Metabolite Identification
Common Name7'-Carboxy-gamma-tocotrienol
Description7'-carboxy-r-tocotrienol is a dehydrogenation carboxylate product of 7'-hydroxy-r-tocotrienol by an unidentified microsomal enzyme(s) probably via an aldehyde intermediate. Gamma-tocotrienol targets cancer cells by inhibiting Id1, a key cancer-promoting protein. Gamma-tocotrienol was shown to trigger cell apoptosis and well as anti-proliferation of cancer cells. This mechanism was also observed in separate prostate cancer and melanoma cell line studies.
