Description:
FIELD OF THE INVENTION 
       [0001]    The present invention relates to a novel lupane triterpenoid derivatives and pharmaceutical use thereof, specifically relates to a lupane triterpenoid derivatives of formula (I)˜(III) and pharmaceutical use thereof, and further relates to a pharmaceutical composition and a combination preparation comprising a lupane triterpenoid derivatives or a pharmaceutically acceptable salt thereof in a therapeutically-effective dose, and the pharmaceutical use thereof, particularly relates to the uses in treatment of viral infection such as HIV-1/AIDS. 
       BACKGROUND OF THE INVENTION 
       [0002]    Currently no an effective vaccine or cure for HIV/AIDS, the only treatment option is to suppress viral replication with antiretroviral therapy on a lifelong basis. 
         [0003]    Although lots of drugs have been invented and used effectively to fight against HIV virus by employing a combinational use of nucleoside/nucleotide reverse transcriptase inhibitor, non-nucleoside reverse transcriptase inhibitors, and/or protease inhibitors, which are targeted at different stage of HIV virus life cycle, it has also brought out the side effects at same time. Among them, the most serious one is the multidrug-resistant viral strains evolved. Even with the new therapies available like fusion, entry, and integrase in recent years, the new resistant viral strains have also been reported both in vitro and in vivo. Therefore there is an urgent need to have a drug with a novel mechanism which may help to address increasing problems of current therapies. 
         [0004]    Maturation is an essential step in the life-cycle of HIV-1. It is the transition of the immature, non-infectious virus particle to the mature and infectious virion which represents as an excellent target for development of new class of anti-HIV-1 drugs. 
         [0005]    Some derivatives of lupane triterpenoid have been reported to have anti-HIV-1 activity, they bind to the preproteins (Gag) that specifically block HIV-1 protease to cleave p25 (CA-SPI) protein into their functional active form p24 (CA), resulting in the accumulation of the p25 (CA-SPI), immature and noninfectious HIV-1 virions that may prevent the subsequent cycles of HIV infection. These pharmacologically active lupane triterpenoid derivatives are called maturation inhibitors (MI), which represent a novel mechanism in fighting against HIV virus and may provide a new treatment for HIV with resistance to current therapies. Currently there is no such approval drug on the market based on this mechanism. 
         [0006]    Bevirimat (PA-457) is a new experimental agent to inhibit this last step of p25 (CA-SPI) protein being converted into the functional form p24 (CA). It has been reported that Bevirimat can reduce ART-resistant strains and wide type HIV viral load in patients, and has demonstrated synergy with antiretrovirals from all classes, but patients with Gag polymorphisms at Q369, V370, or T371 are resistant to this agent&#39;s therapy.

       Biological Assay 
       [0680]    The antiviral activity of the compounds of the present invention was determined in a HIV-1 full replication assay. 
         [0681]    In this assay, MT-2 cells that are infected with HIV-1 IIIB  were co-cultured with different concentration of the tested compounds for 3 days and then supernatant is transferred into new 384-well plates containing TZM-bl cells (also called JC53-bl). TZM-bl cells that could be infected by various kinds of HIV-1 strains stably express a great amount of HIV-1 receptor, co-receptor CD4 molecular, and co-receptor CXCR4 and CCR5. TZM-bl cells harbor LTR-luciferase and β-gal two report genes. The expression of luciferase and β-gal reporter directed by HIV-1 LTR can be activated by Tat protein generated after HIV infection, and the quantity of expression is proportional to the quantity of HIV-1. Compounds that interfere with virus replication in MT-2 cells, maturation of the virus, or post-entry steps in the HIV lifecycle decrease the luciferase signal or β-gal signal. In this experiment, BVM (Bevirimat, PA-457) is used as a positive control drug. 
         [0682]    Method for Inhibiting HIV-1 Replication Assay: 
         [0683]    1. Cell Culture 
         [0684]    The MT-2 cells are infected at a Multiciplicity (MOI) of 0.01 TCID50, and then the MT-2 cells suspension was diluted to a needed concentration. 90 μl of the MT-2 cells suspension from above was added into 384-well plates containing 10 μl of the tested compounds. 
         [0685]    2. Compound Preparation 
         [0686]    Compounds were dissolved in DMSO and tested as 11 points 3-fold serial dilutions. After addition of cells to compound plates, plates were placed to humidified 5% CO 2  37 incubator for 3 days. 10 μl of cells culture supernatant from the incubated plates was transferred into new black 384-well plates. 
         [0687]    3. Method for Compounds&#39; Cytotoxicity Assay: 
         [0688]    The MT-2 cells are diluted to a needed concentration. 90 μl of the MT-2 cells suspension was added into 384-well plates containing 10 μl of the tested compounds. Compounds were dissolved in DMSO and tested as 11 points 3-fold serial dilutions. After addition of cells to compound plates, plates were placed to humidified 5% CO2 37 incubator for 3 days. The Luciferase activity was measured by CellTiter-Glo® Luminescent Cell Viability Assay kit (Promega Corp., WI, USA). 
         [0689]    4. Method for Compounds&#39; Antiviral Activity Detection 
         [0690]    Adjusted the TZMb1 cells concentration and 40 μl of TZMb1 cells was added into each well in the black 384-well plates. After addition of the TZMb1 cells to the black plates, black plates were placed to humidified 5% CO 2  37 incubator for 24 h, then β-Gal activity was measured. 
         [0691]    Result Processing: 
         [0692]    The anti viral activity %=(measured number-lowest mean number)/(highest mean number-lowest mean number)×100. The IC 50  values were calculated by Median Equation and the IC curve was generated by Graphpad Prism V 5.03. 
         [0693]    TC 50  is referred to the toxicity in MT-2 cells by the compounds tested at 50% concentration; IC 50  is referred to the inhibiting HIV- 1IIIB  replication in MT-2 cells by the compounds tested at 50% concentration; Therapeutic Index (TI)=TC 50 /IC 50 . 
         [0694]    The IC 50  values of the example compounds tested in accordance with the HIV replication in MT-2 cell (HIV-1 IIIB ) assay are represented in table 1.
