Hersperadin is an ATP-competitive small molecule inhibitor of Aurora B kinase, which is one of the three Aurora family kinases involved in the regulation of cell division, with half maximal inhibitory concentration IC50 of 250 nM, where the sulphonamide group of hersperadin inserts into the ATP-pocket in the catalytic cleft of Aurora B kinase and extends into the adjacent hydrophobic pocket. Hersperadin has been found to prevent the phosphorylation of Aurora B, where the Ser-10 phosphorylation of Aurora B in mitosis serves as a biomarker for mitotic progression, with IC50 of 40 nM leading to inhibition of chromosome alignment and segregation.
