Background

LEE011 (NVP-LEE011) is a highly specific inhibitor of CDK4/CDK6 and functions via decreasing in phosphorylated RB and FOXM1 [1]. When tested with 17 human neuroblastoma cell lines, 12 of them were sensitive to LEE011 treatment with mean IC50=306±68 nM [2].
CDK4/6 could increase G1-S phase cell cycle progression and ultimately cellular proliferation via phosphorylating tumor suppressor protein RB. CDK4/6 signaling also could senescence suppression by regulating FOXM1 transcription[3]. Numerous studies have shown that over-expression of CDK4/CDK6 correlated with tumorigenesis and disease progression [4].
LEE011 is a novel inhibitor for CDK4/CDK6. When subjected to human liposarcoma cell lines, treated with LEE011 could dramatically decrease cell growth via arresting cell cycle G0-G1 [1]. In 12 of 17 human neuroblastoma-derived cell lines, treatment with LEE011 could significantly reduce cell proliferation [2].
In a mouse model with human liposarcoma xerography, continued treating the mouse with LEE011 orally could inhibit tumor growth or induce regression without detrimental effects on mouse weight [1]. In mice xerography with neuroblastoma cells, treated with LEE011 could inhibit the tumor growth [2].
