Cynaroside promots macrophage phenotypic transition from pro-inflammatory M1 to anti-inflammatory M2, and mitigates sepsis-associated liver inflammatory damage.
Cynaroside reduces binding of PKM2 to hypoxia-inducible factor-1α (HIF-1α) by abolishing translocation of PKM2 to the nucleus and promoting PKM2 tetramer formation, as well as suppressing phosphorylation of PKM2 at Y105 in vivo and in vitro.
Cynaroside restores pyruvate kinase activity, inhibits glycolysis-related proteins including PFKFB3, HK2 and HIF-1α, and inhibits glycolysisrelated hyperacetylation of HMGB1 in septic liver.
Cynaroside protects H9c2 cells against H2O2-induced apoptosis by decreasing ROS generation and inhibiting caspase activation in both the mitochondrial and death receptor pathways.
Cynaroside maintains mitochondrial function by regulating Bcl-2 protein expression, as well as JNK and P53 expression[2][3].
