α-Eleostearic acid  (Synonyms: cis-Eleostearic acid)

α-Eleostearic acid (cis-Eleostearic acid), a conjugated linolenic acid, is an apoptosis inducer. α-Eleostearic acid is also a ferroptosis inducer. α-Eleostearic acid exhibits antioxidant and antitumor activity^[1][2][3].

α-Eleostearic acid (0-40 μM; 24 h) inhibits the growth of some cancer and fibroblast cell lines, including those of HL60 leukemia and HT29 colon carcinoma^[1].
α-Eleostearic acid (20 μM; 6 h) induced cellular and nuclear fragmentation, and nucleosomal DNA fragmentation typical of apoptosis in HL60 leukemia cells^[1].
α-Eleostearic acid (0.01-100 μM; 72 h) triggers death of MDA-MB-231 cells and this death was suppressed by Fer-1, Deferoxamine, and vitamin E^[3].

α-Eleostearic acid (0.5% of total lipid given; p.o.) inhibits Sodium Arsenite-induced oxidative stress, including reversal of antioxidant enzyme activity and reduction of lipid peroxidation levels^[2].
Oral administration of tung oil, naturally rich inα-Eleostearic acid, to mice limits tumor growth and metastasis in an aggressive TNBC orthotopic xenograft model^[3].
