IOX 1 (5852-78-8) inhibits the JMJD family of 2-oxoglutarate-dependent histone demethylases. IC50 = 0.12, 0.07, 0.2, 0.3, 0.6, and 1 μM for JMJD3, JMJD1A, JMJD2A, JMJD2E, JMJD2C and UTX respectively.1?A broad spectrum 2-oxoglutarate oxygenase inhibitor, IOX 1 may be used to study hypoxic signaling.1?Cell permeable
