| 体外研究 | Astragalin suppressed cellular induction of Toll-like receptor 4 (TLR4) and ROS production enhanced by LPS. H2O2-upregulated phosphorylation of JNK and p38 MAPK was dampened by adding astragalin to epithelial cells, while this compound enhanced epithelial activation of Akt and ERK. H2O2 and LPS promoted epithelial apoptosis, which was blunted by astragalin [1]. Astragalin suppressed the expression of TNF α, IL- 6, and nitric oxide in a dose-dependent manner in mMECs [2]. Astragalin attenuated the infiltration of inflammatory cells, the activity of MPO and the expression of TNF-α, IL-6 and IL-1β in a dose-dependent manner. Additionally, Astragalin efficiently blunt decreased nuclear factor-kappaB (NF-κB) activation by inhibiting the degradation and phosphorylation of IκBα and the nuclear translocation of p65 [3]. Astragalin significantly reduced LPS-induced expression of iNOS, COX-2 and cytokines/chemokines, and production of NO in J774A.1 mouse macrophages. [4]. | ||||
| 体内研究 | Mice were injected intraperitoneally (i.p.) with lipopolysaccharide (LPS) (dose range: 5-40 mg/kg). pretreatment with astragalin can improve survival during lethal endotoxemia and attenuate inflammatory responses in a murine model of lipopolysaccharide-induced acute lung injury [4] | ||||
