , the methods for preparing the same and the use thereof; particularly the compounds inhibit proliferation of cancer cells and angiogenesis, and are utilized for treatment of cancer. 
         [0004]    2. Description of the Prior Art 
         [0005]      Antrodia camphorata  (originally named as  Antrodia cinnamomea ) is a Taiwanese endemic fungus growing in the hollow trunk of  Cinnamomum kanchirai Hayata , Lauraceae. In folk medicine,  Antrodia camphorata  is a useful antidote for the intoxication of food or pesticide; it is also used for treatment of hepatitis or other liver diseases. Regarding its high medical value, difficulty in culturing, and slow growth rate, several researches in genomics and metabolomics were published for further understanding about the medical use and culturing method of  Antrodia camphorata  (Lu et al. 2014 PNAS           Lin et al. 2011 J Agr Food Chem). 
         [0006]      Antrodia camphorata  comprises an amount of bioactive compound which is capable of medical use, including large molecule polysaccharide and small molecule terpenes. The polysaccharide consist of various monosaccharide units, most of which is 1,3-β-D-glucan, identified by spectrometry. It was reported that polysaccharides of  Antrodia camphorata  have diverse medical use, such as inhibiting angiogenesis (Yang et al. 2009 J Ethnopharmacol           Cheng et al. 2005 Life Sci), inhibiting immune response (Meng et al. 2012 Nutrition), modulating immune response and inhibiting asthma (Liu et al. 2010 Immunology), inhibiting hepatitis B (Lee et al. 2002 FEMS Microbiol Lett), inhibiting cancer cell proliferation (Liu et al. 2004 Toxicol Appl Pharmacol           Lee et al. 2014 Food Funct); also, it was reported that antrodan, a glycoprotein extracted from  Antrodia camphorata , provides hepatoprotective effect (Ker et al. 2014 PLoS ONE, TW500628, U.S. Pat. No. 7,763,723). 
         [0007]    Furthermore, triterpenoids is also a major group of medical compounds from  Antrodia camphorata . First of all, Cherng et al. reported  3  novel ergostane, a group of triterpenoid compounds: antcins A-C(Cherng et al. 1995 J Nat Prod), and other 4 novel triterpenoids compounds: antcins E-F           methyl antcinate G           methyl antcinate H(Cherng et al. 1996 Phytochemistry); following those reports, tens of triterpenoids compounds was reported to be applicable to therapeutic use, such as inhibition of cancer cell proliferation (Wu et al. 2010 J Nat Prod), inhibition of inflammation (Liaw et al. 2013 J Nat Prod), treatment of liver cancer and hepatitis (Lien et al. 2014 Molecules), anti-fatigue (Huang et al. 2012 Evid Based Complement Altern Med). 
         [0008]    U.S. Pat. No. 7,109,232 discloses  5  novel compounds purified from  Antrodia camphorata  and the use, including anti-inflammation and anti-cancer; U.S. Pat. No. 7,732,482 discloses that the said 5 compounds are effective in suppressing fibrosis of organisms. U.S. Pat. No. 7,342,137 discloses a novel group of compounds from  Antrodia camphorata , inhibiting various cancer cell lines. U.S. Pat. No. 7,745,647 demonstrates the novel diterpenes from fruiting body of  Antrodia camphorata  and their use as a neuroprotective agent. U.S. Pat. No. 7,994,158 provides the dehydrosulphurenic acid purified from  Antrodia camphorata  inhibits the proliferation of cancer, especially leukemia and pancreatic cancer; furthermore, U.S. Pat. No. 7,531,627 provides a 29 kDa novel protein ACA1 from  Antrodia camphorata , which enhances inflammation and has potential for treatment of cancer. 
         [0009]    The mechanisms by which  Antrodia  compounds inhibit cancer differ according to the chemical structure. Yeh et al. reported that sesquiterpene lactone antrocin suppresses JAK2/STAT3 signaling pathway and induces apoptosis (Yeh et al. 2013 Carcinogenesis); Yang et al. reports that  Antrodia  extract suppresses HER-2/neu pathway and inhibits ovarian cancer (Yang et al. 2013 J Ethnopharmacol); in addition, Wang et al. reported antroquinonol D cause DNA demethylation and has potential for treating cancer (Wang et al. 2014 J Agric Food Chem). 
         [0010]    In sum,  Antrodia camphorata  has an amount of substances having potential for treating cancers, some of which were proved to be effective against various cancers. However, little is known about if there are still other undiscovered novel compounds and its anticancer effect. Present invention extracts a number of compounds from  Antrodia camphorata , identifies their structures and investigates their effects on various diseases.

