Invention field

The present invention relates to a kind of single chain deoxynucleotide and ribavirin of the CpG of containing dinucleotides, particularly relate to the single chain deoxynucleotide and the ribavirin combined utilization that contain the CpG dinucleotides, can be used for the treatment and the prevention of virus infection and virus infection relative disease when single chain deoxynucleotide that contains the CpG dinucleotides involved in the present invention and ribavirin combined utilization.The virus of indication of the present invention includes but not limited to influenza virus, foot and mouth disease virus, dengue fever virus, japanese encephalitis virus, hepatitis C virus, hepatitis B virus, Human Immunodeficiency Virus and papilloma virus.The present invention also provides the sequence of the single chain deoxynucleotide that contains the CpG dinucleotides.

Background of invention

CpG ODN is the deoxy-oligonucleotide single stranded DNA of containing of synthetic of one or more CpG dinucleotides, CpG wherein is the dinucleotides that is connected into by phosphoric acid by cytosine(Cyt) and guanine, and C represents cytosine(Cyt), and G represents guanine, p represents phosphoric acid, and cytosine(Cyt) is positioned at 5 ' end.Because sequence is the difference of the sequence of CpG both sides especially, CpG ODN can have diversified form.Some CpG ODN has clear and definite immunoregulation effect, shows clinical value (Weiner GJ.The immunobiology and clinical potential of immunostimulatory CpGoligodeoxynucleotides.J Leukoc Biol 2000 Oct preferably; 68 (4): 455-63).The effect of some CpG ODN has species specificity, promptly a kind of animal is showed the CpG ODN of biological action, then may not show biologic activity (the Gunther Hartmann of same property or intensity another kind of animal, et al.Delineation of a CpGPhosphorothioate Oligodeoxynucleotide for Activating Primate Immune ResponsesIn Vitro and In Vivol The Journal of Immunology, 2000,164:1617-1624).

According to the characteristics of function, CpG ODN is divided into three types: A type CpG ODN (CpG-A ODN), Type B CpG ODN (CpG-B ODN) and C type CpG ODN (CpG-C ODN).Mainly show as the CpG ODN that activates dendritic cell, natural killer cell, stimulation dendritic cell secretion interferon activity and be classified as A type CpG ODN.A type CpG ODN is supposed to be used for tumour, disease of viral infection and other treatment of diseases with interferon therapy.Mainly show as the activation bone-marrow-derived lymphocyte, strengthen the active CpG ODN of humoral immunoresponse(HI) and be classified as Type B CpG ODN.Type B CpG ODN is the molecule adjuvant, can strengthen the immune effect of vaccine.Have both the main active CpGODN of A type CpG ODN and Type B CpG ODN and be classified as C type CpG ODN.

Experiment shows that CpG ODN has antiviral biologic activity.Transvaginal is used CpG ODN can make mouse or cavy improve ability (the Richard B.Pyles et al.Use ofImmunostimulatory sequence-Containing Oligonucleotides as Topical Therapy forGenital Herpes Simplex Virus Type 2 Infection.Journal of Virology of opposing II herpes simplex virus type (HSV-2), November 2002, Vol.76, No.22 are p.11387-11396).Use lotus amount (the Cho JY that CpG ODN can reduce its respiratory syncytial virus (RSV) to mouse, et al.Immunostimulatory DNA sequences inhibit respiratorysyncytiai viral load, airway inflammation, and mucus secretion.J Allergy ClinImmunol 2001 Nov; 108 (5): 697-702).The mouse of injection CpG ODN is after the HSV-2 through lethal quantity attacks, virus titer obviously reduces (Harandi AM in the vaginal secretions, Eriksson K, Holmgren J.A protectiverole of locally administered immunostimulatory CpG oligodeoxynucleotide in amouse model of genital herpes infection.J Virol 2003 Jan; 77 (2): 953-62).

