gsk-j4

GSK-J4 (GSK J4 HCl) is a cell permeable prodrug of GSK-J1, a dual inhibitor of the H3K27me3 me2 demethylases JMJD3 KDM6B and UTX KDM6A (IC50=8.6 6.6 μM). GSK-J4 induces endoplasmic reticulum stress-related apoptosis.

GSK-3 inhibitor 4 is an orally active and brain-permeable compound that acts as a triple inhibitor of GSK-3, CDK2, and CDK5, with IC50 values of 0.56 nM (GSK-3β), 0.45 nM (GSK-3α), 0.47 μM (CDK2), and 0.68 μM (CDK5). It effectively reduces Tau protein levels and can be used in the study of Alzheimer's disease.

GSK-J4 Hydrochloride (GSK J4 HCl) is a cell permeable, potent and selective histone demethylase(JMJD3 )inhibitor. is an ethyl ester derivative of the GSK-J1 with an IC50 value greater than 50 μM in vitro.

GSK J5 HCl is the hydrochloride form of GSK J5. GSK J5 is an inactive isomer of GSK J4 and a cell-permeable ester derivative of inactive control GSK J2.
