This invention discloses a novel application of undecanoic acid in inducing ferroptosis in laryngeal cancer cells and in the preparation of anti-laryngeal cancer drugs. For the first time, it was discovered that the known compound undecanoic acid can specifically target the mitochondria of laryngeal cancer cells, inducing mitochondrial structural damage and dysfunction. This, in turn, activates the ferroptosis pathway through multiple mechanisms, including increasing intracellular ferrous ion accumulation, increasing lipid peroxide levels, downregulating GPX4 / SLC7A11 expression, and upregulating ACSL4 expression, thereby effectively inhibiting the proliferation of laryngeal cancer cells. Based on this mechanism, this invention provides a pharmaceutical composition with undecanoic acid as the active ingredient, and its combined application with platinum-based drugs (such as cisplatin). This combined treatment exhibits a significant synergistic effect, particularly overcoming the platinum resistance of laryngeal cancer cells. This invention provides a novel drug selection and combination therapy strategy for the treatment and prevention of laryngeal cancer and precancerous lesions.
