No. 10/528,343 filed Mar. 18, 2005, which is the national stage of International Application PCT/JP2008/012320, filed Sep. 26, 2003, which claims priority under 35 USC §119(a)-(d) of Japanese Application No. 2002-283428, filed Sep. 27, 2002 and of Japanese Application No. 2002-301213, filed Oct. 16, 2002.
The present invention relates to a novel adenine compound which is useful as a prophylactic or therapeutic agent for viral diseases, allergic diseases, etc.
Interferon is an endogenous protein which plays an important role in mammalian immune system, takes a part of nonspecific defensive mechanism in vivo and greatly participates also to specific defensive mechanism in vivo. In fact, interferon has been used in the clinical field as a therapeutic agent for viral diseases, such as hepatitis B and C, etc. Low molecular weight organic compounds which induce biosynthesis of said interferon (interferon inducers) have been developed as an interferon preparation in next generation. Imidazoquinoline derivatives (see European Patent Publication A 145340), adenine derivatives (see WO 98/01448 and WO 99/28321), etc. are illustrated. For example, Imiquimod, an imidazoline derivative is used in the clinical field as an external antiviral agent for genital verruca.
By the way, T cells which play the key role of the immunological response in vivo are classified into two kinds, Th1 cells and Th2 cells. In the body of patients suffering from allergic disease, cytokines such as interleukin 4 (IL-4), interleukin 5 (IL-5), etc. are excessively secreted from TH2 cells and therefore, it is expected that the compound which suppresses immune response of Th2 cells becomes a therapeutic agent for allergic diseases.
It is known that the above imidazoquinoline derivatives and adenine derivatives have not only the interferon inducing activity, but also have the activity suppressing the production of interleukin 4 (IL-4) and interleukin 5 (IL-5). In fact it is known that these derivatives are effective for allergic diseases on animal model.
However, there is anxiety for systemic adverse-effects due to the interferon inducing activity such as fever, interferon-like diseases when these derivatives are administered as an antiallergic agent.
The problem to be solved by the present invention is to provide a topically administrable medicament which is characterized in suppressing the systemic adverse effect caused by interferon inducing activity.
That is, the present invention provides a novel adenine compound which is characterized in being quickly metabolized to change a less active compound when it is topically administered, and a topically administrable medicament containing this compound as an active ingredient, which is used as the therapy for viral diseases, cancer or allergic diseases, whose systemic pharmacological activity is lessened.
The present inventors have been extensively studied in order to obtain a therapeutic and prophylactic agent for immune deficiency such as allergic diseases which shows excellent effect in the applied area and does not show the systemic adverse effect, when it is externally used in the form of liniments or aerosols useful for diseases such as asthma, etc. and as a result have found that the adenine compounds of the present invention show surprisingly excellent effect on pathologically modeled animals and is characterized in being quickly metabolized in the applied area or the body to change into a less active compound. Namely, the compounds of the present invention are reduced in the systemically pharmacological activity and are useful as a therapeutic or prophylactic agent for viral diseases, cancer, allergic diseases, etc. The present invention was completed based on the above findings.

The medical effect of the degraded compound is preferably 10 times, more preferably 100 times, further more preferably 1000 times reduced comparing with that of the parent compound.
Said pharmacological activities can be evaluated by the conventional measuring method known in the art, preferably by the measuring method in vitro. For example, there are illustrated methods described in Method in ENZYMOLOGY (Academic press), etc. or the method by using the commercialized ELISA Kit (e.g., AN′ ALYSA (Immunoassay System), etc.), or the method described in Example of the present specification, etc.
For example, by measuring interferon inducing activity with bioassay using cells of mouse spleen, the amount of each interferon induction (IU)/ml at the same concentration of the parent compound (the compound of the present invention) and the degraded compound can be compared. In addition, each concentration showing the definite amount of interferon production can be compared with the parent compound and its degraded compound, too.
As a pharmacological activity, the activity in vivo caused by interferon inducing activity, etc. is illustrated. Said activity in vivo includes immune activating activity, influenza-like symptom, etc. The immune activating activity includes the induction of cytotoxic activity such as NK cells, etc. The influenza-like symptom includes fever, etc. The fever means the rise of the body temperature of a mammalian, for example, in case of human, the fever means that the body temperature rises more than normal temperature.

Example 125 Metabolic Stability on River S9 of Rat
The reaction on river S9 of a rat was carried out on a 96-well plate by using a robot for screening by Tecan Company. S9 solution was prepared by adding to 10 ml of liver S9 of a rat, 20 ml of 250 mM Kpi (pH 7.4) and 20 ml of deionized water. Cofactor solution was prepared by dissolving NADPH (220 mg) in deionized water (40.5 ml) to give finally a 6 mM solution. IS (Internal Standard) solution was prepared by adding 300 μL of IS solution (1 mM DMSO solution) to 30 ml of acetonitrile solution (100 times dilution). The test compound (1 μM DMSO solution) was dissolved in an incubator at 37° C., 35 μL of it was poured into each well of a 96-well plate (24 samples/plate and then, plates (a sample plate, a 96 well-plate for dilution, deep well plates for reaction and recovering, a plate for extraction of the solid phase) and the test samples (S9 solution, Cofactor solution, IS (Internal Standard) solution, Stop solution, acetonitrile for elution) were set to the specified position in the booth of the robot. The reaction started (the concentration of the test compound was 1 μM) and the mixture was incubated at 37° C. under stirring. The solid phase was extracted and at the same time the internal standard for analysis was added. To the recovered sample (200 μL/well) was added 50 μL of acetonitrile per each well and to 2 plates of FALCON Deep well were poured 100 μL of the solution per well. By subjecting to the LC/MS analysis, the chromatogram of the test sample and the internal standard were described and the peak area was calculated. And then, the stability (residual rate after reaction) was calculated by the internal standard method. The result was shown in Table 4.

Example 127 Anti HSV Activity of Antedrug for Herpes Virus (HSV) Infected Vagina of Modeled Rat
On the back of a BALB/c female mouse (6 weeks old: Nippon SLC) 3 mg of Depo-Provera/mouse (Registered Trade Mark) was dermally administered and the mice were fed for 6 days. By doing this the sexual cycle was tuned and the sensitivity between mice to herpes virus was balanced. The slime of mouse vagina was removed by a cotton swab for baby, and the ointment (20 mg) containing 0.5% of compound of Example 20 or the ointment (10 mg) containing 5% of compound of Example 20 was spread to the vagina(corresponding 0.1 mg and 0.5 mg per mouse of the compound of Example). As a control, the placebo ointment not containing the compound was spread as well. As the ointment, the base consisting of 80% Vaseline and 20% liquid paraffin were used. On the next day, the slime of mouse vagina was removed by a cotton swab for baby and then, 2×104 pfu type 2 herpes virus (HSV-2)(10 μl/mouse) was administered to the vagina by pipette. After infection the death or survival of the mice was observed.
The survived rate of mice 9 days later after virus-infection was shown in FIG. 1. The groups spread by the ointments containing 0.5% and 5% of the compound of Example 20, respectively showed clearly higher survived rate comparing with a control group, and the dosage dependency was observed. Furthermore, though the survived rate of the control group was 0%, in the group of 5% ointment its survived rate was 100% and the latter showed clearly anti-viral effect.
