体外研究(In Vitro) |
(-)-Epigallocatechin (EGC) is a potent inhibitor of amyloidogenic cystatin I66Q amyloid fibril formation 体外研究. Computational analysis suggests that (-)-Epigallocatechin prevents amyloidogenic cystatin fibril formation by stabilizing the molecule in its native-like state as opposed to redirecting aggregation to disordered, amorphous aggregates [1]. Combined curcumin and EGCG treatment reduced the cancer stem-like Cluster of differentiation 44 (CD44)-positive cell population. Western blot and immunoprecipitation analyses revealed that curcumin and (-)-Epigallocatechin (EGC) specifically inhibited STAT3 phosphorylation and STAT3-NFkB interaction was retained [2]. (-)-Epigallocatechin (EGC) exhibits a MIC and MBC of 5 μg/mL and 20 μg/mL respectively and effectively eradicated E. faecalis biofilms. (-)-Epigallocatechin induces the formation of hydroxyl radicals in E. faecalis. The addition of DIP protected E. faecalis against EGCG-mediated antibacterial effects. At sub-MIC, (-)-Epigallocatechin induces significant down-regulation of E. faecalis virulence genes [3]. Medlife has not independently confirmed the accuracy of these methods. They are for reference only. |

1:一般建议:溶解度为Medlife测试数据,可能与文献描述存在差异。这是由于生产工艺和批次不同产生的正常现象。为了使其更好的溶解,请用37℃加热试管并在超声波水浴中震动片刻。不同批次产品溶解度各有差异,仅做参考,具体以实验方案为准。
2:储存条件:粉末-20°C一般情况可以保存3年,溶于溶剂-80°C一般情况可以保存1年。不同产品及不同批次产品可能存在差异,请细致阅读产品信息,并辅助参考相关文献描述。
