Simurosertib (TAK-931) potently inhibits CDC7 kinase activity (IC50 <0.3 nM) with a time-dependent ATP-competitive kinetics to its ATP-binding pocket. The selectivity studies using the 308 kinases reveals >120-fold selectivity of Simurosertib (TAK-931) for CDC7 kinase inhibition compared to other kinase inhibitions. Treatment with Simurosertib (TAK-931) suppresses the cellular MCM2 phosphorylation at Ser40 (pMCM2) in a dose-dependent manner, resulting in a delayed S phase progression, DNA-damage checkpoint activation, and caspase-3/7 activation[1].
