Corosolic acid (Colosolic acid) isolated from the fruit of Cratoegus pinnatifida var. psilosa, was reported to have anticancer activity. Corosolic acid induces cancer cell apoptosis[1][2][3].

In Vitro

Corosolic acid shows cytotoxicity for Hep G2, A549, SNU-C4, HeLa, K-562 cells, with ED50s of 0.4-5.0 μg/mL[1].
Corosolic acid (0-50 μg/mL) inhibits PKC activity in a dose-dependent way[1].
Corosolic acid (0-50 μM, 6-24 h) induces apoptosis and increases cells in the sub-G1 population in CT-26 cells[3].
Corosolic acid (20 μM, 0-24 h) inhibits HER2/HER3 heterodimerization and phosphorylation of HER2 and HER3 in HCT116 and SW480 cells[5].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Apoptosis Analysis[3]

Cell Line: CT-26 cells
Concentration: 25 µM
Incubation Time: 12 and 24 h
Result: Increased cleaved caspase-3 level.
Increased cells in the sub-G1 population.
Increased fluorescin-dUTP labeling DNA strand breaks.

Western Blot Analysis[5]

Cell Line: HCT116 and SW480 cells
Concentration: 20 μM
Incubation Time: 0-24 h
Result: Decreased the formation of NRG1-induced HER2/HER3 heterodimer.
Inhibited the PI3K/Akt/PDE3B but not the ERK1/2 signaling pathway.
In Vivo

Corosolic acid (5, 25 mg/kg/day, peritumor injection, 12 days) inhibits tumor growth and shows anti-angiogenic effect in CT-26 allograft colon carcinoma mice model[3].
Corosolic acid (10 and 20 mg/kg, i.p., every 2 days) inhibits tumor growth in a murine PC-3 xenograft model by activating ER stress[4].
Corosolic acid (10 mg/kg/d, supplemented in diet, 8 weeks) inhibits adipose tissue inflammation, and improves insulin resistance via AMPK activation in high-fat fed mice[6].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model: CT-26 allograft colon carcinoma mice model[3]
Dosage: 5, 25 mg/kg/day
Administration: Peritumor injection, 12 days
Result: Reduced the tumor weight to 76.2% and 53.8% of the control group.
Reduced blood and lymphatic vessel densities.
Animal Model: high-fat fed mice[6]
Dosage: 10 mg/kg/day
Administration: Supplemented in diet, 8 weeks
Result: Inhibited hyperlipidemia, Improved insulin sensitivity and glucose intolerance.
Inhibited inflammation in adipose tissues.
Inhibited macrophage infiltrations into adipose tissue.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
