体外研究(In Vitro)

(-)-Epicatechin exhibits >95% inhibitory activity at 70 μg/mL against cyclooxygenase-1 (COX-1) with an IC50 of 3.2 μM. (-)-Epicatechin inhibits the IL-1β-induced expression of iNOS by blocking the nuclear localization of the p65 subunit of NF-κB. In RINm5F cells, (-)-Epicatechin is shown to block the inhibition of insulin release after addition of IL-1β. Additionally, (-)-Epicatechin is shown to inhibit the proliferation of Hodgkins lymphoma cells and Jurkat T cells, which is attributed to the ability of (-)-Epicatechin to inhibit the binding of NF-κB to DNA in these cells. In human colorectal cancer HCT-116 cells, combining 20?μM Panaxadiol with 150, 200, or 250?μM (-)-Epicatechin results in growth inhibition of 51%, 97%, and 95%, respectively. The combination also increases the apoptosis level by 11.9%, 16.6%, and 25.8%, as examined by annexin V/PI staining.

体内研究(In Vivo)

Animals receive 1 mg/kg of (-)-Epicatechin or water (vehicle) via oral gavage (twice daily). Exercise groups undergo 15 days of treadmill exercise. Significant increases in treadmill performance (~50%) and enhanced in situ muscle fatigue resistance (~30%) are observed with (-)-Epicatechin.Medlife has not independently confirmed the accuracy of these methods. They are for reference only.

产品使用指南

Data Sheet

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。
