1 It was observed that there was a positive correlation (r = 0.760) between the sensitivity of the human placental COMT to heat inactivation and its sensitivity to inhibition by (-)-epigallocatechin-3-gallate (a well known tea polyphenol with COMT-inhibiting activity) but an inverse correlation (r = 0.544) between heat inactivation and inhibition by quercetin (another dietary COMT inhibitor).
