1,4-Dicaffeoylquinic Acid

1,4-Dicaffeoylquinic acid is a polyphenol that has been found in C. coronarium and has diverse biological activities. It scavenges DPPH (Cay-14805) radicals and inhibits xanthine oxidase (XO, IC50 = 7.36 µM). 1,4-Dicaffeoylquinic acid (25 µM) decreases protein levels of tyrosinase and microphthalmia-associated transcription factor (MITF) in B16/F1 murine melanocytes, inhibits melanogenesis in the same cells, and decreases tyrosinase activity in B16/F1 cell lysates. It increases biliary flow in rats in a dose-dependent manner.Formal Name: (1alpha,3R,4alpha,5R)-rel-1,4-bis[[3-(3,4-dihydroxyphenyl)-1-oxo-2-propen-1-yl]oxy]-3,5-dihydroxy-cyclohexanecarboxylic acid.
