    The inhibition of Aurora kinases in order to arrest mitosis and subsequently inhibit tumor growth via apoptosis of proliferating cells has generated significant discussion within the literature. We report a novel class of Aurora kinase inhibitors based upon a phthalazinone pyrazole scaffold. The development of the phthalazinone template resulted in a potent Aurora-A selective series of compounds (typically >1000-fold selectivity over Aurora-B) that display good pharmacological profiles with significantly improved oral bioavailability compared to the well studied Aurora inhibitor VX-680.