Ribavirin (1-β-D-ribofuranosyl-1,2,4-triazole-3-carboxamide, Ribavirin), also claim Virazole, it is a kind of nucleoside analog, antiviral activity (Gilbert with wide spectrum, B Eand Knight V.Biochemistry and clinical applications of ribavirin.Antimicrob.Agents Chemother.1986,30 (2): 201-205) (Streeter DG, Witkowski JT, Khare GP, Sidwell RW, Bauer RJ, Robins RK, Simon LN.Mechanism of action of 1--D-ribofuranosyl-1,2,4-triazole-3-carboxamide (Virazole), a newbroad-spectrum antiviral agent.Proc Natl Acad Sci U S is Apr A.1973; 70 (4): 1174-8.), be used to the treatment (Gilbert of multiple disease of viral infection, B E and Knight V.Biochemistry andclinical applications of ribavirin.Antimicrob.Agents Chemother.1986,30 (2): 201-205).Ribavirin and interferon-alpha combined utilization are to treat effective ways (the Davis GL of the chronic hepatitis C that is caused by infection with hepatitis C virus, Esteban-Mur R, Rustgi V, Hoefs J, Gordon SC, TrepoC, Shiffman ML, Zeuzem S, Craxi A, Ling MH, Albrecht J.Interferon alfa-2b aloneor in combination with ribavirin for the treatment of relapse of chronic hepatitisC.International Hepatitis Interventional Therapy Group N Engl J Med.1998 Nov19；339(21)：1493-9.)。Ribavirin and long-acting interferon-alpha (pegylated interferon, peginterferon) combined utilization has tangible curative effect (Torriani FJ, Rodriguez-Torres M to the treatment hepatitis C, RockstrohJK, Lissen E, Gonzalez-Garcia J, Lazzarin A, Carosi G, Sasadeusz J, Katlama C, Montaner J, Sette H Jr, Passe S, De Pamphilis J, Duff F, Schrenk UM, DieterichDT; APRICOT Study Group.Peginterferon Alfa-2a plus ribavirin for chronichepatitis C virus infection in HIV-infected patients.N Engl J Med.2004 Jul 29; 351 (5): 438-50).

Influenza virus is the pathogenic agent that causes human influenza.At 1918-1919, the whole world has 20,000,000 people to die from popular (Patterson, the K.D.﹠amp of influenza virus; Pyle, G.F. (1991) Bull.Hist.Med.65,4-213).Vaccination and application antiviral are two class main method (Bridges, C.B., Fukuda, K., Cox, the N.J.﹠amp of control influenza virus; Singleton, J.A. (2001) Morbid.Mortal.Wkly.Rep.50 1-44), but fact proved, these two class methods all can not be controlled popular (Webby, the R.J.﹠amp of influenza effectively; Webster, R.G. (2001) Philos.Trans.R.Soc.London 356,1817-1828).In Susceptible population, vaccinated short-term (half a year) protection ratio is about 39% (Fukuda, K., N.J. (1999) Morbid.Mortal.Wkly.Rep.48,1-28, Castle, S.C.Clinical relevance of age-related immune dysfunction.ClinInfect Dis.2000 Aug; 31 (2): 578-85.Epub 2000 Sep 14.Review).Because the continuous variation of influenza antigen [hemagglutinin (HA) and Sialidase (NA)] property, existing vaccine almost all will be reconstructed structure every year again.Because the bigger and new anti-medicine strains of influenza viruses of side effect constantly occurs, the effect of the anti-influenza virus medicament that some get the Green Light also undesirable (Luscher-Mattli, M.Influenza chemotherapy:a review of thepresent state of art and of new drugs in development.Arch Virol.2000; 145 (11): 2233-48.Review.).

