Protective effect of benzylideneacetophenone derivatives (JC1-JC6) on H₂O₂-induced cytotoxicity among SK-N-MC cells. SK-N-MC cells were pretreated with 20 µM of JC1-JC6 for 3 h, and then exposed to 300 µM H₂O₂ for further 24 h and 48 h. Cell viability was evaluated by MTT assay. Catechin was used as the positive control. Data were expressed as percent of values of untreated control cells. Each value represents the mean ± SD (n = 3). ^*Significantly different from control cells (P<0.05); ^#Significantly different from H₂O₂-treated cells (P<0.05).
