IC50: 0.0017, 0.021 for Aurora-B/INCENP and Aurora-A/TPX2, respectively
Protein kinases Aurora A, B, and C play crucial roles during mitosis and cell division, are frequently elevated in cancer, and represent attractive targets for therapeutic intervention. TAK-901 is a novel, multitargeted Aurora B kinase inhibitor derived from a novel azacarboline kinase hinge-binder chemotype.
In vitro: TAK-901 exhibited time-dependent, tight-binding inhibition of Aurora B, but not Aurora A. Consistently, TAK-901 suppressed cellular histone H3 phosphorylation and induced polyploidy. In various human cancer cell lines, TAK-901 inhibited cell proliferation with effective concentration values from 40 to 500 nmol/L. TAK-901 potently inhibited only a few kinases other than Aurora B in intact cells, including FLT3 and FGFR2 .
In vivo: In rodent xenografts, TAK-901 exhibited potent activity against multiple human solid tumor types, and complete regression was found in the ovarian cancer A2780 model. In vivo biomarker studies showed that TAK-901 induced PD responses consistent with Aurora B inhibition and correlating with retention of TAK-901 in tumor tissue. .
Clinical trials: An open-label, dose escalation, phase I study has been conducted to identify the MTD and PK profile of TAK-901 in adult patients with advanced solid tumors or lymphoma.
