体外活性 | This study was undertaken to isolate active secondary metabolites from immunostimulatory Alcaligenes faecalis FY-3 and evaluate their activities using grass carp Ctenopharyngodon idella kidney (CIK) cells. METHODS AND RESULTS:By applying chromatography techniques and successive recrystallization, three purified metabolites were obtained and identified by spectral data (mass spectrometry and nuclear magnetic resonance) as: (1) phenylacetic acid, (2) p-hydroxyphenylacetylamide and (3) Cyclo(Gly-L-Pro). CIK cells were stimulated by different concentrations (1, 10 and 100 μg/ml) of the isolated compounds, and expression of MyD88, IL-1β, TNF-α, type I-IFN and IL-8 genes at different time points (2, 8 and 24 h) post-stimulation was quantified by real-time PCR. The known immunostimulatory agent lipopolysaccharide (LPS) was used as a positive control. To analyse whether these compounds are toxic to the cells, the methyl tetrazolium assay was employed to measure changes in cell viability. The obtained results revealed that transcribing level of MyD88, an important adaptor molecule in toll-like receptor signalling pathway, was augmented remarkably by all the three isolated compounds and LPS as early as 2-h exposure. These compounds also induced gene expression of cytokines such as IL-1β, TNF-α and type I-IFN. Under the experimental conditions, none of the test compounds is toxic to the CIK cells. CONCLUSIONS:These findings demonstrate that the immunostimulatory properties of the three metabolites [phenylacetic acid, p-hydroxyphenylacetylamide and Cyclo(Gly-L-Pro) ] from A. faecalis FY-3 in CIK cells and highlight the potential of using these metabolites as immunostimulants in fish aquaculture. |

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。
