Figure Lengend Snippet: Effects of 10E-PDA on inhibiting melanogenesis in α-MSH-stimulated B16F10 melanoma cells. ( a ) B16F10, ( b ) HS68, and ( c ) HaCaT cells were treated with increasing concentrations of 10E-PDA (1–100 μM) for 24 h, after which cell viability was assessed (n = 4 per group). ( d , e ) B16F10 cells were pretreated with different concentrations of 10E-PDA (1–15 μM) or kojic acid (30 μM) for 1 h, followed by exposure to α-MSH (500 nM) for 6 days to measure melanin content ( d ) or for 3 days to examine tyrosinase activity ( e ). In both panels, the white bar represents the untreated control group without α-MSH stimulation, the black bar represents the α-MSH-stimulated control group, and the dark gray bars indicate the 10E-PDA-treated groups under α-MSH stimulation. In panel ( e ), the light gray bar represents the positive control group treated with kojic acid under α-MSH stimulation. Data are shown as mean ± SEM. ### p < 0.001 compared with the untreated control group, and * p < 0.05, ** p < 0.01, *** p < 0.001 compared with the α-MSH-treated group.
