Biochem/physiol Actions

LY2857785 is an ATP-competitive, potent and reversible CDK9/4/8 (IC50 =11 nM/CDK9-CycT, 12 nM/CDK4-CycD1, 16 nM/CDK8-CycC), DYRK2 (IC50 = 44 nM) and FLT3-D835Y (IC50 = 23 nM) inhibitor that significantly reduces cellular RNAP II CTD phosphorylation (U2OS pSer2/pSer5 IC50 =89/42 nM) with good selectivity over a panel of 109 kinase constructs (IC50 = 0.1-1μM/wt FLT3, CDK1/2/3/5/7, PIM1/2; >1 μM/100 kinases). LY2857785 exhibits antiproliferation efficacy in a wide-range cancer cultures (IC50 ∼30 nM-1 μM), and causes AML MV-4-11 xenograft tumor regression in rats (3-9 mg/kg, i.v. infusion Q5Dx5) and mice (8-10 mg/kg, i.v. bolus Q3Dx5) in vivo.
