Background:

CFI-400945 free base is a potent, selective and orally bioavailable PLK4 inhibitor with a Ki and an IC50 of 0.26 nM and 2.8 nM, respectively. PLK4|2.8 nM (IC50)|AURKA|140 nM (IC50)|AURKB/INCENP|98 nM (IC50)|TIE2/TEK|22 nM (IC50)|TRKA|6 nM (IC50)|TRKB|9 nM (IC50)


CFI-400945 (compound 48) shows potent inhibitory activities against a panel of kinases, including PLK4, TRKA, TRKB, AURKA, AURKB/INCENP, and TIE2/TEK, with IC50s of 2.8, 6, 9, 140, 98, 22 nM, and EC50s of 12, 84, 88, 510, 102, 117 nM, respectively. CFI-400945 exhibits growth inhibition effects on breast, lung, ovarian and colon cancer cells. The IC50s (in μM) are as follows: SKBr-3 (5.3), Cal-51 (0.26), BT-20 (0.058), A549 (0.005), OVCAR-3 (0.018), SW620 (0.38), Colo-205 (0.017), and HCT116+/+ (0.004) [1]. CFI-400945 inhibits autophosphorylation of PLK4 at serine 305 with an EC50 value of 12.3 nM in cells overexpressing PLK4. Cancer cells treated with CFI-400945 exhibit effects consistent with PLK4 kinase inhibition, including dysregulated centriole duplication, mitotic defects, and cell death[2].


Oral administration of CFI-400945 (3.0, 9.4 mg/kg) to mice bearing human cancer xenografts results in the significant inhibition of tumor growth at doses that are well tolerated. Increased antitumor activity is observed in PTEN-deficient compared to PTEN wild-type cancer xenografts. The maximum tolerated dose for once-daily administration of CFI-400945 is estimated to be 7.5-9.5 mg/kg[2].
