Sesamol is regarded as a major antioxidant component in the oil with chemoprevention, radioprotective efficacy, anti-antiinflammary, antimutagenic, and antihepatotoxic activities. Sesamol inhibits melanin biosynthesis by down-regulating tyrosinase activity and melanin production via regulation of gene expression of melanogenesis-related proteins through modulation of MITF activity, which promotes phosphorylation of p38 and JNK in melan-a cells.
