JIB-04 (NSC 693627) is a pan-selective Jumonji histone demethylase inhibitor.

(Z)-JIB-04 (NSC 693627) is an isomer of JIB-04.

Compound A5b, also known as JMJD3 HDAC-IN-1, is a dual inhibitor that targets both JMJD3 (Jumonji domain-containing protein demethylase 3) and HADC1 (histone deacetylase, IC50 = 16 nM). It induces hypermethylation of histone H3K27 and hyperacetylation of H3K9, while also promoting apoptosis through the cleavage of caspase-7 and PARP. This compound has demonstrated the ability to effectively inhibit cancer cell cloning, migration, and invasion [1].

JHDM-IN-1 (Compound 1), a Jumonji C domain-containing HDMs (JHDM) inhibitor, exhibits IC50s of 3.4 μM against JMJD2C, 4.3 μM against JMJD2A, 5.9 μM against JMJD2E, 10 μM against PHF8, and 43 μM against JMJD3, showcasing its inhibitory effectiveness across a spectrum of JHDM enzymes [1].

E67-2, a derivative of E67, is a low-toxicity, selective inhibitor of the KIAA1718 Jumonji domain. It has an IC 50 value of 3.4 μM. E67-2 specifically inhibits the Jumonji demethylase for histone H3 lysine 9 (H3K9) and histone H3 lysine 4 (H3K4) demethylase.

Methylstat is a methyl ester prodrug of a Jumonji C domain-containing histone demethylase (JMJD) inhibitor that has favorable cell permeability. The free acid of methylstat inhibits JMJD2A, JMJD2C, JMJD2E, PHF8, and JMJD3 with IC50 values of approximately 4.3, 3.4, 5.9, 10, and 43 μM, respectively, in an in vitro assay. Methylstat inhibits growth of the JMJD2C-sensitive esophageal cancer cell line KYSE150 with a GI50 of 5.1 μM, whereas the free acid of methylstat did not inhibit cell growth up to 100 μM. Methylstat induces histone hypermethylation at multiple sites in a concentration-dependent manner (EC50 for H3K4me3 and H3K9me3 = 10.3 and 8.6 μM in KYSE150 cells and 6.7 ad 6.3 μM in MCF-7 cells, respectively).

Prohexadione is a plant growth regulator. It inhibits the gibberellin plant hormone biosynthesis enzyme 3β-hydroxylase when used at concentrations of 0.1, 1, and 10 mM. It reduces the shoot length of peanut plants when applied at 0.5, 1.5, and 4.5 kg hectare. Prohexadione also inhibits jumonji domain-containing 2A (JMJD2A) demethylase when used at a concentration of 1 mM and induces the differentiation of mouse neurospheres into neurons at 1, 1.5, and 2 mM. Formulations containing prohexadione have been used as plant growth regulators in agriculture.

PBIT inhibits JARID1B histone demethylase (IC50 of about 3 μM). PBIT also inhibits JARID1A and JARID1C (IC50s of 6 μM and 4.9 μM, respectively). PBIT is a specific inhibitor of the Jumonji AT-rich Interactive Domain 1 (JARID1) enzymes .

ML324(IC50=920 nM) is a specific inhibitor of jumonji histone demethylase (JMJD2).
