JQEZ5 is a potent and selective EZH2 lysine methyltransferase inhibitor. JQEZ5 SAM-competitively inhibits polycomb repressive complex 2 (PRC2) with an IC 50 of 80 nM. JQEZ5 has anti-tumor effects.

Solid

EZH2

JQEZ5 inhibits enzymatic functionality of PRC2 with a biochemical IC50 of 80nM. JQEZ5 exhibits S-adenosyl methionine (SAM)-competitive inhibition of PRC2.
H661 cells treated with increasing concentrations of JQEZ5 demonstrate acutely reduced levels of H3K27me3 without affecting H3K27 mono- or di-methylation. JQEZ5 suppresses the proliferation of EZH2-overexpressing H661 and H522 cells after treatment for 4 days without affecting the proliferation of cell lines that were deemed insensitive to EZH2 knockdown. has not independently confirmed the accuracy of these methods. They are for reference only.

JQEZ5 (75 mg/kg; intraperitoneal injection; daily; for 3 weeks) treatment exhibits rapid and pronounced tumor regression over the three week treatment course. And H3K27me3 levels are largely reduced with treatment further confirming the on-target effect of JQEZ5 in mice. has not independently confirmed the accuracy of these methods. They are for reference only.
