== Function ==

[[http://www.uniprot.org/uniprot/AURKA_HUMAN AURKA_HUMAN]] Mitotic serine/threonine kinases that contributes to the regulation of cell cycle progression. Associates with the centrosome and the spindle microtubules during mitosis and plays a critical role in various mitotic events including the establishment of mitotic spindle, centrosome duplication, centrosome separation as well as maturation, chromosomal alignment, spindle assembly checkpoint, and cytokinesis. Required for initial activation of CDK1 at centrosomes. Phosphorylates numerous target proteins, including ARHGEF2, BORA, BRCA1, CDC25B, DLGP5, HDAC6, KIF2A, LATS2, NDEL1, PARD3, PPP1R2, PLK1, RASSF1, TACC3, p53/TP53 and TPX2. Regulates KIF2A tubulin depolymerase activity. Required for normal axon formation. Plays a role in microtubule remodeling during neurite extension. Important for microtubule formation and/or stabilization. Also acts as a key regulatory component of the p53/TP53 pathway, and particularly the checkpoint-response pathways critical for oncogenic transformation of cells, by phosphorylating and stabilizing p53/TP53. Phosphorylates its own inhibitors, the protein phosphatase type 1 (PP1) isoforms, to inhibit their activity. Necessary for proper cilia disassembly prior to mitosis.<ref>PMID:9606188</ref> <ref>PMID:11039908</ref> <ref>PMID:11551964</ref> <ref>PMID:12390251</ref> <ref>PMID:13678582</ref> <ref>PMID:14523000</ref> <ref>PMID:15147269</ref> <ref>PMID:14990569</ref> <ref>PMID:15128871</ref> <ref>PMID:14702041</ref> <ref>PMID:15987997</ref> <ref>PMID:18056443</ref> <ref>PMID:17604723</ref> <ref>PMID:17360485</ref> <ref>PMID:18615013</ref> <ref>PMID:19812038</ref> <ref>PMID:19351716</ref> <ref>PMID:19668197</ref> <ref>PMID:19357306</ref> <ref>PMID:20643351</ref> <ref>PMID:17125279</ref>

Abstract. The ortho-carboxylic acid substituted bisanilinopyrimidine 1 was identified as a potent hit (Aurora A IC50 = 6.1 +/- 1.0 nM) from in-house screening. Detailed structure activity relationship (SAR) studies indicated that polar substituents at the para position of the B-ring are critical for potent activity. X-ray crystallography studies revealed that compound 1 is a type-I inhibitor that binds the Aurora kinase active site in a DFG-in conformation. Structure activity guided replacement of the A-ring carboxylic acid with halogens and incorporation of fluorine at the pyrimidine 5-position led to highly potent inhibitors of Aurora A that bind in a DFG-out conformation. B-ring modifications were undertaken to improve the solubility and cell permeability. Compounds such as 9m with water-solubilizing moieties at the para-position of the B-ring inhibited the autophosphorylation of Aurora A in MDA-MB-468 breast cancer cells.
