产品介绍
Cynaroside (Luteolin 7-glucoside) 是一种具有抗氧化能力的黄酮类化合物。Cynaroside 还是一种流感依赖的RNA 聚合酶抑制剂,IC50为 32 nM。Cynaroside 也是一种应对2O2诱导的细胞凋亡的抑制剂,对氧化应激诱导的心血管疾病具有细胞保护作用。Cynaroside 还具有抗细菌、真菌和抗癌活性,以及抗氧化和抗炎活性。
生物活性

Cynaroside (Luteolin 7-glucoside) is a flavonoid compound that exhibits anti-oxidative capabilities. Cynaroside is also a potent influenza RNA-dependentRNA polymeraseinhibitor with anIC50of 32 nM. Cynaroside also is a promising inhibitor for H2O2-inducedapoptosis, has cytoprotection against oxidative stress-induced cardiovascular diseases. Cynaroside also has antibacterial, antifungal and anticancer activities, antioxidant and anti-inflammatory activities[1][3][4][5].

IC50& Target

IC50:32 nM (RNA polymerase inhibitor)[2]

体外研究
(In Vitro)

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].
