9Z,11E,13E-Octadecatrienoic Acid (α-ESA) is a conjugated polyunsaturated fatty acid found in plant seed oil. This fatty acid makes up about 60% of the total fatty acid composition of bitter gourd seed oil and about 70% in tung oil. In rats, 9Z,11E,13E-Octadecatrienoic was metabolized and converted to conjugated linoleic acid (9Z,11E-CLA). It has shown potential as a tumor suppressor. In Caco-2 colon cancer cells, alpha-ESA triggered apoptosis through up-regulation of GADD45, p53, and PPARγ. In DLD-1 cells supplemented with 9Z,11E,13E-Octadecatrienoic, apoptosis was triggered via lipid peroxidation. It also inhibits DNA polymerases and topoisomerases with IC50s ranging from ~5-20 µM for different isoforms of the enzymes.
