Background technology:
Hepatitis B is hepatitis B virus (hepatitis B virus; HBV) cause, be to lead and cause a kind of communicable disease of multiple organ injury with the liver inflammatory lesion, wherein chronic viral hepatitis is the main diseases therefore that causes liver cirrhosis, liver cancer.According to The World Health Organization (WHO) statistics, the whole world has 2,000,000,000 people of surpassing to infect or is infecting HBV, and wherein about 400,000,000 people are HBV chronic infection person, the chronic hepatitis, liver cirrhosis and the primary hepatitis that have every year more than 100 ten thousand populations to die from hepatitis B to cause.China belongs to hepatitis B infected high popular district, and chronic viral hepatitis B cause of disease carrier surpasses 1.2 hundred million, about 2800-3000 ten thousand examples of chronic viral hepatitis B patient.Therefore the hepatitis B infection is serious world's public health problem, and the expense of treatment chronic hepatitis is very expensive, and every year, due to illness virus hepatitis caused direct economic loss to reach 30,000,000,000~50,000,000,000 Renminbi.
The course of infection of hepatitis B virus related generally to for 5 steps: combine, invade, transcribe, translation, gene replication and packing.At first virion is attached to liver cell through acceptor, sloughs adventitia behind the intrusion endochylema, forms core particle.Core particle moves to liver cell nuclear, HBV DNA core particle shelling and going out, in nucleus, form cccDNA (covalently closed circularDNA, cccDNA).CccDNA is the template of hepatitis B replication, is that liver cell continues infected key substance for a long time.CccDNA has 2 kinds of functions, the various members of the synthetic virion of the first, and like HBsAg (surface antigen constitutes adventitia), HBcAg (hepatitis virus c antigens, cAg constitute inner membrance), HBeAg (being secreted in the blood); It two is synthetic HBV DNA of future generation.Most of new synthetic HBV DNA is used for the packing of reovirion, and part then gets into liver cell nuclear again, becomes another source of cccDNA.The new synthetic HBV DNA of part at first is assembled into core particle with HBcAg, and then is assembled into complete HBV particle with HBsAg, discharges to the extracellular.Superfluous HBsAg is released into blood sometimes alone, forms microspheric form particle or cast particle.
Present multiple therapeutic modality comprises Hepatitis B virus vaccine, immunomodulator and anti-HBV medicine nucleoside analog etc., has been applied to treat HBV and has infected, and obtained certain curative effect.Hepatitis B virus vaccine can effectively prevent HBV to infect, yet invalid to the patient who infects HBV.Immunomodulator like alpha-interferon (IFN) etc., can show anti-HBV effect through improving body immunity, yet itself does not have antiviral activity.And Interferon, rabbit has tangible restraining factors at the treatment chronic hepatitis B: at first, it never obtains real success, only if the substantive immunoreation to HBV has appearred in patient before treatment.And spinoff is obvious, and before interferon-induced HBeAg serum conversion, hepatitis active unexpected one property crossed increases the weight of; Showing as ALT (alanine aminotransferase, ALT, alanine aminotransferase) raises; Can cause patient with liver cirrhosis generation liver failure, occur dead once in a while.Nucleoside medicine is a present internationally recognized curative effect anti-hepatic-B virus medicine preferably, all is nucleoside analog like lamivudine (lamivudine), adefovir ester (adefovir dipivoxiil), Entecavir (enticavir), Telbivudine (tibivudine), the tynofovir (tenofovir) that has gone on the market at present.During these medicines are tested, HBV virus there is remarkable restraining effect in external or body.Its mechanism of action is to become the triphosphoric acid compound in the medicine entering cell, through the competition of substrate, to the polysaccharase or the ThermoScript II inhibition of virus, finally suppresses synthetic, the viral propagation of viral DNA.The anti-HBV of nucleoside analog has characteristics such as evident in efficacy, easy administration, bioavailability is high, patient tolerability is good.Yet also have tangible weak point, single like action target spot, take for a long time and cause virus strain variation, produce resistance, can not thoroughly eradicate HBV, be prone to recurrence after the drug withdrawal.Present anti-HBV medicine far can not satisfy the needs that treatment HBV infects, so the Antihepatitis medicament that the development structure novelty has new role mechanism has very large market outlook.
China's traditional Chinese medicine aboundresources, medicinal history is long, and takes for a long time through human body and to show having determined curative effect, low toxicity or advantage such as nontoxic.Mile Swertia Herb is the peculiar anti-hepatitis Chinese medicine in Yunnan, is used to treat acute icterohepatitis for a long time among the people, have better curative effect, yet its anti-HBV active substance is still unclear.
So far; The report of no compound Herba Swertiae bimaculatae lactone H-K (shown in the formula I) in the prior art; Do not have its report yet, do not have Herba Swertiae bimaculatae lactone H-K and pharmaceutical composition thereof the application report in preparation or treatment hepatitis B medicine yet as the pharmaceutical composition of effective constituent.
