Aurora kinase/HDAC-IN-1

Aurora kinase/HDAC-IN-1 is an orally active dual Aurora kinase and HDAC inhibitor that inhibits Aurora A (IC50 = 116 nM), Aurora B (IC50 = 225 nM), HDAC1 (IC50 = 164 nM), and HDAC2 (IC50 = 346 nM) .Aurora kinase/HDAC-IN-1 promotes histone H3 acetylation, inhibits Aurora A phosphorylation and downstream signaling, and induces apoptosis via G2/M cell-cycle arrest. Aurora kinase/HDAC-IN-1 exhibits potent antiproliferative activity in colorectal cancer cells, with an IC50 value of 30.2 nM in HCT-116 cells.Aurora kinase/HDAC-IN-1 significantly suppresses tumor growth in an HCT-116 colorectal cancer xenograft mouse model[1].
