Mechanism of Action

Features	An orally bioavailable, small molecule inhibitor of Aurora kinase/VEGFR2.
Targets/IC₅₀/Ki	Aurora A (Cell-free assay) 8 nM(Ki) Aurora B (Cell-free assay) 9 nM(Ki) VEGFR2 (Cell-free assay) 44 nM(Ki) FLT3 (Cell-free assay) 44 nM(Ki) CDK2/CyclinE (Cell-free assay) 0.39 μM(Ki) CDK9/CyclinT (Cell-free assay) 0.48 μM(Ki) p70 S6K (Cell-free assay) 0.54 μM(Ki)
In vitro	The most Aurora-selective CYC116 shows inhibitory effect on Aurora A and B kinases 50-fold more potently than any of the CDKs assayed. This compound is initially screened against a panel of human leukemia and solid tumor cell lines using an MTT antiproliferative assay. The results show that it has broad-spectrum antitumor activity and shows specific cytotoxicity against the acute myelogenous leukemia cell line MV4-11 with IC50 of 34 nM. In addition, anti-proliferative activity of this chemical is found to be associated with Aurora A and B modulation such as, inhibition of Aurora autophosphorylation, reduction of histone H3 phosphorylation, polyploidy, followed by cell death, resulting from a failure in cytokinesis.
Kinase Assay	Kinase Assays
Kinase Assay	Aurora A kinase assays are performed using a 25 μL reaction volume (25 mM β-glycerophosphate, 20 mM Tris/HCl, pH 7.5, 5 mM EGTA, 1 mM DTT, 1 mM Na₃VO₄, 10 μg of kemptide (peptide substrate)). Recombinant Aurora A kinase is diluted in 20 mM Tris/HCl, pH 8, containing 0.5 mg/mL BSA, 2.5% glycerol, and 0.006% Brij-35. Reactions are started by the addition of 5 μL Mg/ATP mix (15 mM MgCl₂, 100 μM ATP, with 18.5 kBq γ-³²P-ATP per well) and incubated at 30°C for 30 minutes before termination with 25 μL of 75 mM H₃PO₄. Aurora B kinase assays are performed like Aurora A except that prior to use, Aurora B is activated in a separate reaction at 30°C for 60 minutes with inner centromere protein.
In vivo	Mice bearing subcutaneous NCI-H460 xenografts are given CYC116 orally for 5 days, at dose levels of 75 and 100 mg/kg q.d. It leads to tumor growth delays of 2.3 and 5.8 days, which translated into specific growth delays of 0.32 and 0.81, respectively.
