1,4-Dicaffeoylquinic acid (1,4-DCQA) 是一种来自苍耳子 的苯丙素，可抑制 LPS 刺激的 TNF-α 产生。
1,4-Dicaffeoylquinic acid is a polyphenol that has been found in C. coronarium and has diverse biological activities.1,2,3,4 It scavenges DPPH radicals and inhibits xanthine oxidase (XO; IC50 = 7.36 ?M).1,2 1,4-Dicaffeoylquinic acid (25 ?M) 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.3 It increases biliary flow in rats in a dose-dependent manner.4
