Biological Activity
Methyl alpha-eleostearate (alpha-ESA) is a conjugated polyunsaturated fatty acid commonly found in plant seed oil. This fatty acid accounts for about 60% of the total fatty acid composition of bitter gourd seed oil and about 70% in tung oil. alpha-ESA is metabolized and converted to conjugated linoleic acid (9Z,11E-CLA) in rats. It has shown potential as a tumor growth suppressor. In colon cancer Caco-2 cells, alpha-ESA induced apoptosis through up-regulation of GADD45, p53, and PPARgamma. In DLD-1 cells supplemented with alpha-ESA, apoptosis was induced via lipid peroxidation with an EC50 of 20 uM. It also inhibits DNA polymerases and topoisomerases with IC50s ranging from ~5-20 uM for different isoforms of the enzymes. alpha-ESA methyl ester is a neutral, more lipid soluble form of the free acid.
Safety & Regulatory
For Research Use Only (RUO). Not for therapeutic, diagnostic, or clinical use. Wear appropriate PPE and consult the Safety Data Sheet (SDS) prior to handling.
It is not recommended to store DMSO stock solutions at room temperature. Once the stock solution is prepared, aliquot into single-use volumes and store at −20 °C (or −80 °C for sensitive compounds). Room-temperature storage accelerates chemical degradation and moisture uptake. When ready to use, thaw an aliquot at room temperature, use immediately, and avoid repeated freeze-thaw cycles.
Solubility data for each compound is provided on the TargetMol product page and DataSheet, listed as maximum solubility in DMSO and/or aqueous media (mg/mL and mM). For compounds not yet characterized, prepare a test dissolution at the intended stock concentration and visually confirm clarity before use. When preparing aqueous working solutions, always dilute from a DMSO stock and monitor for precipitation at your final assay concentration.
