CCT 137690

CCT 137690 is a potent and orally available aurora kinase inhibitor with IC50s of 15, 25, and 19 nM for aurora A, B and C, respectively.

Aurora A:15 nM (IC50)

Aurora B:25 nM (IC50)

Aurora C:19 nM (IC50)

CCT 137690 displays antiproliferative activity in a range of human tumor cell lines, including SW620 colon carcinoma (GI50=0.30 μM) and A2780 ovarian cancer cell line (GI50=0.14 μM). CCT 137690 inhibits in vitro phosphorylation of histone H3. CCT 137690 is a moderate inhibitor of the hERG ion-channel (IC50=3.0 μM)[1]. CCT137690 efficiently inhibits histone H3 and TACC3 phosphorylation (Aurora B and Aurora A substrates, respectively) in HCT116 and HeLa cells. Continuous exposure of tumour cells to the inhibitor causes multipolar spindle formation, chromosome misalignment, polyploidy and apoptosis[2].

CCT 137690 slows the growth of the SW620 xenografts with no observed toxicity[1]. CCT 137690 significantly inhibits tumour growth in a transgenic mouse model of neuroblastoma (TH-MYCN) that overexpresses MYCN protein and is predisposed to spontaneous neuroblastoma formation[2].

Cells are plated in 96-well plates at 3,000 cells per well and are treated with a range of 0 to 25 mol/L of CCT137690 for 72 h. Cell proliferation assays are performed by colorimetric 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT)[2].

Mice: Animals are randomized into two groups, group 1: treatment with 100 mg/kg CCT137690 n=4 or group 2: vehicle control n=4. Treatment is administered via oral gavage twice daily. Tumour volumes are measured at day 0, 3 (48 hours after treatment started), 7 and 10 using 1H MRI[2].
