Product-Name:(-)-Epicatechin gallate

(-)-Epicatechin gallate is a flavan-3-ol, a type of flavonoid, present in green tea.
IC50 value:
in vitro: epicatechin gallate, a constituent of an extract of tea leaves (green tea) markedly lowered the minimum inhibitory concentration (MIC) of oxacillin and other beta-lactams, but not of other antibacterial agents tested, in strains of methicillin-resistant Staphylococcus aureus [1]. Epicatechin, as well as many other flavonoids, has been found to act as a non-selective antagonist of the opioid receptors, albeit with somewhat low affinity [2].
