Fig. 1. Effects of sulforaphene (SFEN) on HaCaT cell viability. (A) Chemical structure of SFEN. (B) MTT assay results showed that SFEN did not exhibit cytotoxicity until 20 μM concentration. All graphs represent the means ± SEM (n = 3). Asterisks indicate a significant inhibition by SFEN compared with non-treated group (**p < 0.01) using Student’s t-test.
