Luteoline is a flavonoid compound and an effective Nrf2 inhibitor. It has anti-inflammatory and anti-cancer properties, including inducing apoptosis and cell cycle arrest in a variety of cancer cell lines (including human non-small lung cancer cells), as well as inhibiting metastasis and angiogenesis.
