Melatonin could not protect against cell damage at low concentrations ( i.e ., <50 μM) but showed significant protection with an increasing trend at concentration ≥50 μM ( p < 0.05).

Although the melatonin derivatives (BBM and EBM) showed no toxicity to cells in the cytotoxicity experiment which was performed in the presence of FBS in culture medium, a decreasing trend in the percentage of protective effects of BBM on H 2 O 2 -damaged cells was observed as concentrations increased.
