How to use
In Vitro:
KD025 down-regulates the IL-17 and IL-21 secretion in human PBMCs, and leads to down-regulation of STAT3 phosphorylation, IRF4, and RORγt expression in CD4+ T cells. [2] KD025 inhibits the secretion of IL-21, IL-17, and IFNγ along with decreasing phosphorylated STAT3 and reduced protein expression of IRF4 and BCL6 in human peripheral blood mononuclear cells.
In Vivo:
In mice, KD025 (200 mg/kg, p.o.) inhibits ROCK activity in brain and heart, as measured by the degree of MYPT1 phosphorylation. KD025 (200 mg/kg, p.o.) significantly reduces the area of perfusion defect, and reduces tissue loss in the ipsilateral hemisphere. [1] In a collagen-induced arthritis (CIA) mouse model, KD025 (200 mg/kg, i.p.) downregulates the progression of collagen-induced arthritis via targeting of the Th17-mediated pathway. [2] KD025 ()150 mg/kg, i.p. or p.o.) effectively ameliorates cGVHD in a full MHC-mismatch model of multi-organ system cGVHD with bronchiolitis obliterans syndrome and a minor MHC-mismatch model of sclerodermatous GVHD.
