COX-1:3.2 μM (IC50)

In Vitro (-)-Epicatechin exhibits >95% inhibitory activity at 70 μg/mL against cyclooxygenase-1 (COX-1) with an IC50 of 3.2 μM[1]. (-)-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 Hodgkin's 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[2].
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[3].
Animal Admin Mice[3] 1-year-old, male C57BL/6N mice (n=25) are randomized into four groups. Mice in the (-)-Epicatechin groups 3 and 4 are given 1.0 mg/kg twice a day (morning and evening) for 15 consecutive days, whereas animals in the control groups 1 and 2 receive the vehicle (water). Both (-)-Epicatechin and vehicle are administered via oral gavage[3].
