Phytochemical Name : Eleostearic acid (alpha-ESA)

Properties Information
PhytoCAT-ID PhytoCAT-1170
Phytochemical name or plant extracts Eleostearic acid (alpha-ESA)
PMID 19789297
Literature evidence We found that alpha-ESA inhibited proliferation of both MDA-wt and MDA-ERalpha7 cells, whereas conjugated linoleic acid had comparatively weak antiproliferative activity at 20 to 80 micromol/L concentrations.
IUPAC name octadeca-9,11,13-trienoic acid

Plant parts Seeds
Other cancers Breast cancer
Target gene or protein HER2/HER3, PTEN
Gene or Protein evidence Western blot analysis revealed that α-ESA treatment not only reduced HER2/HER3 protein expression, but also increased the level of phosphorylated phosphatase and tensin homolog protein (PTEN), which led to decreased levels of phosphorylated
Target pathways Akt/GSK-3β survival pathway , Akt/BAD/Bcl-2 apoptotic pathway
IC50 NA
Potency Alpha-ESA can block breast cancer cell proliferation and induce apoptosis through a mechanism that may be oxidation dependent.
Cell line/ mice model MDA-MB-231, SKBR-3, T47D
Additional information  Therefore, α-ESA may be considered a beneficial dietary factor for the prevention and treatment of invasive breast cancer in cells overexpressing HER2.
