Protocatechuic acid Function and usage
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-induced mouse skin tumours. Depending on the amount of PCA and the time before application, PCA could reduce or enhance tumour growth. Similarly, PCA was reported to increase proliferation and inhibit apoptosis of neural stem cells.
