Description
Technical field
The present invention relates to a kind of polymorphic of the cyclopropanecarbonyl amine derivative as JAK inhibitor, in particular it relates to one
Plant cyclopropanecarbonyl amine derivative C crystal form and preparation method thereof.
Background technology
JAK is Janus kinases (Janus Kinase), is a kind of non-receptor type tyrosine protein kinase, is also that a class is non-
The EGFR-TK of transmembrane.Because JAK can phosphorylation cytokine receptor combined with it, and can phosphorylation it is many
The individual signaling molecule containing specific SH2 domains.JAK protein families include 4 members altogether：JAK1, JAK2, JAK3 and TYK2,
They have 7 JAK homeodomains (JAK homology domain, JH) in structure, wherein JH1 domains be kinases area,
JH2 domains are that "false" kinases area, JH6 and JH7 are receptorbinding regions.
TYK2 is the potential target spot of Immunoinflammatory Disorders, rejects research confirmation (Levy by people's science of heredity and mouse
D. with Loomis C., 1655-1658 pages of New England Journal of Medicine 357 (2007)).
JAK1 is the novel targets in Immunoinflammatory Disorders field.By JAK1 and other JAK heterodimericization, with the transducer cell factor
The pro-inflammatory signals conduction of driving.Therefore, it is contemplated that suppression JAK1 and/or other JAK is for a series of inflammatory conditions with other by JAK
The disease of the signal transduction driving of mediation has treatment benefit.
Cyclopropanecarbonyl amine derivative, chemical name N- [5- [4- [(1,1- dioxo -4- thio-morpholinyls) methyl] phenyl]
[1,2,4] triazol [1,5-A] pyridine -2- bases] cyclopropane carboxamide, as shown in formula (I),
