Janus kinase (JAK) is a family of intracellular, nonreceptor tyrosine kinases that transduce cytokine-mediated signals via the JAK-STAT pathway. They were initially named "just another kinase" 1 and 2 (since they were just two of many discoveries in a PCR-based screen of kinases), but were ultimately published as "Janus kinase". The name is taken from the two-faced Roman god of beginnings, endings and duality, Janus, because the JAKs possess two near-identical phosphate-transferring domains. One domain exhibits the kinase activity, while the other negatively regulates the kinase activity of the first.
The invention provides a baricitinib polymorph A. The baricitinib polymorph A is characterized in that diffraction peaks are arranged on an XRPD (X RayPowderDiffraction) map when values of 2 theta are equal to 12.46, 13.921, 14.94, 15.359, 16.26, 16.639, 17.36, 19.08, 20.321, 21.961, 22.381, 24.118, 25.42, 27.441, 28.381, 29.321, 29.799, 32.675, 33.14, 33.563, 33.923 and 41.6, wherein an error range of the values of the 2 theta is + / - 0.2. The baricitinib polymorph A provided by the invention has good high-temperature stability, good high-humidity stability and good illumination stability, can be applied to medicine for treating or preventing diseases related to JAK (Janus Kinase) and has better biological availability; meanwhile, provided qualitative and quantitative information has important significance in further studying the therapeutic effect of such solidmedicine.
