PHA-680632 is an aurora kinase inhibitor with IC₅₀s of 27, 135 and 120 nM for aurora A, B and C, respectively.

PHA-680632 shows 30- to 200-fold higher IC₅₀s of FLT3, LCK, PLK1, STLK2, VEGFR2, and VEGFR3 compared with Aurora A. PHA-680632 has potent antiproliferative activity in a wide range of cell types. The IC₅₀s are 0.32, 0.41, 0.06, 1.17, 0.56, 0.62, 0.29, 0.11, 1.56, 0.62, 0.07, 0.13, 0.41 μM for C33A, HeLa, HCT116, HT29, LOVO, A549, MCF7, A2780, U2OS, DU145, U937, HL60, NHDF. PHA-680632 can cause polyploidy in tumor cells. PHA-680632 cell treatment induces phenotypes similar to Aurora A or B depletion^[1]. PHA680632, inhibits colony formation in different cancer cell lines and induced polyploidy. Aurora-A inhibition by PHA680632 enhances radiation response in cancer cells, especially in p53-deficient cells^[2].

PHA-680632 suppresses tumor growth in animal models. PHA-680632 treatment at 45 mg/kg dose results in 85% of TGI without signs of toxicity in the HL60 human acute myelogenous leukemia xenograft model. PHA-680632 treatment at 60 mg/kg i.v. b.i.d. for 5 days results in 78% of TGI without signs of toxicity in the A2780 human ovarian carcinoma model^[1]. PHA680632 in association with radiation leads to an additive effect in cancer cells, especially in the p53-deficient cells, but does not act as a radiosensitiser^[2].

Inhibition of kinase activity by PHA-680632 is assessed using a scintillation proximity assay format. In this assay, the biotinylated substrate is transphosphorylated by the kinase in presence of ATP traced with γ³³-ATP. The phosphorylated substrate is then captured using streptavidin-coated scintillation proximity assay beads and the extent of phosphorylation is evaluated by β-counter after a 4-hour rest for the floatation of the beads on a dense 5 M CsCl solution. In particular a peptide derived from the Chocktide sequence (LRRWSLGL) is used as substrate for Aurora A, whereas the optimized peptide Auroratide1 is employed for Aurora B and C. The assay is run in a robotized format on 96-well plates. The potency of the compound toward Aurora kinases and 29 additional kinases belonging to our Kinase Selectivity Screening panel is evaluated and the relevant IC₅₀s are determined^[1].

Cells are seeded at different densities ranging from 5,000 to 15,000 cm² in 24-well plate with the appropriate complete medium. After 24 hours, plates are treated with PHA-680632 and incubated for 72 hours at 37°C in 5% CO₂ atmosphere. At the end of incubation time, cells are detached from each plate and counted using a cell counter. IC₅₀s are calculated using percentage of growth versus untreated control^[1].

Mice: Tumour xenograft mice are randomly allocated into four groups (six mice per group): A, control; B, IR alone, 8 Gy in 1 day; C, PHA-680632 alone, 40 mg/kg, b.i.d., for 4 days; D, same dose of PHA-680632 combined with IR (24 h after the first administration of PHA680632, similar schedule as IR alone) for 4 days. Drug or vehicle control (same volume of 20% Tween-80 in 5% glucose solution) is administered intraperitoneally (i.p.). The tumour size is measured twice a week using an electronic caliper. Follow-up of individual mice is conducted. The tumour volume is estimated from 2D tumour measurements^[2].
