MedKoo Cat#: 600131 | Name: Epicatechin
Featured

Description:

WARNING: This product is for research use only, not for human or veterinary use.

Epicatechin is a flavanol found in food sources such as tea, apples, berries and cocoa. Epicatechin has been reported to possess an immense antioxidant effect which contributes to its therapeutic effect against a handful of ailments. The consumption of epicatechin has been shown to reduce blood glucose levels in diabetic patients, while its anticancer effect was attributed to its antioxidant properties, antiangiogenic and direct cytotoxicity to cancer cells. Epicatechin lowers blood pressure and the associated end-organ damage.

Biological target:
(-)-Epicatechin inhibits cyclooxygenase-1 (COX-1) with an IC50 of 3.2 μM.
In vitro activity:
ROS, LDH, MDA, and SOD assays were performed in our study to evaluate the antioxidant activity of ECG. OGD/R induced an ROS level about 2.5-fold to control (normal), whereas ECG downregulated ROS significantly compared with the OGD/R group (P < 0.01) (Figure 2(a)). OGD/R induced oxidative stress, and the LDH level was used to assess cell death. ECG treatment significantly inhibited LDH leakage induced by OGD (P < 0.01) (Figure 2(b)). As shown in Figure 2(c), OGD/R upregulated intracellular MDA levels compared with control which was significantly decreased by ECG treatment (Figure 2(c)). As MDA was considered an indicator of lipid peroxidation, ECG may show inhibition of lipid peroxidation in HBMVECs that underwent OGD/R. In the OGD/R group, the SOD activities were significantly decreased compared with the control group (Figure 2(d)). ECG treatment significantly increased SOD activity (P < 0.01).

In vivo activity:
The acetic acid-induced writhing and hot plate models in mice were utilized to determine the analgesic effect of epicatechin gallate (ECG) isolated from Bauhinia hookeri. The anti-inflammatory activity of ECG was determined using carrageenan-induced paw edema model. The pro-inflammatory mediators (PGE2 , TNF-α, IL-1β, and IL-6) were estimated in the plasma of different treatment groups. ECG was tested at doses of 100, 200, and 400 mg/kg p.o. and diclofenac sodium was used as a standard drug (100 mg/kg) in all experiments. ECG significantly (p < .001) suppressed the writhing response in mice. The inhibition percentages were 32, 52, and 62%, at the tested doses of ECG, respectively as compared to the positive control group receiving acetic acid only. Furthermore, ECG significantly (p < .001) increased the reaction time in hot plate model. The maximum analgesic effect was evident after 120 min. ECG demonstrated a significant anti-inflammatory activity as evidenced by the inhibition of carrageenan-induced paw edema (46, 50, and 58%, at the tested doses, respectively). This effect was persistent all over the experimental period. ECG produced a significant (p < .001) reduction in plasma PGE2 (by 27, 38, and 50%), TNF-α (15, 33, and 41%), IL-1β (17, 25, and 33%), and IL-6 (22, 32, and 43%), at the tested doses, respectively. This study supports the use of ECG as both analgesic and anti-inflammatory agent. Reference: Drug Dev Res. 2018 Jun;79(4):157-164. https://doi.org/10.1002/ddr.21430
