Cell viability (A) and proliferation (B) upon 24-h treatment with DHPs followed by 1-h exposure to H₂O₂. Results are expressed as a percentage of non-treated control. Statistically significant differences between—(a) DHPs alone vs. non-treated control (pale grey bars) or (b) DHPs treated vs. treated control (dark grey bars) are shown as follows: a*/b* p < 0.05; a⁺/b⁺ p < 0.005; a^#/b^# p < 0.0005. Values are given as mean ± standard deviation, n = 4.
