CCB02 perturbs CPAP PN2-3-tubulin interaction with an IC50 of 0.441 μM in a PN2-3 CPAP-GST pull-down assay.
CCB02 shows no inhibition on the cell cycle- and centrosome-related kinases, or the phosphorylation status of Aurora A, Plk1, Plk2, CDK2, and CHK1.
CCB02 (0.1-15 μM, 72 hours) inhibits the proliferation of cancer cells with extra centrosomes, IC50s are 0.86-2.9 μM.
CCB02 activates spindle assembly checkpoint, induces PCM proteins recruitment to centrosomes, and enhances microtubule nucleation activities of centrosomes.
