| Application: | GSK-J4 has been used to study the effect of KDM2B (Jumonji (JmjC) domain histone 3 lysine 36 (H3K36) di-demethylase) inhibition on the survival and DNA repair potential of glioblastoma cells. It has also been used in sulforhodamine B (SRB) cell growth assay and cell viability assay. |
| Biochem/physiol Actions: | GSK-J4 is a potent selective jumonji H3K27 demethylase inhibitor. |
| Biochem/physiol Actions: | GSK-J4 is cell permeable prodrug rapidly hydrolysed by macrophage esterases to GSK-J1, a potent selective jumonji H3K27 demethylase inhibitor. Jumonji C domain-containing histone demethylases (JHDMs) are Fe(II) and α-ketoglutarate dependent enzymes that oxygenate methylated histone lysine residues and thereby cause their demethylation. GSK-J1 is selective for the KDM6 subfamily members JMJD3 and UTX with an IC50 of 60 nM in a JMJD3 assay, and is inactive against other demethylases of the JMJ family and over 100 tested kinases and histone deacetylases. The prodrug GSK-J4 inhibited TNF-α production with an IC50 of 9 μM in LPS-stimulated human macrophages and blocked the production of TNF-α by macrophages derived from patients with rheumatoid arthritis.
