[PROBLEMS] To provide a compound having an excellent JAK3-inhibiting activity and useful as an active ingredient for a therapeutic or prophylactic agent for various immune diseases including autoimmune diseases, inflammatory diseases and allergic diseases. [MEANS FOR SOLVING PROBLEMS] A study is made on a novel condensed heterocyclic derivative, and it is confirmed that the condensed pyridine compound of the invention has an excellent JAK3-inhibiting activity. It is confirmed that the compound is useful as an active ingredient for a therapeutic or prophylactic agent for a disease induced by undesirable cytokine signaling such as rejection upon living donor transplantation, an autoimmune disease, asthma, atopic dermatitis, rheumatism, psoriasis and atherosclerosis or a disease induced by abnormal cytokine signaling such as cancer and leukemia because of its inhibitory activity on JAK3.

L'objet de l'invention est un composé présentant une excellente activité d'inhibition de JAK3 et utile en tant que principe actif pour un agent thérapeutique ou prophylactique pour diverses maladies immunitaires y compris des maladies auto-immunes, des maladies inflammatoires et des maladies allergiques. Une étude est réalisée sur un nouveau dérivé hétérocyclique condensé, et il est confirmé que le composé de pyridine condensée de l'invention possède une excellente activité d'inhibition de JAK3. Il est confirmé que le composé est utile en tant que principe actif pour un agent thérapeutique ou prophylactique pour une maladie induite par une signalisation indésirable de cytokines telle que le rejet après transplantation de donneur vivant, une maladie auto-immune, l'asthme, la dermite atopique, les rhumatismes, le psoriasis et l'athérosclérose ou une maladie induite par une signalisation anormale de cytokines telle qu'un cancer et une leucémie grâce à son activité inhibitrice sur JAK3.
