ON1231320 is a selective inhibitor of polo-like kinase 2 (PLK2), exhibiting an IC50 of 0.31 μM. This compound disrupts tumor cell cycle progression specifically at the G2/M phase during mitosis, leading to apoptotic cell death. The arylsulfonyl pyrido-pyrimidinone structure contributes to its significant antitumor activity, making ON1231320 a valuable tool for research in cancer biology and therapeutic development.
