This invention discloses a compound with a pyrrolopyridine structure, its preparation method, and its pharmaceutical uses. This invention provides a novel compound with a pyrrolopyridine structure and a method for synthesizing this series of compounds. Activity studies show that the compound with the pyrrolopyridine structure possesses excellent JAK
protein kinase inhibitory activity. Those skilled in the art know that JAK
protein kinase plays an important role in the occurrence and development of various diseases, such as various immune diseases,
myeloproliferative disorders, and
central nervous system inflammatory diseases; inhibiting JAK can treat or alleviate these diseases. Therefore, the compound with the pyrrolopyridine structure provided by this invention has the potential for development into a JAK inhibitor
drug and for treating or alleviating diseases by inhibiting JAK.
