GSKJ1 is a selective and potent histone demethylase inhibitor (GSK-J1) that has significant activity (IC50 60 nM for human JmjD3) in vitro and in cells using an ester derivative (GSK-J4: 1 µM < IC50 < 10 µM; e.g. 9 µM in primary human macrophages). The pyridine regio-isomer GSK-J2 displays significantly less on-target activity (IC50 > 100 µM for human JmjD3) and thus can be used as control for target effects in vitro, and as ester derivative (GSK-J5) in cells. Recent data has shown that GSK-J1 also shows some activity (IC50 950 nM for Jarid1b, IC50 1.76 uM for Jarid1c) against H3K4me3/2/1 demethylases.

How to use

In Vitro:

GSK-J1 inhibits TNF-α production by human primary macrophages in an H3K27-dependent manner. GSK-J1 inhibits the demethylase activity of KDM5C with 8.5-fold increased potency compared with that of KDM5B at 1 mM α-ketoglutarate, with IC50 of 11 μM and 94 μM, respectively.GSK-J1 is selective for H3K27 demethylases of the KDM6 subfamily and specifically binds to endogenous JMJD3.
