• the present application belongs to the field of medicinal chemistry, and relates to the therapeutic use of a pyrrolopyrimidine compound and its solid pharmaceutical composition.
• Januskinase is a type of non-receptor tyrosine kinase (PTK) that exists in cells and transmits cytokine stimulation signals through the JAK-STAT pathway.
• the JAK-STAT pathway transmits chemical signals from outside the cell through the cell membrane to the gene promoter located on the DNA in the nucleus, which ultimately affects the changes in DNA transcription and activity levels in the cell.
• the JAK-STAT pathway consists of three main parts: 1) receptors; 2) bifacial kinase (JAK) and 3) signal transduction and transcriptional activation protein (STAT).
• the receptor can be activated by interferon, interleukin, growth factor, or other chemical messengers, and the activation leads to JAK autophosphorylation; then the STAT protein binds to the phosphorylated receptor, so that the STAT is phosphorylated by JAK; then the STAT protein is phosphorylated Separated from the receptor, dimerized and translocated into the nucleus to bind to specific DNA sites and change transcription (Scott, MJ, CJ Godshall et al. (2002). "Jaks, STATs, Cytokines, and Sepsis" Clin Diagn Lab Immunol 9(6): 1153-9).
