Protocatechuic Acid
Protocatechuic acid is a polyphenol antioxidant. It has mixed effects on normal and cancer cells in in vitro and in vivo studies. PCA has been reported to induce apoptosis of human leukemia cells, as well as malignant HSG1 cells taken from human oral cavities, but PCA was found to have mixed effects on TPA

Function
Protocatechuic acid (PCA) is a polyphenolic antioxidant known for its diverse effects on both normal and cancerous cells, as demonstrated in various in vitro and in vivo studies. Research has indicated that PCA can induce apoptosis in human leukemia cells and malignant HSG1 cells from the human oral cavity. However, its effects on TPA (12-O-Tetradecanoylphorbol-13-acetate) have been mixed.
