GSK2879552 (1401966-65-5, free base) is potent, selective, and irreversible inhibitor of Lysine Demethylase 1 (LSD1) via covalent modification of the LSD1 cofactor FAD (Ki = 1.7 µM). It is selective for LSD1 over the closely related LSD2, MAO-A, MAO-B, and the FAD dependent enzymes D-amino acid oxidase and glutathione reductase. Tested against a panel of 165 cancer cell lines, GSK2879552 inhibited the proliferation of 9 small cell lung carcinoma lines and 20 AML cell lines.
