Description:
TECHNICAL FIELD 
       [0001]    The present invention relates to the pharmaceutical field, in particular to a phenanthridine derivative, a pharmaceutical composition comprising the derivative, its preparation method, and its uses in manufacture of a medicament for prevention or treatment of a disease related to the activity of Wnt signaling pathway, hepatitis C and hepatitis B. 
       BACKGROUND 
       [0002]    World Health Organization estimates that there are about 2 billion patients infected with hepatitis B virus in the world, and 0.35-0.4 billion of them are chronic patients infected with HBV. Deaths due to acute or chronic HBV infection have reached 113.13 million every year and are increasing. There are a large number of hepatitis B patients in China and account for one-third of the number of chronic patients infected with HBV of the world, wherein, there are 0.12 billion hepatitis B carriers. Data shows that infection of hepatitis B virus has become a major disease endangering human health, therefore, an anti-HBV therapy effective in patients infected with HBV is particularly in urgent need worldwide, especially in China. In studies about treatment of HBV infection at home and abroad, it is considered that, persistent infection of HBV is the main reason for hepatitis B chronicity, and may lead to progression and deterioration of the disease into cirrhosis or HBV related hepatocellular carcinoma. Therefore, inhibition of HBV replication is the key to the treatment of chronic hepatitis B. At present, main drugs used for treatment of hepatitis B clinically can mainly be divided, according to their structures, sources and functions, into interferons, nucleosides, immunomodulators and natural herbs. 
         [0003]    Hepatitis C virus (HCV) is a major cause for chronic liver diseases. There is no vaccine used for preventing HCV infection. The combination of long-term PEG IFN-α and Ribavirin (RBV) is the best drug used for treatment of hepatitis C in recent 10 years, but more than 50% of patents infected with type I HCV failed to respond to such combinational antiviral therapy. Moreover, IFN and RBV have great toxic and side effects and the course of treatment is up to 1 year, which greatly limite its clinical use. Meanwhile, some anti-HCV medicaments inhibiting protease NS3/NS5 are also in clinical trials in recent years. 
         [0004]    Wnt signaling pathways are highly evolutionarily conserved in organism and regulate many life courses. During early development of animals, Wnt signaling is responsible for a series of important events such as ventral axis formation, blastoderm establishment, somite differentiation, tissue or organ formation, and directly controls cell fates such as proliferation, differentiation, polarization, apoptosis and anti-apoptosis. More than 10 members of the Wnt proteins are involved in various signal transduction pathways via interacting with different receptors on cell membrane. These pathways are divided into classical Wnt signaling pathway depending on β-catenin/TCF transcription complex (Wnt/β-catenin pathway) and non-classical Wnt signaling pathway independing on β-catenin/TCF transcription complex (Wnt/Ca 2+  pathway and Wnt/JNK pathway). 
         [0005]    Because Wnt/β-catenin signaling pathway is associated with many cancers and diseases, regulation of uncontrolled Wnt/β-catenin signaling pathway can be an excellent means for treating diseases related to Wnt/β-catenin signaling pathway. For example, the pathologic process of Alzheimer&#39;s disease is accompanied by abnormal inactivation of Wnt/β-catenin signaling pathway. Presenilin associated closely with Alzheimer&#39;s disease can form a complex with β-catenin and GSK3. Hence, molecular targeted therapies directed to the signaling pathways are expected to be a new and effective way for treatment of related diseases. In addition, Wnt signaling pathway also functions in maintaining pluripotency of stem cells, so adjustments of the signaling pathway are expected to be a new and effective way for application of stem cells. 
         [0006]    Therefore, it is in urgent need to develop new drugs for treatment of hepatitis B, hepatitis C, and diseases associated with activity of Wnt signaling pathway.

         [0185]    100 μL of Huh7.5 cells (1×10 5 /ml) was inoculated in 96-wells plates and incubated in an incubator at 37° C. under 5% of CO 2  and saturated humidity for 24 hrs. Then different concentration of the compound of the present invention and positive control (VX-950, telaprevir) were added respectively and incubated for a further 72 hrs. 10 μL of MTT (5 mg/mL) was added per well and incubated for another 4 hrs. After the cells were lysed with DMSO, OD 570-630 mm  was determined on ELIASA. In comparison with OD of the control group, inhibitory rate of each concentration on cell toxicity was calculated, and half toxic concentration of the compound was calculated with Reed-Muench method. 
