Next generation precision lysine-specific histone demethylase 1A (LSD1) covalent inhibitors which selectively block LSD1 enzyme activity by forming a compact N-formyl-FAD adduct have been developed, but the mechanism of adduct formation was unclear. Here, the authors show that the covalent inhibitor-FAD adduct undergoes a Grob fragmentation and elucidate the structure-activity relationships that promote this transformation.
