PCA derivatives have an antioxidant effect on HS68 fibroblast cells. (A) The inhibition of HS68 cell proliferation after treatment with an increased PCA-C(X) concentration for 24 h was shown by cell viability. The data represent three independent tests. # p < 0.001 versus control. *** p < 0.001 (ANOVA test). (B) The antioxidant effect of the PCA derivatives was confirmed by measuring DPPH radical activity. The pictures show that the color of the culture medium was reduced by PCA-C(X). The data are representative of three independent experiments. # p < 0.001 versus control. *** p < 0.001 (ANOVA test).
