JHDM Inhibitor VII, JIB-04

The (E)-isomer of a cell-permeable pyridine hydrazone compound that acts as a selective inhibitor against Jumonji family histone demethylases (IC₅₀ = 230, 290-320, 340, 435, 445, 855, and 1,100 nM, respectively, against JARID1A/KDM5A, JMJD2D/KDM4D, JMJD2E/KDM4E, JMJD2B/KDM4B, JMJD2A/KMD4A, JMJD3/KDM6B, and JMJD2C/KDM4C, respectively), presumably via catalytic site iron interaction, displaying little or no potency toward 5mC DNA hydroxylase TET1, aurora kinases, HDACs, HIF prolyl hydroxylase PHD2, histone methyltransferases, protein arginine methyltransferases, sirtuins, or the non-jumonji family histone demethylase LSD1/KDM1A. Shown to exhibit anticancer activity against H358 and A549 lunger cancer cells both in cultures in vitro (IC₅₀ = 100 and 250 nM, respectively, in 4 d by MTS assays) and in mice in vivo (via i.p. at 100 mg/kg and p.o. at 55 mg/kg, respectively; 2-3 times per week).
