产品描述 | Micheliolide(MCL) is a sesquiterpene lactone which inhibits various inflammatory response. |
体外活性 | Treatment of BV2 cells with Micheliolide(MCL) significantly repressed LPS-stimulated nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) expression, as well as tumor necrosis factor-alpha (TNF-α), interleukin-6 (IL-6) and nitric oxide (NO) induction.?MCL also attenuated mRNA levels of multiple pro-inflammatory cytokines and mediators such as iNOS, COX-2, TNF-α, IL-6 and IL-1β.?Mechanistic studies revealed that MCL suppressed LPS-stimulated the activation of IκBα/NF-κB pathway and Akt pathway.?Moreover, MCL inhibited LPS-induced the activition of c-Jun N-terminal kinase (JNK), p38 MAPK kinase, and extracellular signal-regulated kinases 1/2 (ERK1/2).?Meanwhile, MCL markedly promoted antioxidant protein heme oxygenase-1 (HO-1) expression by enhancing NF-E2-related factor 2 (Nrf2) activity.?Together, ?MCL may serve as a neuroprotective agent in neuroinflammation-related neurodegenerative disorders. |
细胞实验 | BV2 cells were pretreated with the indicated concentrations of Micheliolide?1 h prior to stimulation with LPS (1 μg/ml) for 6 h and total RNA was extracted using RaPure Total?RNA Kit.Reverse transcription was performed using RevertAid First Strand cDNA Synthesis Kit.?Real-time PCR analysis was performed using SYBR Select Master Mix ?in conjunction with an ABI Prism 7500 Sequence Detection System with the expression of β-actin as the internal control.?The data were analyzed using the ΔΔCT method.?The primers for iNOS, COX-2, TNF-α, IL-1β, IL-6 and β-actin were described as below. |

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。
