摘要:
The present invention provides a compound having excellent JAK3 inhibitory activity and being useful as an active ingredient of an agent for treating and/or preventing various immune diseases including autoimmune diseases, inflammatory diseases, and allergic diseases. As a result of investigations with respect to novel condensed heterocyclic derivatives, the inventors have verified that a condensed pyridine compound has excellent JAK3 inhibitory activity, thereby completing the present invention. More specifically, it has been verified that since the compound according to the present invention has inhibitory activity against JAK3, the compound is useful as an active ingredient of an agent for treating or preventing diseases caused by undesirable cytokine signal transduction (e.g., rejection during live organ/tissue transplantation, autoimmune diseases, asthma, atopic dermatitis, rheumatism, psoriasis and atherosclerotic disease), or diseases caused by abnormal cytokine signal transduction (e.g., cancer and leukemia).
摘要:
[Problem] On the basis of a cathepsin S inhibitory effect, an excellent agent for treating or preventing autoimmune disease, allergic disease, graft rejection of an organ, bone marrow or tissue, systemic lupus erythematosus, or the like is provided. [Means for Solution] It was found that a nitrogen-containing bicyclic heterocyclic compound has the excellent cathepsin S inhibitory effect, thereby completing the invention. The compound of the present invention has the cathepsin S inhibitory effect, and can be used as an agent for preventing and/or treating autoimmune disease, allergic disease, graft rejection of an organ, bone marrow or tissue, systemic lupus erythematosus, or the like.
摘要:
[Problem] The present invention provides a condensed pyrrolopyridine derivative which is useful as an active ingredient for a pharmaceutical composition, in particular, a pharmaceutical composition for preventing or treating diseases caused by undesirable cytokine signal transduction or diseases caused by abnormal cytokine signal transduction. [Means for Solution] The present inventors have extensively studied a compound having a JAK inhibitory action, and as a result, they have found that a condensed pyrrolopyridine derivative which is the compound of the present invention has an excellent JAK inhibitory action, and is therefore useful as an agent for preventing or treating diseases caused by undesirable cytokine signal transduction or diseases caused by abnormal cytokine signal transduction, thereby completing the present invention.
摘要:
The present invention provides a compound of formula (I) having an excellent JAK3 inhibition activity and being useful as an active ingredient of an agent for treating and/or preventing various immune diseases including autoimmune diseases inflammatory diseases, and allergic diseases. The compound according to the present invention has an inhibition activity against JAK3 and is thus useful as an active ingredient of an agent for treating or preventing diseases caused by undesirable cytokine signal transmission (e.g., rejection during organ/tissue transplantation, autoimmune diseases, multiple sclerosis, rheumatoid arthritis, psoriasis, asthma, atopic dermatitis, Alzheimer's disease, and atherosclerotic disease), or diseases caused by abnormal cytokine signal transmission (e.g., cancer and leukemia).
