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.

Circadian clock and cell cycle are vital cellular programs acting in a timely-regulated, cyclic manner. The two cellular oscillators are coupled in various ways to facilitate biological processes. Here we report CDK9, a kinase belongs to the CDK family in

Irreversible inhibition of transcriptional cyclin-dependent kinases (CDKs) provides a therapeutic strategy for cancers that rely on aberrant transcription; however, lack of understanding of resistance mechanisms to these agents will likely impede their clinical evolution. Here, we demonstrate upregulation of multidrug

More effective treatment options for elderly acute myeloid leukemia (AML) patients are needed as only 25-50% of patients respond to standard-of-care therapies, response duration is typically short, and disease progression is inevitable even with some novel therapies and ongoing clinical
