Objective:To investigate the effects of syringic acid on HEK 293 and HepG2 cells in the absence and presence of exogenous Cu(Ⅱ)and Fe(Ⅱ)***:The antiproliferative effects of syringic acid on HEK 293 and HepG2 cells in the absence and presence of exogenous Cu(Ⅱ)and Fe(Ⅱ)ions were examined by MTT ***,colony-forming,reactive oxidative species(ROS)generation,apoptosis induction,autophagy,mitochondrial membrane potential,and mitochondrial mass were ***:At 24 and 72 h,no significant differences were observed in the viability of HepG2 cells between the control and syringic acid+Fe(Ⅱ)***,exposure of HepG2 cells to syringic acid+Cu(Ⅱ)for 72 h reduced the cell viability ***,ROS formation,induction of apoptosis,and autophagic vacuoles were significantly increased in HepG2 cells without marked changes in mitochondrial membrane potential and mitochondrial ***,syringic acid+Cu(Ⅱ)reduced the plating efficiency and surviving fraction ***:The combination of syringic acid with Cu(Ⅱ)was toxic to cancer cells and showed pro-oxidant *** addition,this combination induced autophagy in cancer cells with less cytotoxic effects on normal cells,which is a potential candidate for the development of novel therapeutics towards cancer.
