NRAS and melanoma: Magnolol‐induced cell death has been observed in two melanoma cell lines, A375‐S2 and A431, but at a high concentration (100 μmol L−1).11 In contrast, we have found that 30 μmol L−1 magnolol in monotherapy and 25 μmol L−1 in combination therapy were sufficient to induce cell death in BRAF‐ and NRAS‐mutant melanoma cells.
