Not Intended for Therapeutic Use. For research use only.
Chrysophanic acid (Chrysophanol) is a a natural anthraquinone, has anticancer activity in EGFR-overexpressing SNU-C5 human colon cancer cells. Chrysophanic acid 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 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. These findings offer the first evidence of anticancer activity for chrysophanic acid via EGFR/mTOR mediated signaling transduction pathway.

1.Simultaneous quantification of chrysophanol and physcion in rat plasma by ultra fast liquid chromatography-tandem mass spectrometry and application of the technique to comparative pharmacokinetic studies of Radix et Rhei Rhizoma extract alone and Dahuang Fuzi Decoction.
Liu X1, Li H2, Wu L3, Xing J4, Poh Y5, Cai H3, Cai BC6. J Chromatogr B Analyt Technol Biomed Life Sci. 2015 Feb 1;980:88-93. doi: 10.1016/j.jchromb.2014.11.025. Epub 2014 Dec 24.
Most herbal medicines are prescribed in combination based on the theory of TCM to obtain synergistic effects or diminish the possible adverse reactions. Compatibility refers to the combination of two or more herbs based on the clinical settings and the properties of herbs. Chrysophanol and physcion are the main effective compounds in Radix et Rhizoma Rhei and Dahuang Fuzi Decoction which is the combination of Radix et Rhizoma Rhei, Radix Aconiti Lateralis Praeparata and Radix et Rhizoma Asari. However, chrysophanol and physcion are difficult to detect in vivo because of their low concentration and interference from endogenous compounds. The aim of this study is to develop a rapid, specific and sensitive ultra high performance liquid chromatography-triple quadrupole tandem mass method to simultaneously quantify chrysophanol and physcion in rat plasma, in order to better understand the pharmacokinetics and compatibility mechanism of Dahuang Fuzi Decoction for the first time.
2.[Total quantity statistical moment analysis on pharmacokinetics of rhein and chrysophanol after oral administration of Quyu Qingre granules in normal and acute blood stasis rabbits].
Yan YL, Dai XY. Zhongguo Zhong Yao Za Zhi. 2014 Feb;39(3):520-5.
This study aim to reveal the total pharmacokinetics of rhein and chrysophanol after oral administration of Quyu Qingre granules (QUQRG) in normal and acute blood stasis rabbits, to identify the pharmacokinetics differences between two groups of rabbits and to evaluate the applicability of the total statistical moment analysis. Based on the concentrations of rhein and chrysophanol in plasma determined by an established HPLC method, and the calculation of main total pharmacokinetic parameters, this study found that total pharmacokinetic parameters VRT, value of blood stasis group is lager than that of normal group and the difference is significant Compared with normal group, total pharmacokinetic parameters AUC,, MRT,, t1/2t, and Vt value of blood stasis group is lager, while the k, and CL, value is smaller. The findings indicated that the absorbed and released time of rhein and chrysophanol was accelerated and the total absorptive amount of these two compounds was increased in rabbits with acute blood stasis, compared with the normal rabbits.

4.[Effects of chrysophanol on expression of SREBPs and lipid metabolism in Huh-7 cells].
Li JM, Ding LL, Song BL, Yang L, Wang ZT. Yao Xue Xue Bao. 2015 Feb;50(2):174-9.
Rhubarb is a traditional Chinese medicines which possess laxative, lipid-lowering, and weight-loss activities, but the active compounds of lipid-lowering and underlying molecular mechanisms are not yet clear. This study aims to explore the effects of chrysophanol on the mRNA expressions of sterol regulatory element-binding proteins (SREBPs) and lipid metabolism in human liver carcinoma Huh-7 cells, which is one of the active compounds obtained from Rhubarb. A reporter gene assay was used to test the transcription of SREBP. The intracellular triglyceride and total cholesterol contents were measured by using commercially available test kits. The SREBPs target genes expressions were measured by Quantitative Real-Time PCR. Cell viability was evaluated by Cell Counting Kit-8. As the results shown, chrysophanol (40 μmol · L(-1), 16 h) could notably inhibited human SRE promoter activity in a dose-dependent manner and decrease intracellular cholesterol and triglyceride levels.
