Description

PYRIMIDONES AS ANTIVIRAL AGENTS

The present invention relates to vinylpyrimidine-2-one derivatives, the use of the vinylpyrimidine-2-one derivatives as pharmaceutically active agents, especially for the prophylaxis and/or treatment of infectious diseases including opportunistic infections, cell proliferation disorders, cardiovascular disorders, immunological diseases, inflammatory diseases, neuroimmunological diseases, autoimmune diseases, as well as compositions containing at least one vinylpyrimidine-2-one derivative and/or pharmaceutically acceptable salt thereof, and methods for preventing and/or treating such diseases. Furthermore, a process for preparing said vinylpyrimidine-2-one derivatives is disclosed using the corresponding diketones as starting materials.

Background of the invention

Human Cytomegalovirus (HCMV) is a highly specific β-herpesvirus. Primary infection of healthy children and adults is usually asymptomatic, with a minority of cases developing a mononucleose-like syndrome. In contrast, congenital infection (U.S. 0.2%-2.2% per live birth; approx. 40,000 per year) leads to several neurological defects in 10-15% of infected neonates. Immunocompromised patients represent another host group facing serious disease complications caused by HCMV infection or reactivation of a persistent infection. Up to 40% of the AIDS patients, for example, develop retinitis, pneumonitis, gastroenteritis or disseminated HCMV disease. In addition, allograft recipients (20,000 allograft transplantations per year in the U.S.) are often infected (or superinfected) by virus from the transplanted organ.

Clinical symptoms in the posttransplant period include prolonged fever, leukopenia, thrombocytopenia, atypical lymphocytosis, elevated hepatic transaminases and decreased graft survival. In bone marrow transplantations, HCMV infection is associated with high mortality rates (80-90% for untreated HCMV pneumonia). Current approaches to develop therapeutics against Cytomegalovirus (CMV) have focused on antiviral agents per se; for example viral polymerase inhibitors. In fact, high mortality rates have been dramatically reduced by new antiviral agents. Current CMV therapeutics possess severe drawbacks, however. For example, Fomivirsen (Vitravene, formerly ISIS 2922) is typically administered by injection directly into the eye every 2 or 4 weeks. Ganciclovir is available for intravenous (Cytovene) or oral administration, and as an implant in the case of retinitis; unfortunately, toxic complications including leukopenia and thrombocytopenia frequently develop. Foscarnet (Foscavir; phosphonoformic acid), another antiviral agent, exhibits considerable renal toxicities and is only available in intravenous form (which is also true for Cidofovir (Vistide), another CMV therapeutic). In addition, CMV replication resumes soon after Ganciclovir and Foscarnet treatment is halted. Finally, Ganciclovir- and Foscarnet-resistant strains of CMV are emerging.

Although treatment of HCMV-induced disease has been improved with these inhibitors of the viral polymerase and preemptive or early antiviral therapy in transplant patients, there is a need in the art for a new class of HCMV therapeutics with better oral bioavailability and reduced toxic effects. This is especially true in the treatment of retinitis in AIDS patients, where CMV infection must be controlled for long periods of time.

Recent research has revealed how cells communicate with each other to coordinate the growth and maintenance of the multitude of tissues within the human body. A key element of this communication network is the transmission of a signal from the exterior of a cell to its nucleus, which results in the activation or suppression of specific genes. This process is called signal transduction.

An integral part of signal transduction is the interaction of cytokines, their receptors, and intracellular signal transduction molecules. Cytokines serve as messengers that bind to receptors on the surface of a target cell. As a result of the binding, the receptors activate a cascade of downstream signaling molecules, thereby transmitting the message from the exterior of the cell to its nucleus. Signal transduction to the nucleus modulates specific gene expression (i.e., transcription and translation), which results in either the upregulation or downregulation of specific proteins that carry out a particular biological function.

Viral infection disrupts normal signal transduction, which leads to cellular malfunctioning resulting in a disease state. Specifically, interference of HCMV with relevant human primary cells is necessary for the virus to create an environment that allows it to grow and replicate, and in turn cause disease in the infected individual. Current research efforts have failed to elucidate all the specific intracellular signal pathways affected by HCMV infection, however. Discovery of the signal transduction pathways and specific intracellular signal transduction molecules affected by CMV infection would represent a tremendous advance in the understanding of the induction and progression of CMV infection processes and provide new avenues for the development of a novel class of effective therapeutics for the treatment of CMV.

