Outline of Final Research Achievements

The aim of the present study was to elucidate the mechanism of synergistic enhancement of vasorelaxation by food compounds. It was demonstrated that vasorelaxation of anti-atherosclerotic di-peptide, Trp-His, was synergistically enhanced by the epigallocatechingallate through their enhancement of NO production signals. The present study also showed that the synergistic vasorelaxation by Trp-His/EGCg was attenuated by a pro-inflammatory cytokine TNF-α treatment, and the attenuated vasorelaxation was restored by a widely present natural phenolic acid, ferulic acid.
