| Hazard Information | Back Directory | [Uses]
Kurarinone is an orally active flavonoid isolated from matrine that inhibits the pathogenesis of experimental autoimmune encephalomyelitis by inhibiting cell differentiation of Th1 and Th17. Kurarinone has antitumor and anti-inflammatory activity[1][2][3]. | [Definition]
ChEBI: (2S)-(-)-kurarinone is a trihydroxyflavanone that is (2S)-flavanone substituted by hydroxy groups at positions 7, 2' and 4', a lavandulyl group at position 8 and a methoxy group at position 5. Isolated from the roots of Sophora flavescens, it exhibits cytotoxicity against human myeloid leukemia HL-60 cells. It has a role as a metabolite and an antineoplastic agent. It is a trihydroxyflavanone, a monomethoxyflavanone and a member of 4'-hydroxyflavanones. It is functionally related to a (2S)-flavanone. | [Biological Activity]
Kurarinone, a flavonoid isolated from Sophora flavescens, inhibits the pathogenesis of experimental autoimmune encephalomyelitis by inhibiting the differentiation of Th1 and Th17 cells. | [Physiological effects]
Kurarinon has an anti-endothelial cell proliferative activity, and it has a significant inhibitory effect on endothelial cell proliferation with a median inhibitory concentration (IC50) of 12ug/ml. | [in vivo]
Kurarinone (100 mg/kg，口服，第 21-42 天) 在胶原诱导关节炎 (CIA) 小鼠模型中具有治疗作用[3]。
? Kurarinone (100 mg/kg，p.o.，from day 21-42) has a therapeutic effect in a mouse model of collagen-induced arthritis (CIA)[3].
| Animal Model: | CIA Mouse Model[3] | | Dosage: | 100 mg/kg | | Administration: | p.o. | | Result: | Reduced the levels of proinflammatory cytokines, TNF-α, IL-6, IFN-γ, and IL-17A.
Reduced STAT1 and STAT3 phosphorylation and the proportions of Th1 and Th17 cells in lymph nodes.
