GallnutsActive ingredientsAction related to anticancerReferences

Galla TurcicaPurpurogallinInhibit the tyrosine-specific protein kinase of the human oncogene product epidermal growth factor receptor[22]

Galla Turcica50% ethanol extractProtect against oxidative stress-induced liver injury[23]

Galla ChinensisGallic acidIncrease the activities of phase II xenobiotic-metabolizing enzyme and decrease the activities of phase I xenobiotic-metabolizing enzyme, and thus decrease tumor incidence[24]

Galla ChinensisGallic acidIncrease p53 and NF-κB, decrease I-κB protein, and thus induce apoptosis and inhibit cell viability in U937 cells[25]

Galla ChinensisGallic acidUpregulate p27(Kip1) level via disruption of p27(Kip1)/skp2 complex and the consequent degradation of p27(Kip1) and lead to G2/M phase arrest of MCF-7 cells[26]

Galla Chinensis1,2,3,4,6-Penta-O-galloyl-β-D-glucoseRegulate the expression of genes involved in cancer pyruvate metabolism, glycolysis/gluconeogenesis, and tyrosine metabolism[27]

Galla ChinensisGallic acidDownregulate expression of COX-2 and stathmin and inhibit the proliferation of 5-8F cells[28]

Galla Chinensis1,2,3,4,6-Penta-O-galloyl-β-D-glucoseEnhance cytotoxicity and PARP cleavage in cisplatin-treated Caki-2 cells[29]

Galla ChinensisGallic acidSuppress the matrix metalloproteinase-2/-9, protein kinase B and C signaling, and thus inhibit migration and invasion of U-2 OS cells[30]

Galla ChinensisEther fractionInhibit the proliferation of U251[31]

Galla TurcicaAqueous extractShow similar acute, chronic toxicity, and mortality to that of control[32]

Galla ChinensisEthyl acetate extractInhibit the activities of epidermal growth factor receptor[33]

Galla Chinensis1,2,3,4,6-Penta-O-galloyl-β-D-glucoseInhibit human lactic acid dehydrogenase-A and attenuate proliferation of MDA-MB-231 cells[34]

Galla ChinensisWater extractDo not produce significant acute and chronic toxicity until overdose (3 times higher than that of the recommended dose), no side effects to rats in central nervous system, cardiovascular system, and respiratory system[35]
