EPZ5676

SKU: orb1226408

Description

EPZ-5676 is an S-adenosyl methionine (SAM) competitive inhibitor of protein methyltransferase DOT1L with Ki of 80 pM, demonstrating >37,000-fold selectivity against all other PMTs tested, inhibits H3K79 methylation in tumor. Phase 1.(In Vitro):Pinometostat (EPZ-5676) inhibits H3K79me2 with IC50 values of 3 nM and 5 nM in MV4-11 and HL60 cells, respectively. Pinometostat (EPZ-5676) is a potent inhibitor of MV4-11 proliferation with an IC50 value of 3.5 nM. Pinometostat (EPZ-5676) induces a synergistic and durable antiproliferative effect, increases expression of differentiation markers and apoptosis as single agent, and demonstrates combination benefit in combination with AML standard of care drugs in MLL-r cells.(In Vivo):Pinometostat (EPZ-5676) (70 mg/kg, i.p.) causes complete and sustained regression in a rat xenograft model of MLL-rearranged leukemia. Pinometostat (EPZ-5676) (70, 35 mg/kg, i.v.) reduces HOXA9 and MEIS1 mRNA levels of tumors taken from rats, and reduces MLL-fusion target gene expression in vivo.
