Zedoarondiol has anti-inflammatory activity, inhibits iNOS, COX-2, and pro-inflammatory cytokine expressions by suppressing the phosphorylations of IKK and MAPKs, and by subsequently inactivating the NF-kappaB pathway.

体外活性 | In this study, we investigated the anti-inflammatory effects of Zedoarondiol, a sesquiterpene lactone isolated from the rhizoma of Curcuma heyneana, in lipopolysaccharide (LPS)-stimulated macrophage cells. Zedoarondiol dose-dependently inhibited LPS-stimulated nitric oxide (NO), prostaglandin E(2) (PGE(2)), tumor necrosis factor-alpha (TNF-alpha), interleukin-6 (IL-6), and interleukin-1beta (IL-1beta) productions in RAW 264.7 macrophage and in mouse peritoneal macrophage cells. Consistent with these findings, in RAW 264.7 cells, Zedoarondiol suppressed the LPS-stimulated protein levels of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) and the mRNA expressions of iNOS, COX-2, TNF-alpha, IL-6, and IL-1beta in a concentration-dependent manner. Moreover, molecular data revealed that Zedoarondiol inhibited LPS-stimulated DNA binding activity and the transcription activity of nuclear factor-kappa B (NF-kappaB), and this effect was accompanied by decreases in the degradation and phosphorylation of inhibitory kappaB (IkappaB)-alpha, and in the subsequent blocking of NF-kappaB translocations to the nucleus. Furthermore, Zedoarondiol attenuated the phosphorylations of IkappaB kinase (IKK), extracellular signal-regulated kinase (ERK), p38 mitogen-activated protein kinase (p38), and c-Jun N-terminal kinase (JNK) in LPS-stimulated RAW 264.7 cells. |

对于不同动物的给药剂量换算,您也可以参考 更多...
请在以下方框中输入您的动物实验信息后点击计算,可以得到母液配置方法和体内配方的制备方法: 比如您的给药剂量是10 mg/kg,每只动物体重20 g,给药体积100 μL,一共给药动物10 只,您使用的配方为5% DMSO+30% PEG300+5% Tween 80+60% ddH2O。那么您的工作液浓度为2 mg/mL。
母液配置方法:2 mg 药物溶于 50 μL DMSO (母液浓度为 40 mg/mL), 如您需要配置的浓度超过该产品的溶解度,请先与我们联系。
体内配方的制备方法:取 50 μL DMSO 主液,加入 300 μL PEG300, 混匀澄清,再加 50 μL Tween 80,混匀澄清,再加 600 μL ddH2O, 混匀澄清。
