Empesertib (BAY1161909) is an orally bioavailable, selective inhibitor of the serine/threonine monopolar spindle 1 (Mps1) kinase (IC50 of < 1 nM), with potential antineoplastic activity. BAY1161909 also shows anti-tumor effect, suppressing the proliferation of Hela cells, with an IC50 of < 400 nM. The Mps1 kinase inhibitor Empesertib (BAY1161909) binds to and inhibits the activity of Mps1, it causes inactivation of the spindle assembly checkpoint (SAC), accelerated mitosis, chromosomal misalignment, chromosomal missegregation, mitotic checkpoint complex destabilization, and increased aneuploidy.