It is object of the present invention to provide compounds which can be used as pharmaceutically active agents, especially for prophylaxis and/or treatment of infectious diseases, cell proliferation disorders, cardiovascular disorders, immunological diseases, inflammatory diseases, neuroimmunological diseases, autoimmune diseases, and pharmaceutical compositions comprising said compounds and/or pharmaceutically acceptable salts thereof as pharmaceutically active ingredients.

This step is described for example by S. Dilli and K. Robarts, Australian Journal of Chemistry 1978, 31 , 1833-7; Ka et al., European Journal of Medicinal Chemistry 1995, 30, 423-7; H. G. Bonacorso et al., Journal of Fluorine Chemistry 1999, 99, 177-82; K. Mitsuhashi et al. , Heterocycles 1994, 37, 1141 -1146.

These pyrimidones of formula (II) or formula (Ma) can be separated by chromatography, for example by column chromarography on silica gel [A. Katoh et al., Chem. Pharm. Bull. 1994, 42(7), 1514-1517; C. Kashima, A. Katoh, J. Heterocyclic Chem. 1980, 17, 913-915].

Other aspects of the present invention relate to vinylpyrimidine-2-one derivatives of the general formula (I) or vinylpyrimidine-2-one derivatives of the general formula (la) as new pharmaceutically active agents, especially for the preparation of a pharmaceutical composition for the treatment of diseases which are cured or relieved by the inhibition of kinases and/or phosphatases. The compounds of the general formula (I) or compounds of the general formula (la) were surprisingly identified as potent inhibitors for human and viral kinases, especially of herpesviral kinases such as UL97.

Thus, a method is disclosed herein for preventing and/or treating diseases which are cured or relieved by the inhibition of kinases and/or phosphatases in a mammal, including a human, which method comprises administering to the mammal an amount of at least one compound of general formula (I) or compounds of the general formula (la) and/or pharmaceutically acceptable salts thereof, effective to prevent and/or treat said diseases which are cured or relieved by the inhibition of kinases and/or phosphatases. A preferred embodiment of said method involves the herpesviral kinase UL97 as a target for preventing and/or treating herpesviral infections and diseases.

Another method is directed to the prophylaxis and/or treatment of infectious diseases, including opportunistic infections in a mammal, including a human. Said method comprises administering to the mammal an amount of at least one compound of the general formula (I) and/or at least one compound of the general formula (la) and/or pharmaceutically acceptable salts thereof, effective to prevent and/or treat said infectious disease and/or opportunistic infection.

This relationship between a herpesviral kinase such as UL97 and the effective treatment of heφesviral infections led to the conclusion that the signal transduction mediated by a herpesviral kinase such as UL97 is essential for virus replication. Inhibition of said kinase, therefore, may decrease or inhibit the replication of herpes viruses. Surprisingly, it was found that the vinylpyrimidine-2-one derivatives of the general formula (I) or vinylpyrimidine-2-one derivatives of the general formula (la) act as potent inhibitors of a herpesviral kinase such as UL97 and the effect of decreasing up to preventing virus replication was observed. Thus, a method for preventing and/or treating herpesviral infections and/or associated diseases in a mammal, including a human, is disclosed herein. Said method comprises the administration of a pharmaceutically effective amount of at least one compound of general formula (I) and/or at least one compound of the general formula (la) to said mammal, wherein said compound inhibits at least partially the activity of the herpesviral kinase UL97.

It can be stated that the vinylpyrimidine-2-one derivatives of the general formula (I) or vinylpyrimidine-2-one derivatives of the general formula (la) can be used for prophylaxis and/or treatment of infectious diseases, including opportunistic infections, especially of herpes and diseases caused by herpes viruses.