Hepatitis C virus (HCV) is the pathogenic agent that causes hepatitis C, has infected about more than 100,000,000 seven thousand ten thousand people in the whole world.Liver cancer and liver cirrhosis are that HCV infects two severe complications that cause.Worldwide, adopting alpha-interferon and ribavirin combined utilization is the method for treatment infection with hepatitis C virus, its efficient 40%[Jon Cohen.Science, 1999,285:26-30 of being about].Hepatitis C virus is a kind of tunicary sub-thread positive chain RNA virus, belongs to flaviviridae.Other two kinds of viruses of flaviviridae, dengue fever virus (Wang WK, Lin SR, Lee CM, King CC, Chang SC.Dengue type 3 virus in plasma is a population of closely related genomes:quasispecies.J Virol.2002 May; 76 (9): 4662-5.) and japanese encephalitis virus (Yun SI, Kim SY, Rice CM, Lee YM.Development and application of a reverse genetics system forJapanese encephalitis virus.J Virol.2003 Jun; 77 (11): 6450-65.).Dengue fever virus, japanese encephalitis virus also are the RNA viruses of sub-thread normal chain.Owing to still do not have the cell and the animal model of research hepatitis C virus, the result who adopts dengue fever virus, japanese encephalitis virus to do the experiment acquisition can represent on suitable degree with hepatitis C virus and be the result that the cell experiment obtains.

(foot-and-mouthdisease FMD) is the deadly infectious disease that is caused by foot and mouth disease virus to foot and mouth disease.Pig, ox, sheep all can infect foot and mouth disease virus and foot and mouth disease takes place, and pathologies such as bubble, ulceration and speck appear in the lighter at positions such as mouth, tongue, lip, hoof, breast, and death takes place weight person.The generation of foot and mouth disease and popular meeting cause huge direct and indirect financial loss [Jiang Pengfei, Zhao Qizu, Xie Qingge, foot and mouth disease progress Scientia Agricultura Sinica 1999,32 (6): 93～100].International Office of Epizootics (OIE) classifies foot and mouth disease as the category-A livestock contagious disease.Countries in the world are all attached great importance to prevention and control foot and mouth disease.Except that massacring the domestic animal that infects foot and mouth disease, vaccination is the major measure [M.Woolhouse, 2001] of prevention and control foot and mouth disease.Traditional aftosa vaccine refuels the deactivation vaccine that adjuvant emulsion makes by the foot and mouth disease virus of the preliminary purification of deactivation, and the susceptible domestic animal is had suitable provide protection, but exists deactivation insufficient and cause the possibility of foot and mouth disease.In addition, the great-hearted foot and mouth disease virus of employing in producing this vaccine process is a kind of very important potential contagium.

Twentieth century is since the beginning of the eighties, and many countries have dropped into a large amount of human and material resources and financial resources are developed novel aftosa vaccine, as recombinant protein vaccine, and synthetic peptide vaccine, [Broekhuigsen M P, 1987 such as live vector vaccine and D N A vaccine; Morgan D O, 1990; Ward, G., Rieder, E.﹠amp; Mason, P.W.Plasmid DNA encodingreplicating foot-and-mouth disease virus genomes induces antiviral immuneresponses in swine.Journal of Virology 1997,71,7442-7447.; Berinstein A, TamiC, Taboga O, Smitsaart E, Carrillo E.Protective immunity against foot-and-mouthdisease virus induced by a recombinant vaccinia virus.Vaccine.2000 Apr28; 18 (21): 2231-8.].Some vaccines have shown effect preferably, but major part is still among breadboard exploration.

