Abstract
Objective: Breast cancer is a malignant disease of women most often found after cervical cancer in Indonesia. Increased levels of free radicals can cause DNA damage, which could lead to malignancy; this can play role in breast cancer etiopathogenesis. The present research was conducted to determine the activity of catechins as antioxidants and their potential efficacy in inhibiting breast cancer malignancy.
Methods: The research was done by examining the antioxidant and free radical scavenging activity including 1,1-diphenyl-2-picryl-hydrazyl (DPPH), the value of superoxide dismutase (SOD), and assays in breast cancer cell lines (T47D, MCF7). The cytotoxic potency was determined by the MTS (3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium) assay.
Results: The highest DPPH scavenging activity is presented by (-)-epigallocatechin (EGC) and the lowest by gallo catechins (GC). The highest SOD value were reached with EGC at 500 g/ml, followed by (-)-epicatechin gallate (ECG) at 125 g/ml, and GC at 31.25 g/ml concentrations. The highest cytotoxic activity in T47D cell line for 24 and 48 h incubation was exhibited by (-)-gallocatechin gallate (GCG). The greatest cytotoxic activity in MCF7 cell line for 24 h was presented by (-)-epigallocatechin gallate (EGCG), and for 48 h incubation by (+)-catechin (C).
Conclusion: Catechins have high antioxidant activities proven by both DPPH scavenging and SOD activities. They possess higher anticancer action on T47D than on MCF7 cell line.
