RK-701 (RK701) is a potent, highly selective and reversible histone lysine methyltransferases G9a and G9a-like protein (GLP) inhibitor with IC50 of 23-27 nM and 53 nM, respectively.
RK-701 is a histone H3 substrate-competitive inhibitor, displays >1000-fold selectivity against other methyltransferases.
In contrast to G9a inhibitors such as UNC0638, RK-701 shows essentially no cytotoxic effect on the viability of normal cells, including rat myoblast cell line H9c2 and HUDEP-2 cells.
RK-701 treatment (0.3 uM) for primary human CD34+ hematopoietic cells significantly increased γ-globin mRNA expression, the level of HbF expression, and the percentage of HbF-expressing cells without affecting cell viability or erythroid differentiation.
RK-701 induced fetal globin expression both in human erythroid cells and in mice.
RK-701 selectively upregulates BGLT3 by inhibiting the recruitment of two major γ-globin repressors in complex with G9a onto the BGLT3 gene locus through CHD4, a component of the NuRD complex.
RK-701 is a promising lead compound for the development of therapeutic agents for sickle cell disease (SCD), and a excellent chemical tool thus far for investigating the physiological roles of G9a both in vitro and in vivo.