       Example 1 
     Preparation of the Active Substances from  Antrodia camphorata    
       [0054]    The mycelium media of  Antrodia camphorata  was extracted twice with reflux using hexane for 1-3 hrs each time and the two hexane extracts were combined after vacuum filtration. A column was prepared using silica gel (70-230 mesh) and mycelia and eluted with n-hexane/Ethyl acetate gradient solutions to obtain fraction F1, F2 and F3 and the corresponding gradient elution was 17-22% Ethyl acetate, 23-27% Ethyl acetate and 28-33% Ethyl acetate, respectively. The resulting fraction F3 was divided into F3-1˜F3-3 three fractions by retention time. 
         [0055]    Separate fraction F3-1 by silica gel column chromatography (from 50:1 to 20:1 gradient elution) using CH 2 Cl 2 /Acetone as the mobile phase and collect the fraction of 40:1-15:1 for further purification with a normal phase semi-preparative HPLC column and use n-Hexane/Ethyl acetate (4:1) to obtain purified AC006. 
         [0056]    Separate fraction F3-2 with a normal phase MPLC silica gel column and use CH 2 Cl 2 /Acetone gradient solutions (100%:0% to 70%:30%) as the mobile phase. Collect the fraction of 95%:5% to 85%:15% and divide into three fractions and further purify fraction F3-2-3 by silica gel column chromatography using n-hexane/Ethyl acetate (100%:0% to 0%:100%) as the mobile phase and collect the fraction of n-hexane/Acetone=90/10-70-30. Continue on purification by silica gel column chromatography using n-hexane/Ethyl acetate (100%:0% to 0%:100%) as the mobile phase and obtain AC007 with the elution solution of n-hexane/Ethyl acetate=60/40. 
         [0057]    Separate fraction F-3-3 with a normal phase MPLC silica gel column using CH 2 Cl 2 /Acetone (100%:0% to 0%100%) gradient elution and collect fractions from 90%:10% to 70%:30% which was then be divided into 5 fractions. Further purify F-3-3-5 (the fraction of CH 2 Cl 2 /Acetone=73/27) with a silica gel column using n-hexane/Acetone(95%:5% to 50%:50%) as the mobile phase. Collect the fractions from 85%:15% to 70%:30% and divide into 5 fractions. Take F3-3-5-1 (n-hexane/Acetone=90/10-80/20) for reverse phase MPLC C-18 column purification using 1% formic acid in H 2 O/methanol=35/6520/80 gradient as the mobile phase. Take the fraction of 1% formic acid in H 2 O/Methanol=28/72-22/78 for purification by silica gel column chromatography with n-hexane/Ethyl acetate as the mobile phase and gradient elution (80%:20% to 50%:50%) and obtain AC012 with the elution solution of n-hexane/Ethyl acetate (75%:25%-65%:35%). 
         [0058]    Separate F3-3-5-3 by reverse phase MPLC C-18 silica gel column chromatography and use 1% formic acid in H 2 O/Methanol=25/75 and isocratic elution with 15 ml per minute as the mobile phase to obtain the fraction containing most of AC009, and then further purify the fraction at 130-170 minutes of retention time with silica gel gradient solutions (100%:0% to 0%:100%) by using CH 2 Cl 2 /Ethyl acetate as the mobile phase and collect AC009 with the elution solution of CH 2 Cl 2 /Ethyl acetate=80/20-60/40. 
         [0059]    Take F3-1 and purify by reverse phase HPLC C-18 column chromatography using a mobile phase of 1% formic acid/methanol=25%:75% isocratic to obtain AC-05-01. 
         [0060]    Take fraction F3-3-5-4(n-hexane/Acetone=76/24) and purify by reverse phase HPLC C-18 column chromatography using 1% formic acid in H 2 O/Methanol=25%:75% and isocratic elution as the mobile phase to obtain AC011.

     Modification of Substituent of Compounds Purified from Mycelia of  Antrodia camphorata    
       [0075]    After identification of the chemical structure, the purified compounds were subsequently modified to substitute the substituent of C4 and C3. The method of modification is described in the following. The new compounds with hydroxyl group (—OH) on C4 are marked “H1”; the new compounds with hydroxyl group on C4 and additionally dimethoxy group on C3 are marked “H2” 
         [0076]    AC012 was hydrolyzed in 1 N (equivalent mole) of NaOMe (sodium methoxide) and anhydrous methanol, respectively. During the hydrolyzation, the reaction was monitored by TLC (thin layer chromatography) until the reaction had been completed. After completion, acidic amberlite was added to neutralize and then was filtered by filter membrane to obtain the intermediate product. 
         [0077]    The intermediate product was eluted by normal phase silica gel chromatography, using silica gel as separating resin, gradient of hexane and ethyl acetate as mobile phase, wherein the eluting gradient of hexane:ethyl acetate is from 4:1 to 1:1. As the process of elution was monitored by TLC, the mixture of products (AC012-H1 and AC012-H2) was eluted out at approximately 1:1 ratio of the gradient solution, and then was collected and condensed. 
         [0078]    The purification of respective product was performed by reverse phase HPLC, using C18 semi-preparative column and solution of methanol:0.1% FA buffer (phosphate buffered saline)=75:25 as isocratic eluant. The retention time to collect AC012-H1 was from 31 to 25 minutes; the retention time to collect AC012-H2 was from 39 to 43 minutes. 
         [0079]    The chemical structure of AC012-H1 and AC012-H2 are shown in the following:

