TECHNICAL FIELD

The present invention relates to a novel adenine compound which is useful as a prophylactic or therapeutic agent for viral diseases, allergic diseases, etc.

BACKGROUND ART

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.

DISCLOSURE OF INVENTION

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.

BRIEF DESCRIPTION OF FIGURES

FIG. 1 shows anti-HSV activity on a compound of Example 20 against a pathologic modeled-animal infected with HSV-2 in its vagina.

Compound A was spread to a vagina of a female mouse (BALB/c) to which previously Depo-Provera was administered, and on next day, HSV-2 was infected to the vagina. Nine days later, the rate of survival or death of mice was observed and compared.

The compound of the general formula (1) of the present invention or an intermediate thereof which has an acidic functional group such as carboxy group, can be prepared by salt-forming with an optically active amine (an organic amine such as α-phenethylamine, kinin, quinidine, cinchonidine, cinchonine, strychnine, etc.).
The salt formation is carried out at the range from room temperature to the boiling temperature of the solvent. In order to promote the optical purity of the object compound, it is preferable to raise once the temperature to around the boiling point of the solvent. The yield can be raised by cooling the reaction mixture, if necessary, before filtrating a crystallized precipitate. The amount of the optically active acid or amine is preferably about 0.5 to about 2.0 moles per a substrate, more preferably around 1 mole. The precipitate is, if necessary, recrystallized from an inert solvent such as an alcohol-solvent (e.g., methanol, ethanol, 2-propanol, etc.), an ether-solvent (e.g., ethyl ether, etc.), an ester-solvent (e.g., ethyl acetate, etc.), a hydrocarbon-solvent (e.g., toluene, etc.), an aprotic solvent (e.g., acetonitrile, etc.), a mixture thereof to give an optically purified compound. Furthermore, if necessary, an optically resolved salt is treated with an acid or a base by the conventional method to give a free form.
The adenine compound of the present invention, and a tautomer thereof, or a pharmaceutically acceptable salt thereof shows interferon inducting activity, and/or IL-4 and IL-5 production suppressing activity, and therefore, is effective as a prophylactic or therapeutic agent for viral diseases, allergic diseases, or dermatosis. Furthermore, the adenine compound of the present invention, a tautomer thereof, or a pharmaceutically acceptable salt thereof is characterized in, when topically administered, showing an medical effect at the applied lesion, but in systematically showing none of the pharmacological activity because the compound is converted by an enzyme in vivo to other compound (degraded compound) having substantially reduced medical effect and therefore, is useful as a topically administered agent. The medical effect used herein means a pharmacological activity of the compound, such as interferon inducing activity, IL-4 production suppressing activity and/or IL-5 production suppressing activity, etc.
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. The topical administration method is not limited, and the administration is done in case of administration via nasal cavity, alveolus or air way, by aeration or inhalation, in case of administration to skin, by spreading on the skin, and in case of administration to eye, by eye dropping, etc. Preferable administration is done by aeration or inhalation.

Interferon Inducing Activity on Cells of Mouse Spleen (In Vitro)

By using a spleen extracted from a C3H/HeJ mouse (male; 8-10 weeks old), a suspension of spleen cells (2×10⁶cells/ml) was prepared in MEM broth containing 5% FBS. To each well of a 24-well microplate was poured the suspension (0.5 ml). To each well was added 0.5 ml of the test compound (containing 0.2% DMSO) diluted with the same broth, and the microplate was incubated at 37° C. for 24 hours in a 5% CO₂incubator. The culture broth was aseptically filtered by a filter (0.2 micrometer) to give a supernatant. The interferon activity in the supernatant was quantitatively measured by the bioassay method described in J. A. Armstrong, Methods in Enzymology 78, 381˜7. Namely, after mouse fibroblast L929 (1×10⁴cells/50 μl) were cultured in a 96-well culture plate for 24 hours, thereto was added 50 μl of the diluted culture supernatant and the mixture was further cultivated for 24 hours. And then 100 μl of vesicular stomatitis virus were added to each well. Forty four hours after the virus infection, the effect of the cell denaturation was confirmed by the crystal violet stain. The quantitative analysis was carried out by dissolving the pigment in 2% sodium deoxycholate solution and measuring absorbance at 595 nm.

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, 2×10⁴pfu 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.
