CYC-116 is a potent aurora A and aurora B inhibitor with K_is of 8 and 9 nM, respectively.

CYC-116 also inhibits VEGFR2, Src, Lck AND FLT3 with with K_is of 44, 82, 280, 44 nM, respectively. CYC-116 may have broad-spectrum antitumor activity. CYC-116 shows potent antiproliferative activity against cancer cell lines with with IC₅₀s of 0.599, 0.59, 0.241, 0.34, 0.725, 1.375, 0.471, 0.034, 0.372, 0.681, 0.151, 1.626, 0.775, 0.308, 0.110, 0.09 for MCF7, HeLa, Colo205, HCT-116, HT29, K562, CCRF-CEM, MV4-11, HL60, NCI-H460, A2780, BxPC3, HuPT4, Mia-Paca-2, Saos-2, Messa cells. Treatment with 1.25 μM CYC-116 for 7 h results in complete inhibition of histone H3 phosphorylation in HeLa cell lysates^[1].

Oral administration of CYC-116 at dose levels of 75 and 100 mg/kg q.d. causes tumor growth delays of 2.3 and 5.8 days, which translates into specific growth delays of 0.32 and 0.81, respectively. The mean relative tumor volumes of mice receiving CYC-116 at both dose levels are less than those of vehicle-treated mice for the duration of the study period. At 100 mg/kg po q.d., the reduction in growth is statistically significant on days 6 and 9^[1].

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)), and 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 MgCl₄, 100 μM ATP, with 18.5 kBq γ-³²P-ATP per well) and incubated at 30°C for 30 min before terminating by the addition of 25 μL of 75 mM H₃PO₄. Aurora B kinase assays are performed as for aurora A except that prior to use, aurora B is activated in a separate reaction at 30°C for 60 min with inner centromeres protein^[1].
