β-phenylethyl isothiocyanate (PEITC) is a phytochemical found in cruciferous vegetables with anti-cancer properties in vitro and in vivo. However, its pharmacokinetic profile in cancer survivors were unknown. A pharmacokinetic study was conducted in head and neck cancer survivors to evaluate the absorption and elimination profile of PEITC in the matrix of Nutri-jelly - a novel edible nutritious gel. Twelve head and neck cancer survivors consumed a serving of Nutri-jelly containing 20 mg PEITC. Plasma levels of PEITC at 0, 1, 2, 3, 4, 6, 8, 12 and 24 hours were specifically measured by ammonia derivatization and analyzed by LC-MS/MS. Non-compartmental pharmacokinetic analysis was performed. Pharmacokinetic parameters including Cmax, Tmax, half-life, clearance were analyzed.
This research aims to evaluate the absorption and elimination profile of a bioactive compound PEITC in the matrix of Nutri-jelly - a novel edible nutritious gel. Thus, the investigators conducted a pharmacokinetic study in 12 head and neck cancer survivors. After consumed a serving of Nutri-jelly containing 20 mg PEITC, plasma levels of PEITC at 0, 1, 2, 3, 4, 6, 8, 12 and 24 hours were specifically measured by ammonia derivatization and analyzed by liquid chromatography-mass spectrometry (LC-MS/MS). Non-compartmental pharmacokinetic analysis was performed.
