Biological Activity:

KDM5-C49 is a potent and selective inhibitor of Jumonji AT-Rich Interactive Domain 1 (JARID1) histone demethylases. It has IC50 ~40 nM, 160 nM and 100 nM for KDM5A, KDM5B and KDM5C respectively. It has >100-fold selectivity over KDM4 and KDM6 etc. KDM5-C49 occupies the aKG-. The highly polar carboxylate group of KDM5-C49 restricts its cellular permeability, so it has IC50 >1 µM for inhibiting demthylation of H3K4 in U2OS human osteosarcoma cell line and in human breast adenocarcinoma MCF7 tumor cell proliferation assay. Therefore KDM5-C70 was developed as a pro-drug, masking the polarity of the acid group of the KDM5-C49, for cellular assays and in vivo use.

How to Use:

In vitro: KDM5-C49 was used at 1-10 µM in vitro.
In vivo: n/a
