Biological Activity

Description (-)-Epicatechin gallate (ECG) is an inhibitor of cyclooxygenase-1 (COX-1) with IC50 of 7.5 μM.
In vitro Treatment of HuH7 cells with (–)-Epigallocatechin gallate (EGCG) causes a time- and dose-dependent decrease in the expression of VEGFR-2 and p-VEGFR-2 proteins. EGCG effectively suppresses the growth of HuH7 human HCC cells both in vitro and in vivo[1]. EGCG potently modulates cardiac excitation contraction coupling by acting on RyR and possibly on L-type Ca2+-channel and NaCa exchanger[2].
In vivo Drinking of EGCG significantly inhibits the growth of HuH7 xenografts in nude mice and this is associated with inhibition of the activation of VEGFR-2 and its related downstream signaling molecules, including ERK and Akt. EGCG drinking also decreases the expression of Bcl-xL protein and VEGF mRNA in the xenografts[1].

Protocol (from reference)

Cell Assay:[1]
  • Cell lines

    HuH7 or Hc cells

  • Concentrations

    0-100 μg/mL

  • Incubation Time

    48 h

  • Method

    Three thousand HuH7 or Hc cells are seeded into 96-well plates. Twenty-four hours later, the cells are treated with the indicated concentrations of EGCG (0–100 μg/mL) for 48 h in DF10 medium, and cell viability is examined. All assays are carried out in triplicate.

Animal Study:[1]
  • Animal Models

    BALB/c nude mice (5 weeks of age)

  • Dosages

    0.01 or 0.1%

  • Administration

    oral administration
