Biological Activity:
Chrysophanic acid (Chrysophanol) is a EGFR/mTOR pathway inhibitor. Chrysophanic acid (Chrysophanol) is a natural anthraquinone, has anticancer activity in EGFR-overexpressing SNU-C5 human colon cancer cells. Chrysophanic acid (Chrysophanol) preferentially blocked proliferation in SNU-C5 cells but not in other cell lines (HT7, HT29, KM12C, SW480, HCT116 and SNU-C4) with low levels of EGFR expression. Chrysophanic acid (Chrysophanol) treatment in SNU-C5 cells inhibited EGF-induced phosphorylation of EGFR and suppressed activation of downstream signaling molecules, such as AKT, extracellular signal-regulated kinase (ERK) and the mammalian target of rapamycin (mTOR)/ribosomal protein S6 kinase (p70S6K). Chrysophanic acid (80 and 120 µM) significantly blocked cell proliferation when combined with the mTOR inhibitor, rapamycin. [1]References on Chrysophanic acid (Chrysophanol)[1] Phytother.
