Baricitinib phosphate salt Chemische Eigenschaften,Einsatz,Produktion Methoden

Verwenden
Baricitinib is a JAK1 and JAK2 inhibitor and have been used as a promising treatment for rheumatoid arthritis.
Biologische Aktivität
direct and indirect inhibition of the jaks has demonstrated rapid and sustained improvement in clinical measures of disease. baricitinib phosphate (incb 028050) is a selective jak1 and jak2 inhibitor.
in vitro
In cell-based assays, Baricitinib phosphate proves to be a potent inhibitor of JAK signaling and function. In PBMCs, Baricitinib inhibits IL-6-stimulated phosphorylation of the canonical substrate STAT3 (pSTAT3) and subsequent production of the chemokine MCP-1 with IC50 values of 44 nM and 40 nM, respectively. In isolated naive T-cells, INCB028050 also inhibits pSTAT3 stimulated by IL-23 (IC50=20 nM). Importantly, this inhibition prevented the production of two pathogenic cytokines (IL-17 and IL-22) produced by Th17 cells-a subtype of helper T cells with demonstrable inflammatory and pathogenic properties-with an IC50 value of 50 nM. In stark contrast, the structurally similar but ineffective JAK1/2 inhibitors INCB027753 and INCB029843 has no significant effect in any of these assays systems when tested at concentrations up to 10 μM.
in vivo
significant efficacy was achieved in the rat adjuvant arthritis model with doses of baricitinib phosphate providing partial and/or periodic inhibition of jak1/jak2 and no inhibition of jak3. baricitinib phosphate was also effective in multiple murine models of arthritis, with no evidence of suppression of humoral immunity or adverse hematologic effects [2].