Foot and mouth disease virus (foot-and-mouth disease virus, FMDV) be the pathogenic agent of foot and mouth disease, be the member of Picornaviridae (Picornaviridae) Hostis (Aphthovirus), 7 serotypes have been had now found that, be O, A, C type (title Europe class), SAT1, SAT2, SAT3 type (South Africa 1,2,3 types also claim African type) and AsiaI type (the Asia I type claims Asian type).O type foot and mouth disease virus is a popular wider serotype in the world wide in recent years.Studies show that, at humoral immunization in the human body foot-and-mouth disease virus resistant infects, play a major role.Be in the carcass, the ability that the level of foot and mouth disease virus neutralizing antibody and its opposing foot and mouth disease virus are attacked is tangible positive correlation [Pay TW, Hingley PJ.Correlation of 140S antigen dose with the serum neutralizing antibody responseand the level of protection induced in cattle by foot-and-mouth diseasevaccines.Vaccine.1987 Mar; 5 (1): 60-4.].Based on this observation, a large amount of experiments have been done in many laboratories, on foot and mouth disease virus, seek the target spot that can stimulate body to produce virucidin, there is structure [the Crowther JR of five candidates in discovery in the coat protein (VP) of foot and mouth disease virus, Farias S, Carpenter WC, Samuel AR.Identification of a fifth neutralizable site on type O foot-and-mouth disease virusfollowing characterization of single and quintuple monoclonal antibody escapemutants.J Gen Virol.1993 Aug; 74 (Pt 8): 1547-53.; Kitson JD, McCahon D, BelshamGJ.Sequence analysis of monoclonal antibody resistant mutants of type O foot andmouth disease virus:evidence for the involvement of the three surface exposedcapsid proteins in four antigenic sites.Virology.1990 Nov; 179 (1): 26-34.], wherein three are arranged in coat protein 1 (Vp1).Experimental results show that, isolated Vp1 albumen has good immunogenicity [Bachrach HL from foot and mouth disease virus, Moore DM, McKercher PD, Polatnick J.Immune andantibody responses to an isolated capsid protein of foot-and-mouth disease virus.JImmunol.1975 Dec; 115 (6): 1636-41.; Kleid DG, Yansura D, Small B, Dowbenko D, MooreDM, Grubman MJ, McKercher PD, Morgan DO, Robertson BH, Bachrach HL.Cloned viralprotein vaccine for foot-and-mouth disease:responses in cattle and swine.Science.1981 Dec 4; 214 (4525): 1125-9.; Strohmaier K, 1982; Rodriguez A, Saiz JC, NovellaIS, Andreu D, Sobrino F.Antigenic specificity of porcine T cell response againstfoot-and-mouth disease virus structural proteins:identification of T helperepitopes in VP1.Virology.1994Nov 15; 205 (1): 24-33.].The neutrality antibody that produces with the proteic peptide section of Vp1 (141-160 and 200-213) immune guinea pig and ox can watch for animals and avoid infecting foot and mouth disease virus [Bittle JL, Houghten RA, Alexander H, Shinnick TM, Sutcliffe JG, Lerner RA, Rowlands DJ, BrownF.Protection against foot-and-mouth disease by immunization with a chemicallysynthesized peptide predicted from the viral nucleotide sequence.Nature.1982 Jul1; 298 (5869): 30-3.; Pfaff E, Mussgay M, Bohm HO, Schulz GE, Schaller H.Antibodiesagainst a preselected peptide recognize and neutralize foot and mouth diseasevirus.EMBO is J.1982; 1 (7): 869-74.; DiMarchi R, Brooke G, Gale C, Cracknell V, DoelT, Mowat N.Protection of cattle against foot-and-mouth disease by a syntheticpeptide.Science.1986 May 2; 232 (4750): 639-41.]." ring " shape structure that VP1 140-160 amino acid constitutes is exposed to virus surface, R-G-D sequence wherein is at the foot and mouth disease virus high conservative, be the key structure of foot and mouth disease virus, may mediate foot and mouth disease virus and enter infected cells [Jackson T, 2002 in conjunction with cell surface receptor; Almeida MR, 1998].Can induce the high-caliber neutralizing antibody of generation according to VP1 ring texture synthetic peptide section.Also there are some researches show, use the Vp1 protein immune animal of separating from foot and mouth disease virus or gene engineering method obtains, can generating unit divide the protection effect.The albumen that Vp1 albumen and some is derived from other microorganisms by genetic engineering means merges and can improve the proteic immunogenicity of Vp1 [Clarke BE, Newton SE, Carroll AR, Francis MJ, Appleyard G, Syred AD, Highfield PE, Rowlands DJ, Brown F.Improved immunogenicityof a peptide epitope after fusion to hepatitis B core protein.Nature.1987 Nov26-Dec 2; 330 (6146): 381-4.; Corchero JL, Villaverde A.Antigenicity of a viralpeptide displayed on beta-galactosidase fusion proteins is influenced by thepresence of the homologous partner protein.FEMS Microbiol Lett.1996 Nov15; 145 (1): 77-82.].

