Baricitinib 巴瑞克替尼; LY3009104; INCB028050

Baricitinib是一种选择性JAK1和JAK2抑制剂，无细胞试验中IC50分别为5.9 nM和5.7 nM，比作用于JAK3和Tyk2选择性高70和10倍左右，对c-Met和Chk2没有抑制作用。Baricitinib被发现可以减少或干扰病毒进入目标细胞，并用于COVID-19的治疗研究中。Phase 3

CAS No.	1187594-09-7
生物活性	Baricitinib (LY3009104; INCB028050) is a selective and orally bioavailable JAK1 and JAK2 inhibitor with IC50s of 5.9 nM and 5.7 nM, respectively.
分子式	C16H17N7O2S
分子量	371.42
储存条件	Powder -20℃ 3 years
溶解性数据	DMSO : 25 mg/mL (67.31 mM; Need ultrasonic and warming)
体内研究	Baricitinib (INCB028050) treatment, compares with vehicle, inhibits the increase in hind paw volumes during the 2 wk of treatment by 50% at a dose of 1 mg/kg and >95% at doses of 3 or 10 mg/kg. Because baseline paw volume measurements are taken on treatment day 0-in animals with significant signs of disease-it is possible to have >100% inhibition in animals showing marked improvement in swelling. Baricitinib (0.7 mg/day) treated mice exhibits substantially reduced inflammation as assessed by H&E staining, reduced CD8 infiltration, and reduced MHC class I and class II expression when compared with vehicle-control treated mice. CD8NKG2D cells, critical effectors of disease in murine and human alopecia areata (AA), are greatly diminished in Baricitinib treated mice compare with vehicle control treated mice.
体外研究	In cell-based assays, Baricitinib (INCB028050) 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.