Herpesviruses may be selected from the group comprising α-herpesviruses (Simplexvirus, Varicellavirus), β-herpesviruses (Cytomegalovirus also known as human herpesvirus 5, Muromegalovirus, Roseolovirus), or γ-herpesviruses

(Lymphocryptovirus, Rhadinovirus). Examples for α-herpesviruses are Herpes simplex virus type 1 (human herpesvirus 1 ), Herpes simplex virus type 2 (human herpesvirus 2), Varicella Zoster virus (human herpesvirus 3). Examples for γ- herpesviruses are Epstein-Barr virus (human herpesvirus 4) or human herpesvirus type 8 (HHV8). More preferably, the herpesvirus is Herpes simplex virus type 1 , or Varicella Zoster virus, or Epstein-Barr virus (EBV), or human cytomegalovirus

(HCMV), or human herpesvirus 6, or human herpesvirus 7, or human herpesvirus type 8 (HHV8). Most preferably, the herpesvirus represents the α-herpesviruses Herpes simplex virus type 1 , or Varicella Zoster virus, or the γ-herpesviruses

Epstein-Barr virus, or Human Herpes virus type 8.

The herpesvirus family comprises the human herpesviruses 1 to 8 and different herpes viruses for various animal species as shown below in Table 1 : Table 1 : Members of the herpesvirus family

Preferably, the herpes virus is selected from the group comprising herpes simplex viruses, varicello viruses, cytomegalo viruses, muromegalo viruses, roseolo viruses, lymphocrypto viruses, and rhadino viruses. In the following some important members of the herpes virus family are described.

Herpes simplex virus type 1 (HSV-1) Herpes simplex virus is a highly adapted human pathogen with an extremely rapid lytic replication cycle, and yet with the ability to invade sensory neurons where highly restricted gene expression occurs with the absence of cytopathology.

Such latent infections are subject to reactivation whereby infectious virus can be recovered in peripheral tissue enervated by the latently infected neurons following a specific physiological stress. A major factor in these "switches" from lytic to latent infection and back involves the interaction between viral promoters, the viral genome, and cellular transcriptional machinery. Herpes simplex virus types 1 and 2 are generally associated with mucocutaneous facial infection (herpes labialis), genital infection (herpes genitalis), ophthalmic infection (herpes keratitis) and neonatal infection. The lesions are generally self-healing, but the infection remains, with the virus establishing latent infection in the neurons. In immunocompromised hosts, recurrence of HSV-1 may cause progressive fulminant lesions that are refractory to current antiviral therapy. Neonatal infection is usually systematically spread and may lead to encephalitis. Current antiviral therapy like Acyclovir does not eliminate viral infection. New therapies are needed to either eliminate latent virus or to suppress lesion development over the long term.

Epstein-Barr virus (EBV)

Epstein-Barr virus, frequently referred to as EBV, is a member of the herpesvirus family and one of the most common human viruses. The virus occurs worldwide, and most people become infected with EBV sometime during their lives. In the United States, as many as 95% of adults between 35 and 40 years of age have been infected. Infants become susceptible to EBV as soon as maternal antibody protection (present at birth) disappears. In the United States and in other developed countries, many persons are not infected with EBV in their childhood years. When infection with EBV occurs during adolescence or young adulthood, it causes infectious mononucleosis 35% to 50% of the time.

Symptoms of infectious mononucleosis are fever, sore throat, and swollen lymph glands. Sometimes, a swollen spleen or liver involvement may develop. Heart problems or involvement of the central nervous system occurs only rarely, and infectious mononucleosis is almost never fatal. There are no known associations between active EBV infection and problems during pregnancy, such as miscarriages or birth defects. Although the symptoms of infectious mononucleosis usually resolve in 1 or 2 months, EBV remains dormant or latent in a few cells in the throat and blood for the rest of the person's life. Periodically, the virus can reactivate and is commonly found in the saliva of infected persons. This reactivation usually occurs without symptoms of illness.

EBV also establishes a lifelong dormant infection in some cells of the body's immune system. A late event in a very few carriers of this virus is the emergence of Burkitt's lymphoma and nasopharyngeal carcinoma, two rare cancers that are not normally found in the United States. EBV appears to play an important role in these malignancies, but is probably not the sole cause of disease. No antiviral drugs or vaccines for EBV except Ganciclovir are available.

