    Several potent Aurora kinase inhibitors derived from 5H-benzo[c][1,8]naphthyridin-6-one scaffold were identified. A crystal structure of Aurora kinase A in complex with an initial hit revealed a binding mode of the inhibitor within the ATP binding site and provided insight for structure-guided compound optimization. Subsequent SAR campaign provided a potent and selective pan Aurora inhibitor, which demonstrated potent target modulation and antiproliferative effects in the pancreatic cell line, MIAPaCa-2. Furthermore, this compound inhibited phosphorylation of histone H3 (pHH3) in mouse bone morrow upon oral administration, which is consistent with inhibition of Aurora kinase B activity.