Japanese encephalitis is that the japanese encephalitis virus by Flavivirus causes.Most of people can not fall ill after infecting japanese encephalitis virus.Most to send out patient's clinical symptom lighter, common fever, headache, feels sick, burnout, suffers from abdominal pain or the disturbance of consciousness and mental symptom occur.Severe cases is many to begin with burst high fever, headache, vomiting, and meninges then occurring stimulates phenomenon, and spasm, abnormal behaviour, myotony appear in 3-5 day, consciousness considerable change even stupor, death.

Japanese encephalitis is many countries in the Asia, remain the prevailing disease of serious threat health.Because the enforcement of protective inoculation, the case in Japan, Korea S and Taiwan has reduced much, but many countries that it is contiguous comprise that states such as China's Mainland, Philippines, Indonesia, Malaysia, India, Nepal still have many Japanese encephalitis patients, and idol has the popular of this disease.

Hepatitis B virus is a kind of dna virus.Complete hepatitis B virus particles diameter is 42nm, can be divided into coating and core two portions.Protein on the coating is called hepatitis B surface antigen(HBsAg) (HBsAg), and it is synthetic in liver cell, disengages then in the blood circulation, and itself there is no infectivity.The bifilar DNA of ring-type, archaeal dna polymerase, cAg (HBcAg) and e antigen (HBeAg) are contained in the core, are the main bodys of virus replication, and are infectious.

Acquired immune deficiency syndrome (AIDS) is owing to infected a kind of lethality transmissible disease that causes behind the human immunodeficiency virus (being called for short HIV).HIV mainly destroys the immunity system of human body, and therefore the various pathogenic agent that make body lose protection capability gradually and can not resist the external world very easily infect infectious diseases and the tumour that the general health people is difficult for trouble, finally cause death.China's acquired immune deficiency syndrome (AIDS) epidemic situation was steady ascendant trend in 2000, compared with last one year, and report HIV the infected number increases by 11.2%, and the acquired immune deficiency syndrome (AIDS) case increases by 1.3%.By the end of the year 2000, the accumulation report HIV the infected of 31 provinces, autonomous regions and municipalities in the whole nation (not comprising Taiwan Province, Hong Kong and Macao Special Administrative Region) 22517 examples, wherein acquired immune deficiency syndrome (AIDS) case 880 examples.Report death 496 examples (dead 466 examples of AIDS).Year 2000 report acquired immune deficiency syndrome (AIDS) death 110 examples, dead 17 examples of HIV the infected.

Hiv virus (HIV) is the RNA retrovirus that has coating, belongs to Retroviridae in the classification.HIV is spherical in shape or avette, and diameter 100-130nm is made up of coating and two parts of core.Envelope protein comprises outer membrane glycoprotein (gp120) and transmembrane glycoprotein (gp41).The core is made up of the nucleic acid gene group RNA and the enzyme of nucleocapsid protein, two identical copies.

The present world has developed some and can effectively suppress the medicine of hiv virus, and these medicines can have been alleviated acquired immune deficiency syndrome (AIDS) patient's symptom to a certain extent, prolongs patient's life and improves its quality of life.But these medicines are very expensive, and very big side effect is arranged, and some medicine uses the back that hiv virus has not just been had effect for a long time.At present, our country does not also have the formal entry or produces these medicines.Up to now, also do not develop the thoroughly medicine and the viral vaccine that effectively prevents AIDS of treatment of AIDS in the world.

