Biological Activity: Tranylcypromine inhibits LSD1 with an IC50 value of 20.7 µM and a Ki value of 242.7 µM. It also irreversibly inhibits MAO A and MAO B with IC50 values of 2.3 and 0.95 µM and Ki values of 101.9 and 16 µM, respectively.
CAS Number: 13492-01-8
Description: Tranylcypromine (2-PCPA) is an irreversible inhibitor of LSD1 histone demethylase and monoamine oxidases (MAO). The inhibitor targets monoamine oxidases A and B and has been used as a chemical scaffold to design new demethylase inhibitors. Tranylcypromine has been shown to increase Histone H3 lysine 4 (H3K4) methylation in P19 embryonal carcinoma cell.