         [0080]    The same modifying method in this example can be applied to other purified compounds in the present invention to render the similar substitution. 
         [0081]    If the initial input reactant was AC007, the retention time to collect AC007-H1 was from 36 to 43 minutes; AC007-H2, from 47 to 53 minutes. 
         [0082]    If the initial input reactant was AC009, the retention time to collect AC009-H1 was from 27 to 32 minutes; AC009-H2, from 35 to 40 minutes.

     Analysis of Anti-Angiogenic Activity of the Active Substances from Mycelia of  Antrodia camphorata    
       [0083]    SRB assay and matrigel capillary tube formation assay were performed to evaluate the anti-angiogenic effect of the purified compounds. 
         [0084]    SRB Assay 
         [0085]    Endothelial progenitor cell (EPCs, 5×10 3  cells/well) were sub-cultured onto 96-well plates and starved with serum-free medium for 48 h. Then cells were incubated in medium with 10% FBS in the absence or presence of various concentrations of AC012 (0.1, 0.3, 1, 3, 10 and 30 μg/ml) for 48 h. After treatment, the medium was discarded firstly. In order to fix the adherent cells, 100 μl of trichloroacetic acid (10% (w/v)) were adding to each well and incubating at 4° C. for 1 hour. Then the plates were then washed with deionized water and dried in the air. Each well were added with 50 μl of Sulforhodamine B (SRB) solution (0.4% w/v in 1% acetic acid) and incubated for 5 min at room temperature. To remove unbound SRB in the plates, the plates were washed with 1% acetic acid and then air dried. The residual bound SRB was solubilized with 100 μl of 10 mM Tris base buffer (pH 10.5), and then read using a micro titer plate reader at 495 nm. 
         [0086]    Matrigel Capillary Tube Formation 
         [0087]    Matrigel was added to 15-well-plates (ibidi) in a total volume of 10 μl in each well. Plates were stood at 37° C. for 30 min to form a gel layer. After gel formation, EPCs (5×10 3  cells) treated with or without AC012 (0.1, 0.3, 1 μg/ml) in presence of VEGF (20 ng/ml) were applied to each well, and plates were incubated for at 37° C. 16 hr with 5% CO 2 . After incubation, the inverted contrast phase microscope (Nikon, Japan) was used for subject observation. 
         [0088]    The inhibitory concentrations of 50% EPC cell proliferation (IC 50 ) was 29 μg/ml. In 1 μg/ml concentration, AC012 was able to inhibit 31.89% tube formation.

         [0090]    The purpose of the in vitro experiment is to evaluate the effect of AC006, AC007, AC009, AC011 and AC012 on cell proliferation in various cell lines. 
         [0091]    Various cell lines (5×10 3  cells/well) were sub-cultured onto 96-well plates and starved with serum-free medium for 48 h. Then cells were incubated in medium with 10% FBS in the absence or presence of various concentrations of AC006, AC007, AC009, and AC012 (0.1, 0.3, 1, 3, 10, and 30 μg/ml) for 48 hours. After treatment, the medium was discarded firstly. After treatment, the medium was discarded firstly.

         [0097]    In present invention, the bioactive compounds were purified to definite constituent and were shown to have inhibitory effects on angiogenesis at very low concentrations. Such compound not only can be purified from  Antrodia camphorata  mycelium by liquid fermentation, but also can be produced through chemical synthesis. This novel process can significantly reduce the cost of preparation and solve the issue of high demand for scarce  Antrodia camphorata . The present invention provides a novel application of bioactive substances which are to be used as drugs through its anti-angiogenesis activity and anti-proliferative on highly proliferating cells, i.e. cancer cells. Furthermore, by modifying the substituent, the bioactive compounds display more effective properties of anti-proliferation and anticancer. According to the result of examples, AC012-H1 shows extraordinary effectiveness against colorectal cancer cell, the proliferation of which was significantly inhibited by AC012-H1, implying that the modification of substituent is successful in enhancing the efficacy against cancer cells, especially colorectal cancer cells, wherein the feature of HCT116 cell line is low expression of Bax (Wang et al. 2012), growth factor (TGFα and EGFR)-independent (Howell et al. 1998). Additionally, some compounds show excellent effectiveness against the proliferation of liver cancer cell, specifically, Huh-7, epithelial-like tumorigenic cells derived from an Asian, carrying a HFE mutation (Vecchi et al. 2009). 
         [0098]    In summary, present invention presents an original approach for extraction of bioactive compounds and further identified their multifunctional properties in terms of anti-angiogenesis and anti-proliferation.
