Definitions
- the present invention relates to a novel adenine compound useful as a therapeutic agent for a viral disease or an allergic disease, or a prophylactic agent.
- Interferon is an endogenous protein that plays an important role in the mammalian immune system, and plays an important role in the non-specific defense mechanism as well as in the biological non-specific defense mechanism.
- interferon is used in clinical practice as a therapeutic agent for viral diseases such as hepatitis B and C.
- Low molecular weight organic compounds (interferon inducers) that induce the biosynthesis of interferin are being developed as next-generation interferon agents, and imidazoquinoline derivatives (see European Patent Application Publication No. 145340).

- imidazoquinoline derivative imiquimod is an external antiviral agent for genital warts. Used in clinical practice.
- T cells that play a central role in the immune response in vivo are Thl cells.
- Th2 cells are classified into two types.In the body of patients with allergic diseases, excessive secretion of cytokines such as interleukin-4 (IL-4) and interleukin-5 (IL-5) secreted by Th2 cells Thus, compounds that suppress the immune response of Th2 cells can be expected to be therapeutic agents for allergic diseases.
- cytokines such as interleukin-4 (IL-4) and interleukin-5 (IL-5) secreted by Th2 cells
- the above imidazoquinoline derivatives and adenine derivatives are known to exhibit interleukin-inducing activity and interleukin_4 (IL-4) and interleukin-5 (IL-5) production inhibitory activity, In fact, it is known to be effective in allergic diseases in animal models.
- the problem to be solved by the present invention is to provide a drug for local administration characterized by suppressing a systemic side reaction based on the interferon-inducing activity. That is, when administered topically, a novel adenine compound characterized by being rapidly metabolized and converted into a low-active substance, and systemic pharmacological activity containing the same as an active ingredient were reduced.
- Another object of the present invention is to provide a drug for local administration which is used for treatment or prevention of a viral disease, cancer or allergic disease.
- the present inventors have found that, when used externally as a liniment, a spray, or the like, which is useful for diseases such as asthma, allergic drugs exhibiting excellent effects at the local administration and exhibiting no systemic side reactions.
- the adenine compound of the present invention showed a medicinal effect on a disease model animal by topical administration, and was administered by force.
