Biological Activity for IOX 1

IOX 1 is a histone demethylase JMJD inhibitor (IC50 values are 0.12, 0.17, 0.2, 0.3, 0.6 and 1 μM for JMJD3, JMJD1A, JMJD2A, JMJD2E, JMJD2C and UTX respectively). Cell permeable; it inhibits JMJD2A-mediated H3K9me3 demethylation in HeLa cells. IOX 1 suppresses IL-17 expression in mouse and human CD4+ T cells by targeting TET2. It also reduces infiltration of Th17 cells in an in vivo model of intraocular inflammation.
