The study compared the cytotoxic effects of various fatty acid derivatives on in vitro breast (MCF7) and prostate (PC3) cell lines. It was found that DHA derivatives, particularly the sn-1,3-diglyceride form known as didocosahexaenoin, were the most effective in terms of cytotoxicity, especially against PC3 prostate carcinoma cells. Didocosahexaenoin exhibited an IC50 of 3.82 ± 0.51 μM on PC3 cells after 96 hours of exposure and demonstrated a 3.26-fold selectivity for cancerous PC3 cells over normal PNT2 prostate cells. The mechanism of action involved the induction of apoptosis through the activation of caspase3/7 and the production of intracellular reactive oxygen species.
