Namoline is a gamma-pyrone compound that functions as a selective and reversible inhibitor of Lysine-specific demethylase 1 (LSD1) with an IC50 of 51 uM in an HRP-coupled enzymatic assay. By impairing LSD1 demethylase activity, Namoline effectively inhibits cell proliferation. Due to its characteristics, Namoline holds promise for research pertaining to androgen-dependent prostate cancer.
