What is KURARINONE?
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.
