== Function ==
[https://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>

== Publication Abstract from PubMed ==
The imidazo-[1,2-a]-pyrazine (1) is a dual inhibitor of Aurora kinases A and B with modest cell potency (IC50 = 250 nM) and low solubility (5 muM). Lead optimization guided by the binding mode led to the acyclic amino alcohol 12k (SCH 1473759), which is a picomolar inhibitor of Aurora kinases (TdF K d Aur A = 0.02 nM and Aur B = 0.03 nM) with improved cell potency (phos-HH3 inhibition IC50 = 25 nM) and intrinsic aqueous solubility (11.4 mM). It also demonstrated efficacy and target engagement in human tumor xenograft mouse models.
