(Abstract) gamma-Linolenic acid (GLA) is reported to show tumor-selective cytotoxicity through unidentified mechanisms. Here, to assess the involvement of oxidized metabolites of GLA, we synthesized several deuterated GLAs and evaluated their metabolism and cytotoxicity towards normal human fibroblast WI-38 cells and VA-13 tumor cells generated from WI-38 by transformation with SV40 virus. Deuteration of GLA suppressed both metabolism and cytotoxicity towards WI-38 cells and increased the selectivity for VA-13 cells. Fully deuterated GLA was visualized by Raman imaging, which indicated that GLA is accumulated in intracellular lipid droplets of VA-13 cells. Our results suggest the tumor-selective cytotoxicity is due to GLA itself, not its oxidized metabolites.(MeSH Terms)