Human herpesvirus 8 (HHV8), or Kaposi's sarcoma-associated herpesvirus (KSHV)

KSHV is a virus belonging to the family of herpesviruses. KSHV was discovered in 1994. The virus has two names that are commonly used: KSHV which is its descriptive name and HHV8 which is its formal name. Both names are essentially interchangeable. KSHV causes a blood vessel cancer called Kaposi's sarcoma (KS), a lymphoma (a cancer of the lymphocyte) called body cavity-based lymphoma and some forms of severe lymph node enlargement, called Castleman's disease. The rates of KSHV infection in the general population of Mediterranean countries (Italy, Greece, Israel, Saudi Arabia) are higher than in North America and Northern Europe. Adult populations in some portions of Africa have very infection rates (>50%). This virus can be transmitted through sexual contact. KSHV is also probably transmitted to some extent through nonsexual routes, perhaps from oral contact (kissing). Once exposed to KSHV, infection is probably life-long and the immune system of healthy adults keeps the virus in check at extremely low levels. The real problem with KSHV occurs when an infected person becomes immunosuppressed. This occurs among transplant patients and patients receiving chemotherapy. There is good evidence that if someone is infected with KSHV and becomes immunosuppressed, then their chances of developing clinically detectable disease due to KSHV is higher than for other common viral infections. Infection with KSHV is diagnosed by a blood test. It now seems likely that early in the AIDS epidemic there were actually two simultaneous virus epidemics: the well-recognized epidemic of HIV and a second 'silent' epidemic of KSHV. Only those persons who became immunosuppressed by HIV developed KS. KSHV is probably less transmissible than HIV, certainly this is true from blood products and sharing needles, and so only the fraction of persons developing AIDS were infected with KSHV and developed KS. KSHV- related disease can also occur in persons without obvious immunodeficiency, but this is rare and primarily occurs among elderly men. There has been a major epidemic of KS in some parts of Africa, especially Eastern and Southern Africa, concurrent with the African HIV pandemic. KS is now the most common tumor reported in several African cancer registries. While most African KS patients are also HIV infected, these areas also have the world's highest rates of this disease for non HIV-infected persons. There is no vaccine for KSHV. Existing therapy is Ganciclovir.

Varicella-zoster virus (VZV)

Chicken pox is an infection that is caused by the Varicella-zoster virus (VZV). VZV spreads in nasal discharge and in fluid from inside the chicken pox blisters. Chicken pox is very contagious, and 90% of people who are not immune will catch it when they are exposed. Epidemics are most common in the late winter and early spring, and children between ages 5 and 9 account for half of all cases.

Normally, chicken pox is a mild illness, but it can cause serious complications, including pneumonia, encephalitis, and serious bacterial infections of chicken pox blisters. After causing an attack of chicken pox, VZV remains in the body. It lies dormant in nerve cells and may be reactivated later in life to cause shingles. Children (and others) who develop varicella and have weakened immune systems may be treated with Acyclovir.

Having identified the herpesviral kinase UL97 as potent target for prophylaxis and/or treatment of herpesviral infections and/or diseases associated with herpesviral infections a method for the identification of potent inhibitior for UL97 has been designed. Said method comprises contacting a test compound with the herpesviral kinase UL97 and detecting a change in activity of said cellular kinase. Potent inhibitors such as the vinylpyrimidin-2-one derivatives of the general formula (I) will markedly diminish the activity of the herpesviral kinase UL97.

The compounds of formula (I) or of formula (la) can also be used in the form of a precursor (prodrug) or a suitably modified form, that releases the active compound in vivo. Such precursors can be obtained for example by masking the free acid group with an ester group, which is then in turn transformed into the free acid group in vivo [F. W. Sum et. al. Bioorg. & Med. Chem. Lett. 9 (1999), 1921-1926; Ada Rephaeli et. al. Drug Development Research 50 (2000) 379-391 ; H. Ishikawa, Current Med. Chem. 6 (1999), 575-597].

The compounds of the general formula (I) or compounds of the general formula (la) can also be administered in form of their pharmaceutically active salts optionally using substantially nontoxic pharmaceutically acceptable carriers, excipients or diluents. The medications of the present invention are prepared in a conventional solid or liquid carrier or diluents and a conventional pharmaceutically- made adjuvant at suitable dosage level in a known way.

For preparing suppositories, a low melting wax such as a mixture of fatty acid glycerides such as cocoa butter is first melted, and the active ingredient is dispersed homogeneously therein by stirring or similar mixing. The molten homogeneous mixture is then poured into convenient sized molds, allowed to cool and thereby solidifies.

