Used in the treatment of certain cancers, particularly in clinical trials targeting acute myeloid leukemia (AML). It functions as a selective inhibitor of lysine-specific demethylase 1 (LSD1), which plays a role in gene regulation and cancer progression. By inhibiting LSD1, it helps to reactivate tumor suppressor genes and induce differentiation in cancer cells. This makes it a promising therapeutic agent for patients with relapsed or refractory AML. Ongoing research is exploring its efficacy in combination with other treatments to enhance anti-cancer effects.