Papilloma virus belongs to the Papillomavirus of papovaviridae (Papovaviridae), it comprise the papilloma virus of multiple animal and human papillomavirus (Human papillomavirus, HPV).HPV is a kind of little dna virus, and diameter 45～55nm, capsid are the three-dimensional symmetry of icosahedron, contain 72 shell particulates, do not have cyst membrane.The HPV genome is a closed loop distrand DNA, molecular weight 5 * 106 dalton.Can be divided into early stage district (E district), late region (L district) and three zones of non-coding region (NCR) by function.E divides into E1～E7 open reading frame, main coding and virus replication, transcribe, regulation and control and cell transformation proteins associated.L distinguishes L1 and L2, encode respectively main capsid protein and less important capsid protein.NCR is the dna fragmentation of E district and L interval-6.4～1.0bp, can be responsible for the regulation and control of transcribing and duplicating.

Show according to the epidemiology survey data: the infection rate of global papilloma virus is about 9-13%, and promptly annual nearly 600,000,000 3 thousand ten thousand people infect papilloma virus.Papilloma virus and a lot of mucocutaneous disease are closely related.The infection of papilloma virus can cause the verruca plana of skin, phallic pointed condyloma, and the infection of even more serious is papilloma virus and the cancer of cervical cancer, penile cancer and anus are closely related.The U.S. has about 1% the active grownup of sexual life to suffer from pointed condyloma every year, also has at least 15% subclinical infection person in addition.(L Koutsky.Epidemiology of genital human papillomavirus infection.Am JMed，May 5，1997；102(5A)：3-8)。According to The World Health Organization (WHO), annual de novo cervical cancer patient 4.5 ten thousand people in the whole world, its patient of 80% is positioned at developing country, and cervical cancer is women second killer who is only second to mammary cancer.Wherein, the annual new cases 13.5 ten thousand of China account for 1/3rd of the world.Because human papillomavirus (HPV) infects and to increase, the cervical cancer sickness rate is obviously risen and be tending towards rejuvenation in recent years.The patient that cervical cancer is died from (the rich tumour of giving birth to is seeked advice from) whole world every year has 232000 people, wherein 192000 people of developing country

Other studies confirm that, herpes simplex II C-type virus C and human papillomavirus are the important biomolecule factors that causes cervical cancer, is the most common pathogenic agent of genital system infection.Sickness rate by the woman uterus cancer of the simple sore rash of uterine neck II C-type virus C infection is higher than 8 times of healthy womens.Human papillomavirus causes the danger of cervical cancer bigger than herpes simplex II C-type virus C.

The human papillomavirus that identifies at present (HPV) has surpassed 100 types, and different according to each C-type virus C and its pathogenic hazardness are divided into low risk, high-risk-type with HPV.Low risk, mainly cause benign lesions such as pointed condyloma, wherein the infection of HPV 6 types accounts for more than 70%, secondly is HPV11 type (BrownDR.Schroeder JM, Fife KH, etal.Detection of multiplehuman papillomavirus types in condylomata acuminata lesions from otherwise healthy andimmunosuppressed patients.J Clin Microhiol, 1999,37 (10): 3316-3322); High-risk-type, main relevant with the generation of malignant tumours such as cervical cancer, carcinoma vulvae, penile cancer, based on the HPV16 type.(human papillomavirus Progress on Molecular Biology Deng Yan flies in April, 2000 foreign medical science physiology, pathology science and clinical fascicle, the 20th volume, the 2nd phase.)

Take effective vaccine, prevention and treatment parillomarvirus infections are the desirable approach of prevention and treatment cervical cancer and venereal disease complication.Scientist is carrying out unremitting exploration always, attempts to search out a kind of effective vaccine, as dna vaccination, vector-viral vaccine and synthetic peptide vaccine etc.Up to now, do not develop effective papillomavirus vaccine in the world as yet.
