A cell-permeable tranylcypromine (parnate; Cat. No. 616431) analog that acts as a potent, irreversible inhibitor of lysine specific demethylase 1 (LSD1; IC₅₀ = 70 nM in a HRP-coupled assay using H3K4Me2 peptide substrate). Forms a covalent adduct with flavin adenine dinucleotide (FAD). Shown to cross the blood brain barrier. Exhibits moderate selectivity over amine oxidases MAO-A and MAO-B (IC₅₀ = 0.51 and 2.785 µM, respectively). Displays desirable pharmacokinetic properties (brain/plasma exposure ratio of 88.9), and impairs long-term memory without affecting short-term memory in mice (10 mg/kg, i.p.).
