ENMD-2076 is an orally-active, Aurora A/angiogenic kinase inhibitor with a unique kinase selectivity profile and multiple mechanisms of action. ENMD-2076 has been shown to inhibit a distinct profile of angiogenic tyrosine kinase targets in addition to the Aurora A kinase. ENMD-2076 also targets the VEGFR, Flt-3 and FGFR3 kinases which have been shown to play important roles in the pathology of several cancers. ENMD-2076 has shown promising activity in Phase 1 clinical trials in solid tumor cancers, leukemia, and multiple myeloma. ENMD-2076 is currently in a Phase 2 trial for ovarian cancer, and preclinical and clinical activities are ongoing in assessing the compound's applicability for other forms of cancer.
| Cell Experiment | |
|---|---|
| Cell lines | solid tumor cell lines and HUVECs, human leukemia cell lines |
| Preparation method | Cell and proliferative assays Cell lines were routinely tested for mycoplasma and used at low passage numbers (<10). The antiproliferative effect of ENMD-2076 on adherent tumor cell lines was measured by plating 500 cells per well in a 96-well plate and incubating with 9 doses of compound, spanning 0.3 nmol/L to 125 μmol/L, for 96 hours. Cellular proliferation was measured using the sulforhodamine B assay. The leukemia-derived, nonadherent cell lines were assayed by plating 5,000 cells per well in a 96-well plate. The cells were incubated with 9 doses of compound, spanning 0.3 nmol/L to 125 μmol/L, for 48 hours and then survival was assayed using the Alamar Blue reagent (M10350) according to the manufacturer’s instructions. To measure the effect of ENMD-2076 on VEGF- and fibroblast growth factor (FGF)-induced proliferation of human umbilical vein endothelial cell (HUVEC), cells were serum starved for 6 hours, then treated with ENMD-2076 free base, and stimulated with 5 ng/mL bFGF or 25 ng/mL VEGF for 72 hours. Cell proliferation was measured using WST-1 according to the manufacturer’s instructions. |
