Norartocarpetin is a potent tyrosinase inhibitor exhibiting significant antibrowning properties useful for food system research, with an IC50 of 0.47 μM. Furthermore, it demonstrates substantial anticancer activity specifically in lung carcinoma cells (NCI-H460), achieving an IC50 of 22 μM. The antiproliferative effects of Norartocarpetin are achieved through targeting the Ras/Raf/MAPK signaling pathway, inducing mitochondrial-mediated apoptosis, facilitating S-phase cell cycle arrest, and inhibiting cell migration and invasion in human lung carcinoma cells.