         [0186]    (2) Anti-HCV Activity of the Compound in Cells: 
         [0187]    100 μL of Huh7.5 cells (1×10 5 /ml) was inoculated in 96-well plates and incubated in a incubator at 37° C. under 5% of CO 2  and saturated humidity for 24 hrs. Then Huh7.5 cells were infected with virus containing recombinant whole-genome HCV virus particles (Zong-Gen Peng, Bo Fan, Na-Na Du, et al. Small Molecular Compounds that Inhibit Hepatitis C Virus Replication Through Destabilizing Heat Shock Cognate 70 Messenger RNA. HEPATOLOGY, Vol. 52, No. 3, 2010, 845-853.), meanwhile, the compound of the present invention with different concentration and positive control (VX-950, telaprevir) were added respectively and incubated for a further 72 hrs. The total RNA was extracted from the cells. The intracellular content of HCV and RNA of internal control gene GAPDH were determined by real-time fluorescence qRT-PCR. In comparison with the viral RNA levels of the control group, the inhibition rate on HCV of each concentration was calculated with relative quantification method (1-2 ΔΔCT ), and half effective concentration of the compound on HCV inhibition was calculated by Reed-Muench method.

       Example 4 
       [0189]    The activity of compounds 10q, 10r, 11q, and 11r of the present invention on Wnt signaling pathway activation: 
         [0190]    Activity Assay of the Reporter Gene 
         [0191]    HEK293T, HCT116, SW480 or NIH3T3 cells used for activity assay of the reporter gene were inoculated into 24-wells plates respectively 24 hours before transfection then transfected following the above mentioned reference method. The amount of the plasmids used for Transfection was: 20 ng of TOPFlash, NFAT-Luc, or SRF-Luc, and 25 ng of EGFP-C1 (HEK293T); 25 ng of LEF-Luc, 75 ng of LEF1, and 25 ng of EGFP-C1 (NIH3T3); 100 ng of TOPFlash or Fopfllash and 100 ng of EGFP-C1 (HCT116 and SW480). The cells were transfected with other plasmids following experimental requirements, LacZs were added to meet a total content of 250 ng (in RNAi and plasmid co-transfection experiments, 1 μl of siRNA was added when every 100 ng/well of the plasmid was transfected). Wnt3a conditioned medium was added 18 hours after transfection to stimulate the cells for 6-8 hours, the cells were lysed using Boehringer Mannheim Luci-ferase Assay Kit (200 μl/well). Intensity of GFP proteins in cell lysates were determined as internal standards of expression quantity of the cells using fluorescence meter FL600 (BIO-TEK Inc. Winooski, Vt.), and then 20 μl of luciferase substrates were added. Luciferase activity was determined with Micro Lumate Plus (Perkin Elmer Inc. Wellesley, Mass.) luminometer. Finally, the luciferase activity was homogenized using activity of GFP. 
         [0192]    Determination of Intracellular Free β-Catenin 
         [0193]    HEK293T cells (in 6-wells plate) were stimulated with Wnt3a conditioned medium for 4 hours and collected into EP tubes using pre-cooled PBS, the tubes were centrifuged at 4° C. 3000 rpm for 5 min to remove PBS. The cells were suspended using hypotonic buffer (10 mM HEPES-KOH, pH 7.9, 1.5 mM MgCl 2 , 1 mM EDTA, 10 mM KCl, supplemented with protease inhibitors, NaF and Na 3 VO 4  before use) and placed on ice for 10 minutes and aspirated 6-8 times using insulin needles. The suspensions were centrifugated at 3000 rpm for 5 minutes, the obtained supernatants were ultracentrifugated at 100000 g, 4° C. for 1 hour, and the resultant supernatants were used for preparing cytoplasm samples. The precipitate obtained from centrifugation under 3000 rpm for 5 minutes were rinsed 3 times using hypotonic buffer and centrifuged at 4° C., 3000 rpm for 5 min to remove the hypotonic buffer, then suspended by hypertonic buffer (20 mM HEPES, pH7.9, 1.5 mMMgCl 2 , 420 mM NaCl, 0.2 mMEDTA, 10 mMNaF, 2 mMNa 3 VO 4 , 1 mM pyrophosphoric acid, supplemented with protease inhibitors, NaF, and Na 3 VO 4  before use) and ultracentrifugated at 100000 g, 4° C. for 1 hour after placed on ice for 30 min, and the resultant supernatants were used for preparing nucleus samples. After SDS-PAGE gel electrophoresis, a Western blot was performed by using specific antibodies aganist β-catenin, and free β-catenins in the cytoplasm samples and the nucleus samples were determined.
