Purity ~96% (HPLC). A methyl ester prodrug of in vitro active N-hydroxybutenoic acid compound that is shown to preferentially induce hypermethylation of histone proteins (EC50 for H3K4me3 and H3K9me3=10.3 and 8.6uM in KYSE150 cells, and 6.7 and 6.3uM in MCF7 cells, respectively), and arrests cell growth. Acts as a selective inhibitor of Jumonji domain-containing histone demethylases (JHDMs) over prolyl hydroxylases (PHDs), and prevents myogenesis through inhibition of H3K27 demethylase UTX in C2C12 cells at 2uM. Formula: C28H31N3O6 Solubility: DMSO Molecular Weight: 505.6
