It blocks the cell cycle at early S phase. It is a specific inhibitor of DNA polymerase Alpha and Delta in eukaryotic cells and in some viruses (vaccinia and herpesviruses) and an apoptosis inducer in HeLa cells.
This compound inhibits the activity of DNA polymerase Alpha and Delta during the early stages of DNA replication in eukaryotic cells and certain viruses like vaccinia and herpesviruses. Additionally, it triggers programmed cell death in HeLa cells.
