Aurora Kinases-IN-3 (Compound 15a) is an orally active AURKB inhibitor that elicits an AURKB-suppressive activity by disrupting the mitotic localization of AURKB, rather than inhibiting its phosphorylation of H3 at Ser10.
Aurora Kinases-IN-3 (Compound 15a) (40 nM; 6 h) disrupts localization of AURKB, MKLP1, and PLK at the spindle midzone to prevent spindle midzone microtubule assembly in RPE-MYCBCL2 cells. Aurora Kinases-IN-3 disrupts the localization of AURKB as early as anaphase, producing downstream consequences that blocked cytokinesis[1].Aurora Kinases-IN-3 (1-10 μM; 3 days) shows wide spectrum of growth suppression in human cancer cell lines[1].
Aurora Kinases-IN-3 (Compound 15a) (50 mg/kg; oral; twice a day for 7 days) suppresses the growth of lung tumors in mice[1].