Also included are solid form preparations which are intended to be converted, shortly before use, to liquid form preparations for either oral or parenteral administration. Such liquid forms include solutions, suspensions and emulsions.

The inventive vinylpyrimidine-2-one compounds of the present invention may also be deliverable transdermally. The transdermal compositions may take the form of creams, lotions, aerosols and/or emulsions and can be included in a transdermal patch of the matrix or reservoir type as are conventional in the art for this purpose.

The term capsule refers to a special container or enclosure made of methyl cellulose, polyvinyl alcohols, or denatured gelatins or starch for holding or containing compositions comprising the active ingredients. Hard shell capsules are typically made of blends of relatively high gel strength bone and pork skin gelatins. The capsule itself may contain small amounts of dyes, opaquing agents, plasticizers and preservatives.

Tablet means compressed or molded solid dosage form containing the active ingredients with suitable diluents. The tablet can be prepared by compression of mixtures or granulations obtained by wet granulation, dry granulation or by compaction well known to a person skilled in the art.

Oral gels refers to the active ingredients dispersed or solubilized in a hydrophilic semi-solid matrix.

Powders for constitution refer to powder blends containing the active ingredients and suitable diluents which can be suspended in water or juices. Suitable diluents are substances that usually make up the major portion of the composition or dosage form.

Materials and methods

UL97 Kinase-Assay on Immobilon Plate The effect of the vinylpyrimidine-2-one derivatives were tested on the activity of the viral kinase UL-97. This kinase is derived from human cytomegalovirus (HCMV) (Marschall, M., Stein-Gerlach, M., Freitag, M., Kupfer, R., van den Bogaard, M. & Stamminger, T.; Inhibitors of human cytomegalovirus replication drastically reduce the activity of the viral protein kinase pUL97. J. Gen. Virol. 2001 , 82, 1439-1450.). The UL-97 gene was cloned into a baculovirus vector in order to produce GST (glutathione S-transferase) fusion protein. Insect cells (Sf9) were infected and GST-UL-97 purified via glutathione affinity columns according to standard procedures.

UL-97 Kinase Reaction

The UL-97 kinase reaction was performed as described (Marschall et al., 2001 , 1439-1450). Briefly, 10 μl Assay buffer (3 μM ATP, 60μg/ml myelin basic protein (MBP) as substrate), 1 ,0 μCi α-[³³P]ATP and 10 μl Basic buffer (20mM Tris-HCl 7.5, 500μM MnCI₂, 1 mM DTT (dithiothreitol)) were given to the test tube before adding various concentrations of the vinylpyrimidine-2-one derivatives. The reaction was started by adding 0.2 μl UL97 kinase, purified from infected Sf9- insect cells as described above. The total volume was adjusted with Basic buffer to a final volume of 30 μl. The reaction mix was incubated for 1 hr at 30°C. For negative control, 10 μl 0.1 M EDTA (ethylene diamine tetraacetate) was added to the reaction mix before addition of UL-97 protein kinase. The reaction was stopped by addition of 10 μl 0.1 M EDTA.

Measuring Incorporation of Radioactivity

The Immobilon plate (Millipore) was rinsed with 50μl methanol/well. Following addition of 100 μl 0.1 M EDTA, 20 μl of each kinase reaction mix was added to one well of the Immobilon plate. Each well was washed 4x with 250 μl 0.75% phosphoric acid and 1x with 50 μl methanol. After addition of 50 μl scintillation cocktail (Roth, Germany) per well incorporation of radioactivity was measured using a Betareader (Wallac) and enzymatic activity calculated.

ii) Compounds belonging to the class of vinylpyrimidine-2-one derivatives have been identified as potent inhibitors of HCMV replication in vitro with IC50 values as low as 3 μM and thus are as good as the gold standard ganciclovir (IC50 3-4 μM). Furthermore, compounds of the class of vinylpyrimidine-2-ones block pUL97 kinase activity at sub - and low micromolar concentrations. Their IC50 values for blocking the kinases p38, EGF-Reα, JNK, Abl, PKC, Akt, Ins.-Rec, c-kit, Lck, MAPK, c-met, p70S6, PDGF-Rec. and src. are far higher than 10 μM.
