Abstract

Histone demethylase LSD1 is a flavin-dependent amine oxidase that catalyzes the oxidative removal of one or two methyl groups from the methyl-lysine-4 side chain of histone H3. We have designed and synthesized two peptide-based inhibitor analogues that block LSD1. One of these inhibitors, compound 1, contains a propargylamine functionality and shows time-dependent inactivation of LSD1. Peptide substrate, diMeK4H3-21, protected LSD1 against inactivation by 1 in a concentration-dependent fashion. Mass spectrometric analysis showed that 1 forms a covalent interaction with FAD. Compound 1 did not detectably inhibit monoamine oxidase B in the concentration range studied. Compound 1 is thus a selective, mechanism-based inactivator of LSD1 and is likely to serve as a useful tool in the study of histone modifications and chromatin remodeling.
