    Abstract: Twenty five novel chemical analogs of the previously reported Aurora kinase inhibitor BPR1K653 (1-(4-(2-((5-chloro-6-phenylfuro[2,3-d]pyrimidin-4-yl)amino)ethyl)phenyl)-3-(2-((dimethylamino)methyl)phenyl)urea) have been designed, synthesized, and evaluated by Aurora-A and Aurora-B enzymatic kinase activity assays. Similar to BPR1K653, analogs 3b-3h bear alkyl or tertiary amino group at the ortho position of the phenylurea, and showed equal or better inhibition activity for Aurora-B over Aurora-A. Conversely, preferential Aurora-A inhibition activity was observed when the same functional group was moved to the meta position of the phenylurea. Compounds 3m and 3n, both of which harbor a tertiary amino group at the meta position of the phenylurea, showed 10–16 fold inhibition selectivity for Aurora-A over Aurora-B. The in vitro kinase inhibition results were verified by Western blot analysis, and indicated that compounds 3m and 3n were more than 75-fold superior in inhibiting T-loop autophosphorylation of Aurora-A (Thr288), compared to Aurora-B (Thr232) in HCT116 colon carcinoma cells. The computational docking analysis suggested that the tertiary amine at the meta position of the phenylurea formed a more stable interaction with residues in the back pocket of Aurora-A than in Aurora-B, a possible explanation for the observed discrepancy in the selectivity. These results support an alternative small molecule design strategy targeting the back pocket of Aurora kinases for selective isoform inhibition.
